1. Love the one you are with.  Have you ever looked at the instruction manual to see what all the levers do?  Or have you just plonked yourself down from day one and expected the chair to unconditionally love you and support you.  Well the majority of office chairs can be adjusted to suit you better.  Take a bit of time to look at the instruction booklet and see if adjusting the depth of the seat, moving the backrest or even altering the height of the arms can make you more comfortable during the day
2. Are you just perching on the edge or have you jumped in with both feet?  Quite often people end up perching (i.e. sitting at the front of the chair) rather than using the backrest, because the chair depth is too long.  You can tell if it’s too long, if when you sit with your back against the backrest, the front of the chair digs in behind your knees.  A quick fix to increase the love you feel for your chair, is to add a back support cushion.  A nice thick one will not only give you a bit more lumbar support but shorten the seat a bit for you, so that you can sit back and not feel chopped off at the knees.
3. Like all good things, over time things can go a bit south.  If your chair is no longer in the first bloom of youth, and you’ve found that the years have caused a bit of sagging.  Then like a shot of Botox, a sitting wedge can help to provide a bit of artificial help to increase the padding underneath your derriere (not to mention improve your posture at the same time).
4. Are you a good match?  Is the chair at the right height for you?  When you sit at your desk your arms should bend at your elbows to form a comfortable right angle to the desk.  If you are sitting too low, look at increasing the height of your chair (and if your feet don’t touch the floor use a footrest).  And if you are too tall – it’s not your chair you’ve fallen out of love with it’s your desk (see if you can raise the height of that instead).
5. When was the last time you bought your chair flowers?  Well maybe not flowers, but maybe gave it a good clean.  You have to work at love, and a bit of a dust and a hoover from you can mean that your partnership can last for years.
