Yes, you can place the ladder on either side of the bed (left or right).

Please note that we recommend for our Camaflexi twin beds a standard twin size mattress (i.e. +/- 39" x 75") not exceed over 9".

NOTE; The weight limit for our Camaflexi beds (platforms, low lofts, high lofts or bunk beds) is 650 lbs distributed evenly each bed. Although when weight load was tested by independent laboratory the weight limit actually exceeded 800 lbs and remained intact
