Working from the sofa without your back paying for it
Nicola Tik
Sometimes the sofa is just where the day happens. The laptop comes out, an hour turns into three, and by the afternoon your lower back is letting you know about it. Here is the reassuring bit: your back does not really mind sitting. What it minds is the shape a soft, low sofa quietly folds you into, and that part is easy to work with.
A sofa is built for relaxing, not for working, so the seat is deep and soft and there is nothing firm behind your lower back at the right height. Sink into it and your pelvis rolls backwards, which flattens the gentle inward curve your lower back likes to keep. Studies that measured the pressure inside the discs of the lower back found that a slouched, unsupported position tends to load them more than a well-supported one. In other words, it is the slump, not the sitting, that your back feels.
The quickest win is to build the support the sofa is missing. You could try tucking a firm cushion or a rolled towel into the small of your back, then sitting right into the corner of the sofa so the armrest and the back both help hold you. If your feet dangle, resting them on a footstool or a stack of books lets your legs share the load rather than your lower back taking it all.
A laptop flat on your lap drags your head and chest down towards it, and the whole of your back rounds to follow. Propping the laptop up on a cushion or a box, so the screen is closer to eye height, lets you sit taller with far less effort. If you can pair it with a separate keyboard, even a cheap one, your back and neck will notice the difference over a long day.
No setup, however good, is meant to be held for hours on end. Your back is happiest when it gets to change position often, so the sofa becomes far kinder if you get up now and then to move, stretch or simply stand for a call.
