Product Information

We also strongly recommend one of our machine washable, quilted cotton Mattress Protectors to help keep your double mattress fresh and clean. During our review period, our lead reviewer found the Simba Hybrid mattress was comfortable from the first night, especially for side sleeping, although a couple of stomach sleepers on our testing panel found the mattress too firm. The Simba felt breathable, and the motion isolation was also very good – the co-sleepers on our testing panel weren't disturbed by each other getting in and out of bed. If you are looking for support, the Simba Hybrid mattress has plenty of it. However, when it comes to pressure relief the amount of comfort depends a bit more on your body weight and sleep position. Our heavier weight tester commented that they felt cushioned no matter how they slept on this mattress, with their shoulders, hips and knees feeling comfortable with no pressure. The result? You can rest assured our range of Refurbished Mattresses will give you the full Simba experience, at a fraction of the price.

The small double Simba Hybrid we reviewed measured 120cm x 190cm x 25cm. As such, we expected it to be a little easier to move around than a double or king. The box measures 107cm x 50cm x 50cm, so it wasn’t cumbersome, however at 24kg in weight, if you need to get it up stairs or into a different room, you will probably need an extra pair of hands to help you.

Without sounding too obvious, we test our mattresses by sleeping on them. While it seems like a cushy job, there are a variety of factors we take into consideration. With the inclusion of comfort and support, we focus on firmness and temperature control – though, when necessary, we will also pay attention to motion isolation and edge support. A double bed mattress is the perfect size for stretching out, without swallowing up the entire room; it’s a great option for growing teens, smaller bedrooms and guests, but could be a squash for some couples. Before we make a final judgement, we take any trial runs that might be on offer into account – which is often the case within the bed-in-a-box market – before asking the important question, is the product good value for money? Most of our mattresses are available in standard UK and European sizes (please note that mattress depth varies depending on the model you choose):

Yes. All Simba mattresses are 100% recyclable, so there’s no need for any Simba mattress to go to landfill at the end of its life. In fact for a small fee we offer a removal service for your old mattress whenever you buy a new one from Simba; whatever the brand or size, we’ll make sure it’s properly and responsibly recycled. We tested the Simba Hybrid in a small double size for four weeks before writing our review. We focused on performance, rating it on pressure relief, motion isolation, temperature regulation, edge support and durability, as well as ease of set-up.When compared to the competition, which we would class as the Nectar Hybrid, the Eve Premium Hybrid and the Emma Premium, among others, Simba’s RRPs are slightly cheaper. That said, depending on the mattress sales that are live at any one time, Nectar, Simba and Emma can often undercut. Our mattresses are easy to care for; all you need to do is rotate them once a month for the first three months, and then roughly every quarter after that. You don’t need to turn them over at all. Absolutely. All our mattresses come with a 10-year guarantee; Simba certified Refurbished mattresses include a 1-year guarantee. If you are after an extra layer of comfort, support or cushioning, then the Simba Hybrid Pro with double support could be a better fit. For the ultimate Simba experience, look no further than the 31cm-deep Hybrid Luxe with its plushness and other cosy qualities delivered across ten layers. Woken up by a fidgety partner? Too hot to sleep? All our double mattresses are engineered to keep you cool, comfortable and of course perfectly supported, whatever your sleeping style.

Simba used 70 prototypes and the “body data of 10 million sleepers” to create the original Hybrid mattress. The five-layer design includes titanium coils and a layer of open-cell graphite-infused Simbatex, which is designed to be a more breathable version of memory foam. While the Simba Hybrid can feel a little firmer for lighter weights, the sensation of resting on top of the mattress rather than in it is still by no means uncomfortable, and the top layer conformed just the right amount to the body, which was extremely cosy. From the minute you place your hand on the Simba Hybrid mattress, it’s clear that this will be a comfortable snooze. But, as with any bed, your body weight and sleeping position will matter greatly when it comes to true comfort. For our testers, the most comfortable sleeping position was on the side, with pressure points feeling noticeably cushioned. Buying a mattress isn’t an easy task, so it’s worth doing plenty of reading before making the plunge. If you still have unanswered questions, below are a few of our guides and best buys that should help answer them:After this comes the Aerocoil spring comfort layer, where up to 2,500 conical springs isolate motion and distribute weight evenly across the Simba Hybrid. Below the coil layer is CertiPUR-certified toxin-free Simba-Pure foam to keep you supported no matter where you sleep on the Simba Hybrid. There’s a helping of Edge Lift Technology here too, so you won’t feel as though you’re falling out of bed if you sleep right up to the edge.
