Tree Sponge Mushroom Wall Shelf Set – 5-Piece Mushroom Cluster Shelf Design

Tree Sponge Mushroom Wall Shelf Set – 5 mushrooms for a true-to-nature wall arrangement

Turn your wall into a piece of nature: our Tree Sponge Mushroom Wall Shelf Set is a mushroom cluster shelf with 5 mushroom shelves in three sizes (1x L, 1x M, 3x S) that together form a true-to-nature cluster, just the way tree sponge mushrooms really grow on trees.

What makes the Tree Sponge Set special:

• True cluster design: 5 mushrooms in 3 sizes that together form a realistic tree sponge group
• Based on 3D scans of real mushrooms: Every shelf is based on a real tree sponge mushroom from nature
• 5 colors: Blue-Green, Pink-Black, White, Beige, Black
• Arrange it your way: As one connected mushroom shelf cluster or individually in different rooms
• Invisible wall brackets for a true floating effect
• Mounting: Wall-mount hardware included — drywall compatible
• Load: ~2 lbs / 1 kg max per shelf

The cluster idea: Mount the 5 mushrooms close together on the wall, exactly as tree sponge mushrooms grow on trees. The different sizes create lively mushroom cluster wall decor that gets people talking.

Material: Corn-starch-based PLA bioplastic. Hand-crafted in our small Claremont studio in America — every piece is in-house and finished by hand. Made in USA.

Tip: Mount the 5 mushrooms close together as a cluster for the fullest look. The large L mushroom also works on its own as a decorative wall shelf.

Shipping and returns: Made to order in California — ships in ~1-2 weeks, tracked. 60-day returns.

Pairs well on your wall

With the Tree Sponge Set, a whole group already hangs on your wall — now it needs a counterpart. A round-capped mushroom in the same color gives the flat brackets a centerpiece, and a large Gibbosa extends the group downward. That is how a set grows into a wall.

• Amanita – The round cap in L or XL as the centerpiece the five brackets gather around.
• Gibbosa – From the same family of tree mushrooms — in L or XL it carries the group further down.
• Gibbosa Bundle (9-piece) – Nine small polypores in your color turn set and wall into one connected forest.

Every mushroom comes in the same color family as your shelf, so your next one will match the one you already have. We make every shelf to order in our Claremont studio, so your wall can grow at your own pace.

What's in the set
— 5 mushrooms in 3 sizes:

• 3× S: 4.7 × 2 × 2.8 in (12 × 5 × 7 cm) (W × D × H) — The three small mushrooms form the base of the cluster. Perfect for tea lights or small decor objects.
• 1× M: 5.5 × 3.1 × 3.1 in (14 × 8 × 8 cm) (W × D × H) — The middle mushroom as a connecting piece. Ideal for a succulent or a small candle.
• 1× L: 7.9 × 4.3 × 4.7 in (20 × 11 × 12 cm) (W × D × H) — The large main mushroom of the cluster. Has room for a small book, a plant, or several decor pieces.

Total weight & load:

• Size S: about 2.1 oz (60 g) each
• Size M: about 3.9 oz (110 g)
• Size L: about 6.3 oz (180 g) — holds up to ~2 lbs / 1 kg

Tip: In the cluster arrangement, the total area is about 19.7 × 13.8 in (50 × 35 cm) —
an impressive wall picture!

What is your Tree Sponge set made of?

All 5 mushrooms are made from PLA (polylactic acid), a bioplastic made from corn starch.

What makes our process special:

• Each of the 5 mushrooms is made in our small Claremont studio in America — no overseas mass production, just real handwork. Made in USA.
• After printing, every piece is sanded by hand and checked for quality. Small differences in the surface are intentional — they come from finishing by hand
• PLA is sturdy and durable — your shelves hold small books, plants, and decor with ease
• Easy care: just wipe with a damp cloth. No special cleaners needed

Note: PLA is splash-resistant but not suitable for wet areas (showers) or outdoor use. Don't put it in the dishwasher or clean it with hot water, because PLA can soften at temperatures above 140 °F (60 °C).

What you'll get:

• 3× Tree Sponge Wall Shelf size S in your chosen color
• 1× Tree Sponge Wall Shelf size M in your chosen color
• 1× Tree Sponge Wall Shelf size L in your chosen color
• 5× floating wall brackets (invisible behind the shelves)
• 7× screws + 7× wall anchors
• 1× illustrated mounting instructions with cluster arrangement suggestions

Mounting — it's that easy:

Here's how:

1. Lay the 5 mushrooms out on the floor to find the arrangement you want
2. Mark the positions on the wall — the brackets serve as templates
3. Drill two holes per mushroom and insert the anchors
4. Screw on the invisible brackets
5. Slide the Tree Sponge mushrooms onto the brackets — done!

Time needed: about 10–15 minutes for all 5 mushrooms.

Important: Please screw down all five mushrooms. Adhesive pads and mounting glue can't carry the load of a filled shelf — screws and wall anchors are included.

Pro tip: Arrange the mushrooms close together — with the largest mushroom (L) on top and the small ones (S) around it. That creates the signature tree sponge look, as if the mushrooms were growing naturally on your wall!

What is the shelf made of? Is PLA sturdy enough?

Absolutely! All 5 mushrooms in your Tree Sponge set are made from PLA (polylactic acid), a corn-starch bioplastic that's surprisingly sturdy. Each shelf holds up to ~2 lbs / 1 kg. Contrary to what you might think, PLA is very stable and durable. Your Tree Sponge set will stay with you for years. The only limitation: PLA isn't suitable for wet areas or outdoor use and shouldn't come into contact with water above 140 °F (60 °C).

Which color works best with my decor?

It depends on your style — and with the Tree Sponge set, color looks especially striking as a group thanks to the 5 different shapes:

• Black — the all-rounder. Goes with industrial, modern, and Scandinavian. The different mushroom shapes look especially sculptural as a dark cluster.
• White — subtle and elegant. Perfect for bright, minimalist rooms. The cluster comes alive through subtle shadows.
• Beige — warm and natural. Ideal for boho, Japandi, or earthy color schemes. Closest to the real mushroom color!
• Pink-Black — the eye-catcher! A statement set for bold interiors or as an eye-catcher in the kids' room.
• Blue-Green — fresh and striking. Great in a kids' room, home office, or as a contrast in bright rooms.

Tip: Beige or Black are our recommendations for the most natural
tree sponge look!

Does the wall shelf set make a good gift?

And what a gift! The Tree Sponge set is one of the most popular gifts at Roomberry — for birthdays, housewarmings, Christmas, or just as a surprise. Why? Because it's original, hand-crafted in America, and something the recipient almost certainly doesn't have yet. 5 mushrooms that together form a work of art — who else has that? We ship in neutral, high-quality packaging — perfect for passing along as a gift.

How should I arrange the 5 mushrooms?

That's the beauty of the set: it's completely up to you! Our favorite: all 5 mushrooms close together as a cluster — with the largest mushroom (L) on top or in the middle and the smaller ones around it. That creates the natural tree sponge look. But you can also hang them spread out, in a row, or even split them across different rooms. You'll find several arrangement suggestions in the mounting instructions. And best of all: you can rehang them anytime and try a new arrangement!

How long does shipping take, and can I return it?

Made to order in California — ships in ~1-2 weeks, tracked. Because every shelf is made to order, we need a few days to produce and quality-check all 5 mushrooms. In exchange, your set is made fresh just for you. Shipping is calculated at checkout. And if you don't love it after all: you have 60 days to fall in love — otherwise just send your order back to us.
