Many years ago, we selected a new mattress and box spring at the furniture store. After a week of agony, I insisted we go back to the store and lay down on the one we thought was so comfortable. The same salesman came to see what we were doing and at some point, I noticed the tag was a different color than the one we had at home. I couldn’t recall what it said, but I knew it was not the same color. He told me to call him when we got home and read the tag.
When I did that, he almost flipped. He said the one we had is a special order because it’s rock-hard and they don’t have much call for it. He figured when the mattress supply was delivered, this mattress was set off and never got loaded again so it got mixed into their inventory. The store immediately brought the right one and hauled “the beast” away. We’re still using the right one and I know it’s over 20 years old now.
