I have four exercise mats by the company Power Systems. As seen in the pictures the approximate size is 58 in by 24in. I couldn’t measure the thickness of the cushion in the mat, but it is roughly pinkie finger thick. All mats will be sanitized and clean! One of mats has slight wear on it (I could only post 5 pictures but can send you an image of it, just a few scratches) and that mat has a reduced price of $8. Each mat is $10 but if you buy all four, the price drops to $35
