There are a lot of mattress options to choose from today from hundreds of leading brands like Sealy, Simmons, Saatva, Nectar, Layla, Loom and Leaf, Brentwood Home, Leesa, and more.

Almost everyone sells online now which makes saving money and time a lot easier.

King Size Mattress

With so many choices, though, it can be difficult for you to make a decision on which mattress is truly the best for your needs.

Based on our experience at reviewing more than 60 of the best mattresses sold online, here’s what we think are some of the best king-size mattresses sold today – for a few common needs:

Best King Size Mattress

Nectar:  Best Value

Although still a startup, Nectar (sold online only) has quickly emerged as one of the best foam mattresses, and it’s our top value pick because of its exceptional value and lifetime guarantee.

The Nectar mattress comes in just one comfort level: a medium-firm that offers solid support in lower layers with an incredibly soft and luxurious top comfort layer that uses premium foams.

The Nectar quickly became one of our top-rated mattresses after we reviewed it and it is extremely popular today. We love this one.

DreamCloud: Affordable Luxury

DreamCloud, also sold exclusively online, makes our list because of its unique combination of a world-class tufted pillow-top sleeping experience and its really low price.

Not only do the materials used in this mattress offer a substantial value, but it comes with a 1-year risk-free in-home trial, to boot.

This hybrid mattress is constructed to create an impression, and it certainly does with a 15-inch thickness, 8 layers of top-quality foams and coils, and a gorgeous hand-sewn tufted pillow top that looks like it belongs in a Ritz Carlton suite.

If you are confused between Dreamcloud and Nectar, check this comparison for clarity.

Loom & Leaf:  Luxury Foam Defined

The Loom and Leaf mattress (made by the US manufacturer Saatva, from all-American components) has remained one of our highest-rated mattresses since 2015 and remains that way for a lot of reasons.

This 12″ thick all-foam mattress consists of 5 layers of top-quality foams and medical-grade cooling gel in the comfort layer. Most foam mattresses in its price category use 2 or 3 layers, for comparison.

The L&L mattress comes in two comfort choices, those are Relaxed Firm and Firm. Both offer superb comfort and fantastic support for your body and spine.

Layla Sleep: Best Choice for Hot Sleepers

Layla is a new top pick for now.  Layla sells one of the most advanced memory foam mattresses today. This mattress incorporates copper-infused foam and a ThermaGel cover which provide outstanding cooling properties.

The beauty of their design is that the cooling effect only activates if it senses moisture or heat, therefore it won’t also cool you in winter days.

Copper is also purported to help ease inflammatory diseases like rheumatoid arthritis and osteoarthritis, and may also boost blood circulation.

Novosbed: Built to Last

The Novosbed all-foam mattress is an 11″ bed composed of 5 layers of foam. It is offered in 3 comfort options – the one we reviewed is the Medium firm and we love it.

Novosbed is not the cheapest foam mattress you can buy online, but it’s definitely one of the best and is built to last, with an extra-long 15-year warranty.

The cover of the Novosbed mattress is made of silica, polyester, Tencel, and modacrylic. It has a lovely soft textured pattern that gives this mattress an incredibly smooth feel against your body.

For additional comfort and a plush feel opt for high-quality super king bedding because beddings come directly in contact with the body and are responsible for the comfort you are likely to receive from your mattresses mainly.

Helix Mattress: Custom-Fit Luxury

Helix has what we think is the most exciting approach when it comes to selling mattresses online.

Helix sells what is technically a hybrid mattress made of poly foam and coils that can be customized to fit your unique needs and sleeping style.

The difference is: you can completely customize the firmness, feel, cooling, and split comfort level of your Helix mattress by filling out a brief questionnaire on their website. The mattress you receive is built to meet your body weight, sleeping style, and comfort preferences.

Or, you can choose from one of over a dozen pre-configured mattresses to meet your whims.

Springs add an excellent cooling effect, and the foam provides extra pressure relief and contouring.

We’ve tested two so far and both are outstanding.

Avocado Green Mattress:  Best Organic Hybrid

The Avocado mattress is a brand-new luxury latex and coil hybrid mattress which uses green and eco-friendly materials in its structure.

The Avocado Green mattress is handmade in the USA without petroleum-based polyurethane foam, without toxic flame retardants, without harmful pesticides, and without danger from volatile chemicals and gasses.

If you care about keeping questionable chemicals out of your home and helping the environment, you should definitely check out Avocado Green.  Sold online only.

Saatva: Best Innerspring Mattress

Saatva’s excellent foam-top innerspring mattress remains one of the highest-rated mattresses on our site.

While every new mattress startup seems to be obsessed with making 100% foam mattresses, Saatva has kept to its origins and remains focused on making the most comfortable innerspring mattress sold directly to consumers.

Now, it is quite true that memory foam provides excellent support and contouring. That’s why Saatva incorporates foam into their pillow-top innerspring hybrid. But just a little.

Saatva’s coil-on-coil spring core layer offers superior cooling and strong support while their Euro-style pillow top and memory foam provide outstanding comfort.

If you’re in the market for a luxury innerspring mattress, then definitely give them a look.


So that’s a taste of the kind of quality you can find by buying your next king-sized mattress online.

The online bedding industry continues to explode, with new options and products coming out every month.
