Mattress Trial: 200 Night Sleep Trial

We understand that choosing the perfect mattress can sometimes be overwhelming. That's why this mattress has a 200 night 'love it or exchange it' sleep trial. If you're not 100% satisfied, we'll exchange it. Click here to view the full mattress trial policy. 

  • Medium/Firm - Good for all sleeper types
  • Soft and Hygienic Cover - Allows for a fresh and luxurious sleep. 
  • Memory Foam - Pressure relieving memory foam cleverly moulds to every contour of your body, delivering you restful and supportive sleep right through until morning. It senses your body's weight and temperature and remembers it. Memory foam responds to the position and shape of your body and makes the necessary adjustments to meet your body's needs. 
  • Supporting Foam - Two added layers of supportive foam balances the softness of memory foam to keep you supported throughout the night, whilst relieving aches and pains. 
  • Individually wrapped pocket springs - Each spring works effortlessly to provide a more traditional, bouncier feel along with limiting the transfer of movement across the mattress. 
  • Super Stretch Cover - Stretching in all directions to support you throughout the night as your body moves. 
  • Easy Care - No need to turn, but regular rotation from head to toe will extend the mattress's life span. 
  • Rolled and Vacuum Packed - Easy to transport upstairs, through small stairways and loft spaces. Once in your room, the mattress can be unpacked in minutes, then wait just two hours and the mattress is ready to use.

  16. Q:How long does my mattress take to fully expand?
    A:Please unpack your mattress within 30 days of delivery. Once opened, it will begin expanding immediately and regain its shape within approximately 15 minutes.
