K.O.
We have an Kingsdown King size. I found the best sheets at Marshalls Super Store. I got 800 count egyptian cotton (like silk) for $70. I bought a pair of 1000 count cotton from Target and they do not even compare. I think anything over 600 ct. automatically is a deeper pocket, might be 400. But Marshall rocks - did you check Overstock.com? My girlfriend swears by them.
