When most people consider furnishing an adult guest room or outfitting a large housing facility such as a dorm, boarding house, or military housing unit, their first thoughts are of triple bunk beds. But when you have a little bit of extra space, with an average ceiling height of fifteen feet or more, and you've got a good-sized room to work with, you can really use that vertical space for your benefit and fit in a few additional beds at the same time. This is especially true if you already have one bed and want a second to be closer to the bathroom or the kitchen.
A triple bed is an excellent addition to any adult bedroom as explained at http://choicemart.co.uk/furniture/bedroom/beds/childrens-beds/bunk-beds/triple-bunk-beds/. These beds come in all different sizes and shapes, and all have their own set of advantages and disadvantages. However, when you add in three beds in a row, it provides a very neat and orderly look in your bedroom, while providing extra sleeping space for guests and roommates who may stay over.
Double beds offer more convenience than single beds, and they can often be installed on the same side as a larger bed. The advantage here is that you only have to put in the top one bunk, rather than having to install two beds. But double beds also have their disadvantages. For example, they tend to be harder to get into and out of the way, and they can be difficult to convert into singles, unless you are particularly handy with tools.
If you want more space in your bedroom, then a twin bed will give you more options. However, these types of beds are not for the adventurous types, as the fact is that they are much heavier than other types of bed. It's also a lot harder to convert a twin to a single, so it's not a very convenient option if you need extra storage space for toys, clothes, etc. Also, because of their size, twin beds can make a room look too crowded, which is definitely not what you want to accomplish.
Another disadvantage of twin beds is that they can take up a lot of overhead space. They are usually the least attractive option, since they take up a lot of space in the bedroom. If you need extra storage space for things such as dressers and chests, then a chest of drawers would be a better option.
Bunk beds, as the name suggests, are the best choice for accommodating three beds in a row. In many cases, they can be stacked together on top of each other to create a much bigger area, so that you don't have to worry about limited space.
