At first, I want to emphasize that my two children and I love this bunk bed so much.Have better need two people to cooperate, one for installation , the other one for holding them together. It takes four hours to finish it, thus be patient please. You need some one who can use electric screw diver well. This is my husband first time install the bunk bed, but he often helps others to install metal platform bed frame. This bunk bed have a very good looking, I really like this color and painting so much. I want to emphasize that the painting with no any bad smell, it is very good for health. In addition, I still have something very important to emphasize, cause by the bed slate. The bed slate (with no painting they are made of natural wood )always keep volatilizing at beginning 20 days. I can’t remember how many bed slates for total. I think it is about 20 pieces. The number of 20 bed slates means will have much more natural smell keep volatilizing. It is natural smell, thus it is nontoxic. Like flowers, many people like it, but many people have allergy to it. My nose have allergy to it. My both children are fine. I suggest you could buy it in early time, it takes about two weeks to deliver to you. You should consider to buy early cause by these two reasons. Then, I have one more important thing to emphasize. You had better to put your mattress to your down bed firstly before you install stepladder. I found a big problem to put mattress on the down bed after I finish installation. I can’t put it on the bed if I am not smart. You need a little skill to put your mattress on the bed. My mattress only 4 inches, one side is hard one, one side is soft one. That means it can’t be bent. I should put it from the bed side with no stepladder and lift it up to enough height, then, will have enough space for the length of mattress. My mattress is standard full size. You will easily understand why it doesn’t have enough space to match the length when you put the mattress. I will show the picture to point it out to right position of height. I hope this had better to be noticed on the guiding paper.Then, I want to say the design for installation is very professional .That means it is not hard to install it and every one could do it. I should say the designer is very professional and made everything to be simple and clear. Even the package of the bed is very standard with high quality and level, only two simple and solid package. But please take the time and be Patient. Finally, I highly recommend this bunk bed. I also suggest you to buy bunk bed like this one because up bed and down are the same size( both of them are full size). Even my children one is three, the other is four. Enough space is better for children.
