This seat cushion does not get hot or stick to you, which is a good thing. I'm not sure I get why they say it's a cooling seat cushion though as it has nothing on it to cool it, but like I said it doesn't get hot or sticky when it's warm out. So maybe that's what they mean by cooling. Not sure on this one.
The cover unzips so that you can take it off and wash it. However, it doesn't zip all the way across so you will have to squish the cushion to get in or out, but it really isn't a big deal.
You can get it Amazon here
All in all I do like this seat cushion as it is fairly comfortable and easy to clean. I just hope that the cushion will give a little more once I've been using it for a while because it right now it's a bit stiff so I can only use it for a short time. But otherwise this is a great product.
Have a great day!
