My 4 year old kept asking for a bunk bed, so my wife and I went to the furniture store and saw we would be paying close to $1000 for a junkie bunk bed. We told him it cost too much and left it at that. Then he started bringing us pennies, dimes and all the change he could find to pay for the bed. So I found this website and decided to attempt to build him one. I started building it after work on Monday, continued for a few hours every evening and finished Saturday morning. It turned out amazing, and both the boys love it. It is extremely sturdy, and will last beyond my lifetime. It's just a good quality design. Total Cost was about $300. Not bad for what we would have been paying for a lesser quality bed. Changes I made: I added the railing on the front of the upper bed to match the headboards and railing on the back side because my wife is a worrier. I also designed and built the stairway and bolted it to the lower bed. I am no professional carpenter, a novice at best. Most people with a little carpentry knowledge can build this. Thanks Ana, we all love it!
