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.

- Room to sleep on different schedules: With 75cm each, one of you can get up hours before the other without a scramble across a shared middle, and the AeroSync Visco layer absorbs the movement too.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than a UK double, which matters if one of you is approaching six foot and tired of feet meeting the footboard.
- Cooling that scales with sharing: Two people generate more heat than one, so the graphite-infused foam and breathable mesh cover matter more in a shared UK king than they would in a single.
- Space for the dog: If a pet on the bed is part of the routine, the 15cm of width over a UK double is often the difference between comfortable and cramped.
- A firm, stable surface across the full width: The 7-zone support base runs edge to edge, so neither sleeper drifts into a dip, and the firm feel keeps back and stomach sleepers aligned.
This size suits you if...
You share the bed every night and want more personal space than a UK double allows, especially if you and your partner keep different hours or one of you is tall enough to appreciate the 200cm length. It also suits hot-sleeping couples: foam's usual heat problem is worse with two people, and this mattress is built specifically to counter it.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest as a minimum for a UK king, or you sleep alone and don't need the width. The Mysa Breeze comes in UK king only, so a smaller room means a different mattress rather than a smaller size.

Is the Mysa Breeze available in any size other than UK king?
No. The Mysa Breeze is currently sold in a UK king only, at 150 x 200cm. If your bed frame or room needs a UK double, small double or super king, you'll need to look at a different mattress. For a couple upgrading from a double frame, though, this single-size range is exactly the size most people are shopping for.
Is a UK king big enough for a couple and a dog?
Usually, yes. The UK king gives two people 75cm each, which is 7.5cm more per person than a UK double, and that margin is often what a medium-sized dog quietly claims. The AeroSync Visco layer also dampens movement, so a pet resettling at 3am is less likely to travel through the mattress to you.
Will the Mysa Breeze UK king fit my bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king, which leaves space to walk round the bed and open drawers. Measure carefully in a new build master bedroom: they often look generous empty but tighten quickly once fitted wardrobes go in. If you're under that minimum, a king will dominate the room.
Is the UK king long enough for someone over six foot?
At 200cm, the UK king is 10cm longer than a UK double, and for anyone around the six foot mark that extra length is often the real reason to upgrade. One caveat specific to this mattress: at 20cm deep it sits a little lower than taller foam models, so pair it with a base you find easy to get in and out of.
Where can I buy the Mysa Breeze in a UK king?
Stock and pricing move around, so the most reliable answer is the live comparison table on this page, which is updated as retailers change their prices. It's worth checking before you commit, because memory foam mattresses at this end of the market are discounted fairly often and the gap between full price and offer price can be meaningful.
