So far, I believe this heated seat cushion will be a god send come winter time. Working on the computer all the time, my back really gets to hurting by the end of the day. The heat from this cushion helps (as well as the cushion itself too). It plugs into a USB port and begins to heat almost immediately.
This cushion is good for back pain and sciatica pain. The cushion heats to 122 degrees in just a short time. It's a great way to relive pain. This cushion is a dark blue, so it's not going to show dirty as quick as a lighter colored cushion. The cover also has a zipper so that you can remove it to wash it as needed.
You can get this item on Amazon here . See my review on YouTube here:
All in all I really like this heated seat cushion. It really helps to deal with back pain in a more natural way which is always nice. It seems as though it is constructed well and the foam cushion holds it shape so far. I believe the inner cushion is a memory foam type of cushion, but it's very comfortable.
Have a great day!
