Bought for office char that had a seat tilting slight angle
I used an office chair for about a year that had a seat that wasn't horizontal, it had a slight angle that tilted you forward to the point it would cause your legs to slide out fairly easily.  After trying varying items to limit slip and angle issues, ordered this foam pad that when received thought its wedge height/angle would be too much.  but after about 2 months' use and its fairly soft material, it's compressed to be more flat, about half the thickness than when new, which is closer to the dimensions I need to compensate for the non-horizontal seat angle.  Before sitting down, I make sure the wedge is positioned properly (near the seat front edge and pointed toward the read of the  seat).  It's such a lightweight wedge that I need to check the positioning each time.  The texture is rough enough that it doesn't slip too much while seated, but getting up or shifting alot while seated does cause the wedge to move.  Glad the material compressed to a thickness more to my situation, but might be disappointing for someone who expects the material to stay the same shape as when new.
