What to do if the beech top has war

What to do if the beech top has warped?1.First check whether the room climate (moisture/temperature) fits.2.If you could state that the room is too damp or too dry, make sure that you have a suitable climatic balance, or choose a different location that better meets climatic requirements. In most cases the beech top returns to its normal state. 3.Is the ambient climate appropriate, please refer to the retailer where you purchased the workbench. Your retailer will initiate a complaint procedure (only in case of newly acquired products). In case of workbenches which have been delivered for some time, we must assume that the defect is not caused by our fault (incorrect handling/set up e.g.).4.In case of exceeded tolerances in relation of newly acquired ANKE products with solid beech top, after examination of the wood balance moisture through our site, we are then unfortunately forced to charge the costs for examination, eventual pick-up and new delivery, as well as revision measures agreed with the customer.
