I have a California King bed and buying sheets for it has been an annoying experience, until now.  The fitted sheet never seems to really fit.  It's either too big leaving annoying wrinkles that make sleep uncomfortable (yea, I'm kind of like the princess and the pea when it comes to my bed) or they are so tight that getting them on requires the strength of a weight lifter.  These sheets were perfect.  No wrinkles, no weight lifting.  They are soft, and feel luxurious.  I'll be buying all my sheets from here in the future.  Oh - and they come with 4 - yes 4 - pillowcases!  I love this company.
