A Safe, Peaceful Sleep Sanctuary for EveryoneCapsule beds of Kotobuki SeatingSleep Capsule

The world's first capsule hotel was built in Osaka, Japan in 1979 and fitted with Kotobuki's ultra-modern sleep capsules. Since then, the appeal of a convenient and cost-effective sleep solution has soared in Japan and in an increasing number of other countries.
Technologically-forward Japanese design has developed cocoons to deliver the level of comfort you'd expect from a hotel and function for a wide range of businesses and customers, while maximising space efficiency, and low-cost cleaning and maintenance for the operator.

Product Features

Sleep capsules are precision engineered for sound and thermal insulating properties. As with the full range of Kotobuki products, the capsules offer high durability, reassuring customers of a safe, secure sleep environment.

From a large hotel with hundreds of beds to a small hotel with dozens of beds

Flexible and Scalable

Sleep capsules are now being used not just as flexible hotel solutions, but also across a wide range of industries. Pioneered for business overnighters, a range of businesses and institutions recognise the benefits of restful sleep opportunities for shift workers, hospital and care staff, emergency services staff, the aviation industry and many more. From a single capsule bed in a care home, to safe, secure banks of beds in hostels, we offer a flexible, scalable solution.

The best nap for people who work at airports, police stations, hospitals, a fire stations, etc.

Well rested employees, effective employees

Critical staff often work long shifts and difficult hours. Sleep Capsules provide a quiet, isolated environment to maximise the value of down-time. The Sleep Capsule is increasingly being installed in hospitals, airports, police stations and any organisations in use 24 hours.

Multiple layout variations to meet requirements

Modular units provide flexible options

Multiple layout options offer a solution specifically tailored to individual needs. Space-efficient modules can maximise customer numbers, while larger, more spacious units offer a more luxurious experience in an efficient space.

Privacy is maintained even when many people use the facility

Comfort and Privacy

Sleep capsules are designed and orientated for optimal privacy. Soundproofing and ventilation have been developed in partnership to ensure that each capsule is comfortable and airy while not compromising their discrete nature.

Easily-maintained safe space equipped with a high fire-resistant property

Low Maintenance, High Safety

Cleaning and maintenance of the capsules is vastly easier and cheaper than with a standard hotel room. Walls are smooth and scratch-resistant, free from any protrusions such as nails or screws. Fireproof aluminium panels are used for wall and ceiling materials inside the unit, providing a high level of fire-safety.
