Sleep hot? Maybe you’re looking at the wrong part of your bed
A thinner blanket, a loose sheet, an open window: you’ve probably tried all sorts of things to beat those sweltering nights. But what if the heat isn’t in your duvet at all, but in your mattress?
Check your mattress
The whole bed, not just the blanket
Why replacing your duvet often doesn’t make all the difference
Heat gets trapped in your mattress, not just your duvet
Most mattresses are made from dense memory foam that stores and retains your body heat. A thinner blanket won’t change that, because heat comes just as much from below as from above.
Exactly why a new summer blanket sometimes still isn’t enough.
Gel-infused foam draws heat away instead of trapping it
The Ella Mattress Topper features open-cell foam infused with gel to actively dissipate heat instead of trapping it. This works differently from a thinner blanket, which simply provides less insulation.
The AirMesh underside lets air circulate beneath your mattress
There’s usually no airflow between your mattress and bed base, so heat has nowhere to go. The AirMesh layer on our topper restores air circulation, keeping your bed fresh not just on top, but underneath too.

That clammy feeling often comes not just from your duvet, but also from moisture trapped in your mattress. The topper’s bamboo cover absorbs and wicks away moisture, neutralizes odors, and is antibacterial.
You don’t have to get rid of your duvet
The topper works with the bedding you already have. Just place it on your mattress as usual, and tackle the problem at its source instead of continuing to patch things up with increasingly thinner blankets.
Try it for 100 days in your own bed
Five minutes of trying it out tells you nothing about a warm summer night three weeks later. That’s why you get 100 days to sleep on the topper in your own bed. If you’re not happy with it, let us know through the returns portal.

Frequently asked questions
I already have a cooling blanket, so why should I check my mattress too?
A cooling blanket only solves what’s happening above you. You’ll still feel heat trapped in your mattress, especially on your back and underneath you. Using both together gives the best results.
Does a mattress topper really help with night sweats?
A topper with gel-infused foam and AirMesh can noticeably reduce heat buildup in your mattress. Heavy night sweats can also have a physical cause; if so, discuss it with your doctor.
Which topper is right for me?
All toppers have the same breathable base, so your choice mainly depends on thickness and firmness. The 7 cm Medium-Soft is our bestseller for side and stomach sleepers, the Firm 7 cm provides more pushback for back sleepers, and the 10 cm Ergo Topper offers the most comfort.
Can I wash the cover?
Yes, the bamboo cover has a zipper and can simply be machine-washed.
How does the sleep trial work?
You can try the topper on your own bed for 100 nights. If you’re not satisfied, let us know through the returns portal and follow our return policy.
