More Info:
The GSC beehive spring is made with an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilities. These springs have the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control.

Stands well on high-pile carpet
Color: Beige, Size: 5-panel
Great product! Stands up sturdy on my high-pile carpet. Not too heavy, not too light. It comes pre-assembled in a MASSIVE box, so just be aware. The condition was great, minus one spot that looks like the fabric weave was stained. Not noticeable. Kindof a pain to adjust, but that's not necessarily the fault of the product. Just a finnicky thing to get "just right."

Sturdy, Easy to Use, and Great for Privacy
Color: Black, Size: 88" W, Color: Black, Size: 88" W
This room divider is exactly what I needed! The metal frame feels very sturdy and stable, and the wider bases keep it from tipping over easily. The fabric provides great privacy and blocks light much better than expected. I also love how lightweight and foldable it is, making it easy to move around or store when not in use. Assembly was simple and only took a short time with the included instructions. Overall, it looks great, feels high quality, and works perfectly for creating a private space at home. Highly recommend!

Not bad
Color: Grey, Size: 88" W
Claims to be non see through but you can, easy to assemble but instructions aren't good. Decent money value, quality is okay. Good fit, not very sturdy.

They bend easily and hard to keep up
