Side-By-Side Comparison

Both Casper and Sleep Number offer affordable, durable mattresses with brand-unique cooling and comfort technologies. Both brands offer attractive shipping policies and provide an 100-day sleep trial to make sure you're satisfied with your new mattress. So which should you choose?

Casper is a great choice if you're a particularly hot sleeper because of its brand-unique Airscape foam technology. All Casper mattresses feature this one-of-a-kind cooling technology specifically designed to keep you at the optimal sleep temperature all night, and the Wave Hybrid includes cooling gel for extra temperature control. Additionally, Casper is a great choice if you're looking for customized sleep support at varied price points, with Casper's most luxurious and advanced models thousands less than Sleep Number's.

On the other hand, Sleep Number mattresses target specific sleep needs using smart technology synced to their handy remote. Sleep Number is great for couples because all of its models allow you and your partner to select your own firmness for better sleep together. We recommend Sleep Number if you prefer a mattress that can adapt to your needs, and with a 15 year warranty, this brand's slight price inflation pays off in the long run.

How To Choose The Right Mattress

First off, if your current mattress is 7-10 years old and you're experiencing more body aches and pains, it's time to buy a new mattress. Getting a good night's sleep is essential in maintaining a healthy body and mind. Choosing the right mattress doesn't have to be a hassle, follow these guidelines to find the right one for you!

  • Choose a mattress based on your individual needs. If you're looking for plushier support that adapts to your body's shape, a memory foam mattress is the best choice. If you want a more firm, traditional, feel an innerspring mattress is what you want. For the best of both worlds, get a hybrid mattress.
  • Get proper lumbar support. The majority of your body weight is positioned in what is called the "center third" of the mattress. Find a mattress that has excellent lumbar support as it prevents and alleviates pain in the back and hips. If you're looking for extra support, Saatva's unique lumbar zone technology might be the best fit.
  • Find a mattress with a long in-home trial. You want to be able to test your mattress over an extended period of time to really make sure this is the right one for you. Look for a company that offers a risk-free in-home sleep trial. Nectar offers a 365-day trial. IDLE Sleep offers a full 18-month trial (the longest in the industry).
