Bootylicious Seat Cushion. Your booty will thank you. 

Best chair/seat cushion I have tried yet. This cushion arrived clean and nicely packaged, and arrived in less than 48 hours. There was no strange chemical smell like some of the others I tried. It's got a removable and washable velvet fabric over the generous memory foam material that feels exactly like our $5,000 Tempurpedic mattress. The materials and workmanship look perfect. The zipper works easily, and the rubber non-slide coating on the bottom ensures the cushion (and you) won't slide off your seat. I've been using this for two days now - and yesterday I was on it for ten hours during a particularly grueling radio edit session and some online training, and I definitely noticed improvement over the cheap stuffing typically used in office chairs. My back felt great, and my legs weren't uncomfortable as they usually get over a long session. Two thumbs up - if you sit in an office chair for more than four hours a day, pick up one of these Everlasting Comfort seat cushions. Your booty will thank you. Pick one up here: amzn.to/2zgOPw0
