The biggest problem with bunk beds may be that it makes your bedroom feel very crowded due to the sheer size of the bed. If you have a small room the effect is multiplied, however if you have a large room the size of the bunk will not have much of an effect. In my experience, when sleeping on the top bunk, it can be very painful to walk down the stairs in the morning when the muscles are stiff and seem to have no energy-producing capacity. You get used to it after a couple of months but it’s not very pleasant to have to go down some vertical stairs first thing in the morning.

Another factor to consider is the lack of living space it creates. The bottom bunk usually doesn’t allow for upright sitting because the top bunk is too low and in the way. There are frames that come with the ability to convert the bottom mattress into a sofa-like seating area, but it’s an add-on that costs extra money. Sitting on the top bunk is also inconvenient as there isn’t much to do there.

Things like watching TV and playing computer games from up there can be a bit awkward. A single bed, on the other hand, is a great sleeping area in almost any room, especially for things like watching TV and playing video games.
