Looking for used interlocking foams

[ynnus]

My baby starts to learn crawl, but I don't want him to craw on the carpet which is around 15 years old. So I'm looking for used interlocking foams play mats to cover a 10*13 room. Please let me know if you happen to have and want to sale them.

Thanks

这个海绵垫不安全，不如地毯。

今天正好有个地毯清洁的deal

Wiki,这个deal没说到什么时候不能用了？不知有没有人用过这种服务，不知对有地毯方间（也是要清理的）的家具要自己搬空吗？
