Innovation Living builds its sofa beds around six distinct comfort systems. Each one layers springs, foam, and fiber differently, and each produces a different feel when you sit and when you sleep. Knowing which system a collection uses tells you more about how it will perform than any photograph can — so this guide maps all six to the collections we carry.
The six systems at a glance
| System | Collections | Frame | Spring layers |
|---|---|---|---|
| Double Spring | Neah, Vilander | Metal | Pocket spring over no-zag spring |
| No-zag & Pocket Spring | Newilla | Solid wood | Pocket spring over no-zag spring, plus hyper soft foam |
| No-zag Spring | Cubed | Solid wood | No-zag spring only |
| Pocket Spring Dual | Osvald, Cone, Walis | Rigid metal | Pocket spring with an added foam casing |
| Pocket Spring | Recast Plus, Unfurl, Zeal | Rigid metal | Pocket spring only |
| Excess Pocket Spring | Cassius, Supremax, Ran | Rigid metal | Taller pocket spring coils |
The full technical breakdown for each system, including layer specifications, lives on our comfort systems page.
What the layers actually do
Every system is a stack. The names change but the components repeat, so it helps to know what each one contributes before comparing systems.
Pocket springs are individual coils, each sewn into its own fabric pocket. Because they aren’t wired together, they compress independently — pressure lands on the springs directly under you rather than rippling across the whole surface. That’s what gives a sofa bed the feel of a proper innerspring mattress instead of a folded pad.
No-zag springs run beneath the seat as a suspension layer rather than a mattress layer. They’re broad and elastic, and their job is to stop you from bottoming out. Where pocket springs contour, no-zag springs absorb. They also leave air space, which helps the whole assembly breathe.
High resilient foam encases the springs. It’s the layer that determines how soft the surface feels on first contact while still returning to shape after years of use. Hyper soft foam, where it appears, is an additional layer above that — a deliberate softening step, not a substitute.
Fiberfill sits near the top and adds plushness. Fibertex is a stabilizing layer that holds the mattress shape and keeps the foam from migrating. Metal mesh, in the systems that use it, spreads load across the frame.
The frame is the last variable, and the one buyers most often overlook. Innovation Living uses both durable metal frames and solid wood frames depending on the collection, and the choice changes how the piece behaves. More on that below.
Double Spring: Neah and Vilander
Double Spring is the newest of the six and the one Innovation Living leads with. It combines a no-zag suspension system with a pocket spring core, both encased in high resilient OEKO-TEX certified foam, over a durable metal frame.
The reason for stacking two spring types is that sitting and sleeping ask opposite things of a surface. Sitting concentrates your weight into a small area — the no-zag layer absorbs that and prevents the hard landing you get on cheaper sleepers. Sleeping distributes weight across the whole body, and that’s where the pocket spring core takes over, contouring the way an innerspring mattress does.
Both Neah and Vilander use this system, and Innovation Living positions both as ready for daily use rather than occasional guest duty. Neah is the more compact of the two and the only family we carry in three sizes with three arm styles. Vilander is the broader three-seater, with cushion, roll, and wide arm options.
Layer specification: fabric cover, fiberfill, high resilient foam, pocket spring, no-zag spring, durable metal frame.
No-zag & Pocket Spring: the Newilla family
Newilla uses the same two spring types as Double Spring but assembles them differently, and the differences are worth understanding because these two systems are easy to confuse.
Newilla adds a hyper soft foam layer above the high resilient foam, and it’s built on a solid wood frame rather than a metal one. The extra foam layer produces a noticeably softer top than Double Spring delivers. The no-zag layer adds elasticity and lets the mattress breathe, which matters if you run warm.
This system covers the whole Newilla family — the sofa bed, the lounger, and the lounger chair — so you can build a matched set with consistent feel across pieces. Newilla is also the collection with removable, washable covers, which puts it in a different category for households with kids or pets.
Layer specification: fabric, fibertex, fiberfill, hyper soft foam, high resilient foam, pocket spring, fibertex, no-zag spring, solid wood frame.
No-zag Spring: Cubed
Cubed uses no-zag springs alone, without a pocket spring core, on a solid wood frame. The thick layer of high resilient foam above the springs does most of the comfort work.
This produces an even, soft surface across the whole seat with no variation between zones — well suited to a sofa that spends most of its life being sat on, and to a compact footprint where the mattress has to fold into a smaller volume. Cubed is the most compact model in the range and folds out into the room rather than requiring wall clearance, which is why it turns up so often in studio apartments.
If your priority is a piece that’s excellent as a sofa and genuinely comfortable when guests stay over, this system does that. If you’re planning to sleep on it every night, look at the pocket spring systems instead.
Layer specification: fabric, fiberfill, high resilient foam, fibertex, no-zag spring, solid wood frame.
Pocket Spring Dual: Osvald, Cone, and Walis
Pocket Spring Dual shares the general composition of the standard Pocket Spring system, with one addition: an extra layer of hyper soft foam that gives these models a distinctly softer feel. Innovation Living specifically recommends this system for everyday sleeping — the only one of the six carrying that recommendation on the strength of the mattress alone.
The pocket springs here measure 3.9 inches, sitting in a foam casing over fibertex, metal mesh, and a rigid metal frame. The result is soft seating comfort without the mattress giving up support overnight.
Osvald and Cone are related designs, both built around generous storage beneath the seat. Walis applies the same comfort system in a daybed format.
Layer specification: fabric, fiberfill, high resilient foam, fiberfill, foam casing, pocket spring 3.9″, fibertex, metal mesh, rigid metal frame.
Pocket Spring: Recast Plus, Unfurl, and Zeal
The standard Pocket Spring system is the most direct of the six. Individual pocketed coils apply pressure independently, so support is distributed rather than uniform, and the high resilient foam casing keeps the assembly breathable while providing a soft top.
The springs measure 4 inches, over fibertex, metal mesh, and a rigid metal frame. Without the extra hyper soft layer that Pocket Spring Dual adds, the feel is firmer and more supportive — which some people prefer outright, particularly for sitting.
Recast Plus offers this system in a streamlined sleeper available armless or with slim arms. Unfurl pairs it with three back positions, so the same piece sits, lounges, or lies flat. Zeal applies it to a daybed with independently adjustable ends.
Layer specification: fabric, fiberfill, high resilient foam, pocket spring 4″, fibertex, metal mesh, rigid metal frame.
Excess Pocket Spring: the Deluxe Excess collections
Excess Pocket Spring uses taller coils than the standard system. Higher coils compress further before reaching their limit, which produces a softer sofa feel and gives each spring more room to absorb pressure — a more forgiving surface for sleeping.
This is the system on the Deluxe Excess models: Cassius, Supremax, and Ran. All three are generously sized queen sleepers, and the taller spring suits that scale — a larger sleeping surface benefits from more travel in the springs, not less.
Layer specification: fabric, fiberfill, high resilient foam, taller pocket spring, fibertex, metal mesh, rigid metal frame.
Metal frame or solid wood frame: what changes
Four of the six systems use a metal frame; two use solid wood. This isn’t a quality ranking — it’s a design decision tied to how each mechanism works.
Metal frames carry load through a rigid structure and handle repeated folding well, which matters for mechanisms that convert frequently. Double Spring, Pocket Spring, Pocket Spring Dual, and Excess Pocket Spring all use metal.
Solid wood frames appear on Newilla and Cubed. Wood flexes slightly under load in a way rigid metal doesn’t, and in Newilla’s case it pairs with the hyper soft foam layer to produce that collection’s softer character.
The practical takeaway: if you’re comparing Neah against Newilla — the comparison we’re asked about most, since both combine no-zag and pocket springs — the frame is the real difference. Neah is metal-framed and firmer through the seat. Newilla is wood-framed with an extra soft foam layer above the springs. They are not the same construction with different upholstery.
Which system suits how you’ll use it
| How you’ll use it | Look at | Why |
|---|---|---|
| Everyday sleeping, this is your bed | Pocket Spring Dual, Double Spring | Dual is specifically recommended for everyday sleeping; Double Spring is built for daily use |
| Primary sofa, guests a few times a year | No-zag Spring, Pocket Spring | Excellent seating, comfortable overnight, no compromise on the sofa side |
| Softest possible surface | No-zag & Pocket Spring, Excess Pocket Spring | Hyper soft foam layer, or taller coils with more give |
| Firmer, more supportive feel | Pocket Spring | No added soft layer over the coils |
| Kids or pets in the house | No-zag & Pocket Spring | Newilla’s removable, washable covers |
| Runs warm at night | Double Spring, No-zag & Pocket Spring | No-zag layers leave air space and help the assembly breathe |
Where fabric and toppers fit
The comfort system determines how a sofa bed feels underneath you. Fabric determines how it feels against you, and how it holds up. Those are separate decisions — every collection is available across a wide range of fabrics, and the upholstery choice does not change the mattress construction beneath it.
If you’ve already chosen a model and want to adjust the sleeping surface slightly, a topper is the low-commitment option. We carry one in accessories, and it stores in its own bag when the sofa is folded. A topper adds softness; it won’t convert a seating-focused system into an everyday mattress, so choose the underlying system for your actual use case first.
Frequently asked questions
Which Innovation Living sofa bed is best for sleeping every night? The Pocket Spring Dual models — Osvald, Cone, and Walis — carry an explicit everyday-sleeping recommendation. Double Spring models, Neah and Vilander, are also built for daily use. Both systems pair a pocket spring core with enough soft layering above it to work as a nightly surface.
What is the difference between no-zag springs and pocket springs? Pocket springs are individually wrapped coils that compress independently and contour to your body. No-zag springs are a broader suspension layer beneath the seat that absorbs pressure and prevents bottoming out. Several systems use both, stacked, because they solve different problems.
Is Double Spring the same as the no-zag and pocket spring system on Newilla? No. Both combine the two spring types, but Newilla adds a hyper soft foam layer and uses a solid wood frame, while Double Spring models use a durable metal frame without that extra layer. Newilla feels softer through the top; Neah and Vilander feel firmer and more structured.
Do all Innovation Living sofa beds use springs? Every system covered here is spring-based. They differ in which springs, how many layers, and what frame carries them — not in whether springs are present at all.
Does the fabric I choose affect comfort? Not the mattress construction. Fabric affects surface texture, durability, and cleanability. The comfort system beneath is fixed by the collection you choose.
