Frequently asked questions
Will a king topper fit a deep or pillow-top mattress?
Measure your mattress depth, including any pillow top, then check the skirt. The Freedom High Loft topper has a 50 cm fitted skirt, and the Easy Care, Sleep Tight and Reversible Coolmax toppers have a 40 cm skirt that stretches to fit mattresses up to 50 cm deep.
Should I choose a memory foam or fibre topper?
Choose memory foam if you want the topper to mould to your shape and ease pressure on hips and shoulders. Choose a fibre topper if you want a softer, plusher feel that you can put straight in the washing machine. If you sleep hot, look at the Cool Dry or Coolmax options instead.
Which king topper is best for allergies?
Look for a topper with anti-microbial protection that inhibits dust mites, mould and bacteria. The GreenSphere® Natural Anti Allergy topper has a plant-based treated cotton japara cover, and the Sleep Tight Anti Allergy topper has Bioguard™ anti-microbial protection. Both are machine washable, which helps keep allergens down.
