When I came South 44 years ago I got involved with a resto business where my partners lived on a farm and had only one vehicle indoor shop space, so we often had to lift on asphalt, gravel or grass. I made a few sets of jack stands that used 10x10x1/4" base plates (and one much larger set for trucks) that allowed for safe and stable work on soft ground. For the OP's purposes I mention that since many driveways are asphalt paved and ordinary sharp edged jack stands will sink badly on a hot day. One thing to leave damage on customer's driveway but another thing altogether to try to catch a car with your body when they sink and tip. BTW: on grass even with my jack stands we always place a wheel (preferably 2 stacked) under somewhere near working position as insurance. Working on potentially unstable surfaces is one thing, but working ALONE on them takes 10x the caution.
Another jack stand note: on my stands we often use only 2, making the car sit off level, so my solution is in a half-hole at top of 2" pipe out tube I make a pad with 3/4" round rod underneath so a car can sit off level with pad aligning with contact point. No height adjustment, but no reason one couldn't make something adjustable in similar fashion.
