    You might find something on YouTube. But the only way I can think of making this happen was if the bed frame was in a corner and to pad that side by the wall.

    Buy a king? You can have mistresses custom made. Call local mattress companies and get a price. We have one here named Bowels Mattress. Not as expensive as I thought. Have to have them made sometimes for antique beds.

    Only if you build a big box around the bed and then fill in the gap with foam. Since there are always sales going on at all the mattress selling franchises, you can buy a king sized bed for cheap.

    Not that I'm aware of...

  • I don't know about making a matress wider, but we did recently buy a memory foam mattress for my parents' motor home, which has a funky-shaped bed. We cut the corner off the mattress to make it fit. But read reviews on the mattresses- some are made of fiberglass and when you open up the case they'll cause all kinds of problems. You'll see what I mean if you start reading foam mattress reviews. Good luck!

    I have never heard of anybody doing this but I think it could be done if you think outside the box. Perhaps a sofa cushion could be cut to size and attached to a board with spray adhesive.

    Thank you I bet that might work.

    No not really. You could try buying dense foam and putting a strip down each side and securing it with Gaffer tPE, AND THEN PLACING THE WHOLE MATTRESS INSIDE A mATTESS COVER. tHAT MIGHT WORK FOR YOU!
