Enhance your night's rest with the wonderful OneThird® Hybrid Luxe Mattress - Medium. Engineered with the latest technology, this premium all-foam mattress offers unparalleled comfort and support. 

Premium foam composition

One of the mattress’s many standout features, the OneThird® Hybrid Luxe Mattress - Medium conforms to the body's contours, relieving pressure and providing targeted support all night long. The visco-elastic cells respond precisely to pressure, ensuring optimum comfort. Moreover, the memory foam also minimises motion transfer, promoting a peaceful night's sleep; this state-of-the-art memory foam, recognised by NASA and certified by the Space Foundation, is a testament to the mattress's quality and innovation. Elsewhere, a layer of block foam provides the foundations for greater stability and durability; this layer allows for edge-to-edge support, meaning you can utilise the entire mattress surface. The block layer is also recognised for its seamless ability to distribute weight evenly throughout the night.  Finally, the quilted finish ensures a comfortable, flat sleeping surface. 

Easy zip-off cover

The OneThird is fitted with an easy-to-remove cover to ensure a fresh and hygienic sleep surface. This cover is machine washable, meaning maintaining a clean and fresh mattress has never been easier. For further convenience, the OneThird doesn't need to be flipped or rotated. 

Is this mattress suitable for me?

The OneThird mattress features a medium tension and is designed with side sleepers in mind. The soft mattress surface is able to cushion the hip and shoulder while sleeping in this position. Please note that the One mattress is single-sided and doesn't need to be rotated or flipped. For peace of mind, any mattress purchased alongside a mattress protector is eligible for a 60-night sleep trial. 

Disclaimer: Each mattress spec is reflected in the description and details on the page, Please note however that the outside cover can sometimes be a bit different to the images reflecting on the season and time of year
