NEW YORK, Oct. 9, 2026 /PRNewswire/ -- Better Business Advice has recognized Sleep Number as a top choice for personalized adjustable comfort in its 2026 guide to the best adjustable mattresses. Every Sleep Number mattress allows sleepers to make the bed firmer or softer as their comfort needs change.

Best Adjustable Mattress

• Sleep Number - known for adjustable mattresses that let sleepers choose how firm or soft the bed feels, with options for added cushioning, cooling, temperature control, and smart features.

A mattress may feel comfortable during a short showroom visit but different after several nights at home. Sleeping position, physical activity, soreness, room temperature, and personal preferences can all affect how a bed feels over time.

Sleep Number mattresses address this challenge with adjustable air chambers. Sleepers can add air for a firmer feel or release air for a softer feel instead of remaining limited to the firmness selected at the time of purchase.

The current Sleep Number range includes seven mattresses in the ComfortMode, ComfortNext, and Climate collections. Adjustable firmness is included across the entire range. Differences in cushioning, pressure relief, cooling, temperature control, mattress height, and connected features help consumers choose the model that fits their needs.

Personalized Firmness Levels

Every Sleep Number mattress allows sleepers to adjust how firm or soft the bed feels. The firmness can be changed without adding a mattress topper, rearranging foam layers, or replacing the mattress.

This flexibility may be helpful because comfort preferences do not always stay the same. A setting that feels comfortable for back sleeping may not provide the same comfort after switching to side sleeping. Exercise, temporary soreness, pregnancy, injury, and weight changes may also affect how much cushioning or support feels right.

Sleep Number recommends making small adjustments and sleeping at a new setting for several nights before changing it again. This gives the body time to settle into the new firmness level.

Compatible mattresses also offer Responsive Air technology. The feature notices changes caused by movement, sleeping position, and temperature, then makes small adjustments to help maintain the selected firmness during the night. Sleepers can still make their own changes whenever they want the bed to feel noticeably firmer or softer.

The method used to control the mattress depends on the collection. ComfortMode mattresses use a compatible remote and do not require Wi-Fi or an app. Compatible ComfortNext and Climate mattresses can be controlled through the Sleep Number app. Remote availability depends on the selected mattress and setup.

Each Person Can Adjust Their Side of the Bed

Couples often prefer different levels of firmness. One person may want a softer surface, while the other may feel more comfortable with firmer support.

Queen-size and larger Sleep Number mattresses can give each person a separate firmness setting. Each sleeper can adjust their side of the bed without changing how the other side feels.

This can be useful when sleeping positions or comfort preferences differ. A side sleeper may prefer more cushioning around the shoulders and hips. A back or stomach sleeper may want a firmer surface. With separate settings, neither person has to settle for one firmness level across the entire mattress.

The separate air chambers may also reduce how much movement is felt across the bed when one person turns over or gets up. The amount of movement felt will still depend on the sleeper, mattress, and base, so the feature does not guarantee complete motion isolation.

Separate settings can remain useful even when both sleepers initially choose similar firmness levels. Temporary soreness, a change in physical activity, or a new sleeping position may cause one person to want a different feel later. Each side can be adjusted whenever those needs change.

Seven Mattresses Across Three Collections

The current Sleep Number portfolio includes seven models divided among the ComfortMode, ComfortNext, and Climate collections. Every model offers adjustable firmness, but the amount of cushioning, cooling, pressure relief, and temperature control varies.

ComfortMode includes 10-inch and 11-inch mattresses. Both combine adjustable firmness with supportive foam and built-in cooling materials. They use remote controls, making them suitable for consumers who want a more straightforward way to adjust the mattress without depending on an app.

ComfortNext includes 12-inch, 13-inch, and 14-inch mattresses. As the mattresses become taller, they provide more cushioning, pressure relief, cooling material, and airflow. Select ComfortNext models combine adjustable air support with foam and small coils to create a more cushioned, traditional mattress feel.

The Climate collection focuses on temperature control. ClimateCool can actively cool each side of the bed while also providing adjustable firmness and Responsive Air technology.

Climate360 can both cool and warm each side separately. This may be especially helpful for couples when one person tends to sleep hot and the other prefers a warmer bed.

Choosing an Adjustable Mattress for Long-Term Use

Choosing a Sleep Number mattress involves more than selecting a firmness level. Since every model offers adjustable firmness, consumers can compare the mattresses based on cushioning, pressure relief, cooling, temperature control, mattress height, and preferred controls.

ComfortMode mattresses may suit sleepers who want adjustable firmness with a simpler setup and a more direct, supportive feel. ComfortNext models provide deeper cushioning and more pressure relief, which may appeal to side sleepers or anyone who prefers a taller mattress.

Mattress height ranges from 10 to 14 inches across the collection. This can affect the overall height of the bed and the type of fitted sheets needed.

Temperature preferences are another consideration. Built-in cooling materials may be enough for sleepers who only become warm occasionally. ClimateCool provides active cooling for those who regularly sleep hot. Climate360 offers the widest range of temperature choices by allowing each side to be cooled or warmed separately.

The mattress also needs a firm, flat surface that can evenly support the adjustable air chambers. A traditional box spring does not provide the required support. Suitable options include a compatible Sleep Number base, an appropriate platform bed, or bed slats placed no more than two inches apart.

An adjustable mattress and an adjustable base perform different functions. The mattress changes how firm or soft the sleeping surface feels. An adjustable base changes the position of the bed by raising areas such as the head or feet. The two can be used together, but an adjustable base is not required to change the mattress firmness.

Sleep Number received recognition from Better Business Advice because adjustable firmness is available throughout the mattress range rather than being limited to one model. The right choice will depend on the amount of cushioning, pressure relief, temperature control, mattress height, and connected features each sleeper wants.
