This is a really good set of bunkbeds. I bought these for my girls who are 8 and 12. They are very sturdy and with memory foam mattresses we bought from Great Offer Stock, my girls are very comfortable in them. We only have two complaints about the beds which are what lowered the rating. There are an enormous amount of parts. I believe my husband counted over 300. He also said the directions weren't the best, but he was able to get together ok. However, it took a long time. He had to stop twice and go back later to finish. My other complaint might be a plus for some. The railing on the top bunk goes all the way around without breaks where the ladders are. I am sure this is because this model has ladders at each end. This does make it more difficult for the child to get out of bed. My 8 year old was not comfortable with this in the beginning, but with practice is doing better.
