What to consider when choosing a double mattress

It’s easy to under or overestimate how much space you have available. So it’s a good idea to measure out the dimensions of your double mattress, making sure there’ll be enough space to open doors and cupboards. But don’t worry about whether you ‘ll be able to get it up the stairs, because all our double mattresses are delivered vacuum packed and boxed.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.

Choosing the right Simba double mattress

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.So what is perfect support? It’s about having the exactly the right balance between a top layer that compresses in response to your body, and an underlying layer that gently resists that response. Without the top comfort layer you’d feel like you were sleeping on a plank, but without the support layer you’d feel like you were sleeping on a trampoline.

What's so special about a Simba Hybrid® double mattress?

It’s all down to our award-winning mattress technology. Our exclusive Hybrid® double mattress designs are a unique blend of our patented Aerocoil® springs and our cushioning Simbatex® foam; together they offer unrivalled, contoured support and superb pressure relief.

How to care for your Double Mattress

There’s no need to turn your double mattress over to prolong its life; just rotate it head to foot once a month for the first three months, then every quarter after that.We also strongly recommend one of our machine washable, quilted cotton Mattress Protectors to help keep your double mattress fresh and clean.

Will my new double mattress qualify for Free Delivery & Returns?

Yes, even in our double mattress sale periods! Standard delivery is free for all our mattresses, with most designs arriving within 48 hours. Returns are free too; you have 200 days to decide whether you are happy with your purchase, and if not we’ll collect it from you free of charge.
