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

NEW YORK, Sept. 1, 2026 /PRNewswire/ -- Expert Consumers has named the Sleep Number ComfortNext Lux its 2026 choice for people researching mattresses for back pain. The assessment centers on the mattress's adjustable firmness, automatic support, and pressure relief for the lower back and other sensitive areas.

Best Mattress for Back Pain

• Sleep Number - a sleep technology company offering adjustable mattresses with personalized firmness and support

The recognition addresses a common difficulty in mattress shopping: firmness needs can vary by sleeper, sleep posture, physical condition, and even from one night to another. Instead of requiring the owner to commit to a fixed firmness level, ComfortNext Lux provides adjustability that can be personalized over time.

Why ComfortNext Lux?

ComfortNext Lux is a 13-inch mattress from Sleep Number's ComfortNext collection. It uses a Tri-Brid design with high-density foam, microcoils, and adjustable air support. These elements are intended to provide cushioning while maintaining support beneath the body.

Its primary specifications include:

• Adjustable firmness
• Pressure relief for the hips, shoulders, knees, and lower back
• Microcoils for added support
• Built-in cooling materials with enhanced airflow
• Responsive Air technology
• App-based controls and personalized sleep insights

The mattress provides superior relief for the hips, shoulders, knees, and lower back. It sits between the 12-inch ComfortNext and 14-inch ComfortNext Ultra within the collection. Sleep Number's ComfortNext collection lists three models with varying amounts of cushioning, airflow, and pressure relief.

How Does Adjustable Firmness Support Different Sleep Needs?

All Sleep Number mattresses allow firmness adjustments. Queen sizes and larger provide separate controls for each side, allowing two sleepers to use different settings. Smaller sizes use one adjustable chamber.

This arrangement may be useful when partners have different body types or firmness preferences. One person can select a softer setting for added cushioning, while the other can choose a firmer setting for more support. Each side can also be changed later without replacing the mattress.

Responsive Air technology adds automatic adjustments during the night. The system responds to changes in sleeping posture and modifies firmness to help maintain consistent support as the sleeper turns or changes sides.

How Does ComfortNext Lux Address Lower Back Pressure?

Pressure relief and firmness are closely connected to how a mattress feels beneath the lower back. A surface that feels too soft may allow parts of the body to settle more deeply, while an overly firm surface may feel uncomfortable around sensitive areas.

ComfortNext Lux lets sleepers test different settings instead of relying on one factory-set feel. Its high-density foam supplies cushioning, while microcoils add support within the 13-inch construction. The adjustable air system then allows further firmness changes based on personal comfort.

The mattress is intended to support multiple sleeping postures. Side sleepers can use a softer setting for cushioning around the hips and shoulders, while back or stomach sleepers can select a firmer setting.

What Other Features Are Included?

ComfortNext Lux uses built-in cooling materials and enhanced airflow. Sleep Number currently describes the model as containing 67% more built-in cooling materials than the ComfortMode mattress.

ComfortNext Lux is controlled through the Sleep Number app, which also provides personalized sleep insights each morning. Compatible foundations and adjustable bases are sold separately.

The mattress includes a 100-night home trial and a 10-year limited warranty. Sleep Number mattresses undergo durability testing designed around a 25-year lifespan.

What Is the Main Takeaway?

ComfortNext Lux offers a flexible alternative to fixed-firmness mattresses. Its adjustable air system, Responsive Air technology, microcoil support, and lower-back pressure relief accommodate different sleep positions and comfort preferences. Dual-side controls in queen sizes and larger also give couples separate firmness settings. This adaptable design forms the basis of Expert Consumers' 2026 recognition.
