Rank #3 in Best Super King Mattress 2026: 10 Ranked, One Claims 2,000 Springs
dosleeps 10.6 Inch 9-Zone Super King Mattress, 27 cm
Price and rating as shown on Amazon when we collected them. Both change.
The dosleeps Super King Mattress is a 180 x 200 x 27 cm hybrid — gel memory foam laid over a 9-zone pocket sprung core, described as medium firm — sold at £259.99. It sits at number three in our super king guide and carries a rating of 4.4 out of 5 from 2,686 ratings at the time of writing.
The number that stands out here is one that behaves itself. The listing declares an item weight of 28.6 kg. Elsewhere in this same guide, hybrids of the same footprint declare "17 g" and "454 g", while the remaining ones sit between 17 kg and 45.2 kg — so 28.6 kg is the sort of figure that fits a mattress this size. The quieter oddity is the layer count: 12 layers inside a 27 cm mattress works out at roughly 2.25 cm per layer, and the same specification sheet lists an item depth of 28 cm against a stated thickness of 27 cm. Everything on this page is taken from the Amazon listing as it was written; none of it comes from testing we have carried out ourselves.
How those 2,686 ratings break down
An average hides its own shape. This is the spread behind the 4.4 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“This arrived at 8:12pm, I unboxed it, put it on the bed, cut the plastic and watched it expand, it took less than 10 minutes. I am now laying on it writing this and I feel like I'm floating on a cloud! What an amazing bargain, I am so comfortable after years of sleeping on a sprung mattress that had springs broken everywhere. I am looking forward to a really good nights sleep and I think I will finally get one! I cannot believe I bought this mattress for only £140! An absolute bargain!!!”

Lovely balance of soft comfort and firm support — great for my back and no sinking in. Quiet when moving, stays cool, and fits perfectly in my room. Excellent quality, great value, and I've slept so well since getting it — highly recommend”
