Award-winning British brand Simba Sleep launches all-new mattress topper, and the timing couldn't be better

British sleeper brand Simba has just released what they're calling their "easiest, most accessible way" to add their latest technology to your sleep setup. Enter, the Cool Foam Mattress Topper.

Starting at just £149, you'll get access to the brand's innovative cooling technology, medium-firm feel cushioning, better air flow, and more. The launch arrives hot on the heels of World Sleep Day (March 13, 2026) — a global awareness event organised by the World Sleep Society to promote healthy sleep – and ahead of the official start of Spring in the UK (March 20) where sleepers can expect overnight temperatures to begin to creep up.

If you've been looking for an opportunity to upgrade to a better night's sleep, now is the ideal time.

Be one of the first to buy the cool foam mattress topper from Simba

You can upgrade your sleep setup with the Simba Cool Foam Mattress Topper. Its specialised Simbatex foam is built to deliver over five times the airflow of traditional memory foam, helping you stay cool through the night. Plus, its responsive peaked base encourages constant ventilation, while the soft knitted cover is removable for easy washing. Prices start from £149 for the Single and go up to £299 for the Super King

Plus, if you're not ready to fully splash out on a new mattress, a new topper could be a better alternative.

With one of the best mattress****toppersfitted to your bed, you can enjoy extra comfort and support. Given that it's a removable layer, you can remove it and take it with you during a staycation in the campervan, for example.

Think of it as a "comfort upgrade kit" for your bed — it can make a too-firm mattress softer, a too-soft mattress more supportive, or add features like cooling or pressure relief. It can also act as a versatile addition to a guest bedroom if you're hosting those who have specific support needs.

What makes Simba's newest topper notably special is its built-in foam layer. The award-winning brand has packed its Simbatex material with graphite, which helps pull heat away from your body while you sleep. The open-cell structure means air flows through more than five times better than traditional memory foam – which is a great feature if you're someone who overheats at night.

It also comes with 6.5cm of cushioning with a medium-firm feel, so it adds proper support without making your bed feel wobbly. Underneath the cooling layer sits on a contoured foam base with an egg-crate texture that keeps air circulating throughout the night.

Simba has designed the new topper with flexibility in mind, too. It's lightweight enough to move around easily, making it perfect for student flats, spare bedrooms, family visits, or even temporary living situations between properties.
