Awesome sturdy solid wood bed for my 10 year old and 5 year old. I made them assemble it. My 5 year old mostly mixed all the pieces up and my 10 year old had to take a few pieces apart and put them back together because he put things in backward.
But the look of satisfaction on both of their faces when they finished was awesome. Great bed, space saving, simple design, easy to put together, (a 10 year old dude.) love it. 
I will say this, we have carpet and I made a handle for the trundle so my 5 year old can pull the bed out easier. Not a complaint my 5 year old just wants to do everything by themself.
