What You Need to Know about Sleep Number Mattresses

Mattress Types and Components:

  • Sleep Number offers airbed mattresses. All Sleep Number models feature two air chambers in the support core, and a signature ‘Firmness Control’ system that allows owners to adjust the air pressure of the mattress; an electrical outlet is required to operate this system.
  • The company’s 10 available mattress models are divided into five different product series that vary by composition, thickness, and price-point:
    • Classic: The Classic series currently includes two models: the c2 and the c4. The c2 is designed without a comfort layer, while the c4 is constructed with a polyfoam comfort layer. Sleep Number Classic mattresses also come with covers woven from rayon and polypropylene (c2) or polyester and polypropylene (c4).
    • Performance: The Performance series currently includes two models: the p5 and the p6. These mattresses feature polyfoam comfort layers. The p5 cover is woven from a blend of rayon and polypropylene, and the p6 cover is woven from a blend of polyester and rayon.
    • Innovation: The Innovation series consists of four models: the i7, i8, i10, and iLE. The i8 and iLE models are constructed with polyfoam comfort layers; the i7 features a memory foam comfort layer; and the i10 is designed for flipping with a reversible top comfort layer of memory foam and a second comfort layer of polyfoam. All four models feature covers woven from a blend of polyester and polypropylene. The i7 and i10 models are also featured in Sleep Number’s Smart Bed collection due to the SleepIQ, an optional sleep monitor built into the mattress that is designed to track the sleeper’s breathing, heart rate, and movements during the night.
    • Memory Foam: This series includes one model: the m7. The m7 features a memory foam comfort layer and a mattress cover is woven from a blend of polyester and rayon.
    • it bed: Sleep Number’s newest design, the it bed is constructed with a polyfoam comfort layer. This model comes with a cover woven from a blend of polyester and elastane.

Pros:

  • Sleep Number offers five different mattress types and a total of 10 mattress models in order to accommodate a wide range of sleepers.
  • Adjustable controls allow sleepers to customize air pressure based on their preferred position and firmness rating.
  • For an extra fee, Sleep Number’s Comfort Services Home Delivery option involves trained technicians delivering and fully assembling the mattress.
  • Sleep Number mattresses produce no off-gassing, and offer above-average conforming and pressure relief compared to other airbed models, but not compared to other mattress types.

Cons:

  • Sleep Number mattresses tend to degrade faster than other mattress models, due to both the foam-based comfort layers and air chambers that are prone to leaks and equipment malfunctions.
  • The price-point for Sleep Number mattresses is relatively high compared to other mattress models.
  • Customers will not be eligible to return their mattress until 30 days after the original purchase, and their product refund will not include shipping and delivery fees.
  • Sleep Number’s 25-year warranty includes two years of nonprorated coverage, and customers could face relatively expensive repair or replacement costs due to the high price-point of the mattresses.

Products and Price Range: Sleep Number mattresses are available in eight sizes: Twin, Twin Long or XL (same dimensions), Full, Double, Queen, King, and California King. In addition to standard King and California King mattresses, these sizes are available in two other designs. The split King and California King models are divided down the middle, allowing sleepers on either side to adjust the head and foot height; and the FlexTop King and California King designs are split at the head, allowing sleepers to adjust the head height while sharing a uniform foot surface. Sleep Number mattresses range in price based on the selected model (see table in next section for more information).

How Are the Mattresses Shipped?: Sleep Number mattresses are vacuum-sealed and shipped in a box. They are delivered without air in the chambers; owners must set up the mattress with the Firmness Control system plugged into an electrical outlet in order to introduce air into the chambers.
Where Do They Ship?: Sleep Number ships most mattresses to all 50 U.S. states, as well as Puerto Rico and the U.S. Virgin Islands. However, please note that deliveries of the it bed are limited to the contiguous 48 states.
Delivery Fee: Standard deliveries shipped through UPS Ground will be $89.99 for all Sleep Number mattresses except for the it bed, which will be shipped with no charge. Customers may also choose the ‘Comfort Services Home Delivery’ option, which includes home delivery and full assembly performed by Sleep Number technicians. This service is available for $179.99 per mattress.

Delivery Policy: The delivery policy for Sleep Number is as follows:

  1. At the time of purchase, customers select whether they would prefer UPS Ground or Comfort Services Home Delivery. Comfort Services Home Delivery is not available for the it bed, but this model is the only Sleep Number mattress that will not incur a delivery fee through UPS Ground.
  2. UPS Ground deliveries are available in all 50 states, as well as Puerto Rico and the U.S. Virgin Islands. Comfort Services Home Delivery is available in all states except Hawaii, but customers who live outside Sleep Number’s ‘standard delivery areas’ may be required to pay an additional fee.

  4. Customers must ensure their mattress will be set up near an electrical outlet in order to operate the Firmness Control system that adjusts air pressure in the mattress.

Old Mattress Removal: Deliveries shipped through UPS Ground do not offer old mattress removal services. The Comfort Services Home Delivery option includes removal and disposal of the customer’s existing mattress.
Availability: Sleep Number mattresses are exclusively available through Sleep Number.

Sleep Trial and Warranty Information

Trial Period and Guarantee: Sleep Number offers a 100-night sleep trial on all Classic, Performance, Innovation, and Memory Foam Series mattresses, and a 30-night sleep trial for the it bed.

  1. The 100-night trial begins on the original date of purchase, but customers will not be able to return the mattress until 30 nights have elapsed.
  2. Although a full refund will be issued on all returned Sleep Number mattresses, customers will still be required to pay all applicable return shipping and delivery fees.
  3. Customers who wish to return their mattress must contact the Sleep Number customer service center and request a Return Service Order (RSO) number. Only those with a valid RSO number will be allowed to coordinate a mattress return. Authorized returns must be received within 30 days.
  4. As soon as Sleep Number has received and inspected the condition of the returned mattress, a refund of the original purchase price of the mattress minus shipping and delivery fees will be issued to the original method of payment within 21 days.
  5. For the it bed: the 30-night sleep trial begins on the original date of purchase. Customers who wish to return this mattress within the trial period must pay a delivery fee of $99.

Warranty: Sleep Number offers a 25-year limited mattress warranty on all mattresses in the Classic, Performance, Innovation, and Memory Foam Series. According to the Sleep Number website, these warranty terms apply to all mattresses that have been available for purchase since March 27, 2013. Additionally, a two-year limited nonprorated warranty is available for the it bed.

  1. The Sleep Number warranty for Classic, Performance, Innovation, and Memory Foam Series mattresses is divided into nonprorated and prorated coverage periods.
    • The first two years of coverage are nonprorated, and all defective mattresses will be repaired or replaced at no additional expense to the owner (including shipping and replacement parts).
    • During years 3 to 19, mattress owners will receive prorated coverage. Defective mattresses and parts will be replaced at a rate of 20% the original cost, plus an additional 4% for year that has passed since the original purchase. This means that repairs will cost 28% of the original cost during the third year of ownership, 32% of the original cost during the fourth year, etc.
    • During years 20 to 25, owners will receive prorated coverage. They may replace mattresses and parts at a rate of 96% of the original cost.
  2. The warranty for it bed mattresses will cover all costs for repairing or replacing the mattress for a period of two years after the original purchase, including shipping and delivery fees.
  3. The Sleep Number mattress warranties will not cover the following defects:
    • Defects that result from ‘normal wear and tear’, including ‘mattress cover compression, bunching, foam compression, or discoloration of components’.
    • Damage that results from either tampering with the mattress or opening the Firmness Control system.
    • Any form of damage that does not occur during the manufacturing or shipping processes, including damage caused by laundering or dry cleaning.
    • Damage that occurs due to ‘acts of nature’, such as lightning strikes, fires, or floods.
    • Damage that is caused by improper foundational support. According to Sleep Number, these mattresses require a firm, solid, non–spring foundation or adjustable bed base that is sufficiently strong and stable so as being capable of supporting the weight of the mattress and its occupants’.
  4. The warranty coverage extends exclusively to the original purchaser as long as the mattress is only used in the U.S. Those who purchase or acquire the mattress from the original owner will do so ‘as is’, and will not receive warranty coverage. The warranty will be voided if the mattress leaves the U.S.
 

Sleep Number Mattress Sleep Ratings

CategoryCriteriaSleep Number RatingWhat Sleep Number Users Say
Customer SatisfactionBased on data collection, this is an overall customer sentiment regarding Sleep Number mattresses.78% to 81%Sleep Number mattresses have received above-average satisfaction ratings across the board, due in part to the wide available selection and adjustable air pressure and firmness settings.
Durability Airbeds tend to have shorter lifespans than other mattresses, due to both the foam-based comfort layers and air chambers that may break or wear out somewhat quickly.FairOwner reports indicate that Sleep Number mattresses tend to wear out faster than other models. Foam degradation and leaky air chambers are two of the most common complaints.
Motion IsolationAirbeds with memory foam may reduce motion transfer to some extent, but most models produce a fair amount of motion. GoodCustomers note that Sleep Number mattresses tend to minimize motion transfer, particularly the i7, i10, and m7 memory foam models.
Sex Airbeds are somewhat responsive and can be suitable for sex, but this often comes down to specific construction.    FairSleep Number airbeds are designed with a small trench between the air chambers that runs the middle of the mattress, creating a non-uniform surface that some owners claim is less than ideal for sex.
ConformingAirbeds may contour to the sleeper’s figure and alleviate pressure points, but these mattresses tend to conform less than latex or memory foam models. GoodConforming ability depends on the selected Sleep Number model, but owners claim that the c4, i7, i10, and m7 conform the closest and offer the highest levels of pressure relief.
Temperature NeutralityIn terms of body heat retention, airbeds tend to fall between innersprings (which sleep relatively cool) and memory foam mattresses (which are known for sleeping hot)FairSleep Number owners claim that the Classic and Performance Series mattresses sleep the coolest, while the Performance and Memory Foam models tend to sleep the warmest.
Edge SupportAirbeds usually offer more edge support than latex or memory foam mattresses, but this will depend on how the air chambers are constructed and reinforced.FairSleep Number customers say the mattresses offer minimal edge support, giving them a slight advantage over memory foam and latex models.
NoiseAirbeds tend to produce more noise than other mattress types due to the electrical pump components.FairSleep Number owners claim that the Firmness Control system produces a fair amount of noise when air pressure levels are adjusted, but the mattress itself is fairly quiet.
Ease of Moving and RotatingWhen properly deflated, airbeds are usually much lighter than other mattress types. GoodMost Sleep Number mattresses weigh between 50 and 90 pounds, and only one model – the reversible i10 – is designed for flipping.
