Order a king for your tall queen mattress
Size: Full/Queen(90"x90"), Color: White
I love it! It is so puffy and light. It feels luxurious to go to bed. It is so puffy that it shrinks the width, barely covering my tall queen mattress. I wish I'd ordered a king size.

Very Plush

I usually don’t expect much when I buy new pillows.
However, I have to say this is a great and very comfortable pillow. I am so happy with this purchase.
