For 2024, there are significant developments in the area of battery powered stair stretchers. Most notably, most manufacturers have shifted their focus to improving user comfort, safety, and ease of maneuverability. Some have introduced more robust restraint straps with quick-release buckles. Furthermore, they have integrated two stationary rear wheels that enable the stretcher to be moved over most surfaces with minimal effort. It's also worth mentioning that the maximum weight capacity has been ramped up to 350 lbs in some models.
