Is a Sofa Bed Suitable for Sleeping on Every Night?

You can sleep on a sofa bed every night – but only if it was built for it, and this is exactly where the market splits into two categories. For occasional guests, furniture retailers consistently agree that a simple pull-out or fold-out sofa with a foldable foam mattress is enough. If you sleep on the sofa permanently, though, the same specialist retail guides say you need a model with a proper, ideally adjustable slatted base and a separate mattress in the right firmness level. The basic rule from upholstered-furniture retail practice sums it up: the more often the bed function is used, the higher-quality the construction should be. Important context: there is no standard or reliable study on how suitable sofa beds are for permanent sleeping. All the figures that follow in this article are rules of thumb from retail practice – valuable as guidance, but not available as a standard. Knowing these figures still lets you make an informed judgement rather than guess, because the constructional differences between a guest solution and a permanent sleeping place can be clearly named.

You recognise a sofa bed for everyday sleeping by its substructure, not its cover: it needs a proper slatted base, a separate mattress and adequate dimensions. The following guideline figures come from furniture and upholstery retail guides (market observation, as of August 2026) – they are rules of thumb from sales practice, not standard values. But they agree across several retailers and so work well as a checklist before buying.

That fold-out sofas almost always contain foam is a matter of construction logic, not a quality shortfall. If the mattress is folded up and stowed under the seat, steel springs would bend at the fold and lying comfort would be gone – cold foam, by contrast, survives daily folding undamaged. That's how one upholstery guide explains it, and the consequence holds across the industry: wherever folding happens, foam is the technically right choice. That applies to us too – in our innerspring-focused range, we carry pure foam mattresses practically only where the mechanism demands it: in pull-out sofas. Innersprings in sofa beds do exist, though. Specialist retail guides describe pocket-spring mattresses for sofa beds with several hundred individually stitched steel springs that offer high point elasticity and suit every sleeping position. A Danish sofa-bed specialist states that it builds comfort systems from foam core to pocket spring with spring heights of 6 to 20 cm – some of which the manufacturer explicitly declares suitable for everyday sleeping. So the real deciding factor is the mechanism: if it folds the mattress, foam belongs inside. If it pulls out instead of folding, that restriction falls away – full-quality mattresses of any construction then become possible.

The most elegant guest solution is therefore not a folding mechanism but the pull-out principle – consistently applied in the transformable beds and sofa beds from Flou, one of our range's brands. Flou runs its own product category for this, with models such as Duetto, Diletto or Céline. According to the manufacturer, the Duetto combines a sofa, a chaise longue and a single or double bed in the footprint of a single bed: the first bed is permanently ready for sleeping, and beneath it sits a pull-out bed that a gas-piston mechanism lifts gently to the height of the first bed; rubberised steel blocks then let the two be joined firmly into a double bed. The base is a fixed slatted frame, and according to the retailer, each bed comes with a mattress in the 85 × 190 cm format as standard. What matters is: nothing here gets folded – the mattresses stay flat on their base and are therefore not subject to the foam logic of folding mechanisms. To be fair, it should be said: Flou designs the Duetto as a full single bed with a pull-out guest bed, not as a tested permanent double sleeping place. If you think of the principle more as a sofa, you'll find it in the Diletto (design by Pinuccio Borgonovo, 2025): raise the backrests, remove the seat cushion – and the sleep-ready bed on an adjustable slatted base is done; the version with the higher seat conceals a second pull-out bed beneath the base, according to the manufacturer.

If you sleep on a sofa bed permanently, every night, the honest answer is: you need a bed – even though we value both. A sofa bed solves a space problem, and no bed can do that: disappear during the day, be ready in the evening. A specialised sleep system, in turn, solves the opposite task with means that fit into no transformation mechanism. To put the scale in perspective: according to the manufacturer, DUXIANA builds a continuous spring system of high-tensile Swedish steel wire into the DUX bed – more than a mile of wire and up to 4,180 interconnected springs in a king-size format that dynamically adapt to movement. Constructions like that need structural height and a shape that never has to transform – precisely what a sofa bed forgoes by design. For a transparent sense of the investment: a full-quality bed starts with us at our box-spring own brand NUVOSETTE from CHF 3'900, DUXIANA from CHF 5'300. If you're unsure where your situation falls – guest room, studio, transitional solution or everyday sleeping place – bring the question to Nüschelerstrasse 30, five minutes' walk from Zurich Main Station. You can try lying down without an appointment (Mon–Fri 10:00–19:00, Sat 10:00–18:00), and we'll tell you honestly if a sofa bed is the better answer for your case than a bed – or the other way round.
