Onethird support
The unique PostureTech Core Support spring system has been researched by medical professionals. Unlike traditional pocket springs, Onethird PostureTech Support springs get firmer under pressure. Providing tailored support for your whole body. Each spring can move to give responsive support focussing on the heaviest parts of your body. These springs are twice tempered which is the process of unique heat treatment that strengthens and enhances the spring structure. Adding incredible durablity and stability to the mattress.
Ortho packed
Zoned into three sections, the middle third of the mattress contains Onethird PowerPack technology. Denser springs within this zone provide added lumbar support for orthopaedic relief.
On the edge
Sleep or sit right on the edge of your new mattress, with no sag or roll off. The super sturdy reinforced sprung edge prevents that feeling of having a wall at the edge of your mattress. Instead, it cradles your weight for ultimate pressure relief.
A fresh look
The ultra comfortable mattress top is hand tufted for the perfect firmer feel. Finished with a striking modern damask cover for that plush touch. The mesh vented sides allow for enhanced breathability, helping your mattress stay clean and cool for longer.
Made to last
This mattress is double sided and can be flipped every few months to maximise comfort and longevity. The four vertical handles along the mattress edge make it easy to lift and manoeuvre with two people.
100% Recyclable
All Onethird Ortho mattresses are 100% recyclable at the end of their use, with no components going to landfill. Buy in confidence with the 5 Year manufacturer Guarantee.
