Description

  • Easy zip-off cover
  • state-of-the-art foam layers
  • pressure relief and body moulding support
  • Onethird® material recognised by NASA

OneThird Hybrid Luxe Mattress - OneThird provides unparalleled support and comfort. Ideally suited for foam enthusiasts, experience a truly wonderful sink-in sensation and feel refreshed and rejuvenated every morning. 

Easy zip-off cover

The OneThird is fitted with an easy-to-remove and machine-washable cover in order to maintain a fresh and hygienic sleep surface. Additionally, the OneThird doesn’t need to be flipped or rotated for further convenience. 

Supportive foam layers

The OneThird comprises state-of-the-art foam layers, allowing for fantastic comfort and support. At the mattress's core is a layer of block foam, a clever alternative to pocket springs that offers edge-to-edge support. The addition of this durable foam ensures superb longevity and complete peace of mind. Elsewhere, the Onethird® material provides unparalleled pressure relief and body moulding support. The material, comprised of billions of viscoelastic open cells, responds to pressure and paves the way for targeted support. In addition, the memory foam is designed to reduce excess movement throughout the night for a peaceful night’s sleep. In a testament to the quality of the Onethird® material, it’s recognised by NASA and certified by the Space Foundation. Finally, the quilted finish ensures a comfortable, flat sleeping surface. 

Is this mattress suitable for me?

As the name suggests, the Onethird® One Soft features a soft tension and is designed with side sleepers in mind. While sleeping in this position, you’ll benefit from cushioned hip and shoulder support. For peace of mind, any mattress purchased alongside a mattress protector is eligible for a 60-night sleep trial.
