Size of one piece: 30cm x 30cm Brown: 12 pieces Beige: 12 pieces Cream: 5 pieces Total: 29 pieces Used for about a year. I used them by laying them on the flooring of the children's playroom and then putting a rug on top. There are a few small scratches and dents, but I think they are still in good condition and can be used. All pieces have been wiped with disinfectant wipes and home cleaned.
