What is a bed?
A bed is a piece of furniture which is used as a place to sleep, relax, or engage in sexual activities. Most modern beds consist of a soft, cushioned mattress on a bed frame, the mattress resting either on a solid base, often wood slats, or a sprung base. Wikipedia.
Average height
around two feet
For most, the standard bed frame height should be knee-level, about 16-24 inches off the group. At this distance, people can generally put both feet firmly on the ground and push off the bed with their knees bent, making the average bed height around two feet.
Signs
Other signs that you have bedbugs include: Blood stains on your sheets or pillowcases. Dark or rusty spots of bedbug excrement on sheets and mattresses, bed clothes, and walls. Bedbug fecal spots, egg shells, or shed skins in areas where bedbugs hide.
