I purchased the standard Queen sheet set in clay and I am really disappointed. I ordered the right size for my mattress (30cm deep fitted sheet) and it is way too loose and bunches up in the middle of the night. The sheets aren't as cool and comfortable for summer as I had imagined, especially considering all of the 5 star reviews. I have purchased my doona cover from here and love it, but the sheet sets are not comfortable or feel nice at all. Think carefully before purchasing as they are very expensive and cannot be returned. I'd rather spend $300 on good cotton ones
