Per Weiss and the Innovation Living Design Language

Nearly every sofa bed in this range traces back to one designer. Per Weiss has been part of Innovation Living since 1989 and has led the brand’s design direction for most of that time — which means the catalog isn’t a collection of unrelated products so much as one design sensibility applied across four decades and a lot of changing ideas about how people live.

The throughline: function first, styling second

The company’s own framing is direct: the goal is furniture that “makes a difference in everyday life,” with design built around solving the actual problem of limited space rather than styling a sofa that happens to fold out. That ordering — function first — shows up consistently across the range, even as the aesthetic language has shifted over the years.

It’s visible in small details as much as big ones. Carnell’s design stores the seat and back cushions during conversion, solving a genuinely annoying nightly problem rather than just adding another feature. Osvald and Cone are built around bedding storage as the founding idea, not an add-on. Zeal’s independently adjustable wings exist because a compact daybed needs to do more than one job. None of these are styling decisions — they’re responses to how someone actually lives with the piece day to day.

A design timeline across the catalog

Looking at when different collections were designed shows how the range has evolved:

2008 — Cassius and Supremax. The Deluxe Excess Lounger family, built around chrome legs and a classic, tailored European silhouette. Comparatively traditional in profile, and still in the catalog because the design has held up.

2013 — Zeal. A compact daybed defined by mid-century styling — dark wood stiletto legs, a clean, spare frame — built around independently adjustable side wings rather than a full sofa-to-bed conversion.

2015 — Osvald, designed with Emil Højfeldt. A softly rounded, minimalist profile built specifically to solve storage in small apartments.

2023 — Cone, Neah, and Newilla, a cluster of releases representing the current generation. This is where Double Spring and No-zag & Pocket Spring — the two newest comfort systems in the range — first appear, alongside a more contemporary, softer overall silhouette than the 2008-era pieces.

2024 — Carnell. The most recent addition, and the only reversible-mattress design in the catalog.

That’s not an exhaustive design history, but it’s enough to see the pattern: the earlier pieces (Cassius, Supremax) favor a classic, structured sofa silhouette, while the newer generation (Neah, Vilander, Newilla, Carnell) leans toward softer profiles and more sophisticated mattress engineering. Neither is “better” — they represent different points in an ongoing design conversation, and the range keeps both because both still suit different rooms and preferences.

What “Danish design” means here, concretely

The phrase gets used loosely in furniture marketing generally. In this range, it points to a few specific, checkable things rather than a vague aesthetic claim:

Materials that show, rather than hide, their construction. Ran’s curved walnut wood arms, the wood tray accessory available for Newilla and Vilander, and the solid wood frames under Newilla and Cubed are all cases where the material stays visible and legible rather than being upholstered over.

Restraint over ornamentation. Osvald’s “softly rounded and minimalistic” brief, or Cubed’s description as reflecting “a timeless balance between craftsmanship and functionality,” both point to the same instinct: reduce the piece to what it needs to be, rather than adding detail for its own sake.

Problem-solving as the design brief. The company describes its own mission as designing sofas that “Expand Your Living Space” — which is a functional claim, not a stylistic one. Compact living in cities is the actual design problem this whole range exists to answer.

Styling around it

If you’re furnishing around one of these pieces, the design language gives you a fairly clear direction to lean into rather than fight:

  • Let materials be visible. Pair a wood-legged or wood-armed model with other furniture that shows real wood grain rather than surrounding it entirely in upholstery.
  • Keep the palette restrained. The pieces themselves are already doing quiet, considered work — busy patterns elsewhere in the room compete with that rather than complement it.
  • Prioritize function in what you add around it. A storage ottoman or a wood tray fits this design language better than a purely decorative piece, because the collections themselves were built around solving a problem, not just looking good.

Frequently asked questions

Who designs Innovation Living’s sofa beds? Per Weiss, who has been with the company since 1989 and has led design across most of the current catalog. Osvald was co-designed with Emil Højfeldt.

What does “Danish design” mean for a sofa bed specifically? In this range, it points to visible, legible materials like solid wood frames and arms, a restrained aesthetic without heavy ornamentation, and a design process that starts from a functional problem — usually limited space — rather than styling alone.

Are the older collections (like Cassius, from 2008) worse than the newer ones? Not necessarily worse — different. Earlier designs favor a more classic, structured silhouette; recent releases like Neah, Vilander, and Newilla use newer comfort systems and a softer profile. Both are still in the catalog because both suit different preferences.

What’s the newest design in the range? Carnell, from 2024, is the most recent, and the only collection built around a reversible Dual Memory mattress.
