WIRED Reviews Releases 2026 Guide to Top Mattresses for Side Sleepers
The new report, led by certified sleep science coach Julia Forbes and director Martin Cizmar, advises buyers to opt for hybrid constructions and the firmest tolerable mattress before adding a topper.
WIRED Reviews has published a comprehensive guide identifying twelve top mattresses specifically designed for side sleepers. The selection process, guided by certified sleep science coach Julia Forbes and director Martin Cizmar, prioritises critical performance factors including lumbar support, pressure relief for hips and shoulders, and spinal alignment. The report highlights that between half and three-quarters of the population sleep on their side, making these specific ergonomic requirements essential for maintaining back health during the night.
The guide names the Nolah Evolution as the top tested pick, noting its ability to balance pressure relief with necessary support. Following the Nolah Evolution, the Helix Midnight Luxe, Bear Elite Hybrid, Leesa Sapira Chill Hybrid, Naturepedic EOS, Saatva Contour5, Casper Dream Hybrid, Birch Luxe Natural, WinkBed, Wolf Memory Foam Hybrid, Sonu Sleep System, and the Sleep Number ComfortNext Lux were also selected as strong contenders. Each model was subjected to multi-week trials and sleep tracking to verify its ability to keep the sleeper comfortable without causing joint strain.
A key recommendation in the report is the preference for hybrid constructions over all-foam options. The editors explain that while memory foam offers a plush feel, it can compress excessively over time, leading to poor support and overheating. Hybrid mattresses, which combine foam layers with pocketed coils, are favoured because the springs prevent the foam from compacting too much, ensuring consistent support throughout the night and helping to dissipate body heat.
Regarding firmness, the guide advises side sleepers to choose the firmest mattress they can tolerate rather than seeking out the softest option available. The rationale is that a mattress that is too soft can cause the hips and shoulders to sink too deeply, throwing the spine out of alignment. The report suggests that if a high-quality mattress feels too firm, it is easier and more effective to add a soft topper to achieve the desired cushioning than to attempt to firm up a mattress that is already too soft.
The twelve selected models range from organic hybrids like the Naturepedic EOS and Birch Luxe Natural to smart beds like the Sleep Number ComfortNext Lux, which features built-in sleep tracking to help users dial in their preferred firmness. Prices for the reviewed models vary significantly, with twin sizes starting around $1,049 for the Wolf Memory Foam Hybrid and reaching up to $4,700 for the Personal Comfort Rejuvenate in the honorable mentions section.
The publication of this guide marks WIRED Reviews continued effort to help consumers navigate the expanding bed-in-a-box market. By focusing on specific physiological needs of side sleepers, the report aims to provide actionable advice for those seeking to prevent lower back pain and ensure restful sleep through proper spinal alignment and pressure distribution.
