We conduct seven robust tests in our lab to capture objective data on the four areas of a mattress that most affect your sleep comfort: pressure relief, temperature regulation, motion isolation and edge support. We also sleep on a mattress for at least three weeks before subjectively rating it. All of this data is fed into our bespoke scoring system, along with feedback captured by our expert testing panel, to create an overall review score. Read our full mattress methodology here.
The Siena Signature Mattress is a budget-friendly memory foam bed that has cemented its place in our best mattress guide: it's our top cheap mattress recommendation.
Considering its pedigree, it’s no surprise the Siena impresses; it’s from Resident Home, the brand behind the popular Nectar and DreamCloud mattresses. The Siena can’t quite compare to its cousins but it is almost half the price.
Don't expect a soft, traditional foam feel here: this is a firm mattress — but the memory foam cushioning keeps it comfortable for all but the heaviest bodies. And that firmness translates into excellent support, making it ideal for back and stomach sleepers.
Most side sleepers, however, will need more pressure relief. The Zinus Green Tea Mattress and the EGOHOME Black Memory Foam Mattress are softer alternatives, although lacking the Siena’s overall performance. Because the Siena shines where other cheap beds stumble: it’s breathable, supportive all-over, and absorbs motion — few of its competitors can claim the same.
Value for money: 4 out of 5
We’ve been tracking the price of the Siena Signature Mattress for several years now and the good news for bargain hunters is that this is always a budget-friendly bed. Siena has switched the MSRP for a ‘Total Value’ amount, but thanks to a permanent, year-round sale, you can go ahead and ignore this number. Typically, you can expect to pay around $359-$399 for a queen.
Here’s how much you can expect to pay for the Siena 10-inch Signature Mattress:
Siena mattress sales run throughout the year and the prices rarely change — don’t expect bigger drops for Black Friday or Memorial Day. The price does change occasionally (for example, a queen was $399 earlier this year) but these drops are hard to predict.
This price range places the Siena in a similar category to the EGOHOME Black Memory Foam Mattress (often $369.99 for a queen) and the Zinus Green Tea Mattress ($499 for a queen, but often reduced on Amazon.) It’s rare to find a good quality mattress in this price category but we consider all three excellent value.
One area where the Siena strides ahead of its budget competitors is benefits. Most value mattresses come with minimal extras, but Siena offers both a 10-year mattress warranty (considered the industry average) and a 180-night sleep trial. This is ample time to test it at home and it’s an even better trial period than some luxury brands — both Tempur-Pedic and Helix offer less.
If you’re on the hunt for a deal, we also recommend heading to the Siena Amazon store. Here we’ve spotted a queen-size 10-inch Memory Foam mattress for as little as $288. The biggest downside is that these offers aren’t always available and sometimes confined to Prime members.
Considering the price, benefits and overall quality of the Siena, we think this bed is incredible value for money: you’ll struggle to get anything better in this price category. However, if you have a bigger budget, we think upgrading to the Nectar Classic Memory Foam Mattress ($649 for a queen) will provide you with a more durable sleep sanctuary.
Design
- 10-inch tall, all-foam mattress
- Contains two layers of foam
- Simple design likely contributes to the low price
The 10" Siena Mattress is an all-foam bed that uses two layers of foam to create comfort and support. This streamlined build likely contributes to the cost-effective nature of the bed (many of the best memory foam mattresses have three plus layers) but don't mistake 'simple' for 'bad.'
Sitting beneath a breathable fabric cover is a layer of gel memory foam, designed to add contouring and pressure relief. Beneath this is a thicker layer of sturdy base foam, to enhance support and longevity. At the bottom is an outer cover, to increase durability.
Previously, for an extra $49, Siena allowed customers to add antimicrobial protection that the brand claimed kills and prevents 99.9% of bacteria that can affect the lifespan of a mattress. (This option is no longer available.) In any case, you'll want to wrap your Siena Mattress in one of the best mattress protectors to also safeguard it from spills and stains.
Comfort: What it's like to sleep on
The moment I climbed on to the Siena Signature mattress, I was obsessed with its support. I’d been restless on my previous bed — the Nectar Premier Memory Foam is too soft for me — but on the Siena, I settled quickly into a comfortable stomach sleeping position and stayed that way.
Our Sleep Editor Nicola Appleton was similarly full of praise, this time for its “soothing” back sleeping support. She also appreciated the motion isolation. As a bed sharer, she felt that even extreme restlessness from her partner wouldn’t bother her on the Siena.
If you go in expecting a soft, traditional foam feel it's going to be a shock: from my testing, it's firmness is second only to the very firm Plank Firm mattress — but its cushioning stops it from feeling like you're lying on the floor. I found it very comfortable in most positions.
The Siena does lack pressure relief though and I found a whole night spent on my side resulted in a numb arm. This goes double for side sleepers with small builds: our lightest tester much preferred the EGOHOME Memory Foam Mattress. I did test the 10-inch standard model, however: 12-inch and 14-inch upgrades are available and these thicker designs might have more pressure relief.
However, the firm build does come with the benefit of strong edge support. I can starfish without worrying I’ll slip off.
Temperature control: 3.3 out of 5
Heat closely impacts sleep quality and a mattress with poor temperature regulation will trap warmth to create a stuffy sleep environment. In the worst case, overheating can lead to night sweats and disrupted sleep.
With no cooling features bar a ‘breathable’ cover, we wouldn't expect the Siena to sleep cool. But although it received a lower score in our objective lab tests, we consider it among the best cooling mattresses we've tested — as a budget option — thanks to our real-world experience and tester feedback.
Our thermal imaging camera showed a large heat spike within the first minute of testing (8.1°F). The mattress then remained at a fairly consistent temperature, before dropping significantly (shedding 6.2°F of heat) as soon as our tester left the bed. It's fast cooling rate of 1.52°F/min was beaten only by the Bear Elite with Celliant-infused cover at 1.82°F/min.
However, it was the slowest of all its rivals in our best mattress guide to return to its base temperature: it took 14 minutes to get within one degree. The Bear Elite, by comparison, took just three minutes. This indicates some lingering warmth, which is typical of a memory foam mattress.
The Siena had a similar performance to the Nectar Premier in our testing — another memory foam mattress that lacks the larger suite of cooling features you'd find in a mattress like the Bear Elite Hybrid. The Nectar did, however, outperform the Siena with a lower maximum temperature increase (MTI). But it's worth noting the Nectar Premier is more expensive than the Siena and comes with a ‘cool to the touch’ cover — we’d expect a stronger performance from that mattress.

A better comparison mattress to the Siena might be the Zinus Green Tea (although we’ve yet to use our thermal camera on the Zinus.) I’ve slept on both the Zinus and the Siena in similar circumstances and while I often woke up sweating on the Zinus, I remained a comfortable temperature all night on the Siena.
Our thermal camera showed the Siena's temperature did climb to a maximum of 9.8°F the longer our tester spent on it (that's an extra 1.7°F from its initial spike.) This shouldn’t be a problem for most, but hot sleepers might find the mattress continues to warm throughout the night.
To be honest, in the Siena’s price bracket, you’ll struggle to find a mattress with better temperature regulation. Memory foam mattresses are known to hold onto heat but the Siena avoids significant temperature build-up to retain a neutral feel, earning it 3.3 out of 5 in our testing rubric.
If you have a slightly larger budget and you're open to a hybrid, the DreamCloud is a good value alternative (it had an MTI of 7.3°F and dispersed all excess heat within six minutes.)

Pressure Relief: 3.76 out of 5
A mattress with good pressure relief will use both contouring (adapting to the body shape) and support (holding the body aloft) to prevent pain building up. We awarded the Siena Mattress 4 out of 5 for pressure relief — a strong score but for side sleepers, it comes with a caveat.
The Siena excels at support but the simple two-layer design, featuring only a thin layer of contouring foam, means it lacks cushioning. This is reflected in our studio testing. We placed a 25kg weight (roughly one-third the weight of the average American) at the shoulder and hip area of the mattress, measuring an average sink of 3.625 inches. This was less sink than on any of the other mattresses we've tested (the next closest is the Nectar Premier at 4.125 inches.) This shows how little contouring there is compared to other beds; you’re going to be lying on top of the foams.

During our human pressure relief tests (lying on the mattress in front, back and side sleeping positions for 10 minutes each) we lined up a laser with the approximate position of a straight spine. After 10 minutes, the laser line and the spine remained in alignment. This shows consistent support and every member of our testing team rated it highly for support in all sleep positions.
However, while supportive in all sleep positions, the Siena lacks the contouring expected by most side sleepers. We recommend a bed with a thicker or softer comfort layer, instead. The Siena has 2 inches of comfort foams compared to 3 inches in the Saatva, plus a layer of contouring microcoils.
The Siena also lacks a transition layer, a responsive foam that sits between the comfort materials and the support base. Without a transition layer you can feel more of the Siena's support foams, which likely contributes to the firmer feel (from a subjective view point, I felt like I sank into the comfort foams easily but made minimal impression on the support foams beneath.) So while the Nectar, like the Siena, only has 2 inches of comfort foam, the additional 3 inches of transitional foams likely contribute to its more cushioned feel.
The Nectar Premier has thicker comfort layers for better cushioning (although the Nectar lacks support for back and stomach sleeping.) Or for a cheaper option, the Zinus Green Tea Memory Foam Mattress has a plush cushioned feel.
Firmness
Mattress firmness is highly subjective (it’s closely related to body type and sleep position) making it a hard metric to nail down but our team was unanimous that the Siena is a firm mattress. It requires significant force to make an impression on the mattress and once you’ve pushed into the top comfort layer, the support layer beneath is unyielding.
Collectively, we rated the Siena Signature Mattress an 8/10 on the mattress firmness scale (a standardized scale where one indicates soft and 10 hard.) This score reflects both our subjective experience and the lack of sink shown during our weight tests. That’s a significant difference from the medium-firm ‘sweet spot’ Siena describes the mattress as. The Nectar Premier is also described as a 6.5 and we found this rating more accurate.
The Siena's firmness is immediately apparent — you lie on top of the foams rather than sinking in. This creates an even support to hold your body in a straight line, reducing pressure on the lower back. Due to this, the Siena is one of the best mattresses for stomach sleepers we've tested. I'm a stomach sleeper and find the Siena delivered relief comparable to the Plank Firm mattress.
Our tester Nicola admitted that even though she would “never” sleep on her stomach, she was comfortable lying on her front, although she preferred the “soothing” feel when back sleeping.
The flipside is that the lack of pressure relief and firm feel means the Siena Mattress largely won’t suit side sleepers, particularly those with a lightweight build (our lightest tester couldn’t get comfortable at all.) While the average weight testers could enjoy “short bursts” of side sleeping, suitable for combination sleepers, we think dedicated side sleepers will prefer a mattress with thicker comfort layers to deliver more cushioned pressure relief. The Zinus Green Tea is a good alternative, which we rated as 6 out of 10 on the scale.
While heavier weight sleepers might find the Siena Signature Mattress comfortable due to its sturdy support, we hesitate to recommend this mattress to anyone weighing over 250lbs. As a cheap bed it likely lacks the durability displayed in the best mattresses for bigger bodies.
Motion isolation: 4.6 out of 5
For co-sleepers, motion isolation is a key performance indicator in a mattress. Motion isolation, or motion control, determines how well a mattress stops disruptive movement traveling from one side of the bed to the other. If a mattress has excellent motion isolation, you can sleep through a restless partner. Bad motion isolation, and even minor shifts might bother you.
To objectively test motion isolation, we drop a 5kg slam ball on a designated area (roughly where a person would sleep) and measure the force and duration of impact with an accelerometer app, running on a smartphone strapped to the other side of the mattress (roughly where your partner would sleep.) We repeat this 10 times and take an average.
The Siena Signature Mattress had an average IIA (initial impact absorption) of 5.527ms/2 — that's the immediate force absorbed by the accelerometer. This is the lowest of any mattress we've tested, beating even the Saatva Classic (which has an IIA of 7.863.)
Siena Signature: motion isolation test results
The lower the initial impact (IIA), the better the mattress is at dampening the original force, meaning there's less motion to transfer

| Product | Value (m/s2) |
|---|---|
| Siena Signature | 5.527 |

Decay rate

| Saatva Classic | 1.703 |
| Nectar Premier | 2.546 |
| DreamCloud Classic | 3.22 |
| Bear Elite Hybrid | 3.504 |
We measured the decay rate at 1.14 seconds, the quickest of our tests by a wide margin (the second best, the Saatva Classic, has a 1.73 second average decay rate.) That earns it a score of 4.6 out of 5, or excellent, in our motion testing rubric. While there is a moderate initial spike, the mattress quickly dampens the vibrations, meaning you might notice a co-sleeper move but it shouldn't bother you for long.
As an all-foam mattress, we expect the Siena to offer good motion isolation (it's a common feature across the best memory foam mattress.) In this testing it outperformed all our hybrid mattresses, suggesting if you share a bed with a restless sleeper, the Siena's dense foam layers can prevent disruption.
The Siena Signature 10-inch mattress also impressed our hands-on testers, who agreed even high intensity movements, like quick position changes, were unlikely to disturb them. One tester noted they didn’t realize the other person had left the bed until their voice came from the other side of the room — great if you and your co-sleeper are on different schedules.
Edge support: 4 out of 5
Edge support describes how stable a bed is at the perimeter — can you sit on the side without sliding off? Does the edge collapse beneath you when you push against it? It’s a useful feature for anyone who likes to starfish but particularly important to bed sharers (who need the full surface of the mattress) and those with limited mobility (who might need a sturdy edge to maneuver on and off the bed.)
The Siena Mattress is supportive all-round and that extends to its corners. We had no problem balancing a 25kg weight on the foot of the Siena and its compression of 3.06 is lower than any of our top mattresses (the Saatva has integrated enhanced edge support and still had a compression of 3.625 inches.) The sink is comparable to the measurement we observed in the 'sleeping area' of the mattress, indicating you'll be just as supported sitting on the side as you will lying in the center.

Less compression means better support when sitting on the edge of the bed

During our roll off test, our second tester found she could use almost the whole surface of the Siena mattress. Her hip measurement (13.5 inches) + the point at which she felt uncomfortable (44.5 inches) - the width of the mattress (60 inches) = a sleep surface of 58 inches. It’s not as good as the total sleep surface of the Saatva (60 inches) but considering edge support is a literal weak spot of most low cost beds, the Siena performed well for its price bracket — only the EGOHOME Memory Foam Mattress comes close.
One member of our testing panel did have an issue with the edge support of the Siena: my mom. She has trouble with her knees and disliked how the Siena “started to sink down straight away.” I would attribute this to comfort layers of the Siena, which do present initial sinkage, but once you’re past that the sides are stable.
Customer reviews
To offer our readers a well-rounded perspective, we've analyzed user reviews from verified Siena customers.
The Siena Signature Mattress is rated 4.5 stars out of 5 from over 3,200 Reviews reviews on the Siena Sleep website. Currently, there's no way to filter reviews according to customers' sleep styles or top concerns, but you can sort them by rating, date, and helpfulness.
While there's some conflicting opinions over firmness (as I said, firmness is subjective) the majority of reviews find the Siena to be a firm bed. Many credit the Siena with alleviating aches and pains, although some negative reviews complain it overheats.
I suspect many of these reviews refer to previous models of the Siena, as it's undergone minor design changes over the years. However, the Tom's Guide team has tested several iterations of the Siena mattress and found the design changes have made minimal difference to the feel.
Should you buy it?
The Siena Signature Mattress is a dream for shoppers on a budget looking for a low-cost bed that delivers full body support and comfort.
Following our tests we scored the Siena Signature Mattress highly for motion isolation — 4.6 out of 5 is the best in this guide — and edge support (4 out of 5.) While temperature regulation got a 3.3 out of 5, falling behind the other mattresses in our top 5, the Siena still shed heat effectively and we found it sleeps cooler than most beds we've tested in this price bracket. The lack of contouring makes the Siena uncomfortable for side sleeping and bought the pressure relief score down to 3.76 out of 5, but the support is a dream for back and stomach sleepers, with some contouring to keep combination sleepers happy.
It’s important to place these scores within the price of the Siena Mattress. With a queen typically $359, we gave the Siena a score of 4 for value — it's not a luxury bed but it's well made and comes with better than usual benefits (a 180-night trial is longer than many boxed beds.) Combined with a strong performance across our testing, we awarded the Siena Signature Mattress 4 stars overall.
The Siena Signature Mattress is best for shoppers looking to replace an old mattress on a small budget. The foams deliver a high quality feel at a low price, which is why we awarded it strong marks for value.
This mattress will also suit those who need support, particularly back and stomach sleepers. The firm feel with only minimal sink keeps the body lifted from head to toe, to reduce back pain. It’s similar to the exceptional support of the Plank Firm Mattress (although without the Plank Firm’s dual comfort.)
We also think the Siena Signature is a good mattress for couples, due to its top-notch motion isolation and strong edges resulting in good support across the sleep space. The firm feel might not be the crowd pleaser of something like the medium-firm Nectar Classic Memory Foam Mattress, but we think combination sleepers will be comfortable in most sleep positions (and won’t bother their co-sleeper with tossing and turning.)
For dedicated side sleepers, however, we recommend a mattress with more pressure relief. Our Zinus Green Tea Memory Foam Mattress review team agreed this low-cost bed excels at cushioned pressure relief and in our EGOHOME Memory Foam Mattress review, we praised its side sleeper comfort.
The Siena is also unlikely to deliver the durability of a pricier mattress, so if you have the budget, consider upgrading to the DreamCloud Classic Memory Foam Mattress. It has a similar supportive feel but at $799 for a queen (and with a lifetime warranty) we predict better longevity.
Siena Mattress competitors
From the same parent brand as the Siena, the Nectar Classic Memory Foam mattress is the slightly more advanced — and more expensive — alternative to the 10-inch Signature. The medium-firm feel ensures the Nectar suits a wide range of sleep styles but don't expect much of a foam 'hug' here; while the pressure relief is good, this isn't a contouring bed. A queen typically costs $649 in the sale and we expect better longevity compared to the Siena.
A frequent Amazon bestseller, the EGOHOME 12" foam mattress delivers a squishy, contouring feel that's ideal for side sleepers. The lead tester in our EGOHOME 12" Black Memory Foam Mattress review often struggles to find a bed with enough pressure relief and the EGOHOME's cushioning impressed even her (although restless sleepers should be warned it can be hard to change position.) In regular sales, a queen is reduced to $369.99 (was $699.)
While the Siena has many advantages, the one place it falls short is for side sleepers — which is where the Zinus comes in. In our Zinus Green Tea Memory Foam Mattress review we praised its cushioned feel that suits side sleepers (this was a slightly older model but we predict a similar feel from the new design.) A queen often sells for $499.99 in the year-round Zinus mattress sale but look out for third-party deals, as both Walmart and Amazon sell Zinus.
