Best Mattress for Back Pain (2026): Sleep Number ComfortNext Lux Recognized for Adjustable Support and Lower Back Pressure Relief by Expert Consumers

Sleep Number’s ComfortNext Lux was named Expert Consumers’ 2026 pick for back-pain mattress shoppers, citing adjustable firmness, automatic support, and lower-back pressure relief. The item is a favorable consumer endorsement but provides no quantified sales, margin, or guidance impact. Overall, this is likely limited to modest brand/consumer-demand signaling rather than a near-term financial catalyst.
