This is the second set of 800 thread sheets I've ordered from Overstock and they are great. The king size bottom sheet fits snuggly on the mattress and the top sheet fits well with enough hang on the sides and at the bottom. They're crisp and comfy to lay on. However, they are 100% cotton and do wrinkle even after taking them directly out of the dryer. Would not suggest using much if any bleach with them as it tends to weaken the threading. Hot sudsy water is enough to get them really clean. Would order again.
