Query: Really junk

This product is by far the WORST example of an air cushion EVER!!!The so called coils, what a joke! If this can keep air circulating, your butt and back must be about 3 inches wide, and you must weigh no more than 5 lbs! Good Luck with that.I should have listened to the reviews.I called the company for a Return Number, and was given one, but after I reviewedtheir return policy, I would be spending WAY TOO MUCH, with their restocking, pain taking them back to the Post Office, shipping charges already spent once, so I did keep them, but they really are junk.
