Hypnos Orthos Support 7 Firm Mattress
The Hypnos Orthos Support 7 Firm is a pocket spring mattress built around Hypnos's ReActive 7-turn pocket springs, which flex individually so the mattress can follow the shape of your body rather than pushing back as one flat surface.

As the name suggests, the Hypnos Orthos Support 7 Firm is a firm mattress, so it suits people who want a supportive, stable feel with less sink. It comes in five UK sizes, from Single through to Super King. It sits at the pricier end, but Hypnos is a long-established British maker and the spring system is the brand's own design rather than an off-the-shelf unit.

Why should you choose this mattress?
Choose this mattress if you sleep best on a firm surface: back sleepers and heavier sleepers tend to get on well with this level of support, as it keeps the spine level rather than letting the hips dip. The ReActive 7-turn pocket springs respond independently, which means less motion transfer if you share a bed and more even support across your body. If you're buying through Mattressman, the listing includes free next day delivery, with a 0-1 day handling time and 1-3 days in transit, plus a 60-night trial, which gives you a proper stretch of sleep to judge it rather than a quick lie-down in a showroom. Those terms are the retailer's own, so check them wherever you buy.
Key features & layer details
British wool top layer
Two layers of British wool from Red Tractor-assured farms form the breathable top of the mattress. That helps air move through the surface, so it should feel less stuffy as you sleep.
Cotton layer
Two layers of responsibly sourced cotton sit inside the wool layers. They keep you cool and dry, which is helpful if you tend to warm up overnight.
eOlus recycled fibre comfort pad
An adaptive comfort pad made from eOlus recycled fibre sits above the springs. It adds a little cushioning between you and the firm spring core, though the overall feel stays firm.
ReActive 7-turn pocket spring core
The core is Hypnos's ReActive 7-turn pocket spring system, which gives targeted support. The springs work independently, so you get firm, even support and less movement carried across the bed to a partner.
Cotton layer
A second layer of responsibly sourced cotton sits beneath the springs. It mirrors the cotton above, so the mattress stays cool and dry from both sides.
British wool bottom layer
A breathable British wool layer forms the base. Because the mattress is flippable, you can turn it over to spread wear, and the wool underneath keeps the same airy feel.

Best suited for?
Back sleepers
The firm feel keeps the spine level rather than letting the hips dip, which gives a stable, supported feel when lying face up.
Heavier sleepers
Firm tension and independently responding ReActive 7-turn pocket springs give solid support with less sink, so heavier bodies stay held up evenly across the mattress.
Couples
Because the pocket springs respond independently, there is less motion transfer across the bed, so one person's movement is less likely to disturb the other.
Combination sleepers
A firm surface with less sink makes it easier to shift position through the night, and the 60-night trial gives plenty of time to check it suits.
If you're a lightweight side sleeper, a firm mattress like this may feel a little unforgiving at the shoulder and hip, and a medium tension would likely suit you better. It's also a meaningful spend, so if your budget sits well under the starting price you'll find more choice elsewhere.
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
How firm is the Hypnos Orthos Support 7 mattress?
It's rated firm in the retailer listing. In practice that means a supportive surface with minimal sink, which tends to suit back sleepers and those who prefer to lie on top of a mattress rather than settle into it.
What springs does the Hypnos Orthos Support 7 Firm use?
It uses Hypnos's ReActive 7-turn pocket springs. Each spring sits in its own fabric pocket and moves independently, which means the mattress contours to your body and limits the ripple of movement across the bed when a partner shifts position.
How much does the Hypnos Orthos Support 7 Firm cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It's available in UK Single, Small Double, Double, King and Super King.
Does the Hypnos Orthos Support 7 come with a trial period?
Mattressman lists a 60-night trial on this mattress. That trial is the retailer's own offer rather than a Hypnos guarantee, so if you buy elsewhere the terms may differ. Always confirm the trial and returns policy with the specific retailer before ordering.
How quickly can the Hypnos Orthos Support 7 be delivered?
Mattressman offers free next day delivery on this mattress, with a handling time of 0 to 1 day and transit of 1 to 3 days. These are the retailer's delivery terms, so timings may vary if you buy through a different shop.
