This design eliminates the weakest point in the majority of stretchers. By adding an extra vertical gusset leg the X cross bars have greatly increased support and won't bend. Previously regardless of brand of stretcher or weight of user if you sat on the edge of the stretcher and especially if you were directly over the legs, the Cross struts would bend or break.
The Sundowner stretchers are rated to 170kg and we've seen them put 200kg of cement on them during testing. They come in an XL and Titan, which is the biggest single stretcher on the market. They are super quick to put up and very comfortable.
We highly recommend this stretcher.
