We have a day bed with trundle. The day bed is extra tall, I use bed risers under the legs. The trundle has a frame that pops up to a regular bed height. A day bed is harder to make than a regular bed but I only have to make the bed if someone stays and that's only a few times a year. We had a double but that didn't leave much room for any thing else. Now there's plenty of room for a home office. Before I had a design table I used the bed as a design space. The quilt hangs down because of the extra height and I could pin blocks to it.
