Best bed set up for a guest room

Hello. Can I echo others - superbly helpful website, found by chance while researching a new bed for our guest room. We want the room to be flexible, able to sleep a couple or to sleep two of our grandsons. So we were thinking of a zip and link bed which would spend most of its time as a kingsize. Our grandsons are 7, 5, 4 and 18 months and so don't present a big challenge - yet, but we want it to be suitable for our sons and their wives for brief stays. I have looked at your Origins Pocket Reflex 1000 – KS Ziplink. This is not the cheapest but it offers better support. Are we on the right lines? I would order with 4 drawers to give us some storage too.
