Here at Versare we build our room dividing units with safety, strength, and portability in mind. We use an aluminum frame that is super strong and durable, but lightweight at the same time. Other brands use a heavy steel frame, which makes moving rom dividers difficult and dangerous. We at Versare make it very, very easy for all of our customers to move their partitions when necessary without requiring heavy lifting, manpower, and putting their safety at risk. One of our customers recently put it wonderfully: “Thank you again. Also, the partitions are fantastic. I've dealt with those heavier ones before, and they seem like old relics compared to your product.” -Ryan Ryals Heres a pic of an "old relic"....ouch!
