Are you pregnant?
Take a look at our Kneeling chair section. Sitting on a kneeling chair will allow you to drop your knees while sitting down, freeing your bump and increasing blood flow - the Thatsit with Back is our favourite. Alternatively, why not try an office chair with a saddle shape to the seat - the Bodybilt range have a number of chairs with saddle seat designs, allowing the knees to drop quite a bit lower than the hips...
