It does exactly what I had hoped for
I couldn't sit in the bathtub without a cushion for about a year. It does not absorb water, stick to the bottom of tub nor look or feel fancy. It does however, allow me sit without pain, move freely without slipping(though it does move because it floats without weight on it). It air dried just fine, I use bath salts and other products so wiping it with a cloth is a good idea to keep it clean  It is lightweight and sturdy. I recommend this to someone who has lower back trouble, sciatic issues, surgery or just uncomfortable sitting on the hard bottom of a bathtub!
