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.

    Full of beauty!
    Size: 2' x 6' (Sheepskin shape), Color: Creamy White
    This company takes pride in their work. The sheep skin covering is beyond what anyone could imagine. I purchased this for medicinal purposes. I found out I have SI joint dysfunction. And this sheepskin helps to relieve pressure points so I am using this as a chair covering for when I sit. The product came in a big box and then a plastic bag and then a third, well covered, plastic bag to protect the sheepskin. You will not be disappointed if you purchase this covering. The price was excellent. It will take your breath away. Very happy with my purchase. There was no odor when I opened the package. Many thanks for an excellent product and helping me to be more comfortable when I sit for short periods of time. :)

    Nice, but almost feels faux to me
    Size: 2' x 6' (Sheepskin shape), Color: Pink, Size: 2' x 6' (Sheepskin shape), Color: Pink
    I like it, but it says it’s real, and I believe them, but it feels like it is faux. I’ve owned a fake one before and it feels similar. Please know I am not saying it is not real. I guess the fake was well done! It’s super long and I am still on the fence if I want it this long. I’ve taken a pic here, but right now it is wrapped in the package in case I need to return. It is soft and pretty, but I’m not sure that Barbie pink is my best choice lol. Usually I would pair it with a mid century modern bedspread that is chenille, with a little pink so it works well but not too matchy matchy. I wish I had taken a pic with that bedspread because the bit of pink on the bedspread looks very nice against the rug. So let me apologize for having it with an ugly bedspread.

    Exceeded expectations in every way.
    Size: 2' x 3' (Sheepskin shape), Color: Gray Tip, Size: 2' x 3' (Sheepskin shape), Color: Gray Tip
    I purchased a pair of these a week apart, because the price seemed too good to be true. Instead, they have exceeded my expectations. I own a Buick with leather seats that look incredible, but are not comfortable on long trips, and my wife and I were preparing to leave on a 2200 mile round trip vacation. On the first day, we drove 700 miles, much of it through desert. We were tired when we reached our destination, but comfortable and cool for every mile of it. The sheepskins have made such a difference, that I have never removed them from the car. It is now July, with triple digit temperatures every day, surrounded by desert. The sheepskin keep us cool on every drive. I could have purchased sheepskin seat covers, but these provide the same comfort for a fraction of the cost. Yes, it takes a small amount of effort to adjust them when you first get into the car, but I don't even think about it any more. As far as the quality, there is no shedding, no smell, and no discoloration. We have put over 4,000 miles on the car since I put these in, and I have no complaints to register.

    Great product: thick and cozy
    Size: Single Pelt/2 ft x 3 ft, Color: Natural (Ivory Whiite)
    This is a lovely, thick sheepskin. I’m using it to drape over a chair. It’s very soft. The color is a natural white. Arrived quickly. The price was great for such a wonderful sheepskin.
