Query: good lower back release

Wedge is sturdy/firm and comfortable, providing leg elavation that I'd previously concocted with the used of a couple of pillows, which were too soft and slid around during sleep. Didn't notice any foam aroma upon opening packaging, but aired 24 hours anyway (just let sit out on a chair). Husband needs one, just doesn't realize it yet, so may end up ordering another.
