SureLegs - Table Risers are an innovative way to make "H" and "Wishbone" Leg tables the perfect height. Buy THIS product and SAVE YOUR BACK! Our quality SureLegs come in sets of 4 and are made of Heavy Gauge Steel to last. We finish the SureLegs off with a high-quality rubber non-skid tip to provide extra stability. Note: Table heights may vary slightly due to the contour of your tables' legs. 3 Steps To Find The Right SureLegs - Table Risers: Step 1: Measure your table leg from the floor to the first bend. Step 2: Subtract that number from 29 (which is the height of your table). Step 3: Decide how high you want your table and order the appropriate SureLegs - Table Risers. Example: A 29" table with a 4" (table leg bend) will rise to 41" with our standard 16" SureLegs - Table Risers We make other sizes to fit your needs. If you have any trouble finding the perfect height, please do not hesitate to contact Sheila Rae, Customer Service - 517.610.1467 Note: Watch our demonstration video to see an example of "H" or "Wishbone" Leg tables, because they do NOT work on straight or Square Legged tables.
