What size is a Simba single bed mattress?

These single bed mattresses are a UK single size, measuring 90cmW x 190cmL; we also offer the slightly longer, European Single mattresses in our Organic and Hybrid ranges. The depth of each single mattress varies according to the model, so please check the product details on your chosen mattress. If you have enough space you might also want to consider a Small Double Mattress, or a Double Mattress, especially if you have growing kids.Head over to All Mattresses for more details about our range.

What to consider when choosing a single mattress

All our single mattresses arrive boxed so they’re easy to manoeuvre up the stairs but do check that a single mattress is the best size for your bedroom.Once you’ve put your tape measure away, you need to consider who your new single mattress is for, and how often it’s going to be used: bear in mind for example it will get heavy use from kids and teenagers, who will also need good support and space as they grow (and don’t forget if you’re buying a single mattress for a bunk bed you need to choose a one with a shallower depth).Single mattresses are also a great option for guest rooms, either on their own or in a pair; Simba single mattresses offer cooler comfort at a wide range of prices to suit your budget.

How firm are Simba mattresses?

Our mattresses are designed to offer perfect, consistent support to your body, rather than being firm or soft.So what is perfect support? 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 perfect 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.

Why is the Simba Hybrid® single mattress unique?

Simba’s award-winning, patented mattress technology underpins all our Hybrid® single mattresses – it’s earned us the accolade of the world’s most 5-star rated mattress brand. Whether you sleep on your front, side or back, the unique combination of our responsive Aerocoil® springs and our airy Simbatex® foam ensures the perfect balance between tailored support and superior cushioning that your body needs.

Do Simba sell a single mattress that’s suitable for bunk beds?

Yes. Single mattresses for bunk beds or cabin beds require a shallower depth for safety reasons; we recommend our Hybrid Kids Mattress which has a depth of 16cm for any top bunk or raised bed.

My child gets hot at night. What’s the best single mattress for kids and teenagers that overheat?

We have a wide range of single mattresses at different price points, but they’re all packed with Simba sleep tech and the best materials to keep you cooler. But for overheating kids and young people whose shape is constantly changing, we particularly recommend our Hybrid Pro and our Organic Go mattresses as good all-rounders offering optimum temperature control and responsive support.

How to care for and maintain your single bed mattress

There’s no need to turn it over to prolong its life, but we do recommend you rotate your single mattress head to foot once a month for the first three months. After that it’s a good idea to do this seasonally.A Simba single bed mattress features a removable cover which you can remove and wash, but we also recommend you get one of our machine washable, quilted cotton Mattress Protectors to help keep your new single mattress fresh and clean.

I want to help fight climate change. Do you sell refurbished single mattresses?

We’re proud that most mattresses returned to us are refurbished by our expert renewal team; it saves a huge amount of energy and materials, plus it brings Simba’s unique sleep tech within everyone’s reach. Because everyone deserves a great sleep night’s, right?So yes, we definitely do sell refurbished single mattresses; they’re all 100% tested, sanitised, and certified by Simba, and include a 1-year guarantee.Check out our range of Refurbished Mattresses.

No, standard delivery takes place within 48 hours and is free of charge, even in single mattress sale periods.

Is there a free trial period on Simba single mattresses?

Yes, you have a whopping 200 nights to try our single mattresses without losing your right to return free of charge: if you’re decide you’re not happy within that time, we’ll collect it for you for free.
