Product Details

Our King Size Essentials 5cm Memory Foam Mattress Topper is a cost-effective solution if your existing mattress is too firm or uncomfortable.

Designed to offer an excellent compromise between bedtime luxury and value for money, this cheap mattress topper comes without a cover and slots straight underneath your bottom sheet.

This 5cm layer of medium density memory foam (45kg/m3) gives you the luxurious feel and comfort of memory foam for a very reasonable price. Memory foam also provides relief for your joints and pressure points, reduces tossing and turning, and encourages healthy blood circulation.

This king size mattress topper is manufactured in our Yorkshire factory, and is delivered compressed and rolled for easy manoeuvring.

If your saggy old mattress is truly beyond saving or improving, the only way to get a restful night’s sleep is by replacing it. At Memory Foam Warehouse, we have a whole range of great value memory foam mattresses for you to choose from.
