High quality, durable material (thin, not fat squishy foam). Excellent for protecting hard floor surfaces. No smell, rolled out flat right out of the box. However, picture shows the color as brown, but it's black.
Fit my treadmill. Laid flat. Is protecting flooring from machine and sweat. Keep underside of treadmill from collecting floor debris. Have one under elliptical and weight stand as well. Provides good traction.
Bottom Line Yes, I would recommend this to a friend
