Rank #1 in Best Super King Mattress 2026: 10 Ranked, One Claims 2,000 Springs
dosleeps 6FT Hybrid Memory Foam Mattress, 10 Inch
Price and rating as shown on Amazon when we collected them. Both change.
This is the dosleeps 6FT Super King memory foam hybrid, the mattress that took first place in our super king guide. It is listed at £269.99 and carries a 4.4 rating from 3,524 ratings, with 76 of the 100 ratings in the breakdown sitting at five stars.
What makes this listing worth reading closely is that its numbers largely agree with each other. It declares 900 pocketed coils and 7 layers inside a 25 cm deep mattress — about 3.6 cm of depth per layer — and a 28.5 kg item weight, which is the sort of figure you would expect from a super king hybrid. For context, the £829 mattress in this guide declares 600 coils, and the £143.64 one declares 868. Note that the product title says 10 inches, which is 25.4 cm, while the specification fields say 25 cm. Everything on this page comes from the Amazon listing, not from any testing we have carried out.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I recently purchased this mattress, which has exceeded my expectations for comfort and support. After doing some research, I decided on a single mattress measuring 90cm x 190cm x 25cm, and I couldn't be happier with my choice.The mattress arrived vacuum-packed in a protective plastic bag, neatly boxed for easy handling. Since I was about to go on holiday, I took the precaution of laying the mattress out flat as soon as it arrived. After carefully removing the plastic covering, I allowed it to expand to its original shape for several days while I was away. I was pleased to notice minimal odour during this process, and any residual smell dissipated shortly after unboxing.Once I returned from my trip, I placed the mattress on my new bed frame. The first night was truly a revelation; the mattress was incredibly comfortable, offering an excellent balance of support and pressure relief. I found myself sinking into the surface just the right amount without losing that essential firmness. It is classified as medium-firm, and although it's a touch softer than I initially anticipated, this slight give adds to overall comfort and makes for an inviting sleeping experience.I was delighted to wake up after my first night feeling well-rested and refreshed. The support provided by the mattress alleviated pressure points, resulting in deep, restorative sleep. Having experienced various mattresses in the past, I can honestly say this one stands out in its value and quality.Overall, I am thoroughly satisfied with my purchase. The combination of affordability, comfort, and support makes this mattress a great investment for anyone seeking a restful night's sleep. I'm truly enjoying it and look forward to many more nights of comfortable rest ahead.”
Verified purchase“Needed to replace a 10 year old mattress which cost almost a £1000 , ordered a smaller one for my mum previously and was so impressed with the comfort for such a bargain price that I ordered a king size one for myself,it came vacuum packed so easy to transport upstairs and within minutes of opening became a fully plumped up bed . Can't believe how comfortable it is ,like sleeping on a marshmallow!”
