Small-Double mattresses

Our small-double mattresses are a standard UK small-double mattress size, measuring 120cmW x 190cmL with a minimum of 25cm depth depending on the range and model. You might also know them as three-quarter mattresses or 4ft mattresses. The small-double size is available in our Hybrid®, Hybrid® Essential, Hybrid® Pro and Hybrid® Luxe models. If you want a little more space, upgrade to a Double mattress, King Size mattress or Super King mattress from the rest of our collection, including our natural mattress Earth range.

Since small-double mattresses are slightly narrower than standard UK double mattresses, we don’t often recommend them for couples. Instead, their extra width can make them an ideal choice for growing kids and teenagers. Their changing body shape and sleeping habits can benefit from the support of our signature Simba tech. 

If you don’t have room for a small-double, you’ll still get the same ground-breaking tech in our Single Mattresses and our Kids Mattress, which is suitable for bunk beds. 

Whenever you buy a small-double mattress from Simba, you can be sure we’ve designed it for optimum support and a fresher sleep. That’s all thanks to our unique blend of innovative technology, superb quality materials and many years of expertise.

Yes, we offer a range mattress sizes across our collection – including UK standard double mattresses. If you’re looking for something slightly roomier, you might want to consider our wider European Queen Size Mattresses, King Size Mattresses and Super King Mattresses. And if you’re limited on space, our UK Single mattresses contain the same signature Simba tech on a smaller scale. 

Whatever size you choose, all our Hybrid® Mattresses offer signature Simba tech at a wide range of prices, plus our Earth range features a unique blend of Simba tech with some of Nature’s best materials.

Our mattresses are designed to offer responsive support to your body, rather than being firm or soft. 

So what does that feel like? It’s about the correct balance between a top layer that reacts to your body shape and weight, on top of a layer that gently stops that response. For optimum support to be achieved you need both these layers and their functions: without the responsive comfort layer it would be like sleeping on a wooden plank, without the firmer support layer it would be like sleeping on a bouncy trampoline.

Simba’s award-winning mattress technology underpins all our small-double Hybrid® mattresses. Whether you sleep on your front, side or back, the unique combination of our responsive Aerocoil® springs and our Simbatex® foam is designed to offer tailored support and comfort for your body. And that goes for all the mattresses we make.

There’s no need to turn it over to prolong its life, but we do recommend you rotate your Small-double mattress head to foot once a month for the first three months. After that it’s a good idea to do this once every three months for the rest of its life.  

Most Simba small-double bed mattresses feature a removable cover which you can wash, but we also recommend you get one of our machine washable, quilted cotton Mattress Protectors to help keep your new small-double mattress fresh and clean. 

We strive to refurbish or recycle all the mattresses that are returned to us in their trial period; it’s kinder to the planet to give mattresses another life, since we’re keeping them from landfill – and it keeps our unique Simba sleep tech within everyone’s reach, since they’re more affordable than brand new mattresses. Because everyone deserves a great night’s sleep. 

So yes, we definitely do sell refurbished small-double mattresses. When you send them back to us, they’re 100% tested, sanitised by our trusted third partner and certified by Simba, and include a 1-year guarantee.

We’re committed to sending no mattresses to landfill, so that’s why all the small-double mattresses for sale at Simba are suitable for recycling via our collection service or specialist providers. If you return your mattress in your 200-night trial (or under our 10-year guarantee), they’re refurbished. Those with too much wear and tear are recycled. When your mattress reaches the end of its life, we have a specialised Simba Mattress Recycling Service on our site. Simply pay a small fee, and we’ll collect it for you. That’s any brand, any size – no Simba purchase necessary.

Yes, we offer guaranteed free delivery on your small-double mattress, even in sale periods. It’ll arrive conveniently rolled and boxed, just give it a couple of days to fully regain its shape. You’ll also get a 200-night free trial period. If you’re not happy withing that time, let us know and we’ll collect it for free.

There’s no universal industry system that rates one so-called ‘firm mattress’ against another. But we believe a medium-firm small-double mattress is most likely to offer the comfort our customers are looking for, so we’ve created our Hybrid® mattresses accordingly. They’re designed to offer supportive body alignment alongside soothing pressure relief.
