I have a really thick Tempurpedic mattress too and I have found that Shabby Chic's target line fits my mattress very well and I really like how the sheets feel. I tried to get some Shabby Chic sheets to fit a regular twin size bed in our house and the sheets were ridicously too big. If her style doesn't go with your room you could get the sheets in plain white. I have also found that with my Tempurpedic mattress I have to use a mattress pad cover or my sheets slide right off the bed after one or two nights. I had heard that you weren't supposed to use a mattress pad cover with these types of mattresses but I still do. I love my mattress though. Good luck.

Thanks kimberlysaint. I will check those out. BTW, we bought the Tempurpedic mattress pad/protector. I didn't want to at first because the mattress feels so wonderful. But it is working out great, and we wanted to protect the mattress.

I can't find bedding to fit mine correctly. We have the California Twin, which are extra long. They are on seperate frames but we put them together and I make it up as a Queen. Of course, seperate fitted sheets but I use a Queen top sheet which is a little short on the sides but a king is way too long. I do use a King quilt and comforter.

Actually you can find sheets to fit these mattresses for pretty much any depth. You might want to look online. I happen to also have a Tempurpedic and also find it to be the best mattress out there. We did purchase our sheets online as we had troubel finding them locally.

kohls and bed bath and beyond have 20" deep sheets
