i bought a bunk bed a few weeks ago. the instructions were meager, it weighed over 400 pounds and the expected time to assemble was 8 hours.
eureka sent two guys over and assembled the bed in a couple hours. they were friendly and obviously knew what they were doing. they bundled up the garbage and left my place in a fairly clean state.
booking with them was easy and they were accommodating with an unpredictable delivery schedule.
i suppose they're a touch expensive, but sometimes you just don't have the time or energy to diy. i'd recommend them to anybody.
