Seat Cushion for Office Chair – Memory Foam Chair Cushion for Tailbone Pain & Sciatica Relief – Ergonomic Office Seat Cushion for Back Pain – Desk Chair Pillow for Sitting Comfort & Pressure Relief

Good construction, amply sized, and provides a comfortable level of support. Instantly alleviated a good portion of low back pain owing to slumped posture, (hip/pelvis tilt) that, despite being physically fit, can result from hours of sitting in desk chair. To suit the slightly downward-tipping seat, (this particular desk chair seat is deep and angles downward towards the back of the chair like some car seats), I place the wedge further forward; the narrow end of the wedge meets the front edge of the chair seat; the very opposite, thickest end of the wedge is directly under tailbone. The tailbone placement is what matters, (for me). With the thicker end of the wedge directly under tailbone, the tilt is subtle. Tending to think that a higher-raked wedge or one with more stiffness, could possibly exceed the needed adjustment and cause other off-set issues. The next level of support would be padding for lumbar and thoracic which attaches to the seat back, which I believe this company also makes. Then the rest of the spine can remain straight and supported as well. Thanks very much!!

This pillow wedge has been perfect for my needs. It is used for the car seat. I've tried other car seat pillow wedges and they have tended to sag. This one, however, is very firm, and I feel much more comfortable when driving the car. I almost traded the car in until I started using this pillow. Highly recommend it for shorter people whose car headrest is way too high.

I purchased a Bonmedico Orthopedic pillow for a family member. He drives a lot of miles every week and recently had a flare up of painful hemorrhoids. I shopped a lot of cushions/pillows and read way too many customer reviews. Finally, this pillow seemed to be the right one. I bought a size large (6'2," 170 pounds) and it fits. When the pillow arrived, I inspected it and was impressed. The memory foam/gel is overall very firm and comfortable. It provides a lot of support and that feels good. The forward and backward cutouts in the pillow apparently cause a distribution of weight that depressurizes the tailbone. My family member used it 2-4 hours p/day, five days a week for couple of weeks. Yesterday he informed me that the pillow gave him immediate relief and he had rapid improvement of his condition. His pain has almost completely subsided and his hemorrhoids are nearly healed. This pillow was an inexpensive and great investment. I am pleased that something so small made a huge difference in his life.

Love it! The seat of my refurbished Herman Miller had gone flat, and I didn't want to the expense of buying a new one--even a refurbished one is pricey--and with refurbished, you never know the quality you will get. I bought one refurbished Herman Miller Ambi for my office, and it's seriously the most comfortable chair I've ever had, even five years later (though I only spend 10 hours per week in my office). But the refurbed HM I bought for home is now flat-bottomed after just a couple of years.SO seat cushion is the answer. This one is great--especially compared to the others I've tried. The size is just right. It nearly covers the whole chair. It's not too thick--the runner up cushion is like 4-inches thick, and it's comfy, but it's too tall to be practical unless your chair will lower substantially (product number: B01MRWWDUG). Others were too firm (TanYoo product number: B07P85JB7G) or too sweaty (Wondergel aka Purple product number: B01MCWVVCN). Before this one, I was just using some regular dining chair pads from Costco, which were fine but they eventually flatten out too.This one was Goldilocks JUST RIGHT. I've had it for weeks now, and my ONLY complaint is that when I sit on it in a nighty that doesn't cover my butt when I sit, the fabric is a little uncomfy. Easily resolved: put it in a pillowcase. Now it even looks a little more fashionable, and I have another washable layer to keep it fresh.PROS- Super comfy! Gives new life to flat-bottomed chairs.- Removable fabric case can be washed.- Case has handle for carrying, lol.- Memory foam so it won't go flat over time. Why aren't chair seats memory foam by now already, huh?- Just the right size.CON- seat case fabric is ever so slightly scratchy on bare skin. Put it in a regular pillowcase if it bothers you.- that is literally the only con.

I have purchased three of these pillows (one for different chairs in different locations). As a product, the donut pillows have worked great for me and my nether regions (with out getting graphic). So on that front, I rate it a five star.However, while I'm staying in a remote location, I thought I'd pick up the third pillow to use there. When I got it, I discovered that it had already been previously opened and obviously returned. As such, I was shipped someone else's return, and that irritates me to no end.
