Zip and link bed

Unfortunately space between bedside cabinets is limited and is only 179 cm (5' 10 1/2") However, we feel we would prefer a zip and link to eliminate disturbance between each other through the night. It looks we would have to go for 5 foot option of 2 x 2' 6" single beds, which would be OK for us as we are quite small people. We are currently sleeping on a double mattress and divan of 4' 6" and we 5' 4" and 5' 2" and weigh 10st and 8st respectively. Could you please advise on our options, price would not be an issue.
