2-in-1 Bed Bridge Twin to King with Attached Sheet - Twin Bed Connector to Make a King - Split King Gap Filer - Mattress Wedge Gap Filler - Twin to King Bed Converter - Mattress Gap Filler King Bed

It makes two of my beds into one! It does kind of leave a... bump? But it's more visible than it is tactile. I don't feel it while I sleep, but I also put another thick bed cover on top, which is helping. It can be a bit hard to get it into place if it winds up getting out of it while setting up the bed, got to separate the beds and shimmy them back in and wonder if it's even working at all until you go "Good enough."

This item changed our sleeping life. It is an amazing product. A friend of mine told me about the wedges and I started doing my own review. I did not buy the one she sent me because it was just too complicated. This one. I’m telling you it was an absolute perfect fit. I will buy several more.

Very comfortable and is easy to fit

Exactly what I needed. We have been using this for months and although there’s a slight hump the two mattresses now stay together and this product fills the gap between the two. Great solution and reasonably priced.

Great works fine just no longer needed because I decided to change the bed instead. Definitely doesn't make it into a king because you can still feel the gap a little but this is the best product out there to make the gap feel better. It stays in place and honestly it's the only thing that makes it easy, sturdier and comfortable. I would've kept it if I wasn't getting rid of the mattresses (they were cheap mattresses and are almost 8 years old, extremely overdue) make my back hurt
