This full size mattress in a guest room looks fine and is in okay shape but is too soft for some adults, even if they don’t weigh a lot. I can feel springs in one spot so I put an eggshell foam mattress topper on it that is like this https://tinyurl.com/wtn2kaa, which solved that problem, but now it’s even softer. You can have the foam topper, too. Some guests loved the result, but not me, and I sleep there sometimes. I have a new one coming Monday so hope to get it out of here soon. FYI, 'full size' is also known as a 'double bed'. I will have to store it in my living room once I take delivery Monday of a replacement so want to find a new home for it swiftly. A box spring is not included. There have been no pets, no smokers, no bugs, no stains, no smells. I don’t know its age; I didn’t buy it. Location is Highland Park. There are 4 steps out the front door to the street and I can help you load it..
