This is the most overrated item I have ever come across. When I wanted to send them (1 should have buy one and get one free) but I paid for two (no free).
I keep sending them emails and kept receiving another question (one at a time) that has me flusted. So needless to say I gave up and threw the pillows away. They didn't help my bad back, but instead made it worse.
My pillows did not do what as advertised which amounts to false advertising.
Reason of review: Poor customer service.
Monetary Loss: $110.
Preferred solution: Full refund.
I liked: Very much overpriced.
