I chucked this pad on the floor where I was working and adjusted its placing with my feet. Once happy I stood on it and felt more comfortable almost immediately and joint pains lessened too.
Thick, squashy 18 inch x 24 inch foam rubber mat has good, consistent density throughout with exactly the right thickness; I don't notice stepping up to it and neither do I feel the floor underneath.
The black coloring is also consistent and it looks good even after hours of use. The smooth top surface also offers plenty of grip and does not feel in any way slippery even with my dusty shoes and the patterned under side and my body weight keep it in place. Dusty dirt was easily transferred from my footwear to the mat and it wipes clean with a damp cloth. The pad is a good size for a small area while providing a comfortable base.
