Im trying to lower my office chair?

If it's an old chair, it's possible that spinning the chair will raise or lower it.  Otherwise, it's possible the raise/lower lever has fallen off and you can order a new one of those (look on the bottom of the chair).  Or, it's possible that the chair cannot be adjusted.  (the knob is just a tension adjustment as you recline...it has nothing to do with raising or lowering the chair)

Dips.  Extend your legs out in front of you.  Support yourself on the edge of a chair.  And lower your body towards the floor.  Do 3 set of 8.  Work your way up to 3 sets of 20, and add weight to your lap.

Just get a piece of plastic sheeting..Suspend it off the ground 6 inches..Put a weight of some type in the middle, to form a downward cone..thats about it..You might also look it up in your Boy Scout Hand Book..its a good read.

Sitting posture in an office chair \nPosture is important for sitting in office chairs and at a workstation. Many of us spend hours in front of the computer, resulting in back pain or neck pain. Much of this pain may be avoided by a combination of:\n\nAdopting a user-friendly workstation by adjusting the office chair, computer and desk positioning \n\nModifying how we sit in office chairs\n\nTaking stretch breaks from sitting in office chairs or standing for long periods of time\n\nGuidelines for a comfortable workstation and office chair\nA consistent, comfortable workstation depends on where the computer screen is situated, where we place our feet and hands, the direction we look and the kind of office chair we use.\n\nFigure 3 provides a common sense, easily remembered approach to fitting a seated workstation to the individual worker. To make it work, begin, not with the office chair but with the work surface.\n\nChoose the surface height for the desk (standing, sitting or semi-seated) best for the task to be performed. Architects and draftsman may want a higher surface for drawing while computer entry work could be seated or standing, depending on the need to use other tools or references. \n\nAdjust the seat of the office chair so that the work surface is “elbow high.” Your fist should be able to pass easily behind your calf and in front of the seat edge to keep your legs from being pressed too hard and your feet from swelling. Two fingers should slip easily under your thigh. If not, use a couple of telephone books or a footrest to raise your knees level with your hips. The backrest of the office chair should push your low back forward slightly. \n\nFit the height of the computer screen. Sit comfortably in your newly adjusted office chair. Close your eyes and relax. Then, slowly reopen them. Where you first gaze as you open your eyes is the place to put the center of your screen. You can raise the height with books or a stand if needed. \n\nSee pics at \nhttp://www.spine-health.com/topics/cd/ergo/ergo03.html

Have you turned it over? If so try a piece of plywood underneath.  That should stop the sagging...it might be a little more firm though.  Otherwise...replace it!

Go on line for Yogan exercises.  One is to sit up straight in your chair and raise your legs to hip level.  Another is to put your hands together and place over your head toward your back.  Try to remember good posture at your desk.  Do exercises 4-5 times.

if you lay down on the floor in front of a 4-legged chair, so that your legs are in the seat of the chair (above your body of course) and hold the two legs of the chair closest to you (for support) you can do this exercise. you place your heels on the front edge of the chair, and then you place one ankle on the opposite knee (so that your leg is bent and the knee outward). then, in that position, you lift your butt into the air, using the remaining heel on the chair to push up. do 10 for each leg, then stretch and repeat three times, you will DEFINITELY notice it is doing something

A chiropractor fixed mine. Setting down makes it worse, so avoid this. Use a lumbar pad to relieve the pressure on your back. This was about twenty years ago. Still good.

Try attaching industrial bed springs to the under soles of your basketball shoes. Alternatively, you could consume a sack of frog's leg which might help.
