Getting a piece of furniture that's upholstered in pink seemed like it could be a mistake. My seven-year-old daughter saw the photo on the Wayfair site and decided she had to have it, so we took a chance. It is gorgeous! She was the person who helped me assemble it. We LOVE it. I would agree with other reviewers that an 8" mattress for the main bed and a 6" mattress for the trundle are the only applicable sizes. I was going to try a 10" mattress for the main part, but I'm glad I didn't as it would have been too high. The pink shade is so soft, it's almost a neutral. As she gets older, we can switch out the bedding to make it have a more adult feel to it. So glad I took a chance on this. (I repurposed two king size pillows for the top and bottom. They're the perfect width for each bed when laying flat.)
