Picture a typical Tuesday. Not anyone in particular's Tuesday. Probably yours, or close enough.
Nothing dramatic happens on this Tuesday, and that's the point. It's a long desk day in an ordinary chair, and it goes something like this.
9 a.m. You start the day sitting all the way back
Coffee on the left, laptop open, back against the backrest. You nudge the chair height once. For a while, you and the chair are on the same page.
Nobody decides what happens next. It happens a little at a time.
11 a.m. The slow slide forward
A call runs long and you lean in toward the screen. When you sit back, you don't quite go all the way back. By late morning you've crept toward the front of the seat, and the backrest has become something behind you rather than something you use.
1 p.m. The sweater
After lunch you do the thing you've probably done before: fold a sweater, a hoodie or a cushion borrowed from the sofa, and wedge it behind your lower back.
It seems like a good idea. Then you lean forward to type, sit back, and it has shifted. You fold it again. If you own a strap-on lumbar pillow, you may know this version too: push it back up, sit back, push it back up.
3 p.m. The shuffle
Mid-afternoon is when the chair starts competing for your attention. You shift left, then right. You tuck a foot under you and untuck it. Eventually you're perched on the front edge of the seat with your back nowhere near the backrest, which is a strange way to use a chair you picked on purpose.
5 p.m. The browser tab
Before you log off, there's a tab open full of office chairs. Mesh ones. Ones with adjustable everything. You look at the prices, close the tab, and decide your chair is fine. Next Tuesday will look the same.
What that day is really about
Read the day back and a pattern shows up. It isn't about trying harder or sitting better. It's about the two places where you and your chair meet:
- 1Under you, at the seat. That's where the slide forward and the afternoon shuffle happen.
- 2Behind you, at your lower back. That's where the sweater keeps ending up.
Now look at the fixes the day collected. The sweater and the strap-on pillow only deal with the back. A seat cushion on its own would only deal with the seat. The chairs in the browser tab deal with both, at prices you closed the tab on.
That leaves a fourth option: keep the chair you already own, and add something made for each of the two places.
Try this in the chair you're sitting in
Sit all the way back and notice whether there's a gap between your lower back and the backrest. Now slide forward to the front edge of the seat, the 3 p.m. way. Your back leaves the backrest entirely. That's the two-places idea, demonstrated by your own chair.

The same Tuesday, set up differently
Same desk, same chair, same calls. We can't tell you how it will feel for you; nobody honestly can from a web page. What we can show you is what changes in the setup.
9 a.m. Seat cushion first, then the lumbar cushion
You set the contoured memory-foam seat cushion flat on the seat, then place the lumbar cushion against the backrest at your lower back. The order matters: the seat cushion adds height, so the lumbar cushion goes where your back is once you're sitting on it. You check your feet still have stable support and your legs fit under the desk.

11 a.m. Lean in, sit back, move one piece
The call runs long again. The lumbar cushion is its own piece, so if it isn't where you want it when you sit back, you move it without disturbing the seat cushion. No strap is supplied; it rests against your backrest, which is worth checking on your chair in the first few days.
1 p.m. A cushion made for the sweater's spot
Instead of a folded sweater behind your lower back, there's a cushion made for that place.

3 p.m. The honest part
This is where an ad would promise the shuffle disappears. We won't. Comfort is personal, chairs differ, and a web page can't sit in your chair. That's exactly why the set comes with a 60-day home trial: about eight Tuesdays, on your chair, not ours.
5 p.m. Either way, you'll know
If the set suits you, you keep the chair you already own. If it doesn't, you send the set back with a prepaid return label and the product price is refunded. Either way, you found out on your own chair.
Is your chair a match?
- A stable chair with a seat the cushion can sit fully on
- A backrest the lumbar cushion can rest against
- Room under your desk for a little extra seat height
- Very small or deeply bucketed seats
- Stools and other seats without a backrest

Questions readers ask
Is the day in this article a real person's story?
No. It's an illustrative scenario written by Ergola. It isn't a customer account, and the people in the photos are models.
Does the lumbar cushion strap to the chair?
No strap is supplied. It rests against your backrest, behind your lower back, and you position it separately from the seat cushion. Check that it stays in place on your chair.
Is it a medical product?
No. SitContour Duo is a comfort product, not a medical device. If you have a medical condition, talk to a health professional.
