Why Designers Choose the Seeley Cube

The Seeley Cube is the foundational choice for anyone who appreciates clean, minimalist geometry. If you have ever seen a standard plastic planter warp or fade after a single season, you will appreciate the industrial-grade difference here. It is designed to be a permanent, design-forward extension of your architecture.

In professional settings, these are most often used to create a "ceremony of arrival" at entryways or arranged in a rhythmic series to create a "living wall." Because the lines are so crisp and the matte finish so refined, the Seeley Cube defines space—like an open-plan office or a sprawling patio—without adding visual clutter. It anchors the environment, allowing your greenery to take center stage.

The Science: Why Steel-Reinforcement Matters for Large Planters

Most large planters suffer from "bellying"—a phenomenon where the sides bulge outward once filled with heavy, wet soil. This ruins the architectural silhouette. To prevent this, NMN Designs integrates internal steel reinforcement into our 20", 24", and 30" models.

This engineering ensures that even when housing a heavy, mature tree, the walls remain perfectly plumb and vertical. Combined with our commercial-grade fiberglass, you get a vessel that handles extreme thermal expansion (from scorching summers to sub-zero winters) without the cracking or brittleness found in standard resin or plastic pots.


Engineered for Performance: Indoor and Outdoor Versatility

The Seeley Cube transitions effortlessly between environments. For interior use in a foyer or gallery, keep the rubber plugs inserted for a watertight seal. For outdoor installations on a deck or patio, simply remove the plugs to ensure vital drainage and oxygen for the root zone.

Recommended Tree and Plant Pairings by Size:

  • 14" Cube (Medium): Ideal for architectural foliage and "tree-like" indoor plants. Best for Snake Plant, ZZ Plants, or a Spider Plant. Perfect for office corners or flanking a residential console table. Outdoor - Ornametal Grasses, Small Plants.

  • 20" / 24" Cube (Large and Extra Large): The perfect size for entryway ceremony and ornamental trees. Ideas include Evergreens and Boxwood Topiaries, Ornamental Grasses, Olive Trees, or Fiddle Leaf Figs. For a vertical architectural look, Sky Pencil Hollies are excellent.

  • 30" Cube (XXL -Extra-Large): Designed for specimen trees and high-impact privacy. This volume is required for larger trees such as Japanese Maples, Dwarf Citrus (Lemon/Lime), or Serviceberry. To create a privacy screen, plant a series of Emerald Green Arborvitae or Tall Ornamental Grasses.


Pro-Tips for the Best Results

  • High-Wind Stability: For exposed roof decks or coastal balconies, add 3 inches of heavy gravel at the base before adding soil. This lowers the center of gravity, ensuring your privacy screen stays upright during heavy gusts.

  • Thermal Protection: While the fiberglass is frost-proof, using an insulated liner inside the planter in extreme northern climates can help protect the root balls of perennial trees, ensuring they return season after season.

    Great WFH screen for video calls
    Color: Black, Size: 22"- 4 Panel
    I share a workspace with my hubs since we both work from home. I have the attention span of a 🐿️ and need this so I can focus on my work and not get distracted by him, since he is very amusing to watch. This screen is very lightweight and the panels can move and create a little cubicle around your workspace. I personally loved cubicles & despise open space seating, even at home. The ADHDer in my loves being able to block things away from my field of vision. These panels also hide any mess behind you, especially if you forget to blur the background on Teams or Zoom calls or if you don’t have the option to change your backgrounds. This was fairly easy to put together and very easy to move and adjust. The screen is a much better option than a sheet as I’ve seen others use on calls.🤦🏻‍♀️😂 I’m not sure how it will stand up around rambunctious pets or kids, but fairly certain it takes quite a push to knock it over. We have four cats & I’m pretty sure someone would try to climb this, which is why they’re not allowed in our workspace.

    Difficult to assemble, but a good basic divider
    Color: Beige, Size: 22"- 4 Panel
    I bought this to use as a background for when I have video calls. I wish I'd ordered the 6- or even 8-panel to block a little more, but that's my own error. It still covers a good portion of the room, so I'll make do, or maybe buy another at a later date to expand it. It looks ok, if a little plain. The fabric panels have creases in them from being folded and will need to be steamed or ironed out for a nicer look. It would be easy to make your own panels as well, if you're so inclined. The construction is decent. The frame is lightweight and if you don't angle the base supports the right way it may tip over if you extend it too far. The fabric panels aren't the highest quality, but are sturdy enough. They seem like they would handle being thrown in the wash well. The only issue I have with it is that it was so difficult to put together. The push latches that connect the poles don't push it well and hurt my hands. The fabric panels are sized to be extremely taut, which makes it very difficult to get them on the bars without forcing the bar to bend slightly. Overall, this is a good divider if you're looking for something simple and functional without being too worried about aesthetic. It's also a good, inexpensive base if you want to make your own custom panels.

    Great Room divider
    Color: Beige, Size: 34"- 3 Panel
    Works well in separating my kids play area from my computer/office room. Easy to put together, height is perfect somewhat sturdy, looks great, light weight, not good if you are using it as a door, but if it is to stay in place than it is stable enough.

    Exactly what I needed
    Color: Black, Size: 34"- 3 Panel, Color: Black, Size: 34"- 3 Panel
    It was easy to put together even without a power drill. Completely opaque. Only a very small slit between poles. I plan to add black electrical tape, but that's because I don't want nosies peeking through to see my screen. The height is beautiful. I was afraid it wouldn't be as tall as I needed. But it is perfect. I share a small office with a good buddy of mine. People passing by our door is distracting and invites them to speak to me. I needed something that would stop the former and prevent the latter, especially when I'm deep in concentration mode. The two panels are enough to block outsiders and the third panel I will employ when I can't even be disturbed by my officemate. It's the fastest and easiest signal not to disrupt me at all. 10/10

    Packaging contents
    Color: Grey, Size: 34"- 3 Panel
    Item is as described however this one appeared to be open and some parts possibly used. Example pole packaging mislabeled one had the letter K as a part there is no letter K item in the instructions. Another pole part had a taped on letter A which is completely different from the others thus indicating that it was opened or substituted. Finally after the partition was completely put together one of the bottom screw connection anchors came out making the partition unable to stand. I'm going to have to rig something up in order to get the anchor connected to the bottom panel. In closure the partion could be very acceptable and do the job if it was new and parts labeled correctly. I have pictures of all parts and packaging errors. Would buy again if new. I'm going to pursue some kind of compensation.
