One piece, three zones

A curved memory foam shell with a double-wing back. Seat and back in a single piece.

Pulvinar, The shell
01

The shell

Seat base and back panel are molded as one curved piece with a double-wing back, so the cushion holds its shape around you instead of sliding apart into a seat pad here and a back pillow there.

Pulvinar, The core
02

The core

High-density slow-rebound memory foam under a 20 mm upgraded seat pad. It gives where you sit and comes back when you stand, day after day.

Pulvinar, The cover
03

The cover

Four-season spandex fabric, breathable and cool to the touch, with a wrinkle-resistant surface that keeps looking deliberate on a chair people actually see.

3 finishes

Which one is yours

A swatch tells you the colour. This tells you the room it belongs in.

The full lineup, side by side. Every finish below is shot in the room it belongs in.
Pulvinar in Gray, in a workspace

Pulvinar in Gray

Neutral, without going invisible

Gray is the one that survives a room changing around it. It holds its shape against warm wood and cool metal alike, so it still looks right after the desk, the chair and the wall color have all been replaced.

Pulvinar in Black, in a workspace

Pulvinar in Black

The one you do not have to think about

Black recedes into a desk and lets the work be the loudest thing on it. It is the finish that photographs cleanly on a call, holds up against every wood tone, and is almost never the decision anyone regrets.

Pulvinar in Blush, in a workspace

Pulvinar in Blush

Softer, and more sure of itself than it sounds

Pink takes the hard edge off a desk full of black rectangles. Against pale wood and white walls it reads warm and composed rather than loud.

Questions

Good to know before you equip.

What colors does it come in?

Three: gray, black, and blush. All three use the same four-season spandex cover, so the choice is purely which one suits the chair and the room it lives in.

What is it made of?

A high-density slow-rebound memory foam core under a 20 mm upgraded seat pad, wrapped in a four-season spandex cover that is breathable, cool to the touch, and wrinkle-resistant. The base is textured with anti-slip grip strips.

Which chairs does it fit?

Any chair with a flat seat. It is 42 cm wide and 32 cm deep, which covers standard office chairs, dining chairs, and car seats, and the 34 cm back panel rests against the lower part of the chair back. The grip strips hold it on smooth seats without straps.

Can I use it in the car?

Yes. Car seats are one of the three intended placements alongside office and home. It is light and portable, and the carry handle makes moving it from desk to driver's seat a one-hand job.

How is this different from buying a seat cushion and a back pillow separately?

It is one molded shell. Separate cushions migrate independently, and the back pillow usually ends up on the floor. The Pulvinar's seat and double-wing back are a single piece, so the geometry you sat down with is the geometry you still have an hour later.

Will it slide around on the seat?

The base is textured and fitted with grip strips, so it stays planted on flat seats without any strap around the chair. Pick it up by the handle when you want it somewhere else.

Do you sell to offices or in volume?

Yes. Pricing steps down automatically through 5 units in the cart. This is a freight-heavy item, so orders above 5 units are quoted individually. Write in with your quantity and destination and you will get a firm number.
