Goes like a dream
WHY NOT TRY OUR AWARD-WINNING SLEEP TECH?
Meet Simbatex® foam, which puts the ‘cool’ in our Cool Foam Topper. It keeps you cushioned, but its open structure also makes it a dream for hot sleepers – offering the same comfort as memory foam, only with over 5x more airflow . And for an even cooler feel, we’ve infused it with graphite to help move warmth away from your body.
The foam base of our Cool Foam Topper has a unique, contoured texture that responds to you for superb support. But it also does something else cool: the foam peaks form little pockets of space a similar shape to an egg, where fresh air can flow freely – helping you to stay cool and comfortable all night.
All Simba mattress toppers are made in the UK.

All the foam in our Cool Foam Topper is certified to CertiPUR® requirements, so it contains no heavy metals like mercury or lead.
The top cover is removable and washable, and washing instructions are included. Wash at 40°C on a reduced spin cycle. Do not use chlorine bleach. Do not tumble dry, iron or dry clean. The base fabric can also be cleaned with a soft, damp and clean cloth using small circular motions. Using a mattress protector could help extend the life of your mattress and topper.
Delivery is free as standard to most of the UK. In most cases, we deliver seven days a week when you pick a date at checkout. And if you choose to return your topper during your 200-night trial, returns are also free in most of the UK.
If you decide the Cool Foam Topper is not for you, just give us a call during the trial. We’ll arrange a free collection and refund the cost of your topper or any financing payments made (not including delivery charges). And don’t worry, we won’t ask you to get it back in the box.
Every Simba mattress topper comes with a 10-year guarantee. If it fails during that time, we’ll exchange it for a brand new one.
