The Original Mattress Factory follows these steps when upholstering a box spring in one of our factories.

A box spring with an Amish built wood-frame is selected based on the model to be upholstered. Box springs vary based on the amount of wood and wire used. The box spring unit is placed on the pre- upholstery table and corner straps are attached.
An insulator pad is then placed on top of the unit and wrapped on all four sides. Next, the cover is fitted over the whole unit.
The boxspring is then flipped over onto the box spring upholstery table and compressed about 1 inch. The cover is then attached to the frame using a pneumatic stapler.
A layer of non-woven material is then stretched across the box spring and secured to produce a dust barrier. The box spring upholstery is then complete.
