Second day back at work yesterday and the seat support thingee I bought didn't help me make it to the end of the shift as well as it seemed to Monday. Paid vacation for a day or two until I can put together a more effective lower spine support for use on a forklift truck. Already sent the money to Amazon after I got home from work for attempt No. 2. A couple different designs of L-spine/abs braces and a small seat pad to alter the angle I sit on the seat. If this doesn't work I spend the hundred bucks for the pro-model seat back cushion, I guess.
There certainly seems to be real science behind all of this technology design, but I'm not doing any of it. Vitamin I stacked with codeine will get you through the night though.
