Milliard King Size Memory Foam Mattress

The mattress has been used for 3 years and was always covered with a fitted sheet. It’s a Queen-size Milliard memory foam mattress that I purchased from Costco. It has 3 cm of memory foam over a high-density foam base, providing firm to medium-firm support. The removable zip cover is machine washable, and the mattress is 8 inches thick. The cover has just been washed and is clean. I’m also including a fitted sheet for free.
