Layer Details
- Cover. A breathable Belgian damask fabric cover. It lets air move through the surface, which helps keep the sleeping surface fresher.
- Comfort Fillings. Resilient polyester comfort fillings with layers of soft white fibres. These sit between you and the springs, which means a softer initial feel that helps alleviate pressure points.
- Eco Comfort Fibres™. Breathable, sustainable fibres that are 100% recyclable. They've been scientifically proven to keep you cooler while you sleep, a helpful layer if you run warm at night.
- Support System. 1400 pocket springs, each mounted in its own separate fabric pocket. They work completely independently, which means support that follows your shape and less disturbance when a partner moves.

- Leaves floor space free: At 3ft wide the UK single fits a room from 2.1m x 2.8m, which means a desk, drawers or toy storage can still share the space.
- Check raised frames first: The mattress is 24.5cm deep, so before ordering for a bunk, cabin or mid sleeper, compare that against the frame's stated maximum mattress depth.
- Firm support for one: With 1400 pocket springs under a single sleeper, the whole surface responds to one body, giving growing teens and back sleepers an even, orthopaedic-style feel.
- Reassurance for allergy-prone children: The Allergy UK Seal of Approval and hypoallergenic fillings are a comfort if you're furnishing a room for a child who reacts to dust.
- Pairs easily in a twin guest room: Two UK singles side by side let guests who aren't a couple sleep separately, each on their own sprung surface.
- Fits a sloped loft ceiling: The narrow footprint tucks under the low side of a loft conversion, keeping the taller part of the room clear for standing and dressing.
This size suits you if...
You're furnishing a child's or teenager's room where the bed has to share space with storage and a desk, you're a single adult who likes a firm surface and has a compact bedroom or student room, or you're setting up a spare room or study that sometimes hosts a guest.
Consider another size if...
You share a bed, or you want room to spread out at night. We'd recommend the UK small double instead: it is 30cm wider, and we suggest at least 2.4m x 2.8m.

Will the Venice Ortho 1400 UK single fit a bunk bed or mid sleeper?
It measures 90 x 190cm, the standard UK single footprint most raised frames are built around. The catch is depth: at 24.5cm, it may sit higher than some bunk and cabin beds allow for their guard rails. Check the frame maker's maximum mattress depth before you buy.
Is a UK single Venice Ortho 1400 big enough for an adult?
For one adult of average height, usually yes, as it gives 90cm of width and 190cm of length. If you're tall and your feet reach the end, the UK king is 10cm longer, although we suggest at least 2.7m x 2.9m of floor space for the UK king.
How much room do I need for a Venice Ortho 1400 in a UK single?
We suggest allowing at least 2.1m x 2.8m. That leaves space to walk around the bed and open drawers, which matters in a box room or a child's bedroom where furniture competes for every bit of floor.
Venice Ortho 1400 UK single or UK small double for one person?
The UK single is 30cm narrower than the UK small double, and the two are the same length. If you sprawl or have the space, the UK small double is more comfortable, but we suggest at least 2.4m x 2.8m for the UK small double.
Will a UK single Venice Ortho 1400 fit in a loft conversion?
Its 3ft x 6ft 3in footprint is narrow enough to run along the low side of a sloping ceiling. Measure the headroom where the sleeper will sit up, since the mattress adds 24.5cm of height on top of whatever frame you use.
