The Thermopure 30 mattress offers unrivalled posture support, despite having no springs! What's the secret? It's all down 20cm thick layer of Kaytex support foam, topped off with another 10cm of heavenly gel-infused memory foam - so you get the best of both comfort and support as you rest up.

The high density Katex support foam prevents sagging and ensures that your body stays aligned and supported, while the memory foam allows for some pampering! Specially designed to mould to the contours of your body and relieve pressure, it has also been infused with gel to give it heat regulating properties – so you can rest easy at your natural body temperature.

All that advanced technology has been wrapped up in a stylish package using super stretch knit fabric and tencel; one touch of the plush, cozy finish and you won't be able to resist having a lie down. Better yet, it's breathable and cool too so you can enjoy a peaceful sleep with no distractions - except for your dreams, of course.

The mattress rests on a solid divan base, with the added option of integrated storage drawers to hide away all that bedroom clutter.

Thermopure 30cm | Super King | 6ft is rated 1.0 out of 5 by 3.
Rated 1 out of 5 by from Not good for Posture - get springs! Bought this just before my wife had our first child. I honestly don't know what we were thinking. We were told it was great for posture and firm. It's not. Both of us find it too soft and neither of us really feel rested after a nights sleep. Even worse - it doesn't fit a standard King size Divan Base. It's actually 155cm wide and not 150cmeeting. So it overhangs each side by 2.5cm or an inch. This just looks sloppy. Honestly, a huge regret. Especially at that price. Get a good spring mattress, cheaper and far superior. And it will probably fit the Base too!

Rated 1 out of 5 by from Not great! We decided to get this because my wife and I both have bad back and injury's. When we first got the mattress it was lovely and comfortable but after a year it started to sagAnd thankfully HN replaced it for us after an engineer saw it. Unless you are very light I wouldn't recommend it.

Rated 1 out of 5 by from Not good Bought it year ago. At the beginning it was really comfy and relief to sleep at. After year is just not comfy any more. The cooling system never really worked
