Seat below, lumbar behind
Two pieces of contoured memory foam that turn a flat chair into a shaped one.
The seat
A contoured W-profile cushion in slow-rebound memory foam, 7.5 cm deep, with a center ventilation cutout that keeps air moving where a solid cushion traps it.
The lumbar
A curved backrest pillow that fills the gap between your lower back and the chair. Flat chair backs do not curve; this does.
The wedge
The seat cushion is wedge-shaped with an anti-slide design, so it holds its position through the day instead of creeping toward the edge of the chair.

Which one is yours
A swatch tells you the colour. This tells you the room it belongs in.
Tandem in Two-Tone 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.
Tandem in Classic 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.
Tandem in Warm Beige
The neutral that is not gray
Beige carries warmth that gray cannot, which matters in a room lit by lamps rather than windows. It is the quiet choice for a workspace you also happen to live in.
Tandem in Emerald Green
Reads calm, and photographs well
Green takes the clinical edge off a desk that is otherwise all screen and metal. It sits naturally beside wood and plants, and it is the finish that makes a workspace look like somewhere you chose to be.

Questions
Good to know before you equip.
What exactly is in the set?
Two pieces: a contoured W-profile seat cushion with a center ventilation cutout, and a curved lumbar backrest pillow. Both are slow-rebound memory foam in the same colorway.
How thick is the seat cushion?
The cushion profile is 7.5 cm, about 3 inches. Enough to shape and support, not so much that it perches you above the desk height you set your chair for.
Will it slide around on the chair?
It is built not to. The seat cushion is wedge-shaped with an anti-slide design, which is what keeps it planted instead of creeping forward every time you shift.
What is the cutout in the middle for?
Ventilation. The center cutout lets air move through the cushion, so the seat stays breathable through a long stretch instead of building heat under you.
What do the colors actually look like?
All seven are photographed. Two-Tone Gray, Classic Black, Warm Beige, Emerald Green, and Leaf Yellow pair the accent color with a gray base. All Gray is monotone. Blossom Pink sits on a rose base.
Does it work on chairs other than office chairs?
Yes. Nothing attaches to the chair, so the set moves wherever you sit for long stretches: a task chair, a dining chair pressed into desk duty, a hard bench that needed help.
Can I order these for a whole team?
Yes. Trade pricing starts at the second set and runs to the 5-plus tier at $55.95 per set. For larger volumes than the listed tiers, contact us for a quote.
