How they stack up: These are the most (and least) liked mattresses, according to J.D. Power

The fierce competition in the mattress industry has led to bankruptcies, zero-interest financing deals, discounting, new technology and legal battles.

But amid the chaos, people who bought a mattress within the last 12 months are growing happier.

The 2019 J.D. Power Mattress Satisfaction Report, released Wednesday, found that overall satisfaction with mattresses rose eight points on a 1,000-point scale, compared with a year earlier.

Consumers ranked their priorities, in order, as comfort, price, support, durability, warranty, feature variety and customer service. In each area, they were more satisfied in 2019, J.D. Power reported, based on 1,847 responses.

Among retail mattresses, Tempur Sealy International’s Tempur-Pedic mattress ranked first in customer satisfaction.

But the company’s Sealy brand ranked last among seven included in the survey.
