Quell Demi Booth 2+

The Quell Demi Booth 2+ is a compact 2-to-4 person soundproof collaboration booth, designed for offices that need a private meeting space but cannot accommodate the footprint of a full 4-person pod. It uses the same acoustic engineering as the full Quell range — aviation-grade aluminium framing, toughened glass and PET acoustic interior panels — with a slimmer depth profile of just 1.236 m. The Demi is intended for huddle meetings, project standups, two-person video calls and small collaborative sessions.

Both booths seat up to four people and share identical acoustic, ventilation and material engineering. The key difference is depth: the Demi has a 1.236 m external depth, while the full Quell 4 Person Meeting Booth is 2.136 m deep. This makes the Demi a much slimmer 2.72 m² footprint compared with around 4.70 m² for the full 4 Person, so it fits into narrow corridors, against walls or in spaces where a full meeting pod will not. Pod weight is 530 kg for the Demi versus 620–745 kg for the full 4 Person.

The Quell Demi Booth 2+ is independently tested to ISO 23351-1, the international standard for speech-level reduction in acoustic enclosures. Typical office speech is reduced by around 30 dB at the booth wall, meaning conversations inside are effectively inaudible from outside even in busy open-plan environments. The Demi is therefore suitable for confidential huddles, sensitive HR conversations and video calls in shared workspaces.

The Quell Demi Booth uses a dual silent ventilation system — two ultra-quiet Panasonic fans deliver continuous fresh airflow into the booth without disturbing the conversation inside. The fans run automatically while the booth is occupied and continue briefly afterwards to refresh the interior. Motion-activated LED lighting activates on entry and dims when the booth is empty.

Every Quell Demi Booth 2+ includes the acoustic pod (aviation-style alloy frame, toughened glass, PET acoustic interior), dual silent ventilation, motion-activated LED lighting, multiple power points with USB charging, and Bluetooth-connect speaker integration. Furniture options include quality sofas and matching tables sized for the slim Demi profile, with an optional wall-mounted monitor stand (monitor not included).

Internal dimensions are 2.14 m high × 2.04 m wide × 1.20 m deep. External dimensions are 2.30 m high × 2.20 m wide × 1.236 m deep, occupying around 2.72 m² of floor area — a meaningful saving over a full 4-person booth. The pod weighs 530 kg. Allow at least 30 cm clearance behind the booth for the ventilation outlet and around 90 cm in front for the door swing.

Onsite installation by our trained team typically takes two to three hours once the booth is unpacked. The Demi arrives flat-packed in CKD (completely knocked-down) format and is assembled in place. Once installed it is freestanding and connects to a standard 13 A socket. No structural fixings to the floor or ceiling are required, so the booth can be relocated later if your floor plan changes.

The Quell Demi Booth 2+ ships with a 5-year manufacturer warranty covering the structure, glass, electricals and ventilation components. All booths carry CE marking for the UK and EU, and UL listing for the United States, confirming compliance with the applicable electrical-safety and product standards. Replacement parts and after-sales support are coordinated directly through Soundbox Store.

We deliver and install the Quell Demi Booth 2+ throughout the United Kingdom, the European Union, the United States, the United Arab Emirates and Switzerland. UK and EU lead times are typically 4–6 weeks from order; US, UAE and Swiss orders are 6–8 weeks. Installation by our trained team is included as standard for UK and EU deliveries, with options available for other regions.

No. Our booths are plug-and-play — a ~2m power cable runs from the side of the booth into a standard wall socket. The plug is supplied to match your delivery region for the United States with UL Listed components. No special voltage, dedicated circuit, or electrician required.

Our meeting and phone booths require simple installation, we recommend using our professional installation team. Each booth features a built-in power inlet on the side with an integrated 13-amp fused spur. Once assembled, the included 2-metre cable simply plugs into a standard mains socket, making setup simple.
