At 27cm deep, the Hypnos Premier Ortho Superb pairs natural fillings, cotton and recycled Solotex™ fibre, with Hypnos's ReActive™ 6-turn pocket springs, which respond independently to you and your partner so movement on one side is less likely to disturb the other. It comes in ten sizes from small single up to emperor, plus EU sizes. It's a firm feel, so it suits back and front sleepers who want proper resistance, although lightweight side sleepers may find it a little unforgiving.

Why should you choose this mattress?
If you want a genuinely firm mattress rather than a medium dressed up as one, this is a strong candidate. The listing states it as firm, and the construction backs that up: 6-turn ReActive™ pocket springs designed to sense and spread pressure under each sleeper independently, which means support that adjusts to your shape without transferring movement across the bed. The fillings are cotton and breathable Solotex™ recycled fibre, which helps regulate temperature, useful if you tend to run warm. It carries a 10-year Hypnos guarantee as stated on the MattressNextDay listing, meets the BS7177: 2008 fire safety standard, and is made in the UK. Yes, the top end of the price range is a real spend, but the materials and build quality justify considering it.
Key features & layer details
Cotton sleep surface
A responsibly sourced cotton sleep surface that is naturally fire-resistant. It's the layer you'll actually feel, soft and breathable against the skin.
Cotton
A cotton filling that helps regulate body temperature, which means less overheating on warm nights. It also adds natural comfort and a touch of extra support.
Solotex™
A recycled fibre that is fully breathable, so air can move through the mattress rather than getting trapped. A quietly sustainable choice too.
ReActive™ 6-Turn Pocket Springs
Each spring has six turns and works independently, sensing the support you and your partner need and spreading downward pressure smoothly. In practice, that means consistent spinal support and less partner disturbance.

Best suited for?
Back sleepers
The firm feel and 6-turn pocket springs give proper resistance under the torso, so your body stays level rather than sinking in.
Front sleepers
A genuinely firm surface over independent pocket springs gives the resistance that keeps your hips from dropping too far into the mattress.
Couples
ReActive pocket springs respond independently to each person, which means movement on one side is less likely to disturb the other.
Warm sleepers
Cotton and breathable Solotex recycled fibre help regulate temperature and let air move through, so you are less likely to overheat on warm nights.
Eco-conscious buyers
Responsibly sourced cotton and recycled Solotex fibre make up the natural fillings, giving a more sustainable build that is also made in the UK.
This is a firm mattress, so lightweight side sleepers may find it presses on shoulders and hips rather than cushioning them. If you prefer a soft, sink-in feel, or the contouring hug of memory foam, look elsewhere. Budget shoppers should note the larger sizes are a real spend.
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 Hypnos Premier Ortho Superb mattress firm?
Yes. It's listed as firm, and the ReActive™ 6-turn pocket springs are built for total spinal and body support. That makes it a good fit for back and front sleepers who want a supportive, resistant feel, though lighter side sleepers may find it slightly too firm.
How deep is the Hypnos Premier Ortho Superb mattress?
It's 27cm deep. Standard fitted sheets should cope with that comfortably, though it's a substantial mattress, so factor in the weight if you'll be turning or moving it yourself.
Does the Hypnos Premier Ortho Superb come with a guarantee?
The MattressNextDay listing states a 10-year Hypnos guarantee. There's no sleep trial mentioned on that listing, so check the returns terms with your chosen retailer before you buy.
What sizes does the Hypnos Premier Ortho Superb come in?
Ten sizes: UK small single, single, small double, double, king, super king and emperor, plus EU single, double and king.
Is the Hypnos Premier Ortho Superb good for hot sleepers?
It should help. The cotton fillings regulate body temperature and the Solotex™ recycled fibre layer is fully breathable, which means heat can escape rather than building up around you overnight. It's a sprung, natural-fibre build rather than foam, which generally sleeps cooler.
