Double Mattress (North Oshawa)

looking for a double mattress for my 14 year old son, that is clean, stain-free, and in decent enough quality & in fair enough shape that it can be utilized for at least a few years, and not rock hard to sleep on. my vehicle not large enough to pickup, so i would need it dropped off to my home in North Oshawa area. open to discussion regarding compensation if required.
