Hello People in the House!

Within the theme of giving away what we do not need--
I am purchasing a new mattress and am looking for anyone who would like a queen mattress free of charge. It's not very old (3 years) and it is too soft for my back although it is a medium-firm. Here's all the facts:

Queen Sealy Mattress
Disco Mozart Postropedic
Medium firmness
Purchased at Sleep Country 3 years ago

I'm wondering if anyone knows of a shelter that is in need of a mattress? So if you know of someone, or if you are in need please let me know. I realize that most people are a little hesitant about getting a 2nd hand mattress, but remember it's been maintained in a smoke-free environment and I'm relatively clean. Thanks, over and out Kaile
