No—it’s designed to regain its shape after use. SitHaven’s memory foam compresses beneath you while you sit, then regains its shape after use. The sculpted cushion is designed to cradle your hips and thighs, rather than feel like a flat seat pad.
Yes—it’s designed for longer sitting sessions. Sculpted memory foam adds cushioning beneath your hips and thighs for long days at your desk. It adapts under seated weight, giving your everyday chair a more cushioned feel. Try it during your normal workday to find out how it feels for you.
Fit depends on your chair. The cushion measures 16.1 × 14.6 inches—compare this with your chair’s seat before ordering so the base is fully supported. We’ve designed it to minimize added height, but it does add some. Adjust your chair accordingly so your feet stay supported and your desk remains within comfortable reach.
The grippy base helps reduce sliding. Place the cushion flat and centered on your chair, with its base fully supported by the seat. How securely it sits depends on your chair’s size, shape, and upholstery. Check the fit before ordering, then try it in your own setup during your 30-day trial.
Try it in your chair for 30 days. Sit on it. Work on it. If it’s not comfortable for you, contact us within 30 days of delivery for a refund.

The sculpted seat cushion for a more comfortable workday.
My chair was still perfectly usable—the seat just wasn’t comfortable anymore. I wanted to try a cushion before replacing the whole thing. After checking the fit and adjusting the chair height, the extra cushioning made my desk setup feel much better. A simple upgrade without starting over.

My old cushion kept sliding forward, so I was constantly pulling it back into place. SitHaven stays put much better on my office chair. I can sit down and get on with work without stopping to straighten the cushion every few minutes.

My biggest concern was whether it would fit my chair and put me too high at my desk. I checked the measurements before ordering and lowered my chair slightly once it arrived. That small adjustment made the setup work for me.

Your first week, in your own chair.
You sit down and feel the extra cushioning beneath your hips and thighs. The familiar hardness of your chair gives way to a softer, more cushioned seat.
The goal: less shuffling around to find a comfortable spot. Fewer moments distracted by a hard seat. Just extra cushioning beneath you while you get on with your day.

Yes—provided each chair supports the cushion’s full base. Check each seat separately and adjust the setup when you move it; a good fit on one chair does not guarantee the same fit on another.
No. Body size, sitting position, chair shape and personal preference can all change how a cushion feels. Use your own comfort in your everyday setup as the guide.
It can add cushioning to a usable seat, but it cannot repair a broken frame, unstable base or faulty adjustment mechanism. Start with a stable chair that works properly.
Yes. Extra cushioning does not replace movement. Change position regularly and take short breaks to stand or walk during your workday.
