Sleep position
Sleep Number beds are designed to be adjustable, allowing you to change the firmness level of your bed. While there is no single "right" number for a certain type of sleeper, your sleep position can guide you toward a number range that may be more comfortable for you.
Back Sleepers
Back sleepers have more flexibility when it comes to mattress feel since the pressure is more evenly spread across the body. The mattress should fill in the small of the back, providing support and allowing the spine to maintain its natural curve. If you sleep on your back and are experiencing discomfort, Sleep Number recommends increasing your sleep setting by 5-10 points. You can also try placing a pillow under your knees or a small, soft pillow under your lower back.
Side Sleepers
If you sleep on your side, drawing your knees slightly up toward your chest (like a fetal position) can help alleviate pain. Placing a pillow between your knees can also reduce stress on your hips and back. If you're still experiencing discomfort, Sleep Number recommends increasing your sleep setting by 5-10 points.
Stomach Sleepers
Stomach sleeping often gets a bad rap because too much pressure on the abdomen can flatten the spine's natural curve and cause lower back pain. Stomach sleepers typically need a medium-firm mattress—firm enough to support the spine's natural alignment, but soft enough to reduce pressure on the tummy and ribs. If you sleep on your stomach and are experiencing discomfort, Sleep Number recommends decreasing your sleep setting by 5-10 points. You can also try placing a soft pillow under your pelvis or lower abdomen to relieve stomach pressure and release tension in your back.

Aches and pains
Sleep Number beds are designed to help alleviate pain and provide contoured, pressurised support to your body, especially in areas like the back. The Sleep Number setting, which is a number between 1-100, indicates your bed's level of firmness and can be altered to help.
If you are experiencing aches and pains, it can take some time for your body to recover and achieve the full benefits of a good night's sleep. If you are waking up feeling sore or in pain, you may be sleeping at the wrong Sleep Number setting. Even if you've been sleeping at the setting you found in the store, it is recommended to find your Sleep Number setting in your bed, as the environment in your room is different from the store, and the mattress you purchased may be a different model.
There is no one-setting-fits-all for people with back pain. However, there are some guidelines and tips to help with the ache, depending on your sleep position. Side sleeping is considered one of the best positions to protect your back. You can draw your knees slightly up towards your chest, like you're entering a fetal position, and place a pillow between your knees to reduce stress on your hips and back. If you are a back sleeper, try putting a pillow under your knees or a small, soft pillow under your lower back. Stomach sleeping is generally not recommended for people with back pain, as it can cause strain to the back and neck. However, if you cannot sleep any other way, you can place a soft pillow under your pelvis or lower abdomen to relieve some stomach pressure.
If you are still experiencing discomfort, Sleep Number recommends adjusting your sleep setting by 5-10 points. If you have upper back pain, increase your Sleep Number setting by 5-10 points. For lower back pain, decrease your Sleep Number setting by 5-10 points. It is important to note that a mattress will not cure an injury, but it can reduce the discomfort you experience while sleeping.
It is also crucial to talk with your doctor and come up with a plan to address the pain so you can sleep soundly every night.

Sleep tracking
Sleep Number beds are a leading sleep tech brand backed by sleep science researchers and technology specialists. The beds are designed to provide adjustable firmness and integrated sleep tracking to enhance users' sleep quality. The Sleep Number setting is a numeric value that represents the firmness or softness of the bed, which can be adjusted with the click of a button. While there is no single "right" number for a certain type of sleeper, users can experiment with different settings to find what works best for their body and sleep position.
Wearable sleep trackers, such as wristbands or rings, can also help users understand their sleep patterns and improve their sleep quality. These devices can track sleep duration, sleep quality, and sleep phases, providing insights into sleep habits and trends. They can also monitor heart rate, respiratory rate, activity levels, and other lifestyle factors that can affect sleep. While these devices cannot diagnose sleep disorders or measure sleep directly, they can provide valuable information and guidance to improve sleep and overall health.

Mattress thickness
Mattresses come in a variety of thicknesses, ranging from low-profile, slim, standard, thick, and extra-thick. Low-profile mattresses are typically 4 to 8 inches thick and are commonly used in bunk beds, trundle beds, or Murphy beds. Slim mattresses are 8 to 10 inches thick and are suitable for shorter adults, those with mobility issues, and children. Standard mattresses range from 8 to 12 inches in height and can provide an additional comfort layer. Thick mattresses, also known as deep mattresses, are 12 to 14 inches tall and feature a generous comfort layer for improved pressure relief and contouring. Extra-thick mattresses start at 14 inches and can go up to 20 inches or more, offering the most amount of comfort layer.
The ideal mattress thickness depends on various factors, including sleeping position, body weight, bed frame height, and personal preferences. Side sleepers, for instance, typically require thicker mattresses (at least 12 inches) to provide adequate pressure relief for their shoulders and hips. Back sleepers should opt for a mattress between 10 and 12 inches thick to support the natural curvature of the spine. Stomach sleepers should aim for a medium-firmness mattress that is firm enough to maintain spinal alignment while being soft enough to reduce pressure on the tummy and ribs.
Sleep Number, a leading sleep tech brand, offers adjustable mattresses that cater to different budgets and preferences. Their cheapest option, the Classic series, includes the c1, c2, and c4 smart beds, which are on the thinner side at 8 inches tall. The i8 smart bed, priced at $3,999 for a queen size, falls in the middle range. Sleep Number also offers sales and discounts, making their premium mattresses more accessible.
Ultimately, the right mattress thickness depends on your individual needs and preferences. It is important to consider factors such as sleeping position, body weight, and any specific requirements like spinal support or pressure relief.

Sleep trials
Sleep Number recommends testing one setting for three nights, then adjusting it by one or two increments and repeating the process until you find the right level of comfort and support. This process can take a few weeks, as in the case of one reviewer who spent a month testing different levels.
Your sleep number setting will depend on your sleep position and any aches and pains you may be experiencing. For example, stomach sleepers may need a higher sleep number setting to avoid sinking into the mattress, while side sleepers may need a higher number for lower back pain and a lower number for middle or upper back pain. If you experience back pain, drawing your knees up towards your chest and placing a pillow between them can help alleviate discomfort.
Your sleep number setting may also change over time as your body changes. Weight fluctuations, for instance, may require you to adjust your setting by five increments. Similarly, if you start sharing your bed with children or pets, you may need to adjust your setting.
Sleep Number beds come with adjustable air mattresses and various add-ons, such as smart systems, adjustable bases, and different types of comfort foam mattress pads. The cheapest mattress offered by Sleep Number is the Sleep Number c2, which starts at $699 for a twin, while most other offerings reach four digits.

Frequently asked questions
Lie down on your Sleep Number bed in your preferred sleeping position. Adjust your pillow so it feels comfortable. Set the Sleep Number to 100, which is the firmest setting. From there, keep adjusting the number until you feel comfortable in your regular sleeping position.
If you sleep on your back, the mattress should “fill in” the small of your back. Select a Sleep Number that supports your lower back and allows your shoulders and hips to sink slightly into the bed.
If you sleep on your stomach, opt for a firmer Sleep Number setting that supports your back and prevents your stomach from sinking too low into the mattress.
Most Sleep Number beds come with DualAir technology, which allows you and your partner to adjust your side of the bed to your preferred Sleep Number setting.
