When looking for a place to sleep, many people choose a pop-up trundle bed. This type of bed is typically smaller in size than a traditional bed, making it ideal for small spaces. Additionally, the trundle bed can be pulled out from underneath the main bed when extra sleeping space is needed. One question that often comes up with regards to pop-up trundle beds is how much weight they can hold. The good news is that most pop-up trundle beds have a weight capacity of around 400 pounds. This means that most people should be able to comfortably sleep on them without having to worry about the bed collapsing. That said, it's always important to check the weight capacity of any pop-up trundle bed before purchasing it to make sure it will be able to accommodate your needs.
