14 inch deep queen size foam mattress, extra firm. 1 month old. Too firm for my preference. Gently used for 1 month, need to get it out of the apartment to make room for the new one we're replacing it with. We do have cats who have also slept on the mattress (with sheets). Clean and odor free. Must pick up and help move it down 1 flight of stairs.
Here is a link to the mattress off Amazon where I got it: https://www.amazon.com/dp/B0C8HXFKZ3
