When I bought a Graco Play YardGraco Family Tree Play Yardin July for my visiting grandson I bought two of these sheets, one sage, one beige to put on it. I wondered if they might be too warm in the Southern California summer, but they were perfect. They are soooo soft and snoozy that little Mitchell seemed to sleep better here than he had in his first 11 weeks of life. They washed perfectly in cold water and low heat on the dryer. My daughter was so pleased with the combination of the Play Yard and sheets that she packed up the whole lot and took them back to Australia. Back in Australia it's winter and the snuggly sheets are still perfect. As a grandma I couldn't have been happier with these products!
