Buying bunk beds is a popular decision nowadays, especially among families with multiple children and some extra bedrooms. One of the main reasons why people like to use them is they can actually save you quite a lot of room on the ground. When you have bunk beds, you'll usually get two beds on top of just one. You can even save more space by having extra drawers under the bed on which you can store extra stuff. Some models also have trundle beds built underneath, so you can easily transfer your belongings from your bed onto the bed.
However, buying such bunk beds requires some careful consideration. If you have very young kids - below four years old - you should be wary of their safety. They may be more prone to injury than other kids because they are not yet used to sleeping alone in a room on their own. Make sure you buy these beds with rails or bars at the bottom to prevent them from rolling off the bed. This can be particularly hazardous if you have two kids sharing a bed.

Another factor to consider when buying good bunk beds is whether or not you'd prefer to assemble or buy them readymade. The latter option is obviously the more expensive one, but many parents choose this option because it allows them to assemble the beds themselves. It's definitely an easier option, but you should also bear in mind that kids love to be involved in all kinds of activities, and may not want to just sit in one corner of the bed while you assemble it for themselves. It would be a much better experience if you let them in on the whole assembling process so that they get a hands-on involvement in things - even if this means that they have to move something halfway through the process.
Once you've decided what kind of beds you're interested in buying, it's time to consider what kind of loft bed to buy. Naturally, most people choose a twin over a full size, simply because a twin bed offers more sleeping space. However, you should know that there are also twin loft beds that offer only a single side. These are just as comfortable, but obviously they won't provide as much sleeping space as a full sized bed will. Again, it's a personal choice as to what you choose - most people seem to agree that buying bunk beds that have a twin on top is the best choice.
Next, you need to think about the style of your kid's bedroom. If your kids are young, then perhaps a l-shaped bunk bed will be best suited to their room. These come in a variety of shapes and sizes, including various degrees of "l" slant. A l-shaped bunk bed gives the kids room to spread out, which is important as you don't want them sleeping on your bed, and spreading out on your furniture would not be ideal either.
If you're buying l-shaped bunk beds for older children, then you can choose from various different styles. There are ones with a ladder on the bottom side, or you could go with a ladder that runs up to the top bed. However, keep in mind that a ladder on the bottom side of a bed is pretty dangerous, so if you don't have a strong kid, make sure to avoid this option - better for your own sake that it is for yours. Finally, you need to think about whether you want a slide or not on the top bed. Slides come in a variety of different designs, but all have the same function - they allow easier movement between beds.
