I have the Beautyrest 1000 TC Temperature Regulating Antimicrobial Sheet Set (Queen Size - light gray in color).  Upon opening the package, I realized how nice the texture of the sheets were.  I laundered them before placing them on the bed.  They laundered nicely.  The pockets in the fitted sheet are very deep.  I also noticed the fitted sheet has elastic on all four sides to keep it secure on the mattress.  Although, the fitted sheet was a little large for my mattress (my mattress is not super deep, so I expected it to be a little large), it did stay secure during the night.

I woke up a couple of times during the night feeling rather warm.  I shucked some cover, then slept the rest of the night very comfortable.  For this reason, I'm giving these sheets a "4 star" review.
