What You'll Learn

Sleep Number mattresses are adjustable
The Sleep Number C2 mattress has been described as having "widely variable sinkage levels" and "20% more bounce than the average level". At a sleep number of 5, there is so little air in the chambers that the body effectively sinks through the foam layers and into the foundation of the mattress. Conversely, higher sleep numbers create more support, although this also means firmer support.
The level of support provided by the mattress is therefore dependent on the sleep number setting. This adjustability means that Sleep Number mattresses can accommodate a wide range of sleeper weights and preferences. For example, heavier sleepers tend to require more support, which can be provided by a higher sleep number. However, some sleepers may find that even the highest sleep number does not provide enough support.
The adjustability of Sleep Number mattresses also means that they can accommodate couples with different firmness preferences. For example, one person may prefer a firmer mattress, while another may prefer a softer mattress. A split king mattress allows each person to adjust their side of the bed to their desired level of firmness.

They offer good value for money
Sleep Number mattresses are reasonably priced and offer good value for money. While they are not the cheapest option on the market, they are packed with sleep-revolutionizing technology, such as smart cooling systems, adjustable firmness, and sleep tracking sensors. The different series cater to different budgets, with the Classic series being the most affordable option.
The Sleep Number mattresses also have layers of foam for added comfort and to prevent sinking too deeply into the mattress. The Performance Series, for example, offers 4 to 5 inches of cushioning, with the p6 model providing an additional inch for a total thickness of 11 inches. This extra cushioning can be a significant advantage, especially for those who prefer a softer mattress.
Additionally, Sleep Number mattresses provide excellent customer service, with free delivery, setup, and removal of your old mattress. They also often have promotions and discounts available, making their products even more affordable. For example, they currently offer up to $1,000 off queen, king, and Cal king-sized mattresses, with even higher discounts on certain models and when paired with a smart bed base.
When compared to other premium brands, Sleep Number mattresses offer exceptional value. They are adjustable air beds with chambers that can be inflated or deflated to reach the desired firmness, catering to various preferences and providing a personalized sleep experience. This adjustability also extends to their bed bases, which can be beneficial for those with back pain or achy joints.
While some users have expressed that the mattresses may not be as comfortable as expected, especially for heavier individuals, the ability to customize the firmness and add mattress toppers can address these concerns. Overall, Sleep Number mattresses provide a good balance between price and the features offered, making them a worthwhile investment for those seeking a high-quality, adjustable, and technologically advanced sleeping solution.

Some find the rubber bladder uncomfortable
Sleep Number mattresses are adjustable air beds built with chambers that you can inflate and deflate to reach your desired firmness. They also have layers of foam for extra comfort. However, some users have found that the rubber bladder, which is the support layer of the mattress, is uncomfortable. This is likely a design issue that even higher-end adjustable mattresses may struggle with. The rubber bladder doesn't provide much pressure relief, and some sleepers have complained about a lack of cushioning, describing the mattress as too firm or too thin.
The Sleep Number p5 Smart Bed offers enhanced pressure relief around the shoulders and hips, with plush layers for soothing sleep. The Sleep Number m7 Smart Bed is the company's only memory foam smart mattress, offering more cushioning, contouring, and pressure relief than other models. Despite these offerings, some sleepers may still find the rubber bladder uncomfortable, especially if they prefer a softer mattress.
The amount of air in the bladder also affects the level of support provided by the mattress. A sleep number of 5, for example, has so little air that the sleeper may sink into the mattress and feel a lack of support. This can be adjusted to personal preference, but it highlights the potential issue of inadequate pressure relief, especially for heavier sleepers.
Some sleepers have added mattress toppers to their Sleep Number mattresses to increase cushioning and comfort. However, this can be an additional expense, and it may not always stay in place or work with the adjustable bed frame features, such as the foot-warming function. While mattress toppers can help address the issue of a lack of cushioning, they don't change the feel of the rubber bladder, which some may still find uncomfortable.
Overall, while Sleep Number mattresses offer adjustability and smart features, the rubber bladder may not suit everyone's preferences, especially those who prioritize a soft and billowy mattress.

They have a wide range of models
Sleep Number mattresses are adjustable air beds with several layers of foam for added comfort. The firmness of the mattress can be adjusted using a mobile app, and the company offers a wide range of models to cater to different budgets and preferences.
The Classic series is the cheapest option, including the c1, c2, and c4 smart beds. The c2 model has average pricing for an adjustable mattress and offers better-than-average cooling, faster response time, improved edge support, and better sex performance. However, it has variable sinkage levels and more bounce than average.

The Performance series is slightly more expensive and plush than the Classic series. The p5 and pSE models offer 4 inches of cushioning with a total height of 10 inches. The p6, the company's most popular mattress, has an additional inch of cushioning, measuring 11 inches in total thickness.
