Who Should be Interested in Sleep Number Beds?
Sleep Number beds may be right for you if you are looking for a mattress with adjustable firmness. It is also suitable for relieving back pain and can be adjusted independently on both sides. Since the two sides of the bed can be adjusted independently, Sleep Number mattresses are probably best suited to couples.
What Makes These Beds Different
Sleep Number Mattresses use air as the primary method of support allowing the firmness and comfort to be adjusted by pumping in or removing air. Some of the more expensive models feature SleepIQ technology which monitors your movement, breathing and heartrate in order to determine whether you need more or less firmness. It is also possible to adjust each side of the bed independently in order to suit the needs of both partners sharing a bed.
Sleep Number offer mattresses in 3 different product lines – Classic Series, Performance Series and Innovation Series.
These are the lowest priced mattresses available from Sleep Number. As a guide, you can expect to pay around $1000 for a Queen mattress. The thickness of the Classic Series mattresses is generally between 8 and 10 inches and the comfort layers are thinner at 1.5 to 2 inches on most of the models. The classic series is best suited to back or stomach sleepers and they are a great way to get the experience of the Sleep Number technology without having to spend too much money.
Theese mattresses from Sleep Number are a little more expensive than the classic series. As you might expect, the mattresses in this range are thicker and have a more substantial comfort layer making them more suited to side sleepers than the classic series. The performance series also features 5 different comfort zones to help conform to the different parts of the body for the best support while you sleep.
Theese is the most expensive range from Sleep Number. These particular mattresses start at $2,800 and they are the thickest mattresses that Sleep Number has to offer. There are special features built in to these mattresses that you will not find in the other ranges including temperature balancing technology and sleep IQ technology. The innovation range features up to 7 zones of contouring support.
Top 5 Mattresses
Sleep Number CSE
The Sleep Number CSE is the softest mattress in the Classic Series. It is 10 inches thick with a 2 inch comfort layer. The CSE mattress has a 5 zones of comfort layer designed to offer contoured support. The mattress uses DualAir adjustability. It is best suited to back and stomach sleepers, although the addition of a mattress topper will make it more comfortable for side sleepers. The CSE may not be suitable for heavier people due to the thickness only being 10 inches. Like all Sleep Number mattresses, the CSE performs very well in terms of motion isolation and is very fast to break in.
Sleep Number i10
The Sleep Number i10 mattress is part of the Innovation Series product line. It has a dual-layer design that allows you to personalize each side of the bed for your own individual comfort. You can adjust the firmness, comfort and support on each side of the bed. It also features a temperature balancing sleep surface that helps to keep you as cool (or as warm) as you prefer while you sleep. The Sleep Number i10 utilizes SleepIQ technology with sensors inside the bed to track your breathing, your heart rate and your movement. Every morning you can check your SleepIQ score to see how well you slept. This allows you to make adjustments to achieve your perfect sleep. This the only model that is supplied with two remotes as standard.
Sleep number iLE
Like the i10, the Sleep Number iLE is part of the Innovation Series. This 14 inch thick mattress is one of the most advanced mattresses offered by Sleep Number. It features a proprietary foam 3 inch thick comfort layer coupled with dual air adjustability and a temperature balancing technology. Again, similar to the i10 the iLE version also uses SleepIQ technology.
This is a limited edition model and is not a regular feature in the product line. The innovation series models are the ones that rank highest for customer satisfaction. The iLE is great for relieving back pain and it is comfortable for back, stomach and side sleepers. The iLE performs slightly better than the other models in motion isolation tests and due to the thickness of the mattress it is comfortable for heavier people.
Sleep Number C2
The Sleep Number C2 is a medium-firm to firm mattress which is around 8 inches thick and features SleepIQ technology. It is one of the most affordable Sleep Number mattresses. One complaint that some consumers have is that it is not too comfortable for side sleepers unless a mattress topper is added. It is also 8 inches thick, so heavier people or those using a low setting may experience the mattress bottoming out.
Sleep Number C4
The Sleep Number C4 is 10 inches thick including a 1.5 inch thick comfort layer. The C4 uses DualAir adjustability and has 3 separate zones of contouring support. The design of the C4 mattress is somewhat different from the other models because it does not foam borders and the air chambers go all the way to the edges of the bed. This design change means that there is no need to rotate the foam borders. It also seems to have eliminate the common central sagging issue that some consumers have reported with other models. The comfort layer is fairly thin, so side sleepers will need a mattress topper.
Sleep Number has been in business since 1987. The parent company, Select Comfort Corp. have maintained an A+ rating at the Better Business Bureau for a number of years now. However, be aware that there have been more than 840 complaints filed via BBB in the last 3 years which is 3 times as many as most leading mattress manufacturers. It is worth noting that most complaints refer not to the mattresses but rather the customer service or delivery.
Warranties & Return Policy
Sleep Number offer a 25 year limited warranty with their mattresses. However, customers do not rat this warranty particularly highly given that the non-prorated cover lasts only two years from the time of purchase. There is a 100 day trial period and customers who are not satisfied can return the mattress after a minimum of 30 days. Returns get a replacement or a 100% refund minus the cost of shipping.
Questions and Answers:
Do Sleep Number Beds Lose Air?
Around 12% of customers who own a Sleep Number bed say that it does lose air over time. However, in most cases this does seem to be as a result of a faulty air pump, air bladder leak or loose connections. If there is significant air loss from the mattress it can have a negative impact on the comfort and support offered by the mattress thus offering a less restful sleep. It does seem that those experiencing air loss are in the minority and this is not a widespread issue for Sleep Number.
What is Weight Limit?
There is no specific weight limit specified for the Sleep Number mattress and they are designed to adjust firmness levels to accommodate your weight and sleeping position. However, according to consumer opinion some models are not particularly comfortable for heavier individuals, especially side sleepers.
Do these Mattresses Sleep Hot?
Heat retention for Sleep Number beds seems to vary a great deal between the different models. However, overall an average of 6% of Sleep Number customers say that heat retention is significantly troublesome over the summer months and around the same percentage say it sleeps cold in Winter! According to consumers, the heat retention for Sleep Number mattresses does vary depending on which product line they belong to. The classic series performs best, with the performance series coming in a close second. However, ironically the innovation series which is the one with the temperature balancing sleeping surface is known for sleeping hot.
Do These Mattresses Get Dust Mites & Bed Bugs?
Sleep Number recommend that customers buy separate covers for pillows and mattresses to help reduce dust mites. They also suggest unzipping the mattress and vacuuming inside and out on a regular basis. However, beyond that the Sleep Number mattress range has no special features to combat dust mites and bed bugs
Do These Mattresses Stop Snoring?
Sleep Number mattresses themselves do not stop snoring, but they are available with adjustable bases that feature Partner Snore Technology. At the touch of a button you can raise your partner’s head slightly allowing them to breathe easier thus reducing their snoring.
Do These Mattresses Require Additional Accessories?
Additional accessories like a mattress topper are not an essential requirement for Sleep Number beds, but many customers do choose to use one for extra comfort. This is especially true on some of the cheaper models which have a thinner or less substantial comfort layer.
Do These Mattresses Sag?
Mattress sagging is a relatively common complaint among Sleep Number customers. The mattresses are well known for developing a trench or sag in the middle. This is caused by the construction of the beds with the dual air chambers. Customers need to decide if they can live with this potential for sagging in exchange for the benefits of the dual air chambers.
Do These Mattresses Off Gas?
Statistically, Sleep Number mattresses have a higher than average number of reports of off-gassing. The odor is described as a rubbery or chemical smell and in most cases, it lasts for up to 2 weeks. However, some customers say that the smell lasts for much longer with a handful claiming that it never fully goes away.
Are These Mattresses Toxic?
A small percentage of customers (roughly 3%) have reported mold forming between the foam and air chambers. This is something that is well publicized, but it does affect only a small number of customers.
Does it Make Noise?
Traditional mattresses are usually almost completely silent, so customers who are using an airbed like the Sleep Number will likely notice a significant difference in noise. This is because air beds use an electric air pump to adjust firmness and support. As technology has progressed these pumps have become far quieter, but up to 5% of consumers still feel that the pumps are loud enough to make using them during the night impossible. However, for most people the pump is only loud if it is malfunctioning in some way. Aside from the noise from the pump, some customers say that Sleep Number beds produce a rustling, creaking or squeaking noise with movement.
Does it Come with a Headboard?
Sleep Number Beds do not come with a headboard as standard. However, brackets are available to attach one if desired.
