I have always liked a rug in my childrens rooms, even though we have always had carpet – Master 6 builds around or on his, and it is comfy when he spends a while playing. But they are nothing on these cool designs; my favourite would have to be the farm, as Master 6 has played farms since about 2 and a half years old.
The best bit is they cost only AU$190 plus shipping, from Bubba Bling. I think the price is excellent, considering the clever designs. They also ship internationally, you just have to email them for a price.
