Sleeping Properly

We now have a new bed. As a consequence my knees are severerly injured. How do you injure your knees in bed? Ah well you see not in bed but walking round the bed. This new bed - light oak, tasteful, comfy - has lower posts than our old bed and they tend to hide furtively under the corners of the duvet. Walking round the bed in the dark - a technique I had mastered and indeed become expert at up until last week - has led to a couple of serious errors of judgement and puncture wounds (sharp stuff this oak) to my lower thighs. Bed itself is very relaxing.
