“This is a very high-quality, well-made product. I'm using it between my lower legs when I lie on my side in bed to help with sciatic pain. I put it with one end between my knees and the other between my ankles. It compresses a slight bit, but there is still plenty of thickness to make it supportive and comfortable.. It did have an objectionable odor (plasticky/chemical) for a couple of days, but that's gone now.”
