I bought this as a foot rest when sitting in the office and it is a very good product. I like the contours as it helps soothe the soles. The different height settings also work well when reclining the office chair as it provided additional support. Very good.
Might be fine for other people, but did not suit my purposes, and that's the trouble when you can't try out something in advance, so ordered it online ( delivery was prompt ) but wanted it for putting under computer desk to raise feet as bad back not assisted by time in front of the computer.
but just did not do the job for me,
raised my feet too high, and wobbled and felt uncomfortable and aggravated back further alas.
perhaps for a different use may be more functional, but gave it away hoping someone else could benefit from it.
Generally the quality is ok and it's a fair size so large enough, just didn't work for me.
