I always read reviews before purchasing- so I understood this was going to be a small, light weight tri-fold. It is not meant to be extremely durable- so it wouldn't be great to have around children or animals - but is functional for certain situations. I use this as a divider between my work from home desk and my bed during the day and it is the perfect tool to keep my brain in "work mode", and not sleep mode.

Love them! Well made!

Color: Dark Mocha, Size: 3 Panel

Very nice product, nice color. Just too short. Will be sending back for a taller one to match other 2 I ordered! Great customer service!

Looks good and is stable

Color: Dark Mocha, Size: 3 Panel

This is perfect for my needs. I have a large bathroom window that anyone can see the toilet when the window is open. The weather is so beautiful here for many months and I hated keeping that window closed. This screen is perfect. It covers the open part of the window so no one can see in but the air flows freely (the glass is frosted so it is not a problem when closed). The screen is very lightweight and came fully assembled (which is amazing anymore). It feels stable and I think it is a good value for the money.
