I got the Quinn Twin size bed in gray for my 4 year old for his first big boy bed and he absolutely loves it! The headed is very high, I would say almost 5 feet. I like that the back has a zipper which for me is great to hold blanket so it's easy to store. It does sit lower to the ground which is good for my son. It says it does not require a box spring but I will eventually get one due to the gap in the back between the mattress and headboard. His pillows start to fall between the space. It was fairly easy to put together. I am a 5 ft woman and I did it by myself within 45 minutes. The instructions can be a tad bit confusing since the numbers are not in order on some pages. One thing I love about building items is having extra screws which this one had! I would definitely recommend this bed. It is very sturdy and nice on the eyes!
