Up for grabs: a Beautyrest BR800 Medium Twin mattress in practically brand-new condition — because apparently children don't stay small no matter how many times you ask them to.

This mattress lived its best life on the top bunk, where it was rarely slept on and never once complained about the job. Honestly, it worked less than most of us do. No stains, no sagging, no drama. Less than two years old.

Includes a quilted mattress cover, also clean and in great shape.

Why are we parting with it? The bunk bed has been retired, the kids have moved on to full-size beds and full-size attitudes, and this little mattress deserves a home where someone will actually USE it.

FREE — just come pick it up. You haul it, you keep it.

First come, first served. Don't sleep on this. (But seriously, someone should.)
