Insieme Strap for Twin Beds, 33 ft Long Twin to King Bed Converter/Mattress Joining Strap with Adjustable Metal Buckle. Use to Combine Split Twins or Twin XL to King and Hold Mattresses Together

After extensive research, I'm glad I went this direction. Serves its purpose. Is secure for the two twins I made into a king for myself and my toddler. In order to get it the way I wanted it I had to tighten it in a way that cuts into the middle of the side of the beds so if that's not your thing I would say to be mindful of that but these beds are older and passed down from family so I don't mind being a bit more aggressive with them. Wrapped the excess by the latch and secured it with the mattress cover. It does what I need it to do and I think this company is use. I like the branding, etc.

I imagine this works with no issues. I actually do not know cause I sent it back 'cause another item I brought came with this item. Did not need 2.

We needed a long strap with clasping ability. This product served that purpose but it doesn’t stay tight for too long. I find it necessary to re-tighten the strap every 4-5 days. We do not use this product for what it is intended for but, I feel that a clasp should remain tighter for a little bit longer. I guess the argument could be made that it was not made to be used for anything but the intended purpose and that is why I gave a four rating and not a one.

Finally, a product that keeps the sheets in place. Thank you!

The product would be great if it actually stayed on the bed. I have to readjust the straps every single day.

We rented a house with two bedrooms for a month. One of the rooms had two twin beds. We were having a few guests that were married. This strap was AMAZING! Kept the beds together and never came apart all month long! Just be sure you pull it tight when you put it on and add king sheets! I know that we will use this for years to come!

We use this to sun h 2twins together and make a single king bed. This thing works great. I can pull the mattress in half with this strap and it would hold. So I had to back it off a bit and it’s been working great for a month now. We first used a Cheap plastic version and it was terrible. Not this one. It’s perfect and easy to use. I did it alone but another person would’ve helped since our bed is so big. But it only took me 5 minutes to install.

Works as advertised. Just wish it were wider--twice or more. The narrow strap twists easily and really cuts into the mattress, so it works best with mattresses that have a hard or firm side frame.
