HIGHLY RECOMMEND. I badly hurt my coccyx 6months ago and bought a cushion at a rehab store for double the price of this product but it was too soft. I chose the Everlasting comfort cushion based on the excellent reviews and it completely lived up to them. Very firm memory foam (no change in shape/support in 6 months), comfortable, wedge angle is great for lifting sit bones and fits perfectly in car seat (driving in bucket seat being the most painful daily activity i have) as well as work chair, dining chair, stool or aeroplane seat. Carry handle is great, i clip that onto a carabeena on my backpack to take with me on the go. Zips off to wash but material looks as new still and no odour after 6 months of daily use. It truly has provided such relief that Ive ordered the same brand lumbar support pillow to try to help make driving more comfortable.
