Emma Sleep launches new 'anti-heatwave' mattress range — and they're up to £500 off in the brand's big summer sale
The Performance mattress range, starting from £549 in the Emma sale, uses Emma's breathable AirGrid technology to keep you cooler even when another heatwave inevitably hits.The Emma AirGrid is found in one of the best mattresses we've tested; the Emma Original Elite (formerly the Emma Hybrid AirGrid). Our tester credited the AirGrid with the plush, contouring feel that made the Original Elite so comfortable for side sleepers, as well as its breathable feel "even on warmer days."So why not stick with the Original collection? Emma's new Performance mattress range aims to take the comfort of the Original and turn it up a notch, meaning more cushioning, enhanced support and better airflow... but that also means boosting the prices.
