Sheets have only been washed once, so perhaps it's too early to tell. What i do deeply regret is the mattress size they were cut for. I've got a top of the range mattress bought in 2009, and with proper care is still extremely comfortable. But with sheets at 40 cm and a mattress at 22cm, the sheets bunch up; the very thing I was hoping to avoid by buying new sheets! I was prepared to pay up to $400 for the best thing. I'm 74 years old, what else am I going to do with my money when I like nice sheets? (And BTW, 48cm mattresses look like joke mattresses. Talk about the princess and the pea.) Sorry about the rant, but in my little life out here in the bush, and all the rotten pains of galloping old age, having a comfortable bed that I'm spending increasing amounts of time in, is one of the last pleasures. So, if you can find crisp hotel quality sheets, 22cm thick, do let me know. Cheers Peter
