Cassius, Supremax, and Ran share the same mattress construction, the same queen sleeping format, and the same general silhouette. If you’ve narrowed your search to this family, the mattress isn’t the decision anymore — the legs, the arms, and one detail about the matching ottoman are.
What all three share
All three are built on Excess Pocket Spring: taller coils than the standard Pocket Spring system, which compress further and give a softer feel in both sofa and bed positions. Layer specification is identical across the family: fabric, fiberfill, high resilient foam, pocket spring, fibertex, metal mesh, rigid metal frame.
All three are queen sleepers, all three fold with an easy conversion method, and all three are part of what Innovation Living calls the Deluxe Excess Lounger family — a design lineage dating to 2008, considerably older than the Neah/Vilander/Newilla generation launched in 2023–2024. If you want an established, long-running design rather than the newest release, this family is where to look.
Where they differ
Cassius has a classic sofa silhouette with stitched, pull-down styling on chrome legs — a timeless European profile that reads more like a conventional sofa than a mechanism-forward piece. Bed size is 63″ x 79″.
Supremax is positioned specifically around compact urban living — a space-saving alternative in the same queen format, also on chrome legs with a matte black steel frame. Bed size is also 63″ x 79″. Between Cassius and Supremax, the difference is closer to styling emphasis than function; both share legs, frame, and bed size.
Ran is the outlier, and it’s a real one: curved walnut wood arms instead of chrome-legged upholstery. It’s the only model in this trio — and one of the only models in the whole range — with a wood-arm silhouette rather than a metal or fully upholstered one. If you want the Excess Pocket Spring mattress but a warmer, more traditional material palette, Ran is the answer.
The ottoman detail that actually matters
A matching ottoman is documented for Cassius and Supremax — it pairs with the sofa to form a chaise lounge or extra seating, and Innovation Living explicitly recommends adding it to complete the arrangement. Whether an equivalent ottoman exists for Ran isn’t confirmed as of this writing.
If a chaise configuration or the flexibility to add one later matters to you, that alone may settle the choice between Ran and the other two.

How to decide
If you want a chrome-legged, classic sofa profile, Cassius and Supremax are close enough that the decision comes down to which name and exact proportions you prefer in person — both share bed size, frame, and the ottoman option.
If you want warm wood rather than metal, Ran is the clear choice, and it’s differentiated enough from the other two to be worth comparing in a showroom rather than choosing on spec alone.
If a chaise or extra-seating ottoman is part of your plan, confirm availability for your chosen model before ordering — it’s documented for Cassius and Supremax, not yet confirmed for Ran.
