We bought this cube for our 3 year old. He gets migraines and will put his head on the ground and cover his eyes with his hands to try to make it dark. So when I saw this I decided it was worth the money and it is! :-) We have a comfy blanket covering the ground along with a soft pillow. We threw a bigger solid colored blanket over it. He's learning that when he has a migraine he can crawl in there and lay down to help his head. It really helps! And if he wants one of his sisters to read to him he'll put one side of the blanket up to let light in and they will sit inside the cube to read together. :-) It's solid and was very easy to assemble, even with our son wanting to help and a toddler trying to crawl in, around, and through it the entire time. :-)
