Well designed and stable
This design is used by a number of retailers and has worked well. My wife is both short in stature and has limited mobility so I have two of these. One in the house and one in the car. Extremely stable and light weight and stores quickly and easily.  The yellow tape helps to see it in low light levels which is also a help if you have a bed that is higher than the door of you van.
