Bought this play mat about 7 weeks ago and am reasonably satisfied. Chose this more expensive mat (£34.99 at the time!) hoping it would be thicker than the alternatives. Whilst the pack dimensions are shown in the Product Information, adding the thickness (approx 11mm) would be of benefit. My 11 mth old has already worked out how to pull the tiles apart - a thicker mat would be more of a challenge. Mat is beginning to show signs of wear - scuffs, nicks and teeth marks but I guess that's to be expected. On the plus side; warmer, softer and cleaner than carpet and spills can easily be cleared up.
