BEDIA 12Inch Bed Bridge Twin XL to King Converter Kit with Strap | Mattress Connector for Bed | Non-Slip | Storage Bag Included (12x80Inch)

Q: Will this work with 2 standard queen mattresses?

I see no reason why the bridge itself between the mattresses would not work. I do not know the length of the strap that secures the mattresses together. It may be listed in the detail section of the advertisement it may be a direct manufacturer question. As I recall it is a small start-up family company so you should be able to get a quick answer on that. The bridge no problem, the strap I don't know the answer I see no reason why the bridge itself between the mattresses would not work. I do not know the length of the strap that binds the batting together. Mine is currently disassembled so I cannot find it to measure for you

Q: What is actual measurement of the the XL product? Not packaging.

I’m not sure with out take apart our bed, but it fits well on a pair of twin xl’s to make them one bed.

Q: Does this work for a california king spit bed?

I think it would work better for a California King. I used it for 2 twin beds and there was quite a gap because the individual bed frames keep the mattresses apart. I ended up stuffing a rolled blanket between (the gap was probably 4-5 inches. But this invention works great to bridge the gap!
