There is an elevation adjustment knob. We are very well pleased with this item.

Yes, not a knob so to speak, but a clamp. These rails are so tight and precise to begin with. But yes, once you have them in the location you desire, you clamp/close the side levers.

the adjustable spring knob is the front so that you can adjust the height at any time. thanks

I do think that lever is to keep the steps from mashing little fingers. I may have it on backwards but it does keep the steps in.place when closed up. That's my best guess

I know what you mean--I had to call the company to find out how to do it. On each side of the walker there is a black lever that you turn either clockwise or counter clockwise to loosen and tighten and this adjusts the handles. Good luck.

I don't think there is a way to adjust them. When I in stalled them. They are in a prefixed postion.

No problem. Lever is almost straight up in the hot position. Don't use it much either.

Yes. You could switch them around if you want - they're closed systems and the levers have bilateral symmetry.

Yes! There is a rolling lever that helps with the adjustments on thickness.

you should be able to twist/rotate the quick release to adjust how far it clamps when you push the lever in.

Yes each shelve has 3 sets of holes for adjustments. It's approx 2 inches of adjustability.

There are three levers. The first, closest to your knees raises the seat up or down. The middle tilts the seat forward or back. The rear lever tilts the back forward or back. Each lever has a drawing demonstrating what it does.

There is an adjustment valve on the handle. It allows for pressure control also.

The bottom lever on the side is the temperature control. Pressing in the knob on the lever allows you to adjust from the standard setting to warmer or colder.

There is only one adjustment, as far as I can see: the height, which works by pulling up on the lever with the concave disk handle. To lower the seat, you need to be sitting on it (or applying downward pressure). I don't see what that big knob under the seat does.

there is a knob to turn to loosen and tighten - it is adjustable (took a few tries to figure it out).
