Coway announced on September 30 that it had ranked first in the water purifier, mattress, and bidet categories of the 2026 Korea Customer Satisfaction Index (KCSI) survey, which is organized by Korea Management Association Consulting.

The Korea Customer Satisfaction Index survey is a metric that measures customer satisfaction with products and services across industries. Through individual consumer interviews, it determines and announces the most preferred companies and products among customers.

In this year’s survey, Coway achieved first place by earning the highest scores for 10 consecutive years in the water purifier category, 6 years in a row in the mattress category, and 2 consecutive years in the bidet category. In the water purifier section, Coway received high marks for offering a full lineup of five ice water purifiers, expanding choices to suit diverse customer lifestyles ranging from ultra-compact designs to large-capacity ice makers and coffee extraction features.

In the mattress category, BEREX-brand sleep tech innovations were highly praised for driving customer satisfaction. Customized sleep solutions, such as the “M Series Massage Mattress Bed” and the “R Series Stretching Motion Bed,” added massage and stretching functions to mattresses to address not only restful sleep but also overall relaxation and recovery—creating new customer value.

In the bidet category, the “Lulu Themanner Bidet Plus” stood out as the only domestic bidet with a particle suction feature, earning high scores. It powerfully suctions fine water droplets and bacteria created when flushing the toilet, with the absorbed air undergoing UV sterilization and safe clean filtration to achieve 99.9% sterilization.

A Coway representative stated, “We will continue to enhance our technological innovation and user convenience to deliver differentiated value to our customers’ daily lives.”
