Why We Recommend It
- 01.

- 05.
Polyester cover is removable and washable, making regular allergen removal simple
Considerations
- 01.
Low loft and soft firmness make this a poor match for side sleepers who need more height to bridge the shoulder gap

- 03.
At 24.5x18 inches, the dimensions run on the smaller side despite being listed as a standard/queen option

Fill & Construction
The Leesa Ultra Cool uses a solid gel memory foam fill rather than shredded foam, which gives it a consistent, uniform feel across the entire sleep surface. The gel infusion is integrated throughout the foam core, not just layered on top.
Because this is a solid foam pillow, the loft is not adjustable , Leesa has set it at a fixed low profile designed specifically for stomach and back sleeping positions.
Firmness & Support
Rated soft on the firmness scale, this pillow is built for contouring rather than resistance. The low loft keeps the head close to the mattress, which is exactly what stomach sleepers need to avoid cervical strain from upward neck angles.
Back sleepers get gentle cradling that lets the head sink in without being pushed forward, maintaining a more neutral spine position throughout the night.
Cooling & Breathability
The gel-infused memory foam is the primary cooling technology here, designed to absorb and dissipate heat away from the sleep surface. Only about 57% of pillows on the market include dedicated cooling features, so this puts the Leesa in the upper tier for temperature regulation.
The polyester cover is breathable but not a premium cooling fabric like bamboo or Tencel , most of the thermal management comes from the gel foam itself.
Care & Durability
This is one of the easier memory foam pillows to maintain , the entire pillow is machine washable and dryer safe, which is uncommon for solid foam construction. The removable polyester cover can also be washed separately for quick refreshes between full washes.
Regular washing extends the pillow's lifespan and keeps allergens in check, making this a practical choice for allergy-conscious sleepers.
Who Is This Pillow For?
Ideal For
- ✓ Stomach sleepers who need a low-profile pillow that won't force the neck into an awkward upward angle
- ✓ Back sleepers who prefer a soft, contouring foam pillow that cradles without excessive lift
- ✓ Hot sleepers looking for gel-infused cooling technology to reduce overnight heat buildup
- ✓ Anyone who wants a fully washable memory foam pillow , toss the whole thing in the machine, not just the cover
Not Ideal For
- ✕ Side sleepers who need medium to high loft for proper spinal alignment , this pillow sits too low
- ✕ Sleepers who prefer adjustable loft pillows where you can add or remove fill to dial in the height
- ✕ Those who like a firm, supportive pillow , this is intentionally soft with deep contouring
Like most compressed memory foam pillows, the Leesa arrives vacuum-sealed and will need time to expand to its full low-loft shape. Allow 24-48 hours for the foam to fully decompress and for any initial off-gassing to dissipate.
Toss it in the dryer on low heat for 10-15 minutes after unboxing to speed up the expansion process
Give it a full day before judging the loft , compressed foam pillows need time to reach their intended profile
Leesa includes a 30-night trial period so you can sleep on the pillow before committing. For specific warranty duration and coverage details, verify directly with Leesa as terms may vary by purchase channel.
FAQ
Can I wash the entire Leesa memory foam pillow or just the cover?
You can wash the entire pillow , it's fully machine washable and dryer safe. This is relatively uncommon for solid memory foam pillows.
The polyester cover is also removable for separate washing between full pillow washes.
Is this pillow good for side sleepers?
This pillow is not ideal for side sleepers. The low loft and soft firmness don't provide enough height to fill the gap between your shoulder and head, which can lead to neck misalignment.
Side sleepers should look for a medium to high loft pillow with firmer support.
How does the gel cooling technology actually work in this pillow?
The cooling technology uses gel infused directly into the memory foam core. The gel particles absorb body heat and distribute it away from the sleep surface, helping regulate temperature throughout the night.
It's integrated throughout the foam rather than applied as a surface layer.
What size bed does this pillow fit?
At 24.5x18 inches, this pillow fits standard and queen size beds. Two pillows will sit side by side on a queen mattress.
Note that the dimensions run slightly compact compared to some queen-labeled pillows on the market.
Does the Leesa pillow lose its shape over time?
Solid gel memory foam construction generally holds its shape better than shredded foam or fiber-fill alternatives. The foam returns to its original low-loft profile after each use.
Machine washing per care instructions helps maintain the foam's integrity and extend the pillow's usable lifespan.
How firm is this pillow compared to a traditional memory foam pillow?
This is a soft-rated pillow with a low loft, so it sits noticeably flatter and softer than most standard memory foam pillows. It's designed for contouring and cradling rather than firm support.
If you prefer a pillow that pushes back against your head, this one will feel too soft.
