I like it. It worked out perfectly for my extra firm mattress that was so hard it hurt my sides when sleeping on it alone. I have another topper under this one which is the my pillow topper mattress, then this one  a padded mattress protector that fits over them all. It went from a standard 18” mattress to 26” with 8” of soft wonderfulness! Worked exactly as I had anticipated  hoped for. It stays on  doesn’t slide off but had a smell  can not be washed.
