Best Mattress for Side Sleepers 2027

Side sleeping puts uneven pressure on the mattress: the shoulder and hip need to sink in, while the waist needs support to keep the spine's natural curve intact. A mattress that's too firm resists the shoulder and hip; too soft, and everything sinks with no support left for the waist. Zoned construction - found in all-foam and hybrid mattresses - is engineered to do both at once. 

Side sleeping is one of the most common sleep positions, but also one of the most demanding on a mattress. When you lie on your side, your shoulder and hip create significant pressure points, while your waist needs support to keep your spine from sagging. The right mattress for you helps you wake up well-rested and ready for the next day.  

Here's what to actually look for, based on the science. 

Why side sleeping puts different demands on a mattress 

When you sleep on your side, your body doesn't contact the mattress evenly. Your shoulder and hip protrude further than your waist (they need to sink in), while the areas in-between need to push back and keep your spine's natural curve intact. 

A mattress that's too firm won't let your shoulder and hip yield at all, putting pressure on those joints. A mattress that´s too soft makes everything sink equally, leaving your spine unsupported. The right mattress does both at once: pressure points sink, the rest holds in place. 

Zones: the engineering behind side-sleeper support 

Mattresses are built with zones. Zones are different areas engineered to respond differently depending on where your body needs more or less support. The shoulder zone is designed to be softer, allowing the material to contour around your shoulder rather than resist it. The lumbar zone provides firmer support to hold your spine in place. 

This zoning works through cutouts: sections of foam where material is deliberately removed to make that area more responsive. The shoulder area of a side-lying person needs greater deformation, so larger cutouts are used there.  

Most side sleepers find comfort with 5 or 7-zone mattresses, found across the Emma portfolio. 

Emma Original Collection 

Every Emma Original hybrid mattress pairs a pocket spring core with foam comfort layers - giving side sleepers the contouring they need for pressure relief, alongside the zoned support structure that keeps the spine aligned.

Emma Performance Collection 

The Performance Collection is built for those who want Emma's most advanced engineering. Every mattress in the range shares the same core for instant pressure relief - improved Emma AirGrid™ Tech, dual MemoryAdapt foam layers, zoned pocket springs, and a cool-to-touch premium cover - with three height options. 

The improved Emma AirGrid™ Tech and MemoryAdapt layers cushion pressure points, while pocket springs and SupportBase zoning help keep your body aligned for balanced relief and easy movement.
