Higher ratedRanked #3 in Best Pillows for Side Sleepers
Layla Kapok Pillow
$114as of Jun 7

The Layla Kapok Pillow is the best-value side-sleeper pick, scoring 9.3/10 from Sleep Foundation. Its blend of kapok tree fiber and shredded memory foam is fully adjustable, you unzip and remove fill to set your ideal loft, which is exactly what side sleepers need to align the neck. A copper-infused cover and breathable fill keep it cool, and a 4.5/5 average across 3,300-plus reviews backs it up. For adjustability and cooling per dollar, it is hard to beat.

Strengths
  • Sleep Foundation's Best Value side-sleeper pillow at 9.3/10, praised for cradling and supporting the neck and shoulders
  • Fully adjustable fill, unzip and remove kapok-and-foam blend to set the exact loft side sleepers need
  • Copper-infused cover plus open-cell foam and airy kapok fiber make it one of the better cooling memory-foam pillows
Watch-outs
  • At just over $100 it is pricey for a foam-fill pillow
  • Shredded fill can need fluffing and occasional redistribution to stay even
  • Removing fill to adjust is a slightly messy, one-time hassle
Purelux Simply Cool Memory Foam Pillow
Ranked #5 in Best Pillows for Side Sleepers
Purelux Simply Cool Memory Foam Pillow
$50

The Purelux Simply Cool is the budget cooling pick, around $50 yet genuinely focused on temperature. Its PureGel memory foam pulls heat away and the ActiveChill cover stays cool wash after wash, while tailored raised sides give the lift side sleepers need for neck support. It is solid molded foam, so it is not adjustable and is less plush than premium rivals, but for an affordable, cool, supportive side-sleeper pillow it punches well above its price.

Strengths
  • Genuinely cooling: PureGel memory foam transfers heat away while the ActiveChill cover stays cool and never washes out
  • Tailored, raised sides give extra lift to cradle the head and neck for side-sleeper spinal support
  • Lab-reviewed by Consumer Reports and recommended as a strong cooling option for side sleepers
Watch-outs
  • Solid one-piece foam is not adjustable, so loft and firmness are fixed
  • Lower-profile and less plush than the high-loft Saatva Cloud or firm Tempur ProHi
  • Lacks the premium materials and brand backing of the pricier picks

How they stack up

Layla Kapok Pillow

Like the Eli & Elm Side Sleeper Pillow it offers adjustable fill, but in a traditional shape closer to the Saatva Cloud Memory Foam Pillow. It is more adjustable than the fixed-loft Saatva Cloud Memory Foam Pillow and Tempur-Cloud ProHi Pillow, and cools better than most memory-foam rivals thanks to its copper-infused cover.

Purelux Simply Cool Memory Foam Pillow

The most affordable and most cooling-focused pillow here. It is less plush than the Saatva Cloud Memory Foam Pillow and Layla Kapok Pillow and not adjustable like the Layla Kapok Pillow or Eli & Elm Side Sleeper Pillow, but it delivers active cooling the neutral Saatva Cloud Memory Foam Pillow does not.
