Best Body Pillow for Side Sleepers: 5 Top Picks
If you're a side sleeper who tosses and turns chasing a comfortable position, the fix might not be your mattress at all. It might be the empty space between your knees, or the lack of something to hug through the night.
A good body pillow fills that gap, quite literally, keeping your hips, knees, and shoulders stacked in alignment so your spine doesn't twist while you sleep. The best body pillow for side sleepers should be long enough to support you from shoulder to knee, adjustable enough to match your firmness preference, and durable enough to hold its shape for years. Here are five that do exactly that.

1) Coop Sleep Goods Original Adjustable Body Pillow: The Customizable Favorite
What it is
A 20" x 54" body pillow filled with cross-cut memory foam and microfiber, encased in a machine-washable bamboo-derived cover, priced at $99.
Why it earns a spot on this list
- Fully adjustable fill via a zippered opening, so you can add or remove material to dial in your exact loft and firmness.
- Cross-cut memory foam design allows more airflow than solid foam blocks, helping it sleep cooler than traditional body pillows.
- GREENGUARD Gold and CertiPUR-US certified, so it's been independently tested for harmful chemicals.
- Machine-washable outer cover makes long-term upkeep simple.
Where it falls short
- Requires occasional fluffing to keep the shredded fill from compacting over time.
- No dedicated shape like a U or curve, so it relies entirely on adjustable fill rather than an ergonomic contour.
Best for: Side sleepers who want to fine-tune firmness themselves rather than commit to a fixed shape.
Skip if: You'd rather have a pre-contoured pillow that requires zero setup.
2) Buffy Wiggle Pillow: The Bendable, Style-Forward Pick
What it is
An 8" x 82" flexible bolster-style body pillow made from recycled fill with a removable TENCEL Lyocell cover, priced at $109 (currently discounted to $87.20).
Why it earns a spot on this list
- Genuinely flexible shape bends and knots into different configurations, so it adapts to side sleeping, back support, or between-the-knees cushioning without needing a fixed U or C shape.
- Made with recycled fill (roughly 55 recycled plastic bottles), appealing to sleepers who want a lower-impact pick.
- OEKO-TEX Class 1 certified, the strictest tier, typically reserved for infant-safe textiles.
- 50-night returns policy plus a 7-night at-home trial before your card is even charged.
Where it falls short
- No firm structure, so sleepers who want a more rigid, contoured shape may find it too floppy.
- Inner pillow is spot-clean only, unlike fully machine-washable competitors.
Best for: Side sleepers who want a versatile, tie-into-a-knot pillow that also looks good left out on the bed.
Skip if: You want a pillow with a fixed ergonomic shape rather than a flexible bolster.
3) Sleep Number Cool ComfortFit Body Pillow: The Cooling Option
What it is
A full-length body pillow filled with a blend of down-alternative fibers and memory foam pieces, wrapped in a cool-to-the-touch removable cover, priced at $119.99.
Why it earns a spot on this list
- Cool-to-the-touch outer fabric specifically engineered to counter the heat retention some body pillows are known for.
- Blended fill combines memory foam pieces with down-alternative fibers for a softer, more conforming feel than solid foam.
- CertiPUR-US certified foams, tested for content, emissions, and durability.
- Hypoallergenic construction, a plus for allergy-sensitive sleepers.
Where it falls short
- Fill isn't adjustable, so you're committed to the factory loft and firmness out of the box.
- Cover is the only washable component; the pillow itself is spot-clean only.
Best for: Hot sleepers who want a body pillow that won't trap heat overnight.
Skip if: You want to customize firmness by adding or removing fill.
4) Nest Bedding Easy Breather Convertible Body Pillow Kit: The Two-in-One Upgrade
What it is
A cover system that zips two adjustable Easy Breather pillows together into one full-length body pillow, priced at $268 for the Standard/Queen kit (2 pillows + cover), or $50 for the cover alone if you already own the pillows.
Why it earns a spot on this list
- Independently adjustable halves: since it's built from two separate Easy Breather pillows, you can fill the top half fuller for shoulder support and keep the bottom half softer for your knees.
- Reusable design means you can unzip the cover and use the two pillows separately whenever you don't need a full body pillow.
- Icecore cooling cover promotes airflow better than a standard knit cover.
- 30-night trial and 2-year warranty, generous terms for a pillow-based product.
Where it falls short
- By far the priciest pick on this list, since you're effectively paying for two premium pillows plus the connecting cover.
- Assembly required: you're zipping two pillows together rather than unboxing a single, ready-to-use body pillow.
Best for: Side sleepers who want independently customizable support for their upper and lower body.
Skip if: You want a simple, single-piece body pillow at a lower price point.
5) Snuggle-Pedic Body Pillow: The Budget Pick
What it is
A 20" x 54" shredded memory foam body pillow with a breathable, Kool-Flow bamboo-blend cover, priced at $69.99 (frequently on sale around $59.99). Note: Snuggle-Pedic sells primarily through Amazon rather than its own direct storefront, so this price is sourced from their official Amazon listing rather than a brand-owned page.
Why it earns a spot on this list
- Lowest price on this list without dropping the shredded memory foam construction found in pricier competitors.
- GREENGUARD Gold certified, an environmental and safety certification not every budget pillow carries.
- Kool-Flow bamboo-derived cover promotes breathability to help offset memory foam's usual heat retention.
- Over 12,000 ratings at a 4.6-star average, a strong track record for a budget pick.
Where it falls short
- No official brand storefront, so pricing and stock depend entirely on Amazon's listing rather than a direct-to-consumer site with its own trial policy.
- Needs occasional refluffing to prevent the shredded fill from flattening with regular use.
Best for: Budget-conscious side sleepers who want shredded memory foam comfort without a premium price tag.
Skip if: You prefer buying directly from a brand's own site with its own trial and return policy.
Frequently Asked Questions
- Do body pillows actually help side sleepers?
- Yes. A body pillow gives your top arm and top leg something to rest on instead of collapsing onto your bottom arm and leg, which helps keep your hips and shoulders stacked and your spine in a more neutral line through the night.
- What length body pillow should I get?
- Most standard body pillows run around 54 inches, which suits the average adult from shoulder to knee. Taller sleepers may want to look for extended or jumbo sizes if a standard length feels short.
- Can a body pillow replace a pregnancy pillow?
- For many people, yes. Straight body pillows work well for general side-sleeping support, though U- or C-shaped pregnancy pillows offer more targeted belly and back support for later trimesters.
