  • Do not buy!
    Verified Purchase

    Rather than the appearance on the site, the product is a piece of plywood cut in strips. What a disappointment for my first purchase here

    Verified Purchase

    This looks nothing like the picture upon arival. Didn't know I needed to buy a frame as well...comes as 5 boards (which are unfinished). Says "brown" finish in specs....but there is no finish whatsoever. The boards do not sit even over the frame. Can't imagine how this would be comfortable. Don't buy this.

Questions & Answers

  • Q:

    "Can I see an assembled demo of this bed frame any where in San Francisco ?"

    • A:

      Hello jitenoswal1! We do apologize, we do not have any demos available. Thanks for shopping with us! -Amanda P

  • Q:

    "Are the slats tongue and groove and lock into each other so they don't slip around? Are the edges rounded to prevent injury if the mattress slides a bit? What is your return policy?"

    • A:

      Hello maryk9138, thank you for your inquiry! No, they are not attached together, they are 5 slats and you simply lay them down next to each other. Yes, the sides are rounded.
