Materials

Every material has a reason.

Sisal, beech wood, and wool felt – consciously chosen, designed for longevity.

Sisal

Sisal embodies resilience. Derived from the leaves of the agave – long-lasting, robust, naturally coarse. Exactly what cats need. Exactly what outlasts furniture.

100% natural material

Beechwood

Beech stands for durability. Solid wood substructure, multiplex platforms – stable, low-maintenance, timeless. From sustainable forestry in Europe.

Solid & Plywood

Wool felt

Wool felt offers softness. Made from pure new wool, breathable and temperature-regulating. Certified according to OEKO-TEX® Standard 100.

Frequently Asked Questions

Everything you want to know.

Model & Dimensions

Which model suits me — H1, H2, H3, or H4?

H1 · The Sanctuary

120 cm · 1 platform

Entry into the system. Compact, expandable, for every room.

H2 · The Companion

170 cm · 2 platforms

Two levels. Fits into any apartment with a standard ceiling.

H3 · The Explorer Bestseller

220 cm · 3 platforms

Three levels for active climbers. In Germany, any space taller than 230 cm is considered living space - so the H3 fits everywhere.

H4 · The Visionary

270 cm · 4 platforms

Statement piece. For rooms 270 cm and taller — and cats who claim every inch.

→ Not sure? Measure the ceiling height, then decide.

What are the dimensions of the H-Tree and how much space do I need?

The H-Tree uses height, not floor space. The footprint is deliberately narrow – it requires significantly less space than its appearance suggests.

Model	Height	Width	Depth
H1 · The Sanctuary	120 cm	75 cm	32 cm
H2 · The Companion	170 cm	75 cm	41 cm
H3 · The Explorer	220 cm	75 cm	50 cm
H4 · The Visionary	270 cm	75 cm	59 cm

No blind spots underneath. The H-Tree has no base plate — the floor underneath remains completely clear. Books, a plant, a basket — the space is yours. And anyone who's ever tried to vacuum under a classic cat tree knows: this is different.

Assembly & Stability

Is the H-tree stable? Do I have to mount it to the wall?

30 kg per platform

2 Screw on top

The H-Tree is inherently stable—like a ladder. To secure it against tipping, it is fastened to the wall at the top with two screws.

The screws have no load-bearing function — the construction itself bears the weight. They exclusively secure against tipping. The keyhole system is invisible from the front and can be removed without tools.

Regarding load capacity: Each platform holds 30 kg. We have even stood on it ourselves – the H-Tree didn't complain.

I am a tenant. Can I install the H-Tree without drilling?

Yes — with the optional Window Mounting Kit (sold separately).

The kit completely replaces the two upper wall screws. Instead of attaching to the wall, the H-Tree attaches to the window — via two 75 mm industrial suction cups directly on the glass. Transparent, residue-free, no drilling.

Each suction cup has a pull-off force of 14 kg — 28 kg combined, significantly more than the weight of any H-Tree configuration.

Additional benefit: The cat gets the best position in the room — height, natural light, unobstructed view outside.

Manufacturer's specifications. The kit is sold separately.

Which plugs and screws do I need for my wall?

For wall mounting, a drill is necessary. Mounting hardware for standard walls is included. The H-Tree is fastened to the wall with two screws at the top.

Solid wall / Concrete

Use the standard wall plugs supplied.

Plasterboard

Cavity anchors necessary - separately from the hardware store, not in the standard set.

Bricks

Standard anchors, possibly slightly longer depending on the plaster layer.

Can the H-Tree hold multiple cats?

66.14 lbs per platform

The H-Tree can hold more cats than it has room for.

That's not a marketing statement — that's physics and beechwood.

Material & Sustainability

What materials is the H-Tree made of?

Supporting structure

Solid beech wood – visible, tactile, authentic.

Platforms

Plywood — stable, uniform, durable.

Sisal

Natural fiber for the scratching elements. Replaceable when worn out — the product remains, only the sisal is renewed.

Wool felt

Natural comfort layer. Regulates temperature — warm in winter, cooler in summer. No synthetic fibers.

No MDF No synthetic carpet No plastic

How long does the sisal last? Can I replace parts?

Yes — replacement is part of the concept.

When the sisal is worn out, you only replace the scratching element — not the entire H-Tree. Each module is individually replaceable. Spare parts are available directly at htreestudio.com.

How long does the sisal last? That depends heavily on the cat — on how often they scratch, their technique, and which elements they prefer.

What we can say: when it's time, you'll know — and the rest of the H-Tree will continue to function flawlessly.

Why does the H-Tree cost more than other cat trees?

Because he's not a scratching post.

Supporting structure

Solid beech wood – visible, tactile, authentic.

Sisal

Natural fiber for the scratching elements. Replaceable when worn out — the product remains, only the sisal is renewed.

Wool felt

Natural comfort layer. Regulates temperature — warm in winter, cooler in summer. No synthetic fibers.

The cheap scratching post will be replaced in two years. The H-Tree won't.
