As you know, the original Carver sleep sofa has to be moved for access to the port engine. That sofa was just too much for me to handle. I would have to partially disassemble it to move it when doing maintenance. Plus after 20 years it was showing some wear. I would have loved simply purchasing a sectional unit, but could not find one the right size. I decided to build a sectional. No, I have never built furniture before. I studied some sectionals online, example: https://www.homereserve.com/?show=secti ... WwQAvD_BwE
I started back in January. The wood frame is 1/2 exterior plywood. I made the legs out of poplar (which stained very close to the teak interior). There is more storage than with the original, and I left the bottom out of the 'L' so its easy to get to the gas valves. One thing I would do differently, I bought firm polyfoam from Walmart (online). I would order regular density, because to me, its a little too firm. If anyone wants the dimensions and rough diagram, just email to jerrygaggini@aol.com
