The Mysa Glacier has a medium-firm feel, which means it suits most sleepers, although those who prefer a soft, sink-in surface may find it a little too supportive. At 25cm deep with a removable, machine-washable mesh cover, it's a practical choice as well as a cooling one. Mysa backs it with a 120-night trial and a 10-year guarantee, and it's made in Manchester. If you're a hot sleeper on a mid-range budget, this one deserves a close look.

Why should you choose this mattress?
Cooling is where this mattress puts its effort. The BeFree 3D mesh cover is designed for airflow, the graphite-infused foam beneath it draws heat away from your body, and a layer of breathable microcoils keeps air moving through the middle of the mattress. Underneath, the 5-zone pocket springs adapt independently to your movements, which means support goes where your body needs it and your spine stays in a more neutral position. It's hypoallergenic, vegan-friendly and GoodHomes Approved, and the cover washes at 40°C. Delivery is free across the UK, with next-day available if you order before 12pm. For a hybrid with so much going on inside, the starting price is fair rather than a stretch.
Key features & layer details
BeFree® 3D mesh knit cover
A removable knit cover that Mysa says is 40% more breathable than standard knits of the same weight, which means less heat builds up around you overnight. It's machine-washable at 40°C, a small feature that makes a real difference over years of use.
AeroSpheric HR-GX® graphite-infused foam
Open-cell foam infused with graphite spheres, claimed to deliver twice the cooling of regular graphite foam. It moulds to your body shape while wicking away excess moisture, so you get contouring without the warmth memory foam is known for.
Microcoil® ergonomic support layer
Small individual open coils that conform closely to your body for targeted pressure relief. They're also highly breathable, adding another route for air to move through the mattress.
AeroSync HR-GX® multi-zoned comfort foam
High-resilience polyurethane foam that contours across multiple pressure zones, which means cushioning where your hips and shoulders press down hardest. Mysa describes the effect as weightless-feeling.
5-zone pocket spring system
Individually pocketed springs that respond independently to your movements, giving orthopaedic-style support to key areas of your body. This is the layer doing most of the work to keep your spine aligned.
Firm foam base layer
A high-density foam foundation beneath the springs. It gives the whole mattress a stable base to work from.

Best suited for?
Warm sleepers
The mesh cover, graphite-infused foam and breathable microcoils all move heat and air away from your body, so you are less likely to overheat overnight.
Allergy sufferers
Hypoallergenic materials and a removable cover that washes at 40°C make it easier to keep the sleeping surface fresh and clean over the years.
Combination sleepers
The medium-firm feel and 5-zone pocket springs respond independently to movement, which means support follows you as you change position through the night.
Back sleepers
Zoned pocket springs and a stable foam base help keep your spine in a more neutral position, giving the support back sleepers tend to want.
Eco-conscious buyers
Being vegan-friendly and made in Manchester gives shoppers who care about how their bed is made a couple of clear points in its favour.
Sizes are the main limitation: it comes in UK Small Double and Double only, so it's not an option if you need a single, king or super king. If you love a soft, enveloping feel, you may also find the medium-firm surface slightly too solid.
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 Glacier hybrid good for hot sleepers?
Cooling is its main design focus. The graphite-infused foam is claimed to deliver twice the cooling of regular graphite foam, the mesh cover is 40% more breathable than standard knits of the same weight, and the microcoil layer keeps air moving through the core.
How firm is the Mysa Glacier mattress?
Mysa describes it as medium-firm. That suits most back and side sleepers, although lightweight sleepers who like a plush surface may find it a touch firm at first.
Does the Mysa Glacier come with a trial and guarantee?
Yes. Mysa offers a 120-night trial and a 10-year guarantee, so you have a full season or more to decide at home before you're committed.
What sizes does the Mysa Glacier come in?
Just two at present: UK Small Double and UK Double. If you need a single or a king, you'll need to look elsewhere in Mysa's range or beyond.
Can you wash the Mysa Glacier mattress cover?
Yes, the BeFree 3D mesh cover is removable and machine-washable at 40°C, which makes it easier to keep fresh than most fixed covers.
