The Hypnos Orthos Support 6's springs respond individually to your weight, which means support that follows your shape rather than pushing back as one flat surface, while the cotton gives a breathable, natural sleeping surface. It's a genuinely firm feel, so it suits back and front sleepers who want to lie on their mattress rather than sink into it. It comes in sizes from small single up to super king. Not cheap, but Hypnos has a reputation for traditional build quality and this sits at the more accessible end of their range.

Why should you choose this mattress?
Choose the Orthos Support 6 if firm support is your priority. The ReActive 6-turn pocket springs move independently, which means less partner disturbance and support that adjusts to heavier and lighter areas of your body. Four layers of cotton above the springs help with temperature regulation, useful if you're a warm sleeper, since natural fibres wick moisture better than synthetic foams. If you buy through Mattressman, they list a 60-night trial and free next day delivery, though these are the retailer's own offers rather than Hypnos terms, so check whichever shop you use. Heavier sleepers and anyone who has found softer mattresses leave their lower back unsupported are likely to get on well with this one.
Key features & layer details
Cotton comfort layers
Four layers of cotton sit at the top of the mattress. Cotton is breathable and wicks moisture, which means a cooler, drier feel through the night than synthetic fillings tend to give.
ReActive 6-turn pocket springs
The support core uses Hypnos's ReActive 6-turn pocket springs, each one working independently. That means the mattress contours to your body and limits motion transfer across the bed.

Best suited for?
Back sleepers
The genuinely firm feel keeps you lying on top of the mattress rather than sinking in, which suits anyone who likes a flat, supported surface.
Front sleepers
Firm tension and individually responding springs help stop the middle of the body dropping too far, so you stay on top of the surface.
Heavier sleepers
The ReActive 6-turn pocket springs work independently and adjust to heavier and lighter areas of your body, giving firm support that follows your shape.
Warm sleepers
Four layers of cotton sit above the springs, and because natural fibres wick moisture, the surface should feel cooler and drier through the night.
Couples
Each pocket spring moves independently, which limits motion transfer across the bed, and sizes up to super king leave plenty of room for two.
This is a properly firm mattress, so lightweight side sleepers may find it too unyielding at the shoulder and hip, leading to pressure points. If you like a plush, cradling feel, or you're used to memory foam that moulds around you, this traditional pocket sprung build will feel quite different and probably 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 Hypnos Orthos Support 6 firm or medium?
It's firm. Both Hypnos and retailer listings describe it as a firm mattress, so expect a supportive, stable surface with limited sink-in. It suits back and front sleepers best, while lighter side sleepers may find it a little too solid at the shoulder.
What sizes does the Hypnos Orthos Support 6 come in?
It's available in six UK sizes: small single, single, small double, double, king and super king.
Does the Hypnos Orthos Support 6 come with a trial?
Mattressman lists a 60-night sleep trial with free next day delivery on this mattress, but these are the retailer's own offers rather than a Hypnos guarantee. If you're buying elsewhere, check that retailer's trial and returns terms before you order, as they can differ from shop to shop.
What is the Hypnos Orthos Support 6 made of?
It combines four layers of cotton over a core of ReActive 6-turn pocket springs. The cotton provides a breathable sleeping surface, while the individually moving springs give firm, responsive support and help reduce motion transfer between partners.
