So easy to set up! It took me 2 hours to do it myself although I did ask my kid to help me hold the frame for one section. The bunk is not as “big” as I thought it would be and with 6 inch mattresses, there is plenty of headroom for my kids who are 6 and under. Taking sheets on and off the mattresses are easy as long as you have a step stool. My kids love bunking together and because this frame is such a space saver, they now play in their room! The only one note is that the bed is pretty squeaky. Not sure how to prevent that but the kids don’t seem to notice it.
