Support for Long Hours at the Desk
I like it. I spend a lot of time sitting at my desk, and this seat cushion from medoliving has made a world of difference. The ergonomic design with the U-shaped cutout takes the pressure off my tailbone and provides excellent support for my lower back and hips. It’s incredibly comfortable and maintains its shape even after hours of use.The cushion fits perfectly on my office chair, and the fabric cover feels soft, breathable, and high-quality. It’s clear that a lot of thought went into the design and materials. I’ve noticed a significant reduction in discomfort after using it regularly — no more sore back or numb legs.

85% Relief for Tailbone Pain, Works, but Slides on Some Chairs
Size used: 17 × 14.6 × 3.54 inUse case: Full-time office chair (sedentary work)What I felt: This cushion meaningfully reduces tailbone/coccyx discomfort while seated. For me, pain is cut by ~85% during normal sitting. It hasn’t eliminated the discomfort when standing up from the chair, that moment still twinges, but it’s noticeably less intense than without the cushion.Position matters: When the cushion is in the ideal position, relief is excellent. The issue is the bottom isn’t grippy enough, so it can slide forward on my chair. Whenever it shifts, the pressure returns and pain increases until I readjust it.ProsSignificant coccyx relief while seated (about 85% improvement for me)Comfortable thickness (3.5″) distributes pressure wellSize fits a standard office chair without overhangConsBase lacks traction; tends to slide forward on some chair fabricsRelief is position-dependent; requires occasional readjustmentDoesn’t fully remove the pain spike when rising from the chairTips that helpedAdd a small piece of non-slip shelf liner/rug pad under the cushion.Mark your ideal placement (tape on the seat) to reset quickly after breaks.Reposition before long calls or deep-focus sessions.Bottom line: If you’re seeking meaningful tailbone relief while seated, this delivers. Just plan a quick anti-slip fix if your chair fabric is slick, and keep expectations realistic for that brief pain on standing. Overall, a solid improvement in daily comfort.

Made Long Sitting Days So Much More Comfortable
I bought the Medisana SC 100 specifically for my office chair, and it has made long workdays much more comfortable. I sit for extended periods, and this cushion provides steady support without feeling too firm or too soft. It helps me stay comfortable without constantly adjusting in my seat.The memory foam keeps its shape throughout the day and doesn’t flatten out after a few hours. I especially like the design, it feels balanced and evenly distributes weight so I’m not putting pressure in one spot.The cover is breathable and easy to remove for cleaning, and the non-slip bottom keeps it securely in place on my office chair. It fits well without hanging over the edges or looking bulky.Overall, it’s a simple upgrade that makes a noticeable difference when you spend most of your day sitting at a desk. Highly recommend for office use.

Great buy & cushion
For the large size , $14 was a great price to try something that most sellers mispresent , have seeing or Velcro issue & content problems . This seller has a good item . Mr used it fresh out of the very nice mfg box put in a Amazon box. Great gift . It’s compressed somewhat , rolled in plastic with breathing holes . Good shade & fabric is soft and sewn well with some adjusting to line up the seams with the foam shape . Nothing a bit of patience & gentle tug , pushing in the foam as you stretch the fabric .. can not fix . In other words – it’s a good buy. firm yet you can push in the foam & it keeps its form.

I bought two of these cushions in different sizes. The are far superior – in design and engineering – to the “doctor recommended” stress relief or ergonomic options. Tip: buy the correct size and use on a harder surface for best results.

I had extreme pain in my tail bone and hip area from many weeks and I was desperately looking something helpful for pain relief while sitting on chair or sofa and I can realize noticeable difference in pain after using this cushion.It is very soft and comfortable with perfect size.I am very happy to buy the best cushion to support my pains.highly recommended.
