They also offer advantages in space for families with smaller rooms or ceilings that are lower. Be sure to select the mattress that is safe to fit over the top bunk's guard rails. Heavy sleepers typically prefer mattresses that are firmer to ensure their spines are aligned, whereas lighter sleepers like soft beds that ease pressure points. Size Bunk mattresses are available in various sizes to fit different needs and living areas. The size of the mattress you select is dependent on the number of persons who will be sleeping in the bunk, and whether the bottom bed is designed to accommodate either a daybed or trundle as well. In general, you should stay clear of innerspring mattresses that require the use of a box spring because these tend to be heavier than other types and can create a squeaky bunk bed. You should consider a smaller bed for the top bunk, if your bunk bed has one. This will keep people from feeling cramped on the upper part of the bed. Mattresses that are less than 6 inches thick are also recommended for the top bunk as they fit comfortably within the railings that guard it and reduce the chance of falling off the bed during the night. For the bottom bunk, you can select a mattress that is full and fits two sleepers or opt for twin XL mattresses. The XL mattress is 5 inches longer than a regular size mattress and is best for teenagers or adults. To ensure safety, the bottom bunk should be fitted with a sturdy bunk guard to avoid accidents. This guard is usually a steel frame that sits securely under the mattress, so you can be sure that your child will not be able to get out of bed at night. The guard should not be extended higher than the top bunk bed mattress, as this could be a risk of death by suffocation. The
