Solid Wood Frame. No Clips. No Creaking. Beautiful from Every Angle.
Most modular sofas use interlocking clips and connectors that loosen over time. The Comma is built around a solid hardwood frame. No interlocking parts means nothing shifts, nothing loosens, nothing creaks under real daily use. And without clips or connectors on show, every side looks just as good as the front.
Designed Around How You Actually Sit.
Most sofas are built for showrooms. The Comma was built for real life. The 44cm seat height means sitting down and getting up feels completely natural, no perching on the edge, no pulling yourself forward. The 64cm seat depth supports your full posture whether you are sitting upright, leaning back or putting your feet up. Your back is supported exactly where it needs to be.
Replace covers and Modules, not couches
Change your cover, not your sofa. Add a module when your space grows. The Comma Sofa adapts so you never have to start over.
In real homes. Get your inspiration!
Not a showroom. Not a set. These are actual homes where the Comma lives every day shared by the people who love it.

Pearl (like Chenille): velvety
Clay, Haze. (like Linen) : woven texture.
Recycled Moon &Juniper (like Bouclé): ultra soft, made from 370 recycled bottles per sofa.

Multilayered foam. Soft on the surface, supportive underneath. Top layer softens over the first two to three weeks. Core holds shape long term.
Each module is rated to 150kg static load. The hardwood frame is built to exceed typical residential use across the 5-year warranty period. If you have a specific load requirement, contact us before purchasing.
The 44cm seat height is on the higher end of the residential sofa range, which makes standing up easier than a low-slung design. If you need specific ergonomic advice, contact us with your requirements and we will give you an honest answer.
64cm seat depth. That is enough to sit cross-legged or recline with legs extended on a chaise. It is intentionally deeper than a standard office-style sofa because the Comma is built for living rooms, not waiting rooms.

Blot immediately. Do not rub. Spot clean or remove the cover and wash. Covers come off in minutes so you can be washing within five minutes of a spill.
Minor pilling can occur in the first few weeks. Use a fabric shaver or lint roller.
Bouclé is the most likely due to its curled texture.
Avoid sustained direct sunlight. Use sheer curtains for strong afternoon sun. Lighter colourways show fading less visibly.
Lifts off with a lint roller on all five fabrics. Woven polyester is more resistant to claw pulls than natural fibres. Replacement covers available individually.
The Comma itself is not independently certified. Our factories and fabric suppliers are. Between them, they hold certifications:
for responsible timber, OEKO-TEX Standard 100 for chemical-safe fabric, Higg Index for environmental impact, REACH for EU chemical compliance, Global Recycled Standard for verified recycled content, and ZDHC for zero hazardous chemical discharge.
Approx 370 plastic bottles are woven into every Recycled Bouclé cover.
The fibres are OEKO-TEX certified, meaning no toxic residue carries through from the recycling process.
Yes. The solid hardwood frame is FSC certified, meaning the timber is traceable to responsibly managed forests. No engineered wood or MDF is used in the primary structure.
Traditional sofas are replaced as a whole unit when one component fails. With the Comma, you replace only what needs replacing, a single cover, one module, not the entire piece. That is the core of our sustainability argument: longevity by design.
Our delivery team removes all packaging on the day. Cardboard is recycled and wrap materials are consolidated. Nothing is left for you to dispose of.
Yes. Covers,, alligator clips, and individual modules are stocked.
We design for repairability, not replacement cycles.

Yes. Each swatch is a cut section of the production fabric. You can feel the bouclé loop, the linen weave, and the chenille pile before committing. Screen renders cannot replicate tactile texture.
