The Helix Midnight is a hybrid mattress with foam and coils providing pressure relief and support. The mattress fits side and lightweight back sleepers, but heavier individuals and stomach sleepers may prefer a firmer bed.

The coil unit features individually-wrapped coils to minimize motion transfer, so the Helix is good for couples with different sleeping preferences. The bed has thicker-gauge coils in the perimeter for added edge support, allowing you to use the entire surface of the bed.

If you struggle with back pain, it’s possible that your king-size mattress isn’t providing enough targeted support. The Saatva Classic aims to provide just that, with multiple features that encourage healthy spinal alignment.

This luxury innerspring model includes Lumbar Zone® Technology that ups the support in the mattress’s middle—directly under the portion of the spine that most needs a sturdy foundation. It also has a dual-coil design that combines a base coil unit with a separate system of pocketed springs. Together, these coils lend the bed helpful responsiveness and even more support, a beneficial combo for achy backs.

Why do we love it?

• Topping off Saatva is an euro pillow top crafted from organic cotton. Beneath this is a layer of memory foam that helps with pressure relief and increasing the overall comfort of the bed.
• Saatva offers free white glove delivery, meaning there is no unboxing period or heavy lifting. You can throw sheets and pillows on it right away and enjoy a luxurious night of sleep right away.

Five different layers of foams and individually wrapped coils help this bed reach its 14-inch profile. This model was made to help sleepers obtain maximum shuteye by targeting their comfort and support needs. This bed’s price tag is cheaper than many other luxury brands but does not sacrifice quality. 

The DreamCloud Premier has a medium firmness that should work well for couples, and the brand uses individually wrapped coils to help minimize motion transfer for a more peaceful rest.

What makes it special?

• DreamCloud Premier is furnished with a Cashmere-blend cover that’s quilted to 2 inches of foam, including 1 inch of gel-infused memory foam. This should provide excellent pressure relief for those struggling with aches and pains.
• Reinforced edges allow couples to take advantage of the full surface area and should be helpful for those needing support getting out of bed.

The Emma Original king-size mattress is especially affordable when compared to competitors—the brand commonly offers it at sales prices of less than $1,000. That’s a desirable deal when you consider the thought that went into its multiple foam layers and reinforced edges.

Although some foam mattresses can be inefficient at cooling, the Emma fights off heat with a moisture-wicking, breathable cover and a layer of AIRGOCELL® foam, which vents away excess body heat. The HALO® Memory Foam beneath it contours to key pressure points and helps to encourage proper spinal alignment.

What else should you know?

• The durable foam base that acts as this bed’s foundation is impressively resilient and engineered to resist sagging over time.
• This king-size mattress is also a great bet for couples, as its foam layers restrict motion transfer for uninterrupted rest on both sides.
