Lightly used King Size Bed. It’s a Blackstone 12” King Size Memory Foam Mattress with Grey Platform Frame! The mattress measures 76 inches wide, 80 inches long and 12 inches thick. The frame is easy to put together. Set includes everything you need – an exclusive Blackstone Memory Foam Mattress and an Upholstered Platform Bed with sturdy wood slats for strong mattress support without a box spring. This bed frame is dark grey. It is only about a year old. The mattress has some light scuffs on one side from moving it. You can see on the up close side picture but no stains. It’s in good condition and still very comfortable. This set retails for 849.99 plus tax from Costco. I am only asking $550 and I will even deliver it for free anywhere. I can also set it up if needed. I can deliver it up to 100 miles.
