Eli & Elm Side Sleeper Pillow: Latex vs Memory Foam and Rivals

The Eli & Elm side sleeper pillow is a U-shaped, 6 inch tall, adjustable pillow that comes in a latex fill and a memory foam fill, and for most side sleepers the cooling latex version is the better choice because it stays springy and breathes better, while the memory foam version suits people who want a slower, hugging feel. If you are shopping for a side sleeper pillow with a cutout and want alternatives, the Coop Home Goods Cut-Out Adjustable Pillow is the closest rival and the Avocado Organic Side-Sleeper Pillow is the premium natural option.

This guide is written for people who typed “eli and elm side sleeper pillow reviews” and want a clear comparison rather than a sales page. It covers what the pillow is made of, how the two fills differ, who should pick which, and which competing pillows are worth cross-shopping. It is based on published specifications and independent coverage, and it makes no claim that any pillow treats neck pain; if you have ongoing pain or numbness, a doctor or physical therapist should guide the choice.

Comparison Table

What the Eli & Elm Side Sleeper Pillow Actually Is

Before comparing, it helps to be clear about the design, because the brand sells more than one pillow and the listings use similar names. The side sleeper model is a U-shaped pillow: a scooped cutout on one long edge lets your shoulder tuck in so the head can sit lower than the edges. Both fills are listed at 6 inches high, which Bed Bath and Beyond describes as mid loft. The queen is listed at about 18 by 28 inches on the maker side, though some retailer titles round it to 17 by 29, and the king is about 18 by 32 inches. A zipper on an interior liner allows you to add or remove fill, so the 6 inch height is a starting point rather than a fixed number.

The fill options are the key choice. The latex version uses cooling Dunlop latex noodles, about 75 percent of the fill, mixed with about 25 percent polyester fiber. The memory foam version uses about 75 percent shredded memory foam with the same polyester share. The outer cover is a blend listed at about 37 percent cotton, 2 percent spandex and 61 percent polyester with a 300 thread count, and it can be removed and machine washed in cool water, while the fill should never go in a washer or dryer. Independent coverage lists a medium-firm feel and a five-year warranty. If you search for the “eli & elm cotton side sleeper pillow,” this cotton-blend cover is what that wording refers to; the pillow is not all cotton.

1. Eli & Elm Side Sleeper Pillow, Cooling Latex: Best Overall

• U-shaped contoured design with a shoulder cutout
• About 75% cooling Dunlop latex noodle and 25% polyester fiber
• 6 inch height; interior zipper for adding or removing fill
• Queen about 18 x 28 x 6 in; king about 18 x 32 x 6 in
• Removable cover with cotton, spandex and polyester blend

Best for: side sleepers who want support that pushes back and a pillow that runs cooler. Skip if: you have a latex allergy or you like a slow, sinking feel.

Latex noodles behave differently from foam. They are small pieces of natural-feeling, open-cell rubber, so they shift when you press and spring back when you lift your head, which makes turning over easy. The gaps between noodles let air move, which is the basis for the cooling claim. For side sleepers, the combination of a cutout and noodles means the neck is held level without the head being wrapped in warm foam.

The adjustability is an underrated benefit. Pulling out a handful of noodles lowers the loft, which helps narrow-shouldered sleepers, while leaving the full fill suits broad shoulders. Expect some rustling noise when you move, as with any pillow filled with noodles, and a short adjustment period of a week or so.

Pros: springy support; cooler fill; adjustable; U-shape fits the shoulder; machine-washable cover. Cons: premium price; some noise; not suitable for latex allergies.

2. Eli & Elm Side Sleeper Pillow, Memory Foam: Best for Contouring Comfort

• Same U-shaped design and 6 inch height as the latex version
• About 75% shredded memory foam and 25% polyester fiber
• Adjustable through the interior zipper
• Medium-firm feel according to independent coverage
• Same removable cover and five-year warranty as the latex model

Best for: sleepers who want the pillow to mold around the head and neck. Skip if: you run hot or you like to flip positions often.

Shredded memory foam responds slowly, so the pillow forms a shallow cradle around your head and holds it. That can feel luxurious and pressure-relieving, particularly if you are a mostly still sleeper. Because the foam is in small pieces, it is less dense than a solid block and easier to adjust, which makes this version a more flexible answer to the “foam pillow hurts my neck” problem than traditional contour pillows.

The cost of that feel is heat and slower recovery. If you turn from side to back during the night, the foam may take a moment to rebound. Choose this version if you primarily stay on your side, and the latex version if you are a combination sleeper.

Pros: contouring feel; adjustable; same shape as latex; sturdy construction. Cons: warmer; slower rebound; still a premium price.

3. Avocado Organic Side-Sleeper Pillow: Best Natural Alternative

• Adjustable loft by adding or removing Dunlop latex and kapok fill
• Medium-firm neck support, per the listing
• Organic positioning with natural materials
• Exact dimensions: not listed in the information we reviewed
• Cover and certifications: check the maker page

Best for: shoppers who prefer natural fills and are willing to pay for them. Skip if: you want the lowest price.

Avocado’s pillow is the nearest rival in spirit: a side sleeper pillow with adjustable fill and a latex component. The kapok adds softness, so the feel is a little more plush than pure latex noodles. If you chose the Eli & Elm latex model for its natural-feeling fill, this is the cross-shop to run.

The same warnings apply: it is not suitable for latex allergies, and the price is high. The listing’s lack of a cutout detail means you should check the shape carefully if the shoulder cutout is your priority.

Pros: natural materials; adjustable; medium-firm; brand focus on organic products. Cons: price; shape details less clear; latex content.

4. Coop Home Goods Original Cut-Out Adjustable Pillow: Best Close Rival

• Queen size 18 x 28 inches, per the listing
• Memory foam fill with an adjustable design
• Cut-out for neck and head support
• Firmness: depends on fill; check maker page
• Cover details: check the product page

Best for: anyone who wants a cut-out pillow with memory foam and adjustable fill. Skip if: you dislike new-foam smells.

Coop’s cutout pillow is the most direct comparison to Eli & Elm’s memory foam model. Both are queen-sized at about the same footprint, and both can be adjusted with a zipper. The difference is mostly in feel and brand preference, and in how each describes its fill, so it is worth reading both product pages and comparing the loft ranges.

If you are torn between the two, consider your sleeping temperature and your return policy comfort. Both are premium, so being able to send one back matters.

Pros: adjustable; cut-out shape; known brand in adjustable pillows; memory foam comfort. Cons: premium; foam odor out of the bag; warm.

5. Sidney Sleep Adjustable Curved Pillow: Best Value Curved Design

• Curved cervical shape for neck and shoulder support
• Comes with extra shredded fill so you can adjust the height
• Marketed for side and back sleepers
• Dimensions and cover: not listed in the information we reviewed
• Single pillow

Best for: people who want the curved shape without paying premium prices. Skip if: you prefer a pillow with a clear zipper-liner design.

The Sidney Sleep pillow takes a different shape from the U-cutout: it uses a gentle curve that supports the neck and lets the shoulder fall naturally. The extra fill is important because curved pillows often arrive too tall or too short. Being able to add or remove fill lets you experiment cheaply.

It will not feel as refined as the Eli & Elm, but it is a practical way to learn whether you like this style before spending more.

Pros: costs less; extra fill included; curved support; adjustable. Cons: fewer published details; build quality less documented; fill may need regular fluffing.

6. KUCEY Cooling Side Sleeper Pillow: Best Cooling Shredded Foam

• Shredded memory foam in a curved design
• Marketed for neck and shoulder support with a cooling cover
• Designed for side sleeping
• Cover fabric and fill weight: not listed in the information we reviewed
• Adjustability: depends on zipper design; check the page

Best for: hot sleepers who still want foam. Skip if: you need a known-brand warranty.

KUCEY targets the same buyer as the Eli & Elm memory foam model with a lower price and a stronger emphasis on cooling. As with all cooling covers, the benefit is more about how the fabric feels on contact than a change in the foam beneath, so keep expectations realistic.

Pros: cooler cover; curved design; lower cost than premium models; shredded foam. Cons: fewer details; unknown long-term durability; less established warranty.

7. LOFE Organic Pillow with Cotton Case: Best for a Cotton Shell

• 20 x 26 inches, per the listing
• Organic cotton shell with a cotton case
• Adjustable loft for side sleepers
• Fill type: see maker page
• Cutout: none

Best for: shoppers who care mostly about the cotton cover and adjustability. Skip if: the shoulder cutout is non-negotiable.

Shoppers who search for a cotton side sleeper pillow often want the natural feel of a cotton shell rather than a cutout design. LOFE is a more traditional rectangle with an adjustable fill, so you gain simplicity but lose the cutout. It sits closer to a standard pillow than to the Eli & Elm.

Pros: cotton shell; adjustable; simple shape; appealing for natural-material shoppers. Cons: no cutout; less specific support; fill details not listed here.

Eli & Elm Latex vs Memory Foam: Direct Comparison

If you remain unsure, ask what bothered you about your previous pillow. If it was heat, choose latex. If it was lack of cradling, choose memory foam. If it was height, either version works because both are adjustable.

Who Should and Should Not Buy It

The Eli & Elm side sleeper pillow suits a fairly specific person: someone who spends most of the night on their side, has found standard rectangular pillows either too tall or too flat, and wants to tune the height rather than accept whatever the factory chose. The shoulder cutout is the main design idea, and it only pays off if you actually sleep with your shoulder tucked toward the pillow. If you mostly sleep on your back, the 6 inch height and the scooped edge may feel intrusive, and a lower, flatter pillow is usually a better match.

It is also worth being realistic about the footprint. A queen at roughly 18 by 28 inches is a little smaller than a standard bed pillow, which most people prefer for a side sleeper pillow because it keeps the shoulder on the mattress. The king, at about 32 inches wide, gives more room to shift your head without leaving the pillow. Couples sharing a bed should check how two of these sit side by side; the cutouts face the sleeper, so there is no need to leave a gap, but the pillows can crowd the centre of a smaller bed.

Finally, think about the long run. Fill-adjustable pillows can be refreshed by adding fill, which gives them a longer useful life than a sealed foam pillow, and the five-year warranty reported by independent coverage supports that idea. Even so, noodles and shredded foam both soften with use, so plan to refluff the pillow every few weeks and expect to top up the fill after a year or two.

One more practical point: because both Eli & Elm fills are adjustable, the real decision is less about height and more about feel and temperature. Start with the full fill for the first three nights, remove a small handful only if your head feels pushed upward, and keep removed fill in a bag so you can add it back if the pillow ends up too low.

Also Consider

• MONSAO Side Sleeper Pillow with Arm Hole: adds an arm hole, which helps if your lower arm goes numb under the pillow.
• Uowuoiw Side Sleeper Pillow with Arm and Ear Hole: a cooling memory foam pillow with cutouts for the arm and the ear.
• DMI U-Shaped Side Sleeping Pillow: a U-shaped side sleeper pillow that also doubles as a pregnancy pillow.
• Cozyplayer Adjustable Cervical Pillow: a contoured cervical pillow at a lower price for those who prefer a firm contour.

How We Chose

This guide is research-based. We did not personally use these products. We compared the brand’s published specifications, retailer listings, and independent coverage of the Eli & Elm pillow, then selected rivals that match its main features: side sleeper design, adjustable loft, and either a cutout or a curved shape. Where a detail such as dimensions, cover fabric or fill weight was not available, we wrote “not listed.”

We limited each brand to two products and kept every pick on intent. Price is shown as a tier only. Nothing here is a claim about treating pain or other conditions.

Buying Guide

Loft and shoulder width

A side sleeper needs a pillow whose height roughly equals the distance from the ear to the outer shoulder. The 6 inch Eli & Elm will suit many adults with average to broad shoulders. If you are narrow-framed, expect to remove fill. Broad-shouldered sleepers may want to keep all fill and consider a slightly taller pillow.

Cutout or curve

A cutout lets the shoulder tuck in; a curve supports the neck and lets the shoulder rest below. Cutouts are more targeted for side sleepers, while curves allow more movement. Try to match the shape to how you actually sleep.

Fill: latex, foam or natural blends

Latex is springy and cooler, foam is contouring and warmer, and kapok blends are plush. Choose based on temperature and feel. Skip latex if you have an allergy.

Cover and washing

Removable covers are a hygiene advantage. Check whether the cover is machine washable, and remember that the fill cannot usually be washed.

Warranty and returns

Premium pillows tend to have trial periods and warranties. Read the terms before buying, because a pillow is highly personal.

Common Mistakes

• Skipping the adjustment: not removing fill when the pillow feels too tall.
• Buying latex without checking for sensitivity.
• Judging after one night. Give it a week.
• Putting the cutout on the wrong side, away from the shoulder.
• Washing the fill when only the cover is washable.

Frequently Asked Questions

Is the Eli & Elm side sleeper pillow worth it?

It is worth considering if you are a side sleeper who wants an adjustable, U-shaped pillow and are comfortable paying a premium. If you want to spend less, curved alternatives like Sidney Sleep offer a similar idea at a lower price.

What is the difference between the latex and memory foam versions?

The latex version uses cooling Dunlop latex noodles and feels springier, while the memory foam version uses shredded foam and feels more contouring. Both share the same 6 inch U-shaped design.

Is the Eli and Elm pillow made of cotton?

Only the cover is a blend that includes cotton, listed at around 37 percent cotton with polyester and spandex. The fill is latex or memory foam with polyester.

Can I adjust the height of the Eli & Elm side sleeper pillow?

Yes. An interior zipper lets you add or remove fill. Remove a little at a time and sleep on it for a night before removing more.

Can I wash the pillow?

The cover can be machine washed in cool water and dried on low according to published care instructions, but the fill should not be put in a washer or dryer.

Does it help with neck pain?

A pillow that matches your shoulder width can make sleeping more comfortable, but it does not treat neck pain. If pain persists, consult a doctor or physical therapist.

What size should I buy?

Queen is about 18 by 28 inches and suits most single sleepers. King is about 18 by 32 inches and suits people who move around or share more space.

Which One Should You Buy?

Choose the Eli & Elm latex pillow if you want a springy, cooler side sleeper pillow and have no latex sensitivity. Choose the memory foam version if you prefer the slow cradle and mostly stay on your side. If natural materials matter most, cross-shop the Avocado Organic Side-Sleeper. If you want a memory foam cutout, compare the Coop Home Goods model. If you want to spend less, try Sidney Sleep or KUCEY. And if a cotton shell and a simpler shape suit you, LOFE is the pick. Whichever you buy, adjust the fill gradually and give the pillow a full week before judging.
