The Mysa Breeze combines a BeFree® 3D mesh cover, which the brand states is 40% more breathable than standard knits of the same weight, with graphite-infused open-cell foam designed to draw heat and moisture away from you. At 20cm deep it's slimmer than some foam mattresses, so it feels a little closer to the base than a taller model would. It's made in Manchester, hypoallergenic and vegan-friendly, and comes with a 120-night trial and a 10-year guarantee. It comes in UK King only and sits at the affordable end of the memory foam market.

Why should you choose this mattress?
If you're a hot sleeper who has been put off memory foam before, the Breeze is built for you: graphite-infused cooling foam and a breathable mesh cover work together to reduce the heat build-up foam is known for. The AeroSync Visco layer minimises motion transfer, which means you're less likely to feel a partner turning over in the night. A 7-zone support base keeps your spine aligned from shoulders to hips. The firm feel suits back and stomach sleepers particularly well. Yes, it's only 20cm deep, but the layered construction packs cooling, pressure relief and zoned support into that depth, and the price reflects good value rather than corners cut.
Key features & layer details
BeFree® 3D mesh cover
A removable mesh cover the brand states is 40% more breathable than standard knits of the same weight. That means better airflow across the sleep surface and less trapped heat.
AeroSpheric HR-GX® cooling foam
Open-cell foam infused with graphite spheres, which helps regulate your core temperature and wick away moisture. This is the layer doing most of the cooling work.
AeroSync Visco foam
A viscoelastic layer that absorbs movement, which means a partner shifting position is far less likely to wake you. Couples will feel this benefit most.
AeroSync HR-GX® multi-zoned comfort foam
This layer responds to the natural curves of your body across multiple pressure zones. In practice, that means less pressure on shoulders and hips and full-body tension relief.
7-zone support base foam
A targeted support core that reinforces key areas of the body. It promotes consistent spinal alignment from shoulders to hips through the night.

Best suited for?
Warm sleepers
Graphite-infused open-cell foam and a breathable mesh cover work together to draw heat and moisture away, so the bed should feel less stuffy overnight.
Back sleepers
The firm feel and 7-zone support base keep your spine aligned from shoulders to hips, which suits lying flat on your back.
Front sleepers
A firm surface stops your hips sinking too far, which helps keep your body level when you sleep on your stomach.
Couples
The AeroSync Visco layer absorbs movement, which means you are less likely to feel your partner turning over during the night.
Allergy sufferers
Hypoallergenic construction and a removable mesh cover make this a sensible pick if you want a cleaner, more considered sleep surface.
This is a firm mattress, so lightweight side sleepers may find it doesn't allow enough sink at the shoulder and hip. If you prefer a soft, cradling feel, or want a taller, more substantial mattress than 20cm, look elsewhere. It's also currently sold in UK King only, which rules out other bed sizes.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Mysa Breeze mattress firm or soft?
Mysa describes the Breeze as firm. Owner reviews suggest it offers good firmness without feeling too hard, which suits back and stomach sleepers well, although lightweight side sleepers may find it a little too firm for comfortable pressure relief.
Does the Mysa Breeze sleep hot?
It's designed specifically not to. The BeFree® 3D mesh cover is 40% more breathable than standard knits of the same weight, according to Mysa, and the graphite-infused AeroSpheric foam is built to regulate temperature and wick moisture. If you're a hot sleeper, this is one of the mattress's main selling points.
Does the Mysa Breeze come with a trial and guarantee?
Yes. Mysa offers a 120-night trial, so you can sleep on it at home before committing, plus a 10-year guarantee against manufacturing faults.
How deep is the Mysa Breeze mattress?
It's 20cm deep, which is slimmer than some foam mattresses. That depth still contains five layers, including cooling foam, a motion-isolating layer and a 7-zone support base, but if you prefer a taller mattress this may not suit you.
How much does the Mysa Breeze cost and what sizes are available?
It comes in UK King only, and the price table on this page shows the current price. Delivery is free across the UK as standard, with next-day delivery available when you order before 12pm.
