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.

    Comfortable fit for arthritis hands and on the fly functions.
    Color: Grey
    I bought my wife this mouse in 2022 and she has had no issues with it. I had a different wireless mouse that I used that started causing issues in my everyday working and the speed and clicks of the mouse were causing issues. I decided to steal her mouse for a while and found, wow, this is great. I bought myself on and totally love the response I get. The DPI change on the fly is the game changer for me. You can instantly click to change the speed of the curser and make your clicks more accurate. This will be my mouse for choice. I have arthritis in my knuckles but, this mouse does not bother my hand at all. totally comfortable for a 12 hour workday.

    A Truly Ergonomic Mouse
    Number of Items: 1
    Other not completely flat mice claim to be "ergonomic", but the only way to completely remove stress from your forearm when using a mouse is with a "vertical" mouse. My 2020 K75575WW Kensington ergonomic vertical mouse developed a problem with the left button "stuttering" so that it sent multiple button clicks when pressed just once. I liked the Kensington quite a bit. But it always just a little bit on the "not quite as solid as I would like" side, and failing after just 2.5 years confirmed this. So I wanted a more solidly build mouse. A search for "ergonomic mouse review" showed that the Logitech MX Master 3S was clearly the best ergonomic mouse available. At $100 it was several times more expensive as others including the latest Kensington vertical mouse. But sometimes furgal doesn't mean the least expensive. Sometimes it can mean the most expensive if that comes with better performance, features and lifespan. So I ordered it. And while it is indeed an incredible mouse, the angle is only about 20 degrees. The result is that while there is some reduction in forearm stress compared to a flat mouse, it wasn't enough for me. By the end of my very long days driving my mouse almost as much as I drive my keyboard, I could feel the tension building up in my forearm. So after a week I returned it and bought this Logitech MX Vertical. It is slightly less expensive than the MX Master 3S, but still much more expensive relative to other options. And while it is lighter and a little less substantial feeling in my hand than the MX Master 3S, it still feels very firm and solid. Most importantly keeps my hand in the neutral position with my fingers at about 70 degrees. A great feature of the MX Vertical shares with the MX Master 3S is the thumb rest. The Kensington didn't have this and so my thumb rested on the desktop. If it was a bit warm and my hands would sweat my thumb wouldn't slide smoothly and I would have to lift my thumb off the desk when I went to move the mouse. Not a horrible thing, but if you spend 8+ hours mousing around it gets tiresome. The button clicks are crisp. Best of all when the button bottoms out it feels like it is pressing against the case. It doesn't feel like travel is being limited by the switch itself bottoming out like the Kensington felt like it did. My hope is that this will keep the switch from wearing out so fast as happened with the Kensington. One slight negative of the MX Vertical is that I don't feel like I am quite as accurate in being able to move the cursor to a specific spot on the screen without some amount of conscious effort. Instead it doesn't go exactly in the direction I intended and overshoots where wanted it to stop. As such it might not make the best mouse for video games. [UPDATE: There is a bit of a learning curve in moving the mouse accurately. In the last couple weeks my need to make a more conscious effort to move the mouse to a specific spot on the screen is going down. Still think it is likely to not be as accurate as a flater mouse]
