Choosing the Right Mattress Size For Your Space
It can be challenging to narrow down which mattress size would be best for your space. When choosing a mattress size, it's important to make sure the mattress will properly fit inside your bedroom.
Ideally, you need at least 2 feet of free space around both sides of the mattress and at the foot, although 3 feet is more comfortable. This additional space will offer more ease in making your bed, make the room more visually appealing, and prevent other furniture from hitting the mattress.
How to Measure Your Room For A Mattress
When considering which mattress would be best for your space, you should first measure the room. Having a big bed will offer the most space for sleepers but it could make your room feel cramped. This is why it's important to assess your space to see what size mattress it can comfortably fit.
You should first write down the dimensions of the bed frame your mattress will rest on. If there is a headboard and footboard it's important to account for the additional space. Use painter’s tape to mark the dimensions of the bedframe on your floor where you intend on placing the bed. This allows you to get a better idea of how much room the new bed will take up and if it'll fit with your other furniture.
