Things to Consider When Picking A Mattress

Firmness / Feel

Sleep Number beds can be adjusted to multiple levels of different firmness, but most people find comfort in the medium firmness range. The comfort foam layer plus the collection of air chambers incorporated into the mattress make this ideal for hot sleepers who like to rest on their sides and backs.

Motion Isolation

Couples that share a bed find it frustrating when their partner tosses and turns because of the motion transfer. Tempur-Pedic beds, which incorporate memory foam, are known for their motion isolation, meaning less disturbance for sleeping couples. Sleep Number beds make some of the best mattresses for couples by allowing them to personalize their firmness on each side with two separate mattresses, so motion transfer is almost nonexistent. 

Edge Support

Edge Support is an important factor to consider for people who have trouble getting in or out of bed. Tempur-Pedic beds with spring coils have much more spring support, providing providing much greater edge support, than their pure memory foam counterparts. Sleep Number mattresses can vary with their edge support depending on the level of inflation in the air chambers, but beds with thicker top layers tend to have less-than-favorable edge support.

Pressure Relief 

Tempur-Pedic mattresses and their memory foam construction have excellent contouring properties, meaning reduced pain in pressure points and increased pressure relief. Sleep Number beds with thicker comfort layers have been reported as offering better responsiveness and relief from pressure points, but Tempur-Pedic is ultimately the better option.

Spine Alignment 

Tempur-Pedic mattresses’ responsiveness promotes healthy spine alignment, resulting in less stress on pressure points and a much better sleep. Sleep Number’s customizable firmness allows for optimal spine alignment. Check out our list on the best mattress for stomach sleepers & best mattress for back sleepers for other mattresses designed to protect the spine and hips in multiple positions.


Both mattresses come with long warranties, but Sleep Number surpasses Tempur-Pedic’s 10-year warranty with a 25-year period. The specialized memory foam used in the Tempur-Pedic construction prevents your mattress from sagging over time, while Sleep Number’s adjustability also allows for an increased level of durability. Tempur-Pedic’s hybrid option is ideal for heavier sleepers due to the incorporated spring coils, which will prevent sagging in the long-term.


Tempur-Pedic’s memory foam mattresses offer exceptional comfort, but it can also cause sleepers to feel wrapped up in the material, making it difficult to stay cool through the night. Sleep Number’s mattress construction, which includes a layer of air chambers, makes it a better option for hot sleepers.

Sizing & Price Comparisons 

Mattress Size  Tempur-Pedic Price  Sleep Number Price 
Twin $1,699 – $2,499 $599 – $2,199
Twin XL $1,699 – $4,199 $699 – $4,399
Full $2,049 – $3,849 $799 – $4,674
Queen $2,199 – $4,699 $999 – $2,899
King $2,899 – $5,399 $1,499 – $3,599
California King $2,899 – $5,399 $1,499 – $3,599

Shipping and Returns 

There are several prominent differences when it comes to shipping and returns between Tempur-Pedic and Sleep Number mattresses. Tempur-Pedic beds have a $25 shipping fee, which includes white-glove delivery. You can also request an old mattress removal, which is included in the shipping fee.

Sleep Number beds come with standard shipping for $89.99, or white-glove delivery for $199. If you choose the white-glove delivery option, your old mattress is taken away at no extra cost. With both mattress companies, customers are responsible for return shipping costs.

Other Models Available

Tempur-Pedic also offers a line of hybrid mattresses with extra support from coils. The biggest difference between memory foam and hybrid mattresses is that the latter is ideal for heavier sleepers who prefer a higher firmness level, more bounce, or just more support overall. 

Sleep Number beds are divided among three variations: Classic, Performance and Innovation. The Classic comes with SleepIQ and Responsive Air technologies, while the Performance goes the extra step and provides additional relief for pressure points. The Innovation series also delivers a temperature-balancing sleep surface to absorb excess heat and keep you cooler throughout the night.


Both Tempur-Pedic and Sleep Number produce high-quality mattresses, but they each have strengths that accommodate different types of sleepers. For those who want better motion isolation, memory foam options and accommodation for almost any type of sleeping position, the Tempur-Pedic is your best bet. If you are a hot sleeper who wants to be able to control and change the mattress’s firmness level, we recommend the Sleep Number bed.
