Hi Paul.

Do you mean using two steel frame beds as separate beds and being able to join them together if required?

If so then the answer is no...

Unless, the frames are completely 'square' without any kind of protrusions to prevent them being butted up to each other.

Also the slats / support cannot be in a recess, that means the mattress is virtually level with the edge of the frame, or else there will be no way the mattresses are able to be zipped together.

Please give more detail.

Kind Regards Gary
