So I would carry it around then sit on it for weeding (sitting on the job lol)you can also get knee pads that you strap round your legs, or fit to knee pockets of your trousers, but a gardener's kneeler like that is what I use.
If your back is bad you can also get one with raised handles to help you get up (or turn it over for a seat). Mine has a small compartment for storing secateurs or other small items.
Not kneeling down is best.
There is a roofers back support which may help your bending...Actually my knees aren't hurting from kneeling it's more my back which is a problem and thought it better to start kneeling than bend over, then heard that hurts your knee. But kneeling on pads is the best way for your body, isn't it?
How u carry your kneel pad around when moving about? might attach mine to my belt
Hipflask, waccy baccy and iPod?Mine has a small compartment for storing secateurs or other small items.
Not as stupid and silly as you'd feel if in your 50's you were half-crippled and unable to work because your knees were shot.I felt stupid when I first put them on as they looked silly
