Side sleepers: prioritize pressure relief without losing support.
Shoulder and hip pressure matter more here, but the right surface still depends on body size, preference and how deeply you like to sink.

NightSoundly does not reduce fit to one label. Sleep position, feel preference, body size, partner needs, room setup and return policy still matter.
What to compare before choosing
For side sleepers, pressure relief is only one part of the decision. Compare how the mattress supports the waist, how easily you can change position, whether the edge feels stable when sitting, and whether the trial gives enough time to adjust. Mattress firmness labels are not standardized, so one brand’s “medium” may feel quite different from another.
Also consider the pillow and mattress together. A softer mattress lets the shoulder sink farther, which can change the pillow loft you need. If you share the bed, add motion isolation, edge support and temperature to the shortlist rather than shopping by sleep position alone.
Use the trial period properly
Pressure relief can feel different after several nights than it does in a showroom or during the first hour at home. Check whether the brand requires a minimum break-in period before a return, and note any pickup or exchange fees. A good trial structure can reduce the risk of choosing the wrong firmness.
Do not ignore edge support
Side sleepers may spend most of the night near the center, but edge stability still matters for sitting, getting in and out of bed and using more of the surface with a partner. Compare it as part of the overall support picture.
