Mattress, foundation, frame

Queen sized mattress, a foundation, and a frame that we bought for our kids a few years ago (2016) when we dreamed they would sleep in their own bed one day. Unfortunately, that never happened lol. I did sleep in there with them for about a month trying to make the transition, but we all ended up piled back in my bed (to this day). This mattress has ALWAYS had a cover on it, although there is a very, very slight yellowish discoloration on the mattress in some of the seams (picture #5). I called the place where we bought it at, and they explained that mattresses will naturally oxidize, leaving a yellowish tint. It's hardly noticeable, but it is *not a stain of any kind!* AKA my kids have never ever wet the bed lol The tag also had a small stain when we bought it. This frame is discontinued, but I found the TWIN version of it (pictured). *$650 OBO!!!!* Smoke free, pet friendly home. Normal wear and tear on frame and foundation as pictured. MUST PICK UP!! Let's strike a deal!
