I bought some that will fit a 20 inch mattress at Dillards. If you ask in the linen department they should be able to help.

Lands' End Home has some nice extra deep sheets. We have one of those "Sleep Number" beds that is extra deep also, and all their sheets fit great.(Look for the depth measurements in the catalog)

Oh how I share your frustration!
I've got a 13.5" mattress. Look at what happens when I buy a fitted sheet that claims to fit a mattress "Up to 17":

It has been very frustrating trying to find sheets that don't make false claims. Are the manufacturers allowing for shrinkage after you wash 100% cotton sheets in hot water? They're dreaming if they expect us not to wash our sheets in hot water. Now I'm looking for a 20" fitted sheet in the hopes that it will fit my 13" mattress. The sheet I have on the bed in the photo barely fits the corners but clearly doesn't fit anywhere else. Isn't there a sheet that tucks completely under the mattress without riding up in the middle?

This sheet came from QVC but the Macy's Charter Club set Macy's does the same thing. We don't have a Dillards in CA, any other suggestions?

oops, sorry for the typo above.

BTW... I have a Cal King bed and I only buy 100% cotton sheets. I don't like the shine of Sateen even if it is all cotton. And I'd prefer not to spend $100 just for a fitted sheet.
(listen to me placing my order. lol... beggers shouldn't be choosy)

I always get mine from JCPenney's.

I bought a couple of these Charter Club sheet sets on sale for guests rooms. Loved them so much I went back and bought 4 more sets. Used a 20% off coupon on top of the sale price too. They are VERY deep - we have a deep mattress plus a Novaform topper and they go on and stay on w/o slipping. Very soft too.

I was searching again and Smartbargains had some Charisma's that claim to fit 20 inches. I may go for it.

I've also heard good things about Land's End, but didn't know their sheets were that deep. Thanks for the tip!

I recently had to shorten two bed skirts. They aren't made in the length that fits my short box springs--distance to the floor. It's simple to do, or take it to a cleaners that does tailoring.

Bedding used to be so simple.

JCPenney Fan here too. I like their Studio line that is wrinkle free and very cool for summer! Guaranteed to fit up to 18" mattress. Just bought another set yesterday as they are 50% off.

Cuddledown. Made in USA, Italy or Portugal (I think). No toxins, common in cheaper sheets imported from China or India.

lindy: Somebody recently stated on another thread that wrinkle-free sheets contain formaldehyde. Just thought I'd pass that info along. :)

I got mine at JCPenney.

These are the ones we get from JCP. They fit wonderfully, never pull off and are very soft.

OS, as timing would have it. A lady advertised 2 sets of Sferra sheets (still in package) on my local Craig's list. I offered her what I'd pay for them at Tuesday Morning. I didn't hear back from her. Maybe she's holding out on a better deal. LOL By the way DH and I love, love, love, our new sheets!!! He commented how much cooler they were then the blends I was using.

Organic...thanks for the heads up on the formaldehyde. I had read about it before but feel since you find it in many household products and it's very water soluable, I'm not concerned. Love my wrinkle free sheets!!

Here is another source for organic sheets. free from additives, etc. Very reasonable prices too.

I have a set from Lands End too. I can't remember if they were labeled as "extra deep" -- I think they were. We have a ridiculously deep mattress too, and it took me forever to find the right fitted sheets. I also splurged and bought a set of Sferra sheets that fit, too.

I got my last set at bedsheet.com 310TC Egyptian cotton luv it! Q set was only $24.99 deep pockets as well
