Nectar Premier

Best king size memory foam mattress

Our take - It's the best king-size bed for people who want the traditional memory foam feel you can find in a Tempur-Pedic mattress at a more wallet-friendly price. It has a thick memory foam construction, giving it a relieving and slow-responding memory foam feel. It takes a few seconds for your body to activate the foam, but once it does, the memory foam slowly contours around your curves and nestles you into the bed.

DreamCloud Premier Hybrid

Best king size bed in a box mattress

Our take - The DreamCloud Premier Hybrid is the best king-sized bed in a box mattress. It’s a premium, 13-inch-thick bed that combines layers of gel memory foam and durable coils. The hybrid construction gives the DreamCloud Premier mattress a nice mix of pressure relief and durability, with reinforced edges and reduced motion transfer.

Allswell mattress

Best affordable king mattress

Our take - You may not be familiar with Allswell, but you're likely familiar with its parent company Walmart. As its entrance to the bed-in-a-box game, Walmart introduced the affordable Allswell mattress. The Allswell mattress is a good hybrid mattress for the price of a low-budget foam mattress, giving it a well-deserved spot on this best king bed list.

Saatva Rx

Best king size mattress for back pain

Our take - If you live with back pain, you need a king-sized mattress that relieves it, not adds to it. The Saatva Rx mattress was designed to alleviate back pain from chronic conditions like scoliosis or sciatica.

Layla Hybrid

Best king size mattress for side sleepers

Our take - In a sea of bed-in-a-box mattresses, brands have to add a little sauce to their designs to make them stand out. The Layla Hybrid is unlike most other hybrid mattresses because it comes with a two-in-one deal. What I mean is that it's flippable, and you can sleep on each side of the mattress comfortably.

Other mattresses we've tested

Brooklyn Bedding Aurora Luxe: Many mattresses make embellished claims about their cooling abilities, but the Brooklyn Bedding Aurora Luxe effectively works to cool. With multiple cooling enforcements including cooling foam, Titan Cool technology and a cooling cover. With three firmness levels to choose from and a strong hybrid construction, it's a versatile mattress that works for any sleeping position and body type.

Purple mattress: There aren't many mattresses out there like the Purple. It's made with a special gel-like material the brand calls its GelFlex Grid. It's squishy and firm at the same time, offering a nice balance of support and pressure relief. It has a medium firmness level that suits all sleeping positions.
