$700 · King size Casper mattress and grey bed

King size, 10” thick, Casper mattress. Fairly new, purchased new 3 years ago. The tag says it was manufactured in 2016. Has always been used with the mattress protector on top of the zipped mattress protector that the mattress comes in. Couple small nicks out of the footboard, but those are usually hidden by whatever blanket is on the bed. Selling for my Mom, she is downsizing. Prefer to sell mattress and bed together.
