Dearwall - Main unit

Dearwall is an item that can be used to create pillars indoors. Just cut wood and place it on a pad and use the spring to tension it up and down.
 No tools or ladders are required, so anyone can easily install it.
Since you don't need to drill holes in the walls or ceiling, it's safe even for rented properties. Dearwall is made by construction material professionals, so you can enjoy full-scale DIY.
