In the last year I upgraded to a line of 415TC Percale sheets by Peru Pima. They sell them on Amazon as well as their own website. They were recommended here by (I think) @Arlene_Larsson. I do a lot of turnovers but 99% of the time I take the sheets off, wash them and put them right back on the bed so these sheets have been laundered at least 60 times since I purchased them in May. Last week I noticed a small hole in the corner of one pillowcase. It could be dog or cat related (a claw or tooth) or snagged on something else. I went online to see about buying a replacement pair of pillowcases and noticed that the Amazon ad said they have a lifetime guarantee if they ever rip or pull. So I emailed them on 9/26 via Amazon and included a picture of the hole and my order number. I was sent a reply within hours and my replacement set of pillowcases arrived today.
As discussed in another thread on sheets, these aren’t the least expensive sheets on the market but for a good weight percale which is sold as a luxury sheet, they were reasonable. If you sign up on their website you can get 15% off the first order or you can watch Amazon for a sale. I got one queen set on sale for $80.
So if anyone is looking for a nice set of sheets (they also have higher thread count sateens) with outstanding customer service I recommend them.
