Turn a blank wall into art that calms the room
A bare wall doesn't just look unfinished — it bounces sound straight back at you: harsh consonants, that hollow ring on calls, footsteps and chatter with nowhere to go. The KK1390 Grid 3D Square Felt Art Panels break up those reflections with a raised square-grid texture, so the room feels softer and more put-together — while reading as a designed feature wall, not a foam patch. Dense polyester felt, self-adhesive backing, up in minutes. No drill, no installer, no mess.
Softens echo — calmer, less hollow room Self-adhesive — no drill, renter-safe Dense PET felt — holds 3D grid, won't fray Peel & press — up in minutes Backed by Arrowzoom's 100-day guarantee Decorative acoustic? Here's the honest version These panels do two jobs. The 3D square-grid surface scatters and lightly absorbs reflections so a hard room sounds less harsh — and the grid texture is the design statement. What they are not is heavy-duty soundproofing or thick studio absorption. For taming overall loudness or bass, pair them with acoustic foam; to stop noise passing between rooms, you need a soundproofing kit. Most great rooms layer: foam at the loud spots, felt art on the walls you actually look at. We'd rather you buy the right thing once than return the wrong one.

NRC (Noise Reduction Coefficient): how much sound a material absorbs. Decorative PET felt typically sits around NRC 0.30–0.55 depending on thickness and the air gap behind it. For comparison, thick premium acoustic foam runs higher (roughly NRC 0.70–0.95) — that's the trade-off between "looks great on the wall" and "maximum absorption." STC (Sound Transmission Class): how much sound a full wall assembly blocks between rooms. STC describes the wall (studs, drywall, insulation), not a panel mounted on it — so no decorative panel, ours included, carries a meaningful STC rating. Honest answer: this panel's job is decorative acoustic — a designed grid surface that scatters and lightly absorbs reflections so your room sounds clearer and looks finished. If your goal is maximum sound absorption or blocking noise between rooms, pair these with our acoustic foam or soundproofing kits. Buy the right tool and you won't be back to return it.

Frequently asked Click any question to expand ↓
Will this soundproof my room? No — and we'd rather tell you straight. This is a decorative acoustic panel: the grid texture scatters and lightly absorbs reflections so the room sounds clearer and less hollow. It does not block noise passing through walls. To stop sound moving between rooms, look at our door kits and soundproofing panels.
What are the panels? Typical panels in this range are about 11.8" × 11.8" (30 × 30 cm), roughly 0.4" (~10 mm) thick at the raised grid. Confirm the exact on the variant you select before you plan your layout.
Will the adhesive damage my paint? On properly cured paint and smooth, clean walls the backing is designed to hold firmly and lift cleanly. If your paint is fresh (under 3 weeks) or chalky, wait or test one panel first. For textured walls, add a little extra mounting tape.
How many panels do I need? For a feature wall behind a desk, bed, or sofa, most people start with 6–9 panels. For a full accent wall, measure the space and plan in 30 cm (11.8") steps to keep the grid even.
Is the felt fire-safe and low-odor? PET felt is low-odor and does not off-gas like some foams. For specific fire-rating requirements (commercial installs), confirm the current test certification with our team before ordering in volume.
Can I cut or trim the panels? Yes — PET felt cuts cleanly with a sharp utility knife and a straightedge. Cut on a protected surface and go slow across the raised grid.
Will they fade or sag over time? High-density PET holds its 3D grid and color indoors away from direct sun. Avoid high-humidity rooms (bathrooms) and prolonged direct sunlight to keep colors true.
Can I mix the different art/style variants? Yes. KK1390–KK1393 share the same 11.8" (30 cm) grid format, so you can mix art/styles across one wall for a custom layout. Dry-lay first to lock the pattern before peeling.
How fast do they ship? Handling is 1–2 business days from our warehouse. Standard shipping arrives in 7–14 days to the US and most countries; express shipping in 7 days or less. worldwide on orders over $99.
