Shop for a desk cushion and the same words come back again and again: comfort, support, memory foam. They describe a material and a mood. They don't tell you whether a cushion is right for your chair, or whether you need one cushion or two.
So skip the adjectives. Start with your own chair and three questions. Your answers point to one of four options, and only one of them is the thing we sell.
Question 1: Where does your chair fall short?
A chair meets you in two places: under you, at the seat, and behind you, at your lower back. Think about a long desk day and notice which one takes your attention.
- Under you: you slide toward the front of the seat or keep shifting around.
- Behind you: there's a gap between your lower back and the backrest, and you've filled it with a folded sweater or a pillow.
- Both: some of each, depending on the day.
Question 2: Do you want to keep your chair?
If your chair is basically sound and you'd rather not spend hundreds replacing it, you're choosing between cushions. If it's due to be replaced anyway, put the money toward the chair.
Question 3: Can your chair take a cushion?
Any seat or lumbar cushion depends on the chair underneath it. For SitContour Duo, that means:
- A stable chair
- A seat the cushion can sit fully on
- A backrest
- Room under your desk for extra seat height, with your feet still on stable support
- Very small or deeply bucketed seats
- Stools and other seats without a backrest
Your answers, mapped to an option
| If your answers are | Look at | What it leaves as is |
|---|---|---|
| Only the seat, and you're keeping the chair | A seat cushion | Behind your lower back |
| Only the gap behind you, and you're keeping the chair | A lumbar pillow | The seat |
| Both places, on a chair that can take a cushion | A seat and lumbar set | Your chair, which you keep |
| A chair that can't take a cushion, or is due for replacing | A different chair | Nothing: it replaces your chair |
Other options vary by brand and model, so treat this as a map, not a verdict. Here's the thinking behind each row.
Only the seat? A seat cushion on its own may be enough
If your backrest already sits comfortably against your lower back and it's only the seat you notice, one seat cushion may be all you need. We'd rather you buy the piece you'll use than a set you half use. With any seat cushion, check two things: that it sits fully on your chair's seat, and how much height it adds against your desk.
Only the gap behind you? A lumbar pillow, with or without a strap
A lumbar pillow goes behind your lower back and leaves the seat alone. Some strap to the chair; some simply rest against the backrest. If you've owned a strap-on pillow, you may already know the routine of pushing it back up. Either way, it only deals with one of the two places.
Both? Then the order you place them in matters
Here's the detail that's easy to miss when you buy two cushions separately. A seat cushion raises you. Once you're sitting a little higher, your lower back meets the backrest at a different point. So whatever goes behind your back should be placed after the seat cushion is in, at the height your back is now.
That's the thinking behind SitContour Duo: a contoured memory-foam seat cushion and a separate lumbar cushion in one set. Each piece is positioned on its own. Seat cushion first, then the lumbar cushion at your lower back, and if it isn't quite where you want it, you move that piece without shifting the seat cushion.
The trade-off, stated plainly
No strap is supplied with the lumbar cushion. It rests against your backrest, so your chair needs a backrest for it to rest against, and when the set arrives you should check that it stays where you put it. If you want a lumbar cushion that straps on, choose one that does.
Chair can't take a cushion? Then the honest answer is a different chair
Cushions add to a chair; they don't replace one. If your chair isn't stable, has no backrest, or has a very small or deeply bucketed seat, no cushion set is the right fix, including ours.
If your answer is both: what the set costs, and how to try it

Questions readers ask
Can I buy a seat cushion and a lumbar pillow separately instead?
Yes. If you do, place the seat cushion first, then position the lumbar pillow where your lower back is once you're sitting on it. SitContour Duo puts both pieces in one set, each positioned on its own.
Does SitContour Duo's seat cushion make me sit higher?
Yes, it adds height. Check desk clearance and that your feet have stable support, and adjust your chair if needed.
Does the lumbar cushion have a strap?
No strap is supplied. It rests against your backrest, behind your lower back.
What is slow-rebound memory foam?
Foam that gives way slowly when you press into it, shaping to you instead of pushing back, and fills back in when you take the pressure away.
What if the set doesn't suit my chair?
Request a return within 60 days of delivery. We send a prepaid return label and refund the product price within 3–5 business days once the return arrives and is checked. Original delivery charges aren't refunded.
