When it comes to the best mattresses you can buy in 2025, four models from Simba stand out – and for good reason. Since launching in 2015, this British bed-in-a-box brand has built a strong reputation in the mattress world. But with several models that sound similar and vary widely in price, figuring out which one is right for you can be a bit overwhelming.
As someone who’s reviewed everything from budget mattresses to high-end luxury options, I’ve learned what really matters for a good night’s sleep. Over the years, I’ve tested a number of Simba mattresses, and some of them genuinely rank among the best I’ve slept on. At the top of that list is the Simba hybrid luxe, which is the brand’s most premium (and priciest) model.
The hybrid luxe boasts a complex nine-layer construction, combining micro springs, breathable foam, and Simba’s signature open-cell technology, along with a wool and bamboo layer for extra airflow. It all sounds impressive on paper – but what I really wanted to know was: does it actually live up to the hype?
Keep reading for my full in-depth review of the mattress, where I test everything from delivery and setup to design and comfort. Read our full buying guide of the best mattresses.
How I tested
I first started testing the Simba hybrid luxe mattress more than a year ago, initially spending three months sleeping on it. Since then, it has become a mainstay in my bedroom, and I (and my husband) have slept on it every single night.
- Delivery and set-up: I considered how convenient the bed-in-a-box design was, helping you get your mattress home from the shop or through your front door and up the stairs without knocking all the pictures off the walls. The mattress is also available online, with ultra-quick delivery, a generous trial period and no-quibble return policy. I paid close attention to how simple it was to unpack the mattress, including the time needed to expand, and if there was any off-gassing.
- Value for money: Price and value for money were key factors. I looked at how the mattress balanced cost with quality, comfort, and durability to make sure you’re getting your money’s worth. Prices for the mattress in this piece is for a double, but it’s also available in other sizes, ranging from single to super king and various EU measurements.
- Comfort: I assessed the comfort the mattress offered, from the sleep quality throughout to night to how rested I felt in the morning. I considered how the mattress felt in different sleep positions, as well as cushioning, pressure relief, and overall support.
- Support: Equally important to a good night’s sleep, I considered how the hybrid helped me maintain proper spinal alignment. I wanted the mattress to offer firmness without feeling too rigid.
- Motion transfer: I tested how well the mattress isolated movement to see if I could sleep undisturbed, even with someone tossing and turning beside me.
- Temperature regulation: I tested the mattress at different times of the year to see how it performed year-round. I noted how warm or cool it felt and whether it was made with breathable materials like foams or cooling fabrics.
Overall, I wanted to see how it affected my sleep and whether it’s worth the four-figure price tag. Spoiler: the hybrid luxe has been chosen as IndyBest’s best overall buy in our guide to the best mattresses of 2025.

Design and features
Like all Simba mattresses, the hybrid luxe arrived rolled up inside a box. While it was heavy to manoeuvre, I managed to hoist the mattress onto my bed and leave it in place for a few hours, to increase to full size.
My first impression after unwrapping the mattress was its impressive height, which is 31cm. I sampled the double size and found a standard sheet felt a bit snug, but on the other hand, the mattress’s depth immediately made the hybrid luxe look substantial when placed on the bed base. I liked the grandeur it added to my sleeping space, and thought this reflected the premium price point, too.

Make no mistake, the Simba hybrid luxe has the appearance of a robust, hard-wearing mattress. The reason for that? It has a whopping nine layers, including a foam base element made using recycled fibres, which is a new addition compared with its previous incarnation. This updated layer sits just above the supportive grey base and has been created with minimising foam waste in mind.
Meanwhile, its other components include a bamboo and wool layer, and these materials are renowned for offering temperature regulation. Therefore, they help support cosiness in winter and coolness during the warmer months. This sits above an open-cell foam section, and both of these layers are there to offer breathability, which can often be something that is lacking in standard memory foam mattresses.
Below this, there are three luxurious layers of springs for support (two layers of titanium alloy springs, plus another layer of micro springs) and an additional foam layer. The clever way these springs have been positioned means they don’t dig in as you roll over in bed, but they do help contribute to an overall level of firmness and support.
The mattress is finished with an anti-allergy cover layer, which is quilted, feels super soft to touch and offers supreme comfort without squishiness. It’s worth knowing that the top cover can be removed for washing, so you can keep this nice and clean, too. However, it’s not suitable for tumble drying or ironing.
Comfort
The hybrid luxe mattress hits that sweet spot between medium comfort and firm support – while it's firmer than other mattresses I've tried before, it doesn’t feel overly hard, and the foam layers mean it has a responsive surface. However, there is a little motion transfer. It’s not the end of the world, but something to consider if you have a particularly restless partner.
As well as appreciating its luxurious depth, I found the mattress felt fresh to sleep on, thanks to its combination of breathable and temperature-regulating materials. I've never had an issue with overheating while sleeping on the Simba hybrid luxe, and although the surface doesn’t stay completely cool, it doesn’t retain your body heat, which is a marked improvement to some other foam mattresses I’ve tried.
Plus, it made a noticeable difference to my back and hips, which were well supported while lying in bed. Because of this, I think it’s a particularly great mattress for back and side sleepers.

While I noticed a slight sink when resting on the mattress at first, this is a welcome and subtle element, rather than an annoying sag, because the combination of layers simultaneously holds up a level of firmness underneath. After a full year of sleeping, it continues to feel firmly supportive all over.
Throughout testing, I’ve found the mattress to be supremely comfy and sumptuously supportive. In fact, I would go as far as to say the Simba hybrid luxe mattress has transformed my sleep, leading to an increased feeling of restfulness at bedtime.

The verdict: Simba hybrid luxe mattress
I’ve absolutely loved sleeping on Simba’s hybrid luxe mattress, and have found the nine layers have contributed to restful relaxation and helped provide a generous level of back support. The hybrid combination delivers fresh breathability, medium firmness, and supreme comfort. Plus, its impressive height adds to the luxe appeal and creates a robust feel.
