After a lot of research, we’ve decided to go with a king-size mattress from Latex Mattress Factory using their natural wood foundation. We were able to try out latex from the same manufacturer in a store; we both liked the same Soft - Medium - Firm Dunlop layering of all the combinations we tried. If we have problems getting it, we will try for the same thing from SleepEZ. We may get an additional topper but we’re waiting to decide until we actually sleep on the bed awhile.
We haven’t decided yet what metal frame we should use to support the bed. We were considering the Knickerbocker “The Monster”, but this thread mentions that there’s a problem with sagging due to the screws being misplaced. Phoenix, do you know if the company ever responded to the poster who said the bed sits on the screws and not on the bedframe?
