VEVOR Garden Kneeler and Seat, 10" EVA Wide Pad, 330 lbs Load Capacity Foldable Garden Stool, Kneeling Bench for Gardening with Tool Bag, Gifts for Women, Grandparents, Seniors, Mom and Dad

Maybe. It’s held on with screws.

Yes. But you would have to reattach it.

I am not sure as its at our camper

Yes

I have a cheaper version with a thinner pad & it works for what I need it for...but I bought three for three of my daughters & bought the thicker pads due to knee fatigue....you'll have to contact the mfg to fond if the pads are replaceable, I'd give the Velor 5 stars.....

It is securely attached for sitting and carrying either folded or open. You may note the 3 screws down each side between the kneeling and sitting pads both of which are quite firm and overhang the bar with the 3 screws. It is not obvious to me that one could remove the pads even after removing those 6 screws nor why one might want to?

looks like it can be very easy to replace. Not sure

Very handy for folks like myself who find getting down and up from a kneeling position increasingly challenging.

I don’t think so. It’s a hefty pad and my kneeler is old now and it’s great!
