This Daybed with Trundle is GORGEOUS! I waited for over a month for this to come back in stock on Wayfair and I am so glad I did. It arrived in three separate boxes with detailed instructions for easy assembly. I purchased an 8" Linenspa twin mattress for the trundle and it was a snug fit when stored beneath the daybed. For the daybed, I purchased an 8" Linenspa twin xl mattress and, while it did fit perfectly from end to end with no gaps, it does make tucking a comforter in around the edges a bit of a tight squeeze. I would recommend a twin xl if you plan to use this primarily as a couch/seating area, and possibly just a twin if you plan to use this as a bed with a thick comforter on top. Overall, I am extremely pleased with the look, quality, and value of this purchase!
