Now we know our ABC's. Using soft playful foam, Tadpoles floor mats featuring letters and numbers provide a fun safe environment for your little one. Made of large interlocking foam puzzle pieces with removable letters and numbers, the mats create a soft base for baby and a great look for the room. Use anywhere a padded floor is needed - playroom, den, bedroom, kitchen, basement or garage. Easy to assemble and just as easy to pack up and store when not in use.
