10 Best Pillows for Side Sleepers of 2026

Coop's Original Adjustable Pillow ranks first because it solves the main problem side sleepers with neck pain have: finding the right height. The pillow comes overfilled with a blend of cross-cut memory foam and microfiber, and you remove or add fill through a zipper until your neck sits level with your spine. Coop includes extra fill in the box, so you can go higher as well as lower. Besides the rectangular Classic, Coop sells a Crescent shape and a Cut-Out shape, which leaves room for the shoulder. Both the pillow and its Lulltra cover are machine washable, and the foam is GREENGUARD Gold and CertiPUR-US certified. The 100-night Sleep Better Guarantee and 5-year warranty are among the most generous terms on this list. The queen Classic was $88.77 when we checked. The main caution is patience: plan on a few nights of adjusting before it feels right.

Eli & Elm's Side Sleeper Pillow is the most specialized design on this list. Its U-shaped curve lets the lower shoulder sit in the contour of the pillow while the head and neck stay level, which Eli & Elm says reduces strain on the cervical spine. You choose the fill when you order: a latex option made of 75% cooling Dunlop latex noodle and 25% polyester fiber, or a softer option with 75% shredded memory foam. A zippered liner lets you add or remove fill up to a maximum loft of 6 inches, and extra fill is sold as an add-on. The queen measures 18 by 28 inches. The cover is machine washable, but the fill must not go in the washer or dryer. The queen was $114.99 on sale when we checked, against $135.99 original, which puts it near the top of this list on price. A 45-day return policy is shorter than Coop's.

Layla built the BioCrystal Side Sleeper Pillow around a sculpted U-shaped cutout and a tall profile. It arrives at a 7 inch loft, which Layla calls ideal for most side sleepers, and you unzip the cover to remove one foam layer for about 6 inches or two for about 5 inches. That makes it a good match for people with broad shoulders or a firm mattress, who need more height than the 6 inch maximum on the Eli & Elm. Because it uses layered foam rather than shredded fill, the surface stays smooth and the height changes in clear steps. Layla infuses the foam with a blend of 16 milled crystals it calls BioCrystal and says the surface stays cool. The pillow is OEKO-TEX Standard 100 certified as a complete product. It cost $149 when we checked, against $189 regular. The 30-night trial is short, and Layla asks buyers to sleep on it for at least two weeks before returning it.

Avocado's Green Pillow is the natural-materials pick, and the version that matters here is the Side-Sleeper shape. Avocado describes it as ergonomically curved to cradle the head and fill the space between ear and shoulder, keeping the neck in neutral alignment. Both shapes use the same fill: ribbons of GOLS certified organic latex mixed with GOTS certified organic kapok fiber inside an organic cotton cover, with no polyurethane foam or polyester. The pillow arrives overfilled and medium-firm, so most side sleepers will remove a handful of fill at a time until the height is right, and an extra fill bag is included if you need more. Avocado lists Greenguard Gold, OEKO-TEX Standard 100 and MADE SAFE certifications, a 100-night trial and a Good Housekeeping two-year limited warranty. The feel is springy and heavier than a typical pillow. Our checker could not read a USD price on the page, so see the store for the current price.

Tuft & Needle's Zip Comfort Pillow is the budget pick, and it still lets you adjust. Instead of removing fill by hand, you open or close two zippers along the side to choose a soft, medium or firm feel, which is a simpler routine than the loose-fill pillows above it. The fill is a blend of 60% shredded foam and 40% fiber inside a 100% cotton sateen cover quilted in a chevron pattern to help the pillow keep its shape. Tuft & Needle sells it with a 100-night sleep trial, free shipping and returns, and a 2-year limited warranty. The queen was $56 when we checked, against $70 regular, the lowest verified price on this list. The trade-offs are a plain rectangular shape with no shoulder cutout, a shorter warranty than most picks, and spot-clean-only care. For a side sleeper with mild neck pain, the firm setting is the place to start.

Casper's Original Pillow is the soft, easy-care choice. It uses a pillow-in-pillow design: a supportive inner pillow sits inside a softer outer pillow, both filled with recycled down-alternative fibers, under a 100% cotton percale cover. Casper says its medium profile suits side sleepers and that stomach sleepers can take the inner pillow out for a low loft. The whole pillow is machine washable, which none of the foam and latex picks above it fully allow. The standard was $67.50 when we checked, against $75 regular. For side sleepers who wake with real neck or shoulder pain, the limits are clear: fiber fill gives less firm support under a heavy head than foam or latex, you can only make it lower rather than higher, and there is no shoulder cutout. Casper accepts returns within 30 days if the item meets its conditions and backs the pillow with a 1-year limited warranty.

Purple's Harmony Pillow takes a different route from the adjustable pillows above it: instead of letting you change the fill, Purple sells it in three fixed heights. The low version is 5.5 inches, the medium 6.5 inches and the tall 7.5 inches, and Purple recommends medium or tall for side and combination sleepers, with tall for large frames. Inside is a ventilated Talalay latex core wrapped in Purple's honeycomb GelFlex Grid, which Purple says draws heat away and adds pressure relief, under a moisture-wicking stretch knit cover that is machine washable. Purple describes the feel as medium firm, airy and bouncy, and says it does not fall flat. The weakness for anyone still working out their ideal height is that you cannot change it later, and the 30-night trial and 1-year warranty are short.

The TEMPUR-Cloud Adjustable Pillow puts Tempur-Pedic's pressure-relieving material into a pillow you can shape yourself. The TEMPUR-Blend fill sits in a stretchy liner, and a zipper lets you fluff, scrunch, flatten or remove some of it to change height and support. Tempur-Pedic lists it for side, back and stomach sleepers. The cover is removable and machine washable and is treated with Surface Guard Technology against common allergens, and a cooling version costs $10 more. The queen was $74 when we checked, which is low for this brand, and it carries a 5-year limited warranty. Two points hold it back for side sleepers in pain. The listed queen height is about 5.25 inches, which can be short for broad shoulders, and Tempur-Pedic's return policy says pillows may not be returned. That means you cannot send it back if it does not fix your neck, so it suits buyers who already know they like Tempur material.

Brooklinen's Marlow Pillow pairs adjustable firmness with cooling-infused memory foam. Two zippers change its profile, giving three loft options without opening the pillow or handling loose fill, which Brooklinen sums up as unzip to find the right feel. The fill is 80% memory foam and 20% polyester fiber inside a 100% cotton sateen shell with polyester mesh gussets that help air move through. Brooklinen calls it vegan and allergy friendly and sells it in standard and king sizes. For side sleepers, the memory foam blend gives more support than a fiber pillow, and the zippers make it easy to try a higher or lower setting. What holds it back is a plain rectangular shape with no shoulder cutout and few published numbers: Brooklinen does not list the loft heights of each setting, so it is harder to match to your shoulder width than Purple or Layla. Our checker could not read a USD price on the page, so see the store.

Sleep Number's ComfortFit Pillow blends memory foam pieces with down-alternative fibers under a breathable Lyocell blend cover, and it comes in three shapes. The Curved shape is the one for this list: Sleep Number says it fits your contours and marks it best for side or back sleepers. The Ultimate shape takes a different approach, with three removable inserts so you can change height, and Sleep Number recommends two or three inserts for side sleepers. The foams are CertiPUR-US certified, the pillow is hypoallergenic, and it is made in the USA of imported materials. The standard was $99.99 when we checked, with a buy one, get one 50% off offer. It ranks last because that price buys less adjustment than cheaper picks: the Curved shape has fixed fill, the Curved and Classic shapes are spot clean only, and the product page does not state a trial length. It makes most sense for people already shopping Sleep Number.
