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.

- Real stretching room for one: At 120cm wide, this size gives a solo sleeper generous space to spread out, which the evenly firm open coil support carries edge to edge.
- Fits rooms a double cannot: The UK small double slots into box rooms, studio flats and loft conversions where a bigger frame would block a door or leave no walking space.
- Sensible for a growing teenager: A teenager who has outgrown a single gets adult-sized sleeping space without giving up desk or wardrobe room, and the medium firm feel supports a changing frame.
- A practical guest room choice: Occasional visiting couples can share it comfortably for a few nights, and the low price suits a bed that isn't slept on every night.
- Easy bedding at 4ft: The small double is a standard UK size, so 4ft fitted sheets and frames are widely stocked, and a normal double duvet works well on top.
This size suits you if...
You sleep alone and want noticeably more room than a UK single without stepping up to a full double, your bedroom, loft conversion or studio can spare only around 2.4m x 2.8m of floor space, or you're furnishing a guest room or rental where couples stay occasionally and a low price matters more than a long guarantee.
Consider another size if...
You share the bed every night, since 120cm is tight for two and the interlaced coils pass movement across the surface. We'd recommend the UK double instead: 15cm wider, 67.5cm each, and it needs a room of at least 2.6m x 2.8m.

Is a small double Zante Ortho big enough for one adult?
Comfortably, yes. At 120 x 190cm it gives a solo sleeper 30cm more width than a UK single at the same length, so you can spread out or change position freely. The interlaced open coil unit supports the whole surface evenly, which means the extra width feels usable right to the edges rather than soft at the sides.
Can a couple sleep on the Zante Ortho small double every night?
We wouldn't suggest it for nightly sharing. The width is snug for two adults, and open coil springs transfer movement more than pocket springs, so you'll feel a partner turning over. For occasional guest room stays it's fine. For every night together, the UK double is 15cm wider and gives 67.5cm each.
What room size do I need for the Zante Ortho in a UK small double?
We suggest a room of at least 2.4m x 2.8m. That leaves enough space to walk around the bed and open drawers, which matters in the box rooms and loft conversions this size is often bought for. The mattress itself is 120 x 190cm, so measure with the frame's extra bulk in mind too.
Is the small double a good choice for a teenager's room?
It's a sensible upgrade once a single feels cramped. The 30cm of extra width over a UK single suits a growing teenager, while the length stays the same at 190cm, so it takes up no more of the room front to back. The medium firm feel gives firmer support than many cheaper foam options at a similar price.
Should I size up from the small double to the UK double or UK king?
If two of you will sleep on it nightly, yes. The UK double is 15cm wider and needs at least 2.6m x 2.8m of room; the UK king is 30cm wider and 10cm longer, with 75cm each, and needs at least 2.7m x 2.9m. If you sleep alone in a compact room, the small double is the better fit.
