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 & what's inside
- 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.

Who's it NOT for?
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.

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. Prices range from £769 to £1,280 depending on the size you choose, starting at £769.50.
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.
