Emma Hybrid Airgrid Mattress

This is the mattress most UK review sites name first for side sleepers, and the reason is the AirGrid layer: a flexible grid of open air pockets Emma says flexes locally under a shoulder or hip while springing back as you turn. Reviewers report it cushions the shoulder and hip without the whole-body sink of memory foam, and the removable, washable cover plus open-cell structure help it sleep cool. On feel, Emma rates it 8 out of 10 on its own scale — where 1 is firmest and 10 softest — so this is a medium-soft, cushioning bed (Emma nudged the rating up from 7.5 to 8 to match owner expectations). Reviewers say that soft surface suits lighter and average side sleepers best, while heavier builds and front sleepers can sink too far and are better served by the firmer support of the Simba Hybrid Pro or OTTY below. Against the Simba Hybrid Pro at number two you gain plusher, more localised cushioning at the shoulder and usually a lower price, but give up the Pro's deeper zoned spring support. Note it is also sold in the UK from early 2026 as the Emma Original Elite.
