after reading several threads from different websites i really dont feel confident in having a steel bed frame because of all the work that has to be done, such as steel has to be milled and flat as possible for the linear rails to lay down perfect and much more.

as for aluminium i know its costly but is there anything to look out for when bolting together and fitting linear rails? are aluminium profiles already zero tolerance as long as the beds been leveled?

cheers
