Types of Bunk Beds
Now that you know the bunk bed mattress dimensions, let us look at the different types of bunk beds.
Standard
Standard bunk bed frames are fit for holding a twin mattress. They feature one bunk directly above the other.
Some standard bunk beds have only the upper bunk. Thus, you get a lot of storage space below your bed.
Triple
In triple bunk beds, three beds are stacked on top of each other. Thus, you need a high ceiling to fit a triple bunk bed in your room. Sometimes, the middle bunk may be placed horizontally at a 90 degree angle.
Triple Loft
Triple loft bunk beds have the two top bunks facing each other at a 90- degree angle. And the bottom bunk is situated vertically below them. Thus, you also get some storage space for drawers and shelves.
Shorty
Shorty bunk beds are both shorter and narrower than a standard bunk bed. Thus, they are fit for tiny bedrooms. However, it is difficult for tall sleepers to sleep on them. You can use them in your children’s bedroom.
Trundle
A trundle bunk bed comes with two standard bunk beds. The bottom bunk has a drawer that slides out to form a bed. You can raise this bed to the same height as the bottom bunk.
L-Shaped
An L-shaped bunk bed has two bunks connected to each other at a 90-degree angle, forming an L. The space of the bottom bunk is occupied by drawers and bookshelves. Thus, it is a perfect arrangement in modern-day apartments where there is a space crunch.
Futon
Futon bunk beds have only the top bunk. And in place of the bottom bunk, there is a futon.
You can fold up the futon to serve as a couch during the day. It can be a perfect arrangement if you have guests at home.
RV
You will find RV bunk beds inside RVs, campers, and motor homes. They are just like a standard bunk bed. The only difference is that they are built into the vehicles instead of being separate bed frames.
How to Choose the Right Mattress for Bunk Beds?
Now that you know the bunk bed mattress dimensions, you might wonder how to choose the perfect mattress for your bunk bed. Here are some things to consider while buying your mattress.
Weight
Always choose a lightweight mattress for the top bunk. Putting a heavy mattress there will pose a safety risk for both sleepers.
It is better to check the weight carrying capacity off your bunk bed before buying the mattress.
Height
Choose a low profile mattress for the top bunk. The ideal bunk bed mattress thickness is around 8 inches. Make sure your mattress is not higher than the guard rails as that can pose a safety risk.
Quiet Mattress
What if the other sleeper tosses and turns a lot while sleeping? The noise will disrupt your sleep. Choosing a foam mattress will ensure there is minimum noise and you will sleep in peace.
Final Word
Now that you know everything about bunk bed mattress size, it’s time to pick up the perfect one for your bunk bed. Choosing the right size mattress will ensure you get sound sleep at night.
