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.

    Short sleeve button down shirt
    Size: XX-Large, Color: Navy Blue
    These might run a size smaller. It still fit me but it is closer to XL than XXL in my case. It is great and comfortable as a casual shirt to wear out. It is easy to wash and dry, it did not shrink with cold water and just a tumble dry.

    Comfortable, roomy fit and quality fabric
    Size: Medium, Color: Flamingo, Size: Medium, Color: Flamingo
    This is a comfortable, well-made guayabera (Cuban wedding-style shirt) available in a range of colors. It fits true to size on me, offering a little extra room to help you contend with the summer heat. The color and size hold up well in the wash; I've worn this shirt several times and it still looks great and hasn't suffered from any kind of shrinkage at all. I particularly like the linen blended with cotton here; linen is nice and light but can be too light sometimes and it wrinkles when you look at it, but the cotton balances it out nicely. The current discounted price of $20 a pop here is an absolute steal as well; I'm tempted to get another couple just to have some more options in my closet. Overall, I'm happy with this product.

    Excellent dress shirt for the summertime!
    Size: X-Large, Color: Navy Blue, Size: X-Large, Color: Navy Blue
    This has rapidly become one of my top shirts to wear during the summertime, and it isn’t even summertime yet! Got this shirt in the other day and this shirt just checks all the boxes for me. It is comfortable in fact that it’s very comfortable. The material is not dry fit but it is not a material that will make you sweat the way cotton would make you sweat.. the fit is spot on, and it just happens to be one of those shirts (we all have shirts like this) where it is one of the go two shirts that you grab when you wanna look nice, yet you wanna be comfortable. Another thing I like about this shirt is the collar it doesn’t stick out too far and it just seems to fit in place the right way. Some collar on some shirts rest too far outside of your neck and some hug along your neck line, this shirt does neither of the two, it just fits perfectly. The material is very breathable allowing this shirt to be worn in any nice weather climate whether that is warm, hot, or that very sticky humid hot.. Another great thing to point out is I have washed it twice already and it keeps its nice clean look to it and I have not really had to go crazy with the ironing. For the price I think it is aAnother great thing to point out is I have washed it twice already and it keeps it’s nice clean look to it and I have not really had to go crazy with the ironing. For the price I think it is a steal of a deal, yeah I wish I had a closet full of these shirts with other colors.

    Great watch
    Color: Green
    This watch is two times the price of the he casino watch but it is so much better. The indigo dial lights up completely from all angles. It is easy to read even in 0 light. Much more durable and runs on 1 battery instead of 2 batteries in the Casio. Can’t go wrong with this watch!!!
