Hi Lucy,
 
Thank you for your enquiry. We have had sourcing difficulties of the gas struts required to lift our heavy mattresses (due to the amount of upholstery we use) and we have had to discontinue them for the time being.
 
Any base above a single size will come in two parts, either split north to south or east to west to allow for getting them upstairs and to the room of choice.
 
I hope this is helpful and if you would like any further information please do not hesitate to contact the office on 0161 437 4419.
 
Kind Regards
Michaela Long
