More Info


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.
