Today's Delivery was a new box springs and mattress set. My old set, purchased in 1991, was loooong past due for replacement, and when I began to have hip and back issues, I knew a new set was necessary.
The new set is much thicker than the old, and I am not happy about investing in new sheets. I love my percale sheets that are older than my old box springs and mattress. They are still in great shape and feel divine. In my opinion, today's sheets are coarse and are poorly made, except for those that nearly require a bank loan to purchase.
Another disadvantages of the new set is its weight: I know that I will not be able to rotate it by myself.
