Sleep can make or break your day. If you wake up feeling energized and refreshed, concentrating and functioning will be a breeze. On the other hand, if you spend most of your nights tossing and turning, the whole day can feel like a challenge. You’ll be fatigued, irritable, and reaching for the nearest caffeine source. 

According to the , sleep deprivation might lead to serious health problems, including diabetes, high blood pressure, heart disease, and obesity. So it’s something to take seriously. If you need to improve your quality of sleep, it might be time for you to buy a new mattress. 

Buying a mattress is now easier than ever, especially with so many online companies selling state-of-the-art mattresses and delivering them straight to your door. Some even come with all the bells and whistles, like memory foam, cooling layers, and anti-wicking fabric, to help you rest easy and keep pain at bay. 

Now, you can’t just settle on any online mattress. It has to meet your needs, whether you need to decrease joint stiffness or stay sweat-free at night. It shouldn’t require much time to put together, or else you’ll most likely not use it. With all the options out there, it can be challenging to find the right model. Before you drop major bucks on an online mattress, there are some things you might want to consider. 

Bed size: Don’t play Goldilocks when you’re shopping for an online mattress. Take measurements of your bed first, so you’re prepared to compare models. If a mattress has equivalent dimensions, you’ll know it’s the right fit. If not, skip it, and see your other options. It’s important that a mattress is available in many bed sizes. You don’t want to waste time returning or exchanging an online mattress. 

Sleep style: Do you sleep on your back, on your side, or stomach? Knowing your sleeping style is key for buying an online mattress. Some mattresses are extra firm, while others are made with softer materials. You want to be super comfortable while you catch up on some ZZZs. 

Health concerns: Speak with your doctor first before choosing an online mattress. If you’re prone to joint pain, you’ll want to opt for a mattress that offers good body support. For overheating issues, choose a mattress with cooling technology. Concerned about your environmental impact? Some mattresses are even made with eco-friendly materials, so you can rest easy and minimize your carbon footprint. 

Warranty: Online mattresses don’t always come cheap, so you’ll want to consider a company’s warranty before making a commitment. Look for warranties that offer flexible coverage and support, so you won’t have to spend an arm and a leg for repairs and replacements. 

Whether you are all about memory foam or temperature regulation, there’s an online mattress out there for your sleeping needs. Here are our top seven picks for the best online mattresses.

, a Casper customer, writes: 

“This was my first bed-in-a-box adventure, and I must say I was surprised. I’m in my mid-50s and accordingly have some typical aches and pains. So I’ve been pretty conscious about what I sleep on, because there’s almost nothing worse than a sleepless night to make me worthless at work the next day. I had a hard time believing that the Essential would be ‘enough’ for me, but it was — enough buoyancy, enough support, and enough fluffy comfort.”

“I received your mattress almost two weeks ago. I had been “nervous” about ordering a mattress from an online store, but I did a lot of research before finally choosing a Saatva mattress. I could not believe how comfortable the bed was! For the first time in years, I could sleep on my stomach and sides without pain, numbness, and tingling! I forgot to mention that I am loaded with arthritis and within the last nine years have had to have two back surgeries, two knee replacements, and a right hip replacement.

It’s been about six weeks now and I truly couldn’t be more pleased with my Leesa.”

., an Avocado reviewer, writes:

“So far I LOVE my Avocado. For years I have been frustrated by the “tricks” of the mattress industry and the hidden chemicals in many mattresses. I have only had my Avocado for a week, but so far, so great. I am a mid-sized, middle-age woman and did not order the extra layer of latex. My mattress sleeps cool and I do appreciate the inner springs. The foam mattress I tried just did not cut it. Also, customer service has been amazing.”
