Care Instructions

Every effort was taken whilst making your new mattress to ensure that it will provide you with excellent comfort and support for years to come. However, there are a number of steps you can take, during use, to make certain you get the most from your new purchase

  • Once unwrapped, leave the mattress uncovered for a few hours to let it breathe - some mattresses may release an odour but this will dissipate once the mattress has been well aired.
  • Where using a bedstead with slats with this mattress, please ensure that the slats are no more than 7.5cm apart. Please note that varying levels of comfort may be produced depending on which slats or support system is used on your bedstead.
  • We recommend the use of a mattress protector with this item.

It is recommended to rotate and turn your mattress once a week during the first 3 months and once every 3 months thereafter (please take care when moving your mattress, they are heavy): 

  1. Rotate the mattress through 90 degrees
  2. Turn the mattress over
  3. Rotate the mattress through a further 90 degrees
  • Air your mattress regularly; this should be done on a weekly basis
  • Do not roll or bend your mattress
  • Clean your mattress once a month with a soft brush; do not use a vacuum cleaner. Treat spills or stains immediately with a dry cloth or paper towel
  • Please do not stand or allow children to jump on your mattress
