The Garden Mart is designed to be a modular, low-cost and movable sales building for added spring plants sales. Strong, simple, and efficient, it provides protection for your plants and a comfortable shopping space for your customers. This retail greenhouse is built for easy setup, future expansion, and long-lasting use, making it a smart investment for any garden center or nursery.

The sturdy 2" O.D. 14-gauge galvanized steel frame supports a clear or white 6 mil poly covering on the roof and endwalls, with roll-up poly sidewalls for adjustable ventilation. Slide-side ventilation is also available upon request. Inside, an integrated display bench system and four runs of hanging basket purlins—two over the center benches and two over the outer benches—offer plenty of merchandising options for plants and hanging displays.

A wide six-foot opening, covered in durable twin-wall polycarbonate, provides easy access for customers and carts. The Garden Mart can be secured with water tubes, ground stakes, or leg stands to stay protected from high winds. All components are designed for quick, snap-together assembly, and detailed installation instructions are included for fast, hassle-free setup.

Fantastic
Color: Beige, Size: A-132''W-6 Panel
I am perennially in the process of rearranging, reorganizing, getting ready for yard sales, changing the functions of various rooms, moving everything out of a room to do a deep clean, etc, which means that there is always SOME part of my house, if not the entire thing, that is a disaster zone. Having someone knock on my door triggers a "duck and cover" reflex because it's so embarrassing for anyone to see that I live like this. (I *feel* like I don't, really, because I know that all the various stages are all temporary, but when there's always something temporary going on, it might as well be permanent, you know?) So THANK HEAVENS for a room divider that is not only large enough to divide my uncomfortably long den in half the long way so I can shove all the messy parts up against the back wall -- that is not only simple and attractive and neutral and (this is important) NOT BLACK because I have multiple pets and anything black in this house will be pet-hair-colored within 20 seconds -- that not only has **SIX** panels for lots of options of how I want to divide the space/s -- but is also on WHEELS. Someone out there really does love me, it's true! The panels are stable *enough* - I'm not going to lie and say that nothing is going to knock them over, because I have some balance issues, and I also have cats, and both of those circumstances has resulted in a mess on at least one occasion. But in the cats' defense, they've never dealt with a room partition that didn't hang from the ceiling before; and in my defense, I just grabbed the first thing I could reach on the way down. Not the product's fault in either case. Assembly was a little dicey as I am currently in **bilateral** (oh yes, that's fun) wrist braces, so I had to give up until I had help. But I think if you're able-bodied, you shouldn't have any difficulty. The only down side is, now that I've hidden away all the mess so I can break out the holiday decorations, you know what happens next, right?? That's right... the PERMA-MESS ZONE. Oh no. Oh well.

Difficult assembly, doesn’t fold well, looks good fully open
Color: Grey, Size: B-88''W-4 Panel
The instructions for this divider are very inadequate. After having to redo parts of the assembly, I have finally assembled it. The divider itself seems very nice when it is fully open, however it is not possible to fold it well as all the bars with the wheels go in various directions making it impossible to fold it neatly. And it has a large footprint. It is possible that I did not assemble it fully well because of the lack of adequate instructions. I am not even sure if I will keep it because I need to fold out of the way when nothing in use.

Slightly challenging build
Color: Beige, Size: A-88''W-4 Panel
This was my second screen set I've purchased, first of this style. Not the easiest to assemble. Lots of pulling and tugging; not a highlight in my day.

Commercial grade divider suitable for many needs
Color: Beige, Size: A-132''W-6 Panel
This item will be used at a future event where we need to separate a single locker room into two large areas, without any construction. This divider is perfect for the job because the partitions can be 1 to 6 panels and it will roll into place. When the event is over, the divider will fold/roll away and the locker room will return to its original design. The unit is very heavy, which will ensure that it is sturdy and stable. All the components arrived, wrapped in plastic to prevent damage. The screen material is a woven polyester in a cream color that will occlude any visibility but it may be possible to see shadows on the opposite side. The height is about 6ft, which would require a very tall person to "peep over" the divider. I needed a quality unit for this project and the frame, screens, and mobility will meet the needs. The divider is not the same as the small decorative dividers -- it is more of a commercial grade product, yet tasteful. If you want/need a small divider as an accent piece, this is not the best choice. This item could be used in a medical office, treatment/massage room, to divide an office room into two, or block a hallway in a building.
