Asatdd Bed Bridge Twin Size to King Size Bed | Waterproof Bed Split Filler, Twin Size to King Size Bed Converter, 75" x 12"

It took a while for it to stay flat, but I put some weight at each end and after just a few hours it was fine. The filler is not noticeable when a mattress pad is placed over it. It's nice not to have that gap.

This does the trick to bridge the gap in the twin mattresses of my daybed when I set it up as a king bed. Although it stays in place, if you are a wild sleeper, you may want to use a mattress cover that keeps the bridge protected from kicking it out of place. It feels soft and durable and I bought a 2nd one for my new sofa-bed

Works great no more falling in the crack

Fills the gap nicely. Is noticeable when in the bed. We use this to turn our day bed wit trundle into a king bed. It’s only been used a few times. After a year the material is peeling up. It’s like the soft platic of a mattress pad. Overall a decent product but I’ll get one made with higher quality material.

The middle piece is to small on line it shows the piece that goes between the beds bigger this will not stay in place very disappointed

Perfect

Absolutely love this it has made a huge difference 👏

Although it did cover the gap between the beds, it still left a bump in the middle. I will have to replace the mattress with a larger one
