Layer Details
- Quilted Cover. The cover and fillings are stitched together to create a patterned comfort quilt layer. This gives the sleep surface a soft, slightly cushioned first impression before you reach the firmer support beneath.
- Advanced Comfort Foam. A breathable foam that gently contours to your body shape, which means personalised comfort and tension relief at the shoulders and hips. It acts as the buffer between you and the spring unit below.
- Open Coil Springs. Interlaced coils of high-tensile steel joined together in a lattice provide the core body support. Because the coils are connected, the whole surface works as one, giving that traditional, evenly firm feel.
Layer details from mattressnextday.co.uk product page, September 2026.
- Fits the smallest rooms: At 3ft wide it slots into box rooms, loft conversions and shared children's bedrooms; allow at least 2.1m x 2.8m of floor space.
- Supportive for growing sleepers: The interlaced open coil unit supports the whole surface evenly, which means firmer, orthopaedic-style support for children and teens as they grow.
- Softened first impression: A layer of Advanced Comfort Foam under the quilted cover contours gently, so lighter bodies aren't pressed straight onto firm springs.
- Practical for raised frames: At 24cm deep it's a fairly standard height, so it's worth measuring against a bunk or mid sleeper's guard rail before buying.
- Sensible guest room choice: A low-cost, medium firm single suits a spare room or study that only occasionally hosts guests, without tying up money in a bed rarely slept on.
This size suits you if...
You're buying for a child or teenager who needs even, firmer support at a low price, you're kitting out a guest room or a spare room that doubles as an office, or you're a solo adult in a compact bedroom, student room or first flat where a 90cm width is all the space allows.
Consider another size if...
You're an adult who sleeps alone but wants more room to stretch out. The UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

What are the dimensions of the Zante Ortho UK single mattress?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard one-person size in the UK, so it fits ordinary single bed frames, divans, bunks and mid sleepers, and standard single fitted sheets will fit without bunching.
Will the Zante Ortho single fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard bunk and mid sleeper frames. The mattress is 24cm deep, which is on the taller side for raised frames, so check your frame's maximum mattress depth and guard rail height before buying, particularly for a top bunk.
Is the Zante Ortho single a good mattress for a child's room?
It's a reasonable fit. The medium firm open coil support suits growing bodies, and the comfort foam layer softens the surface for lighter sleepers. At 90cm wide it leaves floor space for a desk, wardrobe and toy storage; we suggest allowing at least 2.1m x 2.8m of room.
Should I buy the Zante Ortho in a single or a small double?
For a child, teenager or occasional guest bed, the UK single is the practical choice. For an adult sleeping alone every night, the UK small double gives 30cm more width at the same length, provided your room offers at least the 2.4m x 2.8m we suggest for it.
