Guest Room, Day Bed and Truckle

In short
A guest-room pack is a thin mattress, a place to store it, and sheets that match the open size. A day bed is a Single that looks like a sofa by day. A truckle, or trundle, rolls a second mattress from below. Sofa beds sit in other guides. This page is the spare-room kit — not a ranking.

What is the guest-room pack?
A guest-room pack is three things: a mattress the frame will close on, a place to store spare bedding, and sheets that match the open size. Shops sell sofa beds as the whole story. Mechanism pages already exist. This page is the spare-room kit.
A day bed is usually a Single that sits against a wall and looks like a sofa by day. A truckle or trundle is a low second bed that rolls out from below. Two thin Singles can sleep two guests. They need a clear floor when open.

What mattress goes on a day bed or truckle?
Most UK day beds take 90 × 190 cm. Some guest decks, including extra IKEA lines, use 90 × 200 cm. IKEA UK’s size guide also lists 80 × 200 cm. That guide was checked on 28 August 2026. The frame centimetres win. A 135 cm Double will not sit in a Single cavity.
Depth is the other limit. The truckle drawer or the day-bed lip has a maximum. A thick pillow-top will not close. Occasional reflex foam or a slim foam is common. That is a trade-off. It is not a quality rank and it is not medical advice.
| Item | Usual guest reading | Check before you buy |
|---|---|---|
| Day-bed plan | 90 × 190 cm | Frame sticker, not the word Single |
| Truckle plan | Often a second 90 × 190 cm | Drawer length and width |
| Extra-long guest | 90 × 200 cm | Sheets must be the long cut |
| Depth | Thin enough to close | Maker’s maximum centimetres |
| Feel | Occasional, not nightly | How many nights, not a slogan |
The National Bed Federation allows about 20 mm making spread. That note was checked on 28 August 2026. Twenty millimetres will not turn a Single into a Small Double.
What sheets and storage does a guest room need?
Match plan size and shallow pocket. A deep King fitted sheet will swim on a thin Single. See UK fitted sheet sizes and mattress depth.
Keep a labelled spare set: fitted sheet, duvet, two pillows, pillowcases. Store them in the same place every time. A day bed with drawers can hold the kit. An ottoman or under-bed boxes can too. Do not crush a spare spring mattress in the same drawer as the truckle.
| Kit piece | Why it fails if you guess |
|---|---|
| Fitted sheet | Wrong plan, or a pocket meant for a 30 cm hotel mattress |
| Duvet | A King duvet on a Single hangs and trips |
| Pillows | Guest heads still need loft — see how to choose a pillow |
| Protector | Sweat on a spare mattress is hard to air in a hurry |
Air a spare mattress before guests arrive. A sealed spare in a damp room can mould. See damp and mould under a mattress and how to store a mattress.
What floor space does a truckle need?
Measure the day bed closed. Then measure the rectangle beside it where the truckle will sit. You need about a Single width of clear floor, plus a little to walk. See how to measure a bedroom.
A truckle that opens into a door swing or a radiator is a failed guest night. Castors need a flat floor. Thick carpet can stop the drawer.
Two guests on two thin Singles is not the same as a zip-and-link Super King. There is a gap and a height step. Tell guests before they arrive.

Frequently asked questions
What is a truckle bed in the UK?
A truckle, or trundle, is a low second bed that rolls out from under a day bed or a higher Single. It usually takes a thin mattress. You need clear floor beside the main bed when it is open.
What size mattress does a UK day bed take?
Most UK day beds take a Single plan — 90 × 190 cm. Some guest decks use 90 × 200 cm. Confirm the frame centimetres. A UK Double will not sit in a Single day-bed cavity.
Why are guest mattresses thinner?
The drawer or the day-bed cavity has a depth limit. A thick pocket sprung unit will not close. Occasional comfort is the trade-off for daytime furniture.
What sheets do I need for a guest day bed?
Match the plan size and the shallow depth. A deep King sheet will swim on a thin Single. Keep a labelled spare set in the same store as the spare pillows.
Where do these facts come from?
BedGuide is desk research. The numbers and rules on this page were checked against the official or primary sources below. We name the check date. We do not invent a figure when a source is missing.
- IKEA UK mattress size guide — Lists UK sizes and extra 80 × 200 and 90 × 200 guest lines. Mixing those plans with a 90 × 190 day bed is a common sheet miss. Checked 2026-08-28.
- National Bed Federation — regulations and standards — UK plan sizes and a ±20 mm making spread. A truckle still needs the centimetres the frame states. Checked 2026-08-28.
