The All Seasons Mattress Topper utilises Outlast® technology in its fitted sheet. With proactive heat and moisture management, this advanced material developed for NASA stores and releases heat for optimum thermal comfort. Outlast® technology is non wicking, which manages moisture by reacting to your sweat and pulling it away from the skin. This moisture managing material is extremely hygienic and adapts to your skin’s microclimate so you sleep better, longer and feel more refreshed in the morning.

The fitted sheet is cleverly designed to fit over the topper or both the topper and mattress. Quick and easy to apply and is easily removed for washing.

Outlast® Technology

Helps regulate your skin’s microclimate. As the skin gets hot, the heat is absorbed and as it cools, that heat is released leaving you just the right temperature all night long.

Removeable Cover

Features a fully removable, washable cover/fitted sheet. Simply take off from the topper and wash at 30°C.


Ideal for allergy-sufferers, the memory foam core provides excellent protection against allergens, mould and dust mites. A great choice for a clean and healthy sleeping environment.
