Question: Can you add wheels to this unit to make it mobile?
Document: This unit took minutes for my college student daughter to assemble. In fact, she assembled two of them. This unit offers good protection with a complete zippered cover. Once you have hanging clothes in it, it will not be too easy to move. If it had wheels on the bottom it would not be as sturdy. These were a good value.
Again, since I had already assembled the cheaper brand, I figured it out fairly easily. However, the other brand has identification on every piece. This one did not come with any crossbars for the upper rods; the other model has three. This one has no additional support in the center of the vertical posts; the other does. This one did not include anything for the bottom of the unit. The other model does, although it is only a nice piece of cardboard to add some rigidity.
***To solve the bent bar/broken frame problem I bought an *additional* adjustable HEAVY DUTY (read: strong metal bars- like those found in a normal closet) closet on wheels WITHOUT without the cover and installed it INSIDE this covered contraption. I did use the wheels on the new non covered closet to go over the existing frame of the old closet and to make level. Now, I have the best  of both worlds. A heavy duty professional closet bar/ stand inside a covered closet.
We don't have a closet so don't know how all winter clothes are going to fit in it. Don't have dresser either. Using sterlite storage on wheels.
Built with not that strong material but I did put a lot of clothes in it and 2 weeks now but still holding strong. The size is good and closet cover is of breathable material which is nice! Wish closet stood on wheels so I can roll it around.
Fast delivery. Product is as described and the rewiew stating to assemble in the cover was great. My husband had no trouble putting it together. The only issue I see is with my putting too many clothes in it. I tend to over "load". We are discussing ways to add extra support.
lots bigger than i imagined, not hard to put together. i did it myself after reading some posts detailing how. just great fabric. my husband's clothes are very heavy at 3xl and this works even when full. i have tried to sway it slightly and it seems to be sturdy. great price. odd description on amazon, i called company and they will look into it. thought it had wheels but they say none of there larger closets do
Product is sturdy.Holds quite a bit of hanging clothes & the bottom can be used for shoe boxes or whatever.Our 5 & 6 month old kittens love going in & out,playing & always sleeping in it.Hemmy loves to climb up to top but it already has pull marks on it from his claws. Have to trim them I guess. You can put light weight things on top. It's a good thing it doesn't have wheels or wouldn't be as sturdy.
This product seemed perfect for my evening gowns and off season hanging clothes. Unfortunately, it's cheaply and poorly constructed.I'm an engineer, so putting it together wasn't too painful...except that the cloth part of the closet really is just too tight a fit over the skeleton to get on without tearing a seam or two. Would it really have been that difficult to add another 1/8 of an inch of fabric??
I was able to put this together without help in less than 20 minutes, and I am female, and 62 years old. I have had to add my elderly Mom to our household, and there was just no room for winter and summer clothes in the same closets. WaLa! This portable closet fit easily in a rented storage compartment, and I was able to hang 40 outfits of winter clothes, zip up the cover, and now I have room for Mom's clothes.
