I only have the blanket, having got it as part of a lot on eBay, but I thought I'd review it since there's so little info on the Sleigh. The blanket has two sides: a plaid flannel side and a black faux-fur side. The faux-fur is so soft and plush. The flannel is green and orangey-red. I wish it were more of a true red.
I agree that two dolls really have to cuddle up to both fit under this. They should have made it a bit bigger if they wanted them to share easily.
It fits fine over one doll.
B-. It gets marked down because of the size and the orangey-ness. Overall, I think it's a high-quality piece that a little girl would enjoy playing with or a collector would enjoy with the Sleigh set.
