What Is a Wall Bed? The Complete UK Buying Guide
A wall bed — also known as a Murphy bed, fold-down bed or pull-down bed — is a bed that folds up vertically into a cabinet or recess when it's not in use, freeing up the floor space it would otherwise take up.
They've traditionally been associated with studio flats and New York apartments, but they've become a genuinely practical option for a much wider range of UK homes: box rooms, home offices that occasionally need to be a spare room, and any space where you want a proper bed without dedicating a whole room to it permanently.
This guide explains how wall beds work, what to look for before buying, and whether one is likely to suit your space.
How Does a Wall Bed Work?
A wall bed frame is hinged at one end and mounted either directly to the wall or inside a cabinet. When not in use, the frame — mattress, bedding and all — folds up and sits flush (or close to flush) against the wall. When you want to use it, you pull it down and it locks into a stable, floor-supported sleeping position.
The part that makes this practical rather than a two-person wrestling match is the lifting mechanism, which counterbalances the weight of the bed and mattress so it can be raised and lowered smoothly, usually with one hand. There are two common types:
- Spring mechanisms use a set of tensioned springs to balance the load. Because the number of springs can be adjusted to the exact weight involved, they tend to suit heavier mattresses and higher-spec setups well.
- Gas piston (pneumatic) mechanisms use one or more gas struts, similar to those on a car boot. They're generally smoother and quieter for lighter loads, though a piston that isn't correctly sized for the weight it's supporting can feel less controlled.
Either way, a well-made wall bed should be easy to operate and shouldn't require you to force it in either direction.
Wall Bed vs Murphy Bed vs Fold-Down Bed — Is There a Difference?
In everyday UK use, no — these terms are used interchangeably to describe the same basic idea. "Murphy bed" is technically a brand name that became so widely used it's now shorthand for the whole category, much like "hoover" for vacuum cleaners. "Wall bed" and "fold-down bed" are more generic descriptions of the same thing.
You may see some retailers draw a more specific distinction between a "Murphy bed" (traditionally metal-framed, spring-operated) and a "wall bed" (often wood-framed, sometimes with built-in shelving or a desk), but this isn't a consistent or official distinction — it varies by manufacturer.
What Sizes Do Wall Beds Come In?
Wall beds are generally available in the same mattress sizes as standard UK beds:
- Single (90 x 190cm) — suited to a single adult, a guest room, or a home office that occasionally sleeps one person.
- Small double (120 x 190cm) — a good middle ground where a single feels tight but a full double won't fit.
- Double (135 x 190cm) — for a couple, where the room and wall space allow.
- King (150 x 200cm) — less common, and worth double-checking the available wall width and floor clearance before committing.
The larger the bed, the more wall space and floor clearance the folding mechanism itself needs, so it's worth measuring both the bed's footprint when open and the space it needs to swing through as it folds — not just the size of the mattress. Our wall bed dimensions and space requirements guide walks through exactly how to measure your room before buying.
Can You Use Your Own Mattress?
Often, yes, but with one important caveat: wall bed mechanisms are rated to a maximum mattress depth (commonly around 20–25cm), and going over this can affect how smoothly — and safely — the bed opens and closes. Always check the manufacturer's maximum depth before buying a mattress, rather than assuming any standard mattress will fit.
It's also worth checking that a mattress is suitable for being stored vertically for long periods, since it will spend most of its life folded upright rather than lying flat. Some retailers sell mattresses specifically designed or approved for wall bed use.
How Much Space Does a Wall Bed Actually Save?
Because the entire bed — not just the mattress — lifts out of the way, a wall bed can reclaim roughly the same floor area as the bed itself: often somewhere in the region of 30-40 square feet for a double, depending on the model. That space can then be used for a desk, seating, storage, or simply an empty, walkable room during the day.
This is the core appeal for a home office that needs to become a guest room, a studio flat where the "bedroom" and "living room" are the same room, or a box room that's too small to permanently dedicate to a bed alone.
Wall-Mounted or Freestanding Cabinet?
Most wall beds are fixed either directly to the wall studs or bolted into a supporting cabinet or frame that's fixed to the wall. This matters for two practical reasons:
- Renting. If you're renting, wall mounting isn't always straightforward, and it's worth checking with your landlord before buying. Some systems are designed to be freestanding or more easily removable than others.
- Moving house. Most wall beds can be disassembled and reinstalled elsewhere, so buying one isn't necessarily a decision tied to your current property — but it's still more involved than moving a normal bed frame.
If a room is narrow rather than short on wall width, some wall bed systems can be mounted lengthways (horizontally) rather than the more typical vertical orientation, which can make them work in oddly-shaped rooms that wouldn't otherwise fit a bed comfortably.
Are Wall Beds Comfortable?
A well-made wall bed uses a genuine mattress on a proper supportive base, rather than the thin, ridged foam typical of a sofa bed or the give of an air mattress. Once it's down and made up, there's generally very little to distinguish sleeping on a wall bed from sleeping on a standard bed — which is one of its biggest advantages over other space-saving sleeping options.
How Long Do Wall Beds Last?
A well-built wall bed, used regularly in a normal domestic setting, should comfortably last a decade or more — the mechanism is generally the part that experiences the most wear, so it's worth checking what warranty is offered on the lifting mechanism specifically, not just the frame.
What Does a Wall Bed Cost?
Wall beds cost more than an equivalent sofa bed or air mattress, typically by a significant margin, because you're paying for the frame, the mattress-support base, and a mechanical lifting system rather than just upholstered seating. Prices vary widely depending on size, finish and whether a cabinet or desk unit is included, so it's worth comparing what's actually included — a bare mechanism and frame is a very different purchase to a complete, finished unit with cabinetry.
Who Is a Wall Bed Best For?
- Studio flats and small apartments, where the bedroom and living space are the same room.
- Home offices that need to double as a guest room without looking or feeling like one day-to-day.
- Box rooms that are too small to comfortably fit a bed and anything else.
- Anyone who regularly hosts guests but doesn't want to dedicate a room to it full-time.
If you rarely need the extra sleeping space, or you're in a short-term rental, a space-saving bed, sofa bed or air mattress may be a simpler and cheaper fit — our comparison guides below go through the trade-offs in detail.
Frequently Asked Questions
Is a wall bed as comfortable as a normal bed?
Yes, generally. A wall bed uses a full mattress on a supportive base, so once it's folded down there's very little difference to sleeping on a standard bed.
Can I fit my own mattress to a wall bed?
Usually, provided it's within the mechanism's maximum rated depth and suitable for long periods of vertical storage. Always check the manufacturer's specification before buying a mattress separately.
Do wall beds need to be fixed to the wall?
Most are fixed to the wall or wall studs for stability, so it's worth checking with your landlord before installing one in a rented property.
How much floor space does a wall bed save?
Roughly the footprint of the bed itself once it's folded away — often in the region of 30-40 square feet for a double bed, depending on the model.
Are wall beds expensive?
They typically cost more than a sofa bed or air mattress, since you're paying for a mechanical lifting system as well as the frame and mattress support, but many buyers find this worthwhile for the comfort and space saved.
