Worth ordering the samples first
Ordered the sample box first — that already felt like a Lignahauss thing. When the full order arrived it was wrapped in kraft paper with a handwritten card. The wood looks better in person than online.

Sceptic converted
I rarely buy wood online. This was the exception. Installation took forty minutes, the brass fixings feel solid, and the finish doesn't look like a panel — it looks like furniture mounted on the wall.

Quiet luxury, delivered
I specified Lignahauss for a client's reading room and got pushback on the budget — until the install went up. The room reads warmer, the acoustics are honest, and the client called the next day to extend the order.

Acoustic difference is real
Bought the Smoked Walnut for a small recording booth at home. The reverberation drop is measurable — I checked with my DAW before and after. No marketing, just numbers.

Customer service that stays
Damaged one panel during a clumsy lift. Emailed support expecting a fight — got a replacement in five days, no charge. The slat sits flush, the felt backing is generous, and I'd order again without hesitation.
