[Q]: Buyer: I am interested in buying the Sealy Plush Mattress you have listed. What are the dimensions on the mattress?
Seller: This twin size mattress is 38" wide and 75" long.
Buyer: Perfect. Why are you selling the mattress?
Seller: It was my child's bed, but he's outgrown it! We used it for about two and a half years, but it was covered with protective waterproof sheets, so it is still in excellent shape.
Buyer: Well, my husband and I are new foster parents. We have almost everything ready, but are still looking for a mattress. I think this would be a good fit and complete the room for the kiddos. Are you willing to take $100 for the mattress?
Seller: Congratulations to you and your husband! $100 seems like a fair deal to me.
Buyer: Thank you so much. I am submitting the offer right now. We appreciate your help!
Seller: Thank you!
