Ranked #6 in Best Memory Foam Mattresses Queen

4 sources$1,899as of Aug 1

Casper mattresses are easy to try before buying, with a 100-night trial and free returns. The Casper One, the base all-foam model, aims for balanced comfort and support, which works for back sleepers but less so for side sleepers or anyone over 250 lbs. Mattress Clarity's Martin reported good motion transfer reduction and a medium-firm feel around 7/10, with some side sleepers hitting pressure points. The hybrid models add cooling features and spring support; the basic foam models stay middle-of-the-road. Average-weight back sleepers are the right buyer, and heavier or side sleepers should look at alternatives.

Strengths
  • Easy to try and buy with quick shipping and store availability
  • 100-night trial and free returns
  • Minimalist design with smooth gray sock-style cover
Watch-outs
  • Not ideal for side sleepers due to pressure points
  • May lack sufficient support for heavier individuals (over 250 lbs)
  • No specific foam density information provided by manufacturer

Leesa Original Mattress
6 sources$725as of Aug 1

Reviewers describe the Leesa Original Mattress as a balanced memory foam bed that sidesteps the overheating and sinkiness common to foam. They point to a breathable knit cover and responsive GreenFlex foam that keeps sleepers cool and springs back fast. Inside, a 6-inch dense support layer sits under a 2-inch memory foam layer meant to cradle the body and ease pressure points. A 120-night trial and standard 10-year warranty back the purchase. Comfort and cooling get the praise, though some reviewers suggest very heavy sleepers will want more support than it provides.

Strengths
  • Breathable knit cover with moisture-wicking fibers helps prevent overheating
  • Responsive GreenFlex foam provides cool sleeping experience and quick recovery
  • Cradling memory foam layer contours to body and relieves pressure points
Watch-outs
  • Limited lifetime warranty may not cover all potential issues
  • May not suit very heavy individuals who need extra support

How they stack up

Casper

The Casper mattress offers a balanced comfort and support feel suitable for back sleepers, but it's not ideal for side sleepers or heavier individuals compared to the Saatva Loom & Leaf, which provides a softer, more conforming surface.

Leesa Original Mattress

The Leesa Original Mattress stands out with its breathable knit cover and responsive GreenFlex foam that keeps sleepers cool, which the Nectar Premier lacks in terms of cooling properties. While it offers good pressure relief, it doesn't provide the same level of support as the Saatva mattresses, which feature dense memory foam and sturdy coils.
