Zip and link mattresses

We tried to purchase two zip and like mattresses from HYPOS/PREMIER Inn that we slept on at Premier Inn, We found that Hypnos did not make them
I am now researching for a suppliers. We already hav a divan base 200 by 150 wide although we are not adverse to purchasing a new divan base with draws to a maximum of 180 wide Due to our ages the deal would have to include removal of the old bed and installation of new (Hypnos do this ).Could you please advise Thank you frnk
