They say when you purchase an item for comfort, that you shouldn't sacrifice quality for cost.  I realized that this was never more true than when purchasing a new bed.  I must have tried every bed in multiple stores before finding the perfect mattress. There is nothing that can replace the maximum support and comfort while you are sleeping.  

This might be good advice when you are laying down, but what about when you are on your feet?  Even with a comfortable pair of shoes, standing hours on end can be rough on your feet and back.  When working at your cleaning station, you may want to consider using an anti-fatigue mat to help relieve stress on your body.  If you are working in a sterile processing environment, you will want to be sure that the mat can be cleaned in an automated washer and even steam sterilized, if necessary.  This will provide maximum body support on an optimally decontaminated surface.
