I bought this to go on the floor of my daughter's space-themed bedroom (round version). It's expensive, but appears well made. The fibers are long and create variations in color as the catch the light. This may or may not work for certain rooms, but it looks like the moon in hers. It's incredibly soft and cozy too. The strings (fibers) come off from time to time, but so far nothing drastic. its a it delicate to vacuum, but works well in her room.   

Pros: soft, cozy, interesting, large 
Cons: a bit hard to vacuum
