Not for overweight people, warm environments and/or sitting long hours
I weigh 240 lbs. and sit in a warm environment sometimes reaching 80 degrees. This cushion flattens out on me in temperatures over 65 degrees or when sitting for long hours. It's definitely not a cooling cushion and it causes my butt to sweat after a couple of hours. I moved it into my car for the winter and it supports me fine in relatively short trips under 20 miles, but as soon as it gets above 65 it flattens, so it's only good for short trips in the winter for me. It feels slightly lumpy (due to the wide columns) and moving around on it is uncomfortable because it conforms to your shape and locks in to it. So when you move, it feels like you're sitting on a hard, two-level surface. It only goes back to its original shape if you lift it up and shake it out or leave it alone for about an hour or so. I have to shake it at least 10 times a day. No joke. Also the cover isn't non-slip. I constantly have to push it back into position. Occasionally it slips right off the front of the chair!<br /><br />I've been using it for 11 months and it hasn't permanently deformed yet and it shows no sigh of ever doing so. Oh, and the smell is a bit strong, but dissipates after a couple of weeks.
