Firm in a good way

Not the squishy kind that goes flat. The foam gives slowly and comes back. After a full day it still feels the same.

Kevin L.

Both pieces have their place.

The seat feels shaped without taking over my chair. I move the lumbar cushion slightly higher when I sit down.

Emily R.

Works on a rolling stool

I use it on a rolling stool at my drafting table. Seat cushion fits fine.

Erin G.

Holds up well

A few weeks in and the foam looks and feels the same as day one.

Justin E.

Easy to move between chairs.

I use the set at home and in the office. Checking the space between the armrests first helped me choose where it works best.

Marcus T.

Love the green

Such a calm color. It makes my small desk corner feel more put together.

Isabella R.

Cute and functional

I love how it looks and it helps me sit better.

Sierra B.

A simple desk upgrade.

I like being able to place the two cushions separately. It took a few adjustments to find the setup I prefer.

Jordan P.

Long meetings are easier

I sit through a lot of video calls. I shift around a lot less than I used to.

Rachel K.

Great gift

Bought for my dad who works from home. He texted me a photo of it on his chair the same day.

Lauren B.

Would buy again

Already recommending it to friends who work from home.

Evan L.

The color is nicer in person

The green is soft and not loud at all. It matches my home office better than black would have.

Monica G.

Fix the setup, not the chair.

With SitContour Duo: the same chair with the seat cushion and the lumbar cushion

Chair alone: sitting on the chair without cushions

What a workday feels like with the set.

Settle in once.

Sit down and start. The seat cushion gives you a shaped layer to sit on, and the lumbar cushion fills the gap behind your lower back.

Less shifting around.

No pushing a strap-on pillow back up or folding a sweater behind you. Each piece stays where you put it.
