The stairs at my apartment complex works fine with this cart. If your using it for lighter loads like laundry (going up the stairs), it's much easier versus hauling heavier loads like groceries (like we do via 2-3 stacked InstaCrates w/Bungee cords). Our carport is quite a distance from our 2nd story apartment so we consider it a godsend, however keep in mind that lighter or heavier loads will determine the labor factor. With laundry, I can use just 1 arm on the handle while traveling up the stairs facing forward. During grocery runs while I'm alone, I must use 2 arms when hauling a heavy load up the flight of stairs facing down the flight (*Tip* = for heavy loads, 2 people lifting..one on each end is much faster/safer in either direction) which I prefer over multiple trips between points A & B. For safety reasons, when descending alone, I'd recommend only lighter loads since the resistance you must provide will prevent the wheels from dropping violently between steps. I've seen comments that it leaves visible marks on lightly colored floor surfaces since the wheels don't swivel (this is a design issue) so one can expect shorter wheel life in environments especially where narrow hallways with twists and turns are present. If you can envision a future model with a swivel feature and either a motorized stairclimber or a descending counterweight system, wouldn't that be the ultimate in convenience? Things typically improve over time but for now, I can anticipate the replacement costs for parts on this nifty item. I wish I could say the same for health deficiencies such as early onset arthritis, arm muscle pulls/cramps, and joint pain. Avoid the previous and get this for yourself & your family!
