Layer Details
Advanced Cortec Quad pocket springs
This is the main pocket spring system, described as award-winning. It gives the mattress its firm, supportive base, so you lie on top of the surface rather than sinking into it.
Micro spring layer
A layer of 2,500 high-density micro springs sits above the main system. It adds a finer level of cushioning, which helps ease pressure and takes some of the edge off the firm tension.

Key benefits
- Fits the smallest bedrooms: At 90cm wide it leaves room for a desk, wardrobe or toy storage in a child's room, and slots under the slope in a loft conversion.
- Firm support for growing sleepers: The firm tension gives children and teens a flat, supportive surface to lie on rather than sink into, which many parents prefer for developing backs.
- Pocket springs, quietly: Springs that move independently keep the surface stable and quiet, useful in a shared children's room where one restless sleeper can wake another.
- A 24cm depth to check against raised frames: Bunk beds and mid sleepers set maximum mattress depths for safety rail clearance, so measure your frame before assuming this 24cm mattress will suit.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child or teenager and want a firmer, more supportive surface than a budget foam single, or you're kitting out a spare room or study that doubles as guest space, or you're a single adult in a compact room, student flat or loft conversion where a 90cm footprint is the only one that works.
Consider another size if...
You're an adult who spreads out in the night, or you occasionally share the bed. The 90cm width is a genuine squeeze for two, so we'd recommend the UK small double instead: it's 30cm wider, the same length, and needs a room of at least 2.4m x 2.8m.

FAQ's
What room size do I need for the Pure Response Firm in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you the mattress footprint of 90 x 190cm plus enough clearance to walk round and open drawers. It's our own guidance rather than the brand's, and it makes the UK single an easy fit in box rooms, lofts and studies.
Is the Pure Response Firm single too firm for a child?
A firm tension is generally fine for children and teens, who tend to be light enough that the surface feels supportive rather than harsh. The exception is a lightweight side sleeper, who may feel pressure at the shoulder and hip. If your child sleeps mostly on their side, a softer tension is worth considering.
Will the 24cm depth work on a bunk or mid sleeper frame?
Possibly, but check first. Raised frames specify a maximum mattress depth so the safety rail still sits high enough above the sleeping surface. At 24cm this mattress is deeper than some bunk frames allow, so measure from the base to the rail top and compare against the frame maker's guidance before ordering.
Can two singles work instead of one bigger bed in a guest room?
Yes, and it's a flexible setup. Two UK singles at 90cm each suit guests who'd rather not share, and the firm pocket sprung feel here works well for occasional use because it holds its shape without a regular sleeper's break-in. Just allow walkway space between the two frames when you measure up.
How much narrower is the UK single than the UK small double?
The UK single is 30cm narrower than the UK small double, and the two are the same length at 190cm. That extra width matters for adults who move around in the night, which is why we'd steer a grown-up buying for themselves towards the UK small double where the room allows, at least 2.4m x 2.8m.
