EPHEDORA Bed Bridge Twin XL to King Converter Kit - Mattress Extender Set to Fill in Gap - Memory Foam Filler Pad and Connector Strap - for Guest and Family Room (Twin XL to King (Bamboo) 12"x80")

It really works great! I wasn’t sure if the strap would stay in place but it has worked so well since I put it on my son’s twin beds. Along with purchasing a king size mattress pad, I installed the twin to king insert and now his bed is actually more comfortable than mine. No more of the annoying wedge between each bed, the insert stays perfectly in place and I can move the 2 beds as one bed when I’m making his bed in the mornings.Great item, would definitely purchase again if necessary.The wedge is very soft and cushioned, with adding the mattress pillow top protector, there’s no uneven gap in the twin - to king bed at all.Would highly recommend

This product was just what we needed and works well for us. Thank-you

A mí sí me gustó el producto, al principio se ve como mal hecho, ya puesto no queda tan justo pero mis colchones no tienen tanta separación, al final si se nota que está pero es muy cómodo, al menos para mis colchones quedó muy bien. Si lo recomiendo

A bit of a lump in the middle unfortunately. Otherwise good.

Used this to join 2 twin XL beds (36"x80" mattresses) to make a king sized bed. PROs: This gap filler was sized exactly for this job, appears well constructed to avoid having the foam bunch or curl, and the cinch strap held all components in place very well. CONs: was very tightly packaged, crushing the 3" foam wedge that acts a the gap filler between the mattresses. This wedge did not properly expand, even after 3 nights of use. This created an uneven and significant rise in the center of the bed. Though the foam is soft and will compress when laid upon, its presence is still noticeable. The sewn edge beading that helps the product to keep its shape is also easily felt under the sheets. We layered 2 open twin XL sleeping bags over the mattresses and under the sheet to reduce these issues with acceptable results.
