Problem:  I have a Tempurpedic mattress, which is 8-9" deep.  Most, if
not all, fitted sheets these days [USA] are made for deep, quilted
mattresses.  Hence, within a day of putting them on [even jersey
sheets, which have stretch], they become very wrinkled and
uncomfortable.  Gadgets such as corner clips to go under the mattress
& "Tugs" don't work adequately to keep the fitted sheet smooth. 
Vendors claim that sheets designed for deeper mattresses which have
vertical stretch on their corners "work" for "any" depth mattress, but
I'm skeptical, because you still have all the excess material which
will "wrinkle up" on top.  I would not mind leads to such sheets with
vertical stretch corners, but the jury is out on whether they really
"work".

2 possible solutions I have Google'd:

1.  Stretch terry fitted sheets.  This item exists a) in USA for
baby's cribs, and b) in some European countries [though if found in
Europe, then the problem exists of finding a correct size to fit a USA
queen size mattress].  I found a lead via a UK Bed forum site from a
USA woman looking for these for a double bed, dated back to 12-04. [I
registered there & have emailed that woman, Christie, to see if she
found anything--too soon to see if she answers.] The suggested UK
links she was given were not useful.   I tried to Google UK for
stretch terry sheets, to no avail.  Sweden is another option,
notwithstanding the size issue noted above.

2.  8-9" fitted [cotton] sheets.  These are what was "standard" before
the advent of puffy, quilted mattresses, but now appear to be no
longer available.  I've tried Googling 8" fitted sheets, 9" fitted
sheets, standard fitted sheets. [this latter--"standard"--resulted in
Bed, Bath & Beyond's explanation of differing depths of fitted sheets;
 but, their site doesn't appear to have any "standards".  [I got
impatient & discouraged after one page of listings.]

My next step is to start marketing the damn things myself!  This is
your mission.  This tape will self-destruct in 10 seconds.  Good luck.

Hi Karen,

Well, my mattress is over 10" deep and my fitted sheets did fit nice
and tight, however after sleeping one or two nights, it got all
wrinkly and uncomfortable.  I found a solution that works for me.

Now, you're going to laugh - but I quit using sheets!  :)

I found this to be quite a bit more comfortable than using sheets, but
again, this works for me and might not appeal to anyone else.

I have a nice mattress cover on the bed.  (In fact, I have mattress
covers on the box springs - but that's another topic.)

I take a quilt and place it bottom side up (so the side you would put
on top of you is the inside part) on the mattress.  No need to tuck it
in... it stays nicely put.  That's my bottom fitted sheet - so to
speak!

I then take another quilt and place it on top of the bottom quilt. 
The top quilt is facing the correct way.  It's pulled up to about
halfway on top of my pillows instead of pulled up to the top of the
mattress... this leaves a large amount at the bottom of the bed to
tuck both quilts in under the mattress, keeping everything in place.

(Basically, I'm sleeping between two quilts and it feels very soft and cozy.)

I place a comforter over top of the top quilt and sleep like a baby.
Making the bed in the morning is a snap.  Just pull the top quilt over
my pillows about halfway, and then pull up the comforter.

I live in the hot southwest and even during the summer, this is very
cool and comfy for me.


Best regards,
tlspiegel
