LYUANEC Gel Seat Cushion 19 Inch Large, Double Thicken Layer, Relief Tailbone Pressure, Breathable Honeycomb Design with Washable Non-Slip Cover for Office Chair, Car Seat, Wheelchair (Blue)

I lost a lot of weight, fat and muscle mostly, and my "sit bones" would ache after just a few minutes on a hard seat and about 30 minutes in the car seat. I tried others but they were too high (lifing me up by 50-70mm) or too small (uncomfortably felt the edges of the cushion under my thighs). This seemed just right ... it is large enough to cover the entire car seat and comfy chair, and thin enough not to lift me up to the car roof or leave my feet danglling in mid air. It is not light ... but reasonable... and certainly comfortable for me. Recommended for folk with "sit bone" aches. RTC

It has helped me be able to sit at my computer and get all my work done without having lower back pain. Good quality, well worth the price and shipping was very fast and arrived early

The product listed as large 19X17inches. The actual size is just 13X12 inches. Quality is OK. Same quality and small 13X12 is available for less than Rs 600 in Amazon. Thanks Amazon for easy return and refund. But should take stern action against these type of suppliers

Not comfortable. I would not be able to sit on it for any length of time.

I basically have to sit and sleep in a recliner, and because of the poor quality of padding, I looked for something to sit on for comfort. Am 75 and for the 1st time have a bed sore on my posterior. It can be really painful. I bought this product, and it improved my situation 95%! I have encountered one small issue. If I end up sitting on the edge, obviously the honeycomb design will fold. When it fold, the edge puts pressure on my sore and it is extremely painful, because of the material if I scoot to change positions, it creates drag and worsens the pain. I have found that to be really comfortable, I need to not sit all the way back on the cushion. My suggestion would be to have a larger slip on case, but in that casing attach a border made of another material and is firm, but soft, so the original product sits down in it. That way, there would be a little more support and the edge of the original would not bend down so much! Also, if the case zipper was on 2 sides rather than one, it would make it a lot easier to remove for washing. I do love it, and plan to get the larger size, to maybe lay in my chair with the pad curved up a couple of inches on back of chair to avoid edges. Other than this, I found this pad to be extremely comfortable and I use it also in my wheelchair when I have to go somewhere.
