Can you sleep on a sofa bed every night?
Yes, if the mattress is built for it. The warnings you find online concern sofa beds with thin foam pads on metal frames. A sofa bed with a real full-length spring system is something else: a bed that happens to be a sofa. Here’s the difference, concretely.

Why do some warn against sleeping on a sofa bed?
Because most cheap sofa beds use 5–8 cm of foam over a foldable metal frame. After a few weeks you feel the frame through the foam, and your body lies in an arc. That is what “can hurt your back”, not the sofa bed as a category.
| System | How it works | Suited for |
|---|---|---|
| No-zag springs | Steel wave springs + high-resilience foam for even, soft support | Combined use: mostly sitting, regular sleeping |
| Pocket springs | Individual springs in pockets that follow your body | Regular sleeping: guest rooms for weeks, studio flats |
| 5-zone multi-pocket | Zoned firmness (softer at shoulders, firmer at hips) | Daily use as your main bed |
Four things that matter more than you think
1. A real mattress across the full lying surface. Bed widths run from 80 cm (sleeper chairs and daybeds) through 115–160 cm to CozyPad’s 208 cm wide surface, and length is 195–210 cm for most models; Norum goes furthest with up to 320 cm of lying surface, followed by Newilla Lounger at 300. Check the dimension drawing in both modes on the product page.
2. Bed height. 38–55 cm makes getting in and out easy. Low frames (under 30 cm) wear on you over time.
3. A fabric that takes daily use. Sleeping wears more than sitting; a removable cover (as on Circlus and CozyPad) is a plus, and the fabric should be abrasion-tested regardless.
4. Abrasion rating (Martindale). Our fabrics are tested to between 27,000 and 200,000 rubs. The furniture industry’s daily-use threshold is 20,000+.
Which model for sleeping every night?
Killian is built for it: 5-zone multi-pocket springs in 140 or 160 cm, the closest thing to a proper bed in the range. Neah (double springs) and Cubed (No-zag + duvet storage) are strong picks for frequent guest use and studio flats.
Unsure? Visit the showroom at Bygdøy allé and lie on them. Five minutes on your back beats five hours online.
In short
Sleep on the sofa bed every night if: the mattress has real full-length springs, the width is 140 cm+, and the fabric is abrasion-tested for daily use. Avoid it if: the sofa has a thin foam pad over a folding frame. That’s the whole difference.
Frequently asked questions
How thick should the mattress be?
Thickness matters less than real springs across the full surface: our pocket spring mattresses carry 6–12 cm spring layers depending on the model, and Killian’s 5-zone mattress (an 8 cm spring core with comfort layers) is built for sleeping every night. The layer build-up is listed on each product page.
Does folding leave marks in the mattress?
The spring systems are built for daily folding. It’s foam mattresses that develop permanent creases.
What does a sofa bed built for daily use cost?
Here, from 14,400 kr (Splitback with pocket springs) to 29,490 kr (Killian 160 with 5-zone).
