8 Best Memory Foam Fillers to Buy in 2025

This high-density shredded memory foam filler redefines plush comfort with a performance-driven design that stands head and shoulders above basic polystyrene alternatives. Engineered from whole-piece memory foam cuts, it delivers superior body contouring and pressure relief, making it ideal for users seeking long-lasting support in DIY cushions, pet beds, or rejuvenated furniture. Its non-static, odorless composition eliminates the mess and irritation common in cheaper fillers, directly solving the frustration of clumping, flatting, and chemical off-gassing.

In real-world use, the 10lb (4 cubic feet expanded) volume proves generous—enough to refill large bean bags or multiple couch cushions without compromise. The foam maintains excellent resilience, bouncing back after compression and resisting permanent deformation even after weeks of daily use in high-traffic seating. It performs exceptionally on body-conforming applications, like lumbar pillows and dog beds, where viscoelastic support reduces strain. However, due to its dense nature, it may feel too firm for ultra-plush crafts like stuffed toys unless blended with softer materials.

Compared to the budget 5lb Linenspa option, this Jecqbor filler offers greater volume and consistency, positioning it as the best overall choice for serious home refills and long-term projects. While the Hem Dgpsy gel version brings cooling benefits, this model wins on pure comfort and health safety, being free from dyes and additives. It’s perfect for health-conscious families, pet owners, and DIYers who prioritize sustainable softness and structural integrity—a premium upgrade that outperforms mid-tier competitors in both fluff retention and material purity.

For budget-savvy crafters and quick-fix refills, this 5lb shredded memory foam delivers surprising comfort and resilience without breaking the bank. Its high-rebound foam structure ensures it springs back after compression, making it a smart pick for cushion revival and small pet beds where support matters. The non-toxic, odorless formulation addresses a major pain point—chemical smells in foam products—giving peace of mind for indoor and child-friendly use.

Packed in a vacuum-compressed format, it expands to about 2 cubic feet, ideal for 2–3 standard throw pillows or a single floor pouf. Real-world testing shows it holds up well in moderate-use settings, like guest room cushions or kids’ bean bags, though it may flatten slightly faster than high-density options under constant weight. It’s easy to dispense and sew in, with minimal dust or residue, streamlining DIY repairs. However, it’s not recommended for large furniture like full-sized bean bag chairs, where volume and long-term loft are critical.

When stacked against the 10lb Jecqbor model, this one trades capacity and longevity for affordability and simplicity. It’s a smarter fit than bulkier options for occasional users or craft hobbyists needing just enough premium filling for a few projects. While the Linenspa version offers certification, this one wins on value per pound and ease of use, making it the best budget-friendly memory foam filler for light-duty, comfort-focused applications.

Tailor your sleep like a pro with the Coop Home Goods Extra Oomph Fill, a specialized memory foam refresher engineered for precision pillow customization. This cross-cut, medium-density foam isn’t just stuffing—it’s a sleep optimization tool, designed to boost airflow by 50% and deliver targeted neck and head support for side, back, and stomach sleepers alike. Its CertiPUR-US and GREENGUARD Gold certifications make it a top-tier choice for health-focused users, especially those battling neck pain or sleep disruption.

In testing, the breathable, lightweight foam integrates seamlessly into adjustable pillows, adding cloud-like lift without overheating—a major win for hot sleepers or menopausal women seeking cooler, deeper rest. The slow-rebound viscoelasticity molds gently to head shape, reducing pressure points and eliminating the “flat pancake” effect common in aging pillows. It’s simple to install: unzip your pillow cover, mix in the refill, and reseal. Still, it’s not intended as a standalone filler for large items, and overstuffing can compromise comfort.

Compared to generic shredded foam, this Coop refill is purpose-built for sleep wellness, outperforming multipurpose options like Welacer or RAINFLOW in support accuracy and air circulation. While cheaper fillers may work for crafts, this one is the clear leader for pillow-specific use, combining medical-grade safety, superior fluff retention, and ergonomic design. For anyone invested in long-term sleep quality, it’s the best investment in pillow longevity and comfort—a performance-focused refill that punches above its weight.

If you run hot and crave cooling comfort without sacrificing support, the Hem Dgpsy gel-infused memory foam is a game-changer in temperature-regulated filling. This 10lb shredded gel foam leverages thermally conductive gel particles to dissipate body heat, making it ideal for cooling pillows, summer bean bags, or pet beds in warm climates. With a firmness rating of 8/10, it offers solid contouring support, perfect for users who dislike sinking into overly soft, marshmallow-like fills.

In real use, the gel infusion delivers a noticeably cooler feel, especially when paired with a breathable or chilled pillow cover—a smart hack for night sweats or daytime lounging. The foam expands to roughly 4 cubic feet, filling large furniture with consistent density. While it has a slight initial gel odor, it dissipates within 3–5 days and poses no health risk. One caveat: the slower rebound time means it takes longer to regain shape after compression, which may frustrate users wanting instant fluff.

Against non-gel competitors like Jecqbor, this model trades pure softness for thermal performance, making it the best cooling gel memory foam filler on the list. It outcools the Linenspa and Welacer options while maintaining CertiPUR-US certification and broad application. Though pricier than basic fills, it’s a smart upgrade for heat-sensitive users, offering a unique blend of support, safety, and temperature control—a standout for those who prioritize cool, customized comfort over generic plushness.

For purists who want 100% real memory foam—no gel, no additives—this Welacer 10lb filler is a clean, minimalist dream. Its untreated, high-density shredded foam boasts natural viscoelasticity, molding softly to body shape while resisting long-term compaction—ideal for users avoiding synthetic cooling agents or chemical enhancements. The neat, larger shred size reduces dust and broken residue, a major plus for clean DIY projects and sensitive users.

With 5lbs expanding to 2 cubic feet, you’ll need two bags for large furniture, making it better suited for pillows, crafts, or partial refills than full bean bag overhauls. In testing, it delivered consistent softness and slow rebound, perfect for plush toys and lumbar cushions where gentle support is key. However, its non-washable nature and color randomness may deter users wanting uniform, cleanable fills. Also, like most vacuum-packed foams, it requires manual separation after expansion.

Compared to the gel-heavy Hem Dgpsy model, this Welacer option is the best non-gel alternative, prioritizing material purity and simplicity over temperature control. It’s a smarter pick than mixed or treated foams for allergy-prone households or eco-conscious crafters. While the Jecqbor offers more volume, this one wins on clean shred quality and chemical-free assurance, making it the top choice for natural, no-frills memory foam filling—a quiet performer for those who value authentic comfort over bells and whistles.

The Linenspa shredded memory foam stands out with its triple threat of certification, consistency, and choice, making it the best certified quality option for discerning DIYers. Backed by CertiPUR-US certification, it guarantees low emissions, no harmful chemicals, and durable performance—a must-have for parents, pet owners, and eco-aware users. Available in 2.5, 5, or 10lb bags, it offers flexible sizing to match any project, from tiny plush toys to full bean bag chairs.

In hands-on use, the mixed shred texture provides a balanced blend of softness and support, expanding reliably and holding shape well over time. It’s excellent for re-fluffing flat pillows or pet beds, with minimal odor and no static cling. The vacuum-packed design saves space but demands careful opening—preferably inside a box or bag—to avoid a messy foam explosion. While it lacks gel cooling or ultra-premium density, it delivers dependable, middle-of-the-road performance across all applications.

Stacked against QUTOOL or RAINFLOW, this Linenspa model offers superior scalability and trustworthiness thanks to its certification and brand reputation. It doesn’t specialize like Coop or Hem Dgpsy, but it excels as a reliable all-rounder, outperforming uncertified competitors in material safety and consistency. For users who want peace of mind with performance, it’s the smartest general-purpose memory foam filler—a trusted, certified workhorse that balances quality, variety, and real-world usability.

Sometimes, you don’t need a mountain of foam—just a precise boost to revive a sagging pillow or patch a thin cushion. That’s where the QUTOOL 0.44lb (200g) memory foam pack shines as the best small-quantity filler for targeted fixes. Made from mattress-grade shredded foam, it offers excellent rebound and long-term shape retention, perfect for minor repairs, craft samples, or mixing with existing fills.

Despite its tiny size, it expands significantly when released from vacuum packing, delivering surprising volume for spot refills. It’s ideal for plumping up a favorite travel pillow, refreshing a car seat cushion, or testing foam texture before bulk buying. The breathable cube-cut design enhances airflow and comfort, and the no-mess packaging tip—using a garbage bag during expansion—shows thoughtful user insight. However, it’s far too little for large projects, and buying multiple packs becomes costly compared to bulk options.

Compared to the 5lb Linenspa or Jecqbor models, this QUTOOL pack is not a primary solution but a precision tool. It’s the ideal starter or supplement for crafters, renters, or minimalists who need just enough premium foam without overcommitting. While RAINFLOW offers a similar small size, QUTOOL wins on brand clarity and customer support, with a 24-hour response guarantee. For small-scale, high-impact comfort upgrades, it’s the most practical micro-fill option—a smart, focused solution for targeted fluffing.

Crafters and DIY hobbyists will love the RAINFLOW 8.47oz (240g) shredded memory foam—a compact, clean, and versatile filler designed for precision arts and small projects. Made from 100% pure memory foam, it delivers a soft, slow-recovery feel that’s perfect for plush toys, custom pillow inserts, or refilling thin couch cushions without overstuffing. Its low-debris shred design ensures a tidy workspace, a rare win in the often-messy world of foam filling.

In real use, this amount is ideal for one or two small crafts, like a child’s stuffed animal or a lumbar pillow. The foam expands naturally and requires gentle hand separation, but doesn’t create the dust storm some cheaper foams do. While it’s not meant for furniture revival, it excels in controlled, creative environments where clean handling and soft texture matter. One limitation: the small weight may mislead bulk buyers, so double-check before purchasing.

Against QUTOOL’s 0.44lb pack, this RAINFLOW option offers slightly more volume and a cleaner presentation, making it the best for crafts & DIY on tight budgets. It lacks certifications like Linenspa’s, but compensates with user-friendly packaging and minimal residue. For hobbyists, teachers, or parents doing small projects, it’s the most practical, mess-free choice—a nimble, focused filler that turns creativity into comfort, one tiny project at a time.
