@Stacey180 My Walmart/Better Homes and Gardens/400ct sheets have held up really well over the last three years. We have several sets but they are all in regular rotation with each set getting washed about 2 times a week. I prefer sheets with a pattern to hide any small stains. Each set for a queen was in the $45 range. Our duvet covers are $29 from Amaz-n and I think they are actually microfiber (polyester) but they aren't shiny and they don't feel like depression like most polyester does.
White Egyptian cotton is the best we live in a high tourist destination with many hotels so on the island we have a couple of companies that supply hotels with bedding and towels and they have different grades if you dont want to go 5 star,
