I have two boys, three different sizes of Lego's and usually a mess all over my living room. It's nice to see how all of the colors pop against my beige carpet. The quatro's also don't hurt too bad when you step on them. The duplos, not so much. I've been told to purchase the regular, little Lego's to help with my son's fine motor skills, but I really don't look forward to stepping on those. I have two brothers who had Lego's and man, stepping on those HURT!
