    • Science of Sleep KingMaker 2-Inch Twin Bed Connect
      Verified Purchase

      We really like this product. Here's why: The foam used for the connection wedge between the two twins is noticeably firmer/more dense than a "Kingmaker" product made by a different manufacturer that was good too but not as good. With the Science of Sleep Kingmaker there less sag or depression at the seam of the two twins and thus more comfort. Also helpful when converting two twins to a king are a quality king mattress pad that has good stretch attachment material and a perimeter strap (around the twins) which helps to keep any slipping apart at the seam to a minimum if at all. Having the option to turn twins into comfortable kings and back again (e.g. using a trundle, daybed bed or two independent twins) increases the options we have in several rooms in our home when friends or family come to visit.

      We made a standard king out of 2 twin bed . This substantial pad bridged the gap between the beds and created a comfortable sleeping surface, with no visible sag or bump in the middle!

    • Looks nice, bulky to store
      Verified Purchase

      The middle connector that should slide down between twin beds pops up and is a bit lumpy but is more comfortable than using an air bed. Nice quality material, but would recommend adding a bed topper for best comfort. I bought a big box to store it in as it does not fold up to store.

      Very happy with the results of converting split king (twin mattresses) into a full king. Sleeps great with no detection of split between the two beds.

    • That was easy
      Verified Purchase

      We read that other mattress connector get all knotted up so we were a little concerned. But we didn't want to spend the money on an entire bed when we had "inherited" two brand new single beds. The secret was to buy a mattress topper, I think. We don't even notice that it's two bed put together. We're thrilled to death!

      Verified Purchase

      Great product so happy I found it. I had bought a new sleep number bed, split king, didn't think the gap in between would bother me. but the mattresses would slowly moved apart. This makes a huge difference. Everything stays together now. Can't even tell it a split king now. I would definitely recommend this item to anyone looking for the answer to that ever widening, cuddle separating gap.

    • Not what i expected
      Verified Purchase

      This product was not represented well on the web site. The filler between the beds was as expected but the ripple surface of the pad was a surprise. I would not have ordered it had I known this was the texture of the sleeping surface.

      • A:

        because I new bed

      • A:

        I have guests coming in July, for 3 weeks and I have two single beds I want to make as a King Bed as comfortable for them as possible. despite the mixed reviews on the center connector clumping up, I believe, in One review with an additional purchase of a king bed cover pad or the overlay will do the trick. I can't wait to start making it all come together.

      • A:

        I have arthritis and it's easier to move two twin mattress than one king mattress. So I just bought two twin bed frames and two twin mattresses and will use this connect them to make a king size bed that will be easy to take apart and move.

      • A:

        We are putting two twins together no needed something to hold them that was washable. This fit the bill!

        Thought I'd try it and if it doesn't work - I'll send it back.
