This Simba mattress transformed how I sleep – here’s why I’ll never look back

When it comes to the best mattresses, 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.

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.
