Do all king (eastern) latex mattresses necessarily come split in two pieces

Hi gus1gus1,

There are many king size mattresses that have individual layers that come in one piece rather than having a “split” construction. One piece layers are probably more common than having split layers which is an option that isn’t offered by most manufacturers in the industry.

With most manufacturers that offer this they would be individual so that one side or the other could be exchanged but it can vary with each manufacturer. There is more about the pros and cons of split layering in post #2 here.
