I bought this last year after nearly fainting from exhaustion in the check out queue at Lidl and fighting back tears as I trudged home in a fog of misery and pain. It's more expensive than most shopping trolleys that you can sit on, but I needed the arm rests because my legs aren't strong enough to stand without help.
Walk and rest trolley with armrests
I weighed 120 kg when I bought it, so was looking for a very sturdy trolley that wouldn't tip when I rested my entire weight on it. One of my legs is very untrustworthy, and can give out without any warning, but being able to push the trolley in front of me, leaning all my weight on the handle has allowed me to practice walking safely. My gait has improved because I can now subject my dodgy leg to the full range of proper walking motions (instead of having it splayed out to the side and dragged along behind me), I sometimes feel it giving way, but don't fall because the trolley keeps me safely upright.
The best thing is that when I feel exhausted, and as if I can't possibly take another step, I don't have to look around desperately for a bench or something I can lean on. I can just set the brakes on the trolley, lower myself onto the seat and relax.
When there's a long queue at check out and I'm already trembling with exhaustion I no longer battle with tears and fear collapsing. The only downside is that, after I've packed my shopping into the bag and lowered myself onto the seat for a lovely rest, all kinds of people that I've never seen before feel compelled to approach and strike up conversations, telling me about their own health challenges, and asking where I got the trolley from. I even had one elderly gent start to unbutton his shirt to show me his heart operation scar.
So although it was expensive I haven't regretted buying it for an instant. I just wish I'd bought it earlier. Knowing that I can always stop for a rest gives me confidence to walk places I wouldn't otherwise dare to go. It's lighter and easier to fold and pack than a mobility scooter, and walking while resting most of my weight on the trolley has strengthened my leg muscles that were getting atrophied from lack of use.
I was so limited in what I could do and where I could go before, never being sure that I'd be able to walk from the car park to a venue, never mind being able walk around looking at stuff once I'd got there, and trying to find somewhere to sit down when the few available seats are all taken. It's lovely to have my own chair/walker, especially with a picnic packed under the seat.
