Ranked #6 in Best Memory Foam Mattresses Queen

Casper

3.7

$1,899as of Jul 9

Casper mattresses are widely available for try-before-you-buy with a 100-night trial and free returns. The Casper One, a base model all-foam mattress, offers a balanced comfort and support feel suitable for back sleepers but may not be ideal for side sleepers or those over 250 lbs. According to Mattress Clarity's Martin, it provides good motion transfer reduction and a medium-firm feel around 7/10, though some side sleepers may experience pressure points. The company's hybrid models offer additional cooling features and spring support, but the basic foam models remain middle-of-the-road in performance. This product fits average-weight back sleepers best, while heavier or side sleepers should consider 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

4.4

$1,299as of Jul 9

The Leesa Original Mattress is described as a balanced memory foam mattress that avoids the typical overheating and sinkiness of other foam beds. Reviewers note its breathable knit cover and responsive GreenFlex foam that keeps sleepers cool while providing quick recovery. The mattress features a 6-inch dense support layer and 2-inch memory foam layer designed to cradle the body and ease pressure points. The 120-night trial period and standard 10-year warranty provide good consumer protection. While praised for its comfort and cooling properties, some reviewers suggest it may not be ideal for very heavy individuals requiring additional support.

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.
