Last summer I purchased a 4FT Heavy Duty Workbench, followed by the castor wheel kit a few weeks later. It is, without a doubt, the most robust workbench I've ever owned. I use it as both a general purpose table for doing repair on household equipment and as an elevated platform for several pieces of kit when homebrewing; it has routinely taken on over 100kg of weight each day without so much as flinching. I'm convinced it will last me the rest of my life.
Amazing 6ft picnic bench. Arrived in good time, within 3 working days, easy to assemble, looking very pretty in our garden...Really pleased with the order and experience. Highly recommend products from MC timber.
