leesa hybrid mattress review edge support

Why Leesa Hybrid wins as best overall

As the coil version of the Leesa mattress, the Leesa Hybrid is more supportive. In fact, for individuals weighing over 250 pounds, we definitely recommend this model over the flagship one. It still has a neutral, comfy feel, but it mixes in pocketed coils for added durability.

Leesa Hybrid’s best features

  • Suitable for a variety of body types and sleeping positions
  • Good motion isolation and edge support means that it’s a good pick for couples
  • Responds quickly to pressure without creating that “stuck-in-the-mud” feeling

Why we picked this bed

While there are cheaper mattresses out there, the Lucid Hybrid made the list because it’s a safe pick. This is especially true if you’re a heavy sleeper looking for more support or if you sleep on your back or stomach at night.

Why Sweetnight Twilight wins as best support

When you sleep primarily on your back or stomach, you’ll probably want to look for a slightly firmer bed that can offer ample support under your body — and the 12” Sweetnight Twilight does exactly that. It has a medium-firm rating on our firmness scale, accompanied by a neutral-soft feeling that most people should enjoy.

Sweetnight Twilight’s best features

  • Five-layer construction includes individually wrapped pocketed coils, making it better for heavier folks and hot sleepers
  • CertiPUR-US certified foam is made without toxins or harmful chemicals
  • Affordable price tag makes it an excellent pick for budget-conscious shoppers

Why we picked this bed

Since the Sweetnight Twilight is on the firmer end of the spectrum, it’s a good option for back and stomach sleepers — especially if you’re on a budget. The hybrid construction also makes it a compelling option for larger individuals.

tuft and needle mint mattress review stomach sleeper

Why Tuft & Needle Mint wins as best pressure relief

As the premium mattress offering from Tuft & Needle, the T&N Mint is an all-foam bed that feels like you’re sleeping on a cloud. At night, side sleepers require pressure relief underneath their shoulders and hips, which this mattress delivers. In terms of firmness, the Mint is on the softer side (we rated it between a medium-soft and a medium), with an incredibly comfortable and responsive feel.

Tuft & Needle Mint’s best features

  • Neutral, soft-foam feel that a majority of people can appreciate
  • Pressure-relieving qualities make it an excellent choice for people with pain in their shoulders, hips, or joints
  • Better durability than many other all-foam beds since it’s 2” thicker than most similar products

Why we picked this bed

Not only is the Tuft & Needle Mint our best king-size mattress for side sleepers, but it’s also one of our all-around best mattresses for side sleepers. We also think that most combination sleepers will like it. All in all, the Mint is soft, comfy, affordable, and worth considering.

casper element review back sleeper
We think Casper Element suits all sleeper positions, including back sleepers.

Why Casper Element wins as best all-foam

The 10” Casper Element is a simple yet comfortable all-foam bed that’s a bit firmer than the Original Casper mattress. It has a basic two-layer construction that includes a dense foam support core topped by a comfort layer of AirScape foam, which is perforated for additional airflow. Altogether, it has a neutral-foam feeling that many people prefer over memory foam.

Casper Element’s best features

  • Nice choice for couples because of its strong edge support and motion isolation
  • Suitable for various sleeper styles, including back, stomach, side, and combination
  • Budget-tier bed from a reputable online mattress company

Why we picked this bed

Even though it’s only made with two layers, the Casper Element is easy to enjoy. Plus, it’s accommodating for all sleeping positions and has that neutral-foam feeling that most people won’t complain about.

lucid gel memory foam hybrid mattress review

Why Lucid Hybrid wins as best value

Shopping for a king mattress can get expensive quickly, so we thought it was important to include a few budget-friendly options on this list, including the Lucid Hybrid. It’s a 12” innerspring and foam bed that works for petite, average, and heavy body types, as well as all sleeping positions.

Lucid Hybrid’s best features

  • Hybrid construction provides the long-term support that larger folks need in a mattress
  • Medium firmness profile that feels like neutral foam with a hint of memory foam
  • One of the cheapest king-size mattresses available online

Why we picked this bed

If you’re concerned about cost, you can’t do much better than the Lucid Hybrid. Not only does it have a low price point, but it’s also soft and comfortable, with several layers of foam and a strong inner support system of pocketed coils.
