About this product
Boost the comfort of your existing mattress with this breathable topper that keeps air circulating around your body for a restful night's sleep. It's designed with a dual-layer construction and air mesh sides that allow airflow to move freely between the layers, so you'll stay comfortable through every season. The 5cm filling provides softness and support that helps refresh tired mattresses, while the elasticated corner straps secure it firmly in place without shifting. It's non-allergenic, which makes it suitable for sensitive sleepers who need a practical bedding solution.
The elasticated corners fit quickly over your mattress, even on deeper styles. It's machine washable at 40C and tumble dryer safe, so keeping it clean is straightforward. The breathable design works to regulate temperature year-round, while the deep filling adds a layer of comfort without the expense of replacing your mattress. Whether you're looking to soften a firm bed or extend the life of an older one, this topper delivers reliable comfort and freshness.

Customers Say
Comfortable and soft mattress topper improves bed comfort and sleep quality, though some find it less thick and supportive than expected. Good value for money and breathable material praised.

Poor quality
Not very thick and therefore flattens and doesn't give the support it claims to give

Super cushiony
Extremely soft and cushiony. Put on a coil spring bed and this topper has made if feel much for softer and my child loves going to bed and feels extra cosy now. Washed and used low temp on tumble drier. When it was sunny air dried it outside.

VFM comfort
Great, comfortable mattress topper. Has vastly improved the comfort of the bed at a fraction of the cost of a new mattress.

Glad we bought it
This was bought for my mum’s hard bed mattress as she was unable to sleep. She found it very comfortable and breathable. Value for money.

Good quality
The quality is great but it had a factory stain which obviously is disappointing, hence the 3 star rating. Other than that great product.

Not as much couchioning as i was expecting.
I bought this for extra comfort on a new bed. Unfortunately i was a bit disappointed as it didn't have as much cushioning as i expected. It appears breathable & fits well, but i am not happy.

5cm mattress topper a little thin
I bought this for a slightly firm mattress I recently swapped to and it is a lot softer. I was concerned that the 8cm version would be too thick for the fitted sheets but the stated 5cm is really no more than 2cm so wished I had gone thicker

Cosy
Bought to bridge the gap between two small single mattresses on my daughter’s pull out bed. She finds the topper really comfortable and warm. It doesn’t really give additional support as it not firm enough, but it’s cosy and my daughter loves it, so very happy with the purchase.
Strawbs, 45 - 54
Love it
So comfortable!!!!!!
