ProtoArc Ergonomic Coccyx Seat Cushion for Office Desk Chair

It's a really good product ! Contoured to accommodate your posterior at all points, except coxccys to provide relief from pain. It's comfortable to sit on, having that right blend of softness, yet firm. I bought it for my upcoming hemorrhoid operation, which I haven't received my appointment yet.

Pretty comfortable and has stopped the pain I was getting sat at my computer. Others have said the cushion doesn't slip but I can't agree. This may be down to the chair I am using but it's easy enough to push back into place. I would ta== rather have to occasionally move the cushion than suffer the pain in my tailbone.

Takes some getting used to, but it does help over time I bought this because I was getting pain in my tailbone area from sitting for long periods at my desk (work and gaming). At first it felt a bit strange to sit on. For me, it took about a week of daily use to get used to it, and that’s around the point where I started noticing the pressure easing and the discomfort improving. Once I settled into it, it did help make longer sitting sessions more comfortable. The design spreads your weight more evenly and takes the pressure off the tailbone. So if it feels odd at first, I’d say stick with it and give it time rather than judging it straight away. The cover has a zip so you can take it off to wash, which is a nice practical touch. Mine has held its shape well so far and still looks the same after regular use. The only thing to mention is the price. It works, but it does feel a little on the higher side compared to some similar options. I’d say it’s good value if you can grab it when it’s discounted. I got mine at full price. Overall, not an instant fix, but it genuinely helped after a bit of adjustment time. Worth considering if you spend a lot of hours sitting. I have mine on a secret lab titan chair for size comparison in my pictures.

Really well made Cussion to support your body while sitting down. If you suffer from any joint & general pain issues where chairs are painful to sit in then this product is the way to go. Good memory foam support that's not too soft and not too hard on the body. Provides just the right amount of support while providing pressure relief. Highly recommend but seems to be not one size fits all as this product is specifically designed to take pressure off certain parts of your body so have a look at what kind of support & pressure relief you need. The pillow is slightly too small if you are trying to use it for a gaming chair but is easily fixable as it stays in place on the chair, so when combined with back / lumbar support this pillow is excellent at providing pressure relief. Thank you for this amazing product.

After falling I found this cushion an absolute must-- comfortable shape and helped me get back to normal again taking the pressure off the base of my back

Like many, I bought this ProtoArc seat cushion to relieve pressure during long hours of desk work. For the first few weeks, I was genuinely impressed. The memory foam was firm yet conforming, and the U-shaped design provided excellent support for my tailbone, making my uncomfortable office chair feel great again. The cover was soft, and the non-slip bottom kept it securely in place. Unfortunately, the honeymoon phase was short-lived. After about a month of daily use, the cushion began to lose its effectiveness. The memory foam no longer held its shape and became significantly softer, to the point where I started "bottoming out" against my chair's hard surface. The initial ergonomic benefits vanished, and I was left with a soft, squishy pad that provided no meaningful support for my coccyx or hips. This is a common issue with lower-quality memory foam, and unfortunately, this ProtoArc model seems to be a victim of it. For anyone who sits for extended periods and is heavier or puts a lot of pressure on their seat, this cushion simply doesn't have the durability to maintain its shape and support over time. Conclusion: If you need a very short-term solution for a slightly uncomfortable chair and don't mind replacing it frequently, this cushion might work. However, if you are seeking a truly ergonomic and supportive cushion for consistent, long-term use, especially for coccyx pain, I would strongly recommend looking for a more durable, higher-density memory foam product from a different brand. The initial comfort of this cushion is misleading, and its longevity is very poor.

Definitely helped with aching hips from prolonged sitting

Let me tell you, before this cushion, my office chair and my lower half were locked in a bitter, daily turf war. The chair was winning. Then, I bought the ProtoArc. First of all, the word "coccyx" sounds like a small, aggressive dinosaur, but apparently, it's just my tailbone crying out for help after eight straight hours of spreadsheets. When this arrived, I noticed it had a giant U-shaped bite taken out of the back. At first, I thought, "Did I pay full price for a cushion that's missing a piece?" But no, that little canyon is a magical, zero-gravity hover-zone for your tailbone

Good

Iv tried 3 other cushions from Amazon This is by far the best and finally found want I was looking for the XL version is exactly right its the version id get the large ones others sell are more for kids or very small adults

Best chair cushion I have ever sat on! So good, soft but helps so much, love it was looking for a second but it’s out of stock which is disappointing. Everyone at the office tried it and loved it!

I was a little skeptical after seeing reviews. I shouldn’t have been. I’ve been using it for a few weeks now and sciatica pain and booty pain is completely gone. I went from panic level pain to complete comfort. It’s firm enough to support but plush in all the right ways for comfort. I’ve seen some reviews that it doesn’t stay in play but I personally had not had any issues. I had to drop my chair a good bit to accommodate the added height but nothing bothersome about that. The only note I’d like to make: Men, get the XL. I bought the large, and I’m 5’6 and about 115lbs. My boss tried it (he’s 230lbs) and it was just slightly too small for him.
