A zed bed is a folding guest bed that opens out into a Z shape, hence the name. It is usually a compact frame with a thin mattress that folds into three sections, then unfolds flat for sleeping and folds back up on castors for storage in a cupboard, under a stairs or against a wall. Most zed beds are single size, sit low to the ground and weigh little enough for one person to move.
The appeal is simple: a proper sleeping surface that takes up almost no space when it is not needed. For UK homes without a spare room, that is often the difference between being able to host someone overnight and not.
The frame is hinged in two places along its length. When folded, the mattress sections stack on top of each other and the whole unit stands upright, typically around 30cm to 40cm deep and roughly the width of a single bed. Castors on the base let you roll it into a cupboard. To open it, you roll it out, tip it forward and let the sections unfold flat, then the legs lock into position.
Most models use a metal mesh or sprung slat base beneath foam. The mattress is thinner than a standard one, usually between 8cm and 15cm, because it has to fold. That thickness is enough for occasional use but not intended as a permanent bed.
Best for genuinely occasional guests where storage space is tight and there is no permanent furniture to spare. Cheapest and lightest of the three, quickest to put away.
Similar in principle, though some fold in half rather than thirds and may carry a thicker mattress. A folding bed with a deeper mattress will be more comfortable but heavier and bulkier when stored.
The better option if guests stay several nights or if the room needs to work as a living space day to day. A sofa bed earns its footprint twice, functioning as seating and as a bed. If you host more than a few times a year, browse our modern sofa beds UK sale range, where the mattress depth and frame support are closer to a proper bed.
Where a room is already used as a bedroom, a storage bed solves a different problem: keeping bedding and spare pillows within the bed itself rather than in a cupboard.
Flats and terraces rarely have a dedicated guest room. A zed bed suits a home office that occasionally doubles as a spare room, a box room used mainly for storage, or a living room where a bed can be set up after everyone has gone to bed and cleared before breakfast.
They also work well for children’s sleepovers, since the low height is easy for younger children and the light frame can be moved by a teenager without help. In a child’s room, a zed bed stored in a wardrobe alongside modern childrens beds UK keeps the floor clear on ordinary days.
Student accommodation, holiday lets and annexes are other common settings, where the ability to add a sleeping space without adding permanent furniture has obvious value.
Most zed beds are single, around 190cm long and 90cm wide when open. A few are small double at 120cm wide, though these become heavy to fold. Folded height is usually between 90cm and 110cm, and folded depth between 25cm and 45cm.
Before buying, measure three things: the storage space when folded, the floor area when open, and the route between the two. A zed bed that fits the cupboard but will not pass through the doorway on its castors is a common frustration. Check the height of any door frame if the folded unit stands tall.
Leave at least 50cm of clear space on one side when the bed is open so a guest can get in and out. In tight rooms, plan to move a chair or side table temporarily rather than trying to squeeze the bed into a gap.
A zed bed will not match a full mattress, and it is fairer to everyone to accept that. What you can do is improve it noticeably with small measures. A mattress topper of 5cm or so transforms the surface. Proper fitted sheets rather than throws stop the sections separating in the night. A decent pillow matters more than usual, since the mattress gives less support.
Check the folding line placement too. Some designs put a hinge roughly under the hips, which is where most people notice it. Models with the sections joined by a continuous mattress cover feel more even.
For guests who visit regularly, or for anyone with back issues, it is worth stepping up to a sofa bed or a proper spare mattress instead. Our mattresses UK sale selection includes rolled options that can be stored upright in a cupboard as an alternative approach.
Steel frames last longer than lightweight aluminium under repeated folding. Look at the weld quality at the hinge points, since that is where stress concentrates. A stated maximum user weight is a useful indicator of build quality.
Sprung slats give more comfort than a flat mesh, and mesh gives better airflow than a solid panel. Airflow matters for a bed that gets folded away while the mattress is still warm.
Two locking castors are better than four free spinning ones, particularly on wooden floors. Test that the leg locks engage firmly, as a frame that can partially collapse is the main safety concern with folding beds.
Try opening and closing it if you can. A well designed zed bed should open with one hand on the frame and no lifting of the mattress. Anything that requires two people is not doing its job.
A fabric cover keeps dust off the mattress between uses. If one is not supplied, a large cotton dust sheet works.
Air the mattress for an hour before folding it away, especially after a night’s use. Store it upright rather than flat so the foam is not compressed in one place for months. Once or twice a year, wipe the frame, check the hinge bolts are tight and a spot of light oil on stiff joints keeps the action smooth.
Keep the bedding separately in a bag or a modern blanket box UK rather than folded inside the bed, where it holds moisture against the foam.
Ask how often you host and for how long. One or two nights a few times a year, with nowhere to keep a permanent bed, is exactly the case a zed bed answers. Weekly guests, longer stays, or a room that could accommodate dual purpose furniture point towards a sofa bed or a storage bed instead.
It is also worth thinking about who will be sleeping on it. Children and younger adults tend to be untroubled by a thinner mattress. Older guests, or anyone with mobility issues, will find the low height harder to get up from.
We stock guest sleeping solutions across all of these categories at Furniture in Fashion, so it is worth comparing a zed bed against a compact sofa bed before deciding. Free delivery to most UK mainland postcodes applies across the range.
Most zed beds are opened in a room that does another job for the rest of the year, whether that is a home office, a dining room or a nursery that has not yet been outgrown. A little planning makes the difference between a guest sleeping well and a guest spending the night wedged between a desk leg and a radiator. Open the bed once before your visitors arrive and work out which wall it can sit against with the door still able to swing freely.
Leave a clear path from the bed to the door so nobody has to feel their way past furniture in the dark, and put a small table or a stool within arm’s reach for a glass of water and a phone. A single plug socket within reach matters more than people expect, because a guest with no way of charging a phone overnight will remember that more clearly than the mattress. If the room has no bedside lighting, a plug in lamp or a clip on reading light solves the problem for a few pounds.
A folded zed bed is roughly the depth of a slim bookcase, which means it fits behind a door, inside a double wardrobe or along the side wall of a landing cupboard. What it does not do well is share a cupboard with anything that is needed weekly, because moving it in and out repeatedly is when castors get bent and covers get torn. Give it a home you can reach without unpacking the rest of the cupboard.
Where cupboard space simply is not available, consider whether furniture with built in storage is a better long term answer. A bedroom that already holds an ottoman or drawer base bed from our modern beds UK sale range frees up the cupboard capacity a zed bed needs, and keeps spare bedding in the same room as the guest who will use it.
Because the frame folds into a Z shape when stored, with the mattress in three stacked sections.
For most people, yes, particularly with a mattress topper added. They are not intended for nightly long term use.
Usually single, around 190cm by 90cm when open. Small double versions exist but are heavier to handle.
Rarely, because the folded unit is too tall. They are designed to be stored upright in a cupboard, alcove or against a wall.
Most state a maximum between 90kg and 120kg. Always check the specification rather than assuming.
For frequent or longer stays, yes, because the mattress is thicker and the frame more supportive. For rare use with no spare floor space, a zed bed is the more sensible answer.
