8 Best Memory Foam Mattresses Under $100 to Buy in 2025

The EGOHOME 8 Inch Twin Mattress makes a bold statement in the sub-$100 memory foam arena with its patented green tea-infused gel foam and CertiPUR-US certified construction, delivering a refreshingly cool, pressure-relieving sleep surface that punches above its weight. What sets this mattress apart is its dynamic pressure distribution system, which molds precisely to your body’s curves and minimizes joint stress—ideal for side sleepers or those plagued by morning stiffness. The special bubble-hole foam structure enhances breathability, actively pulling heat away from the body, turning hot, restless nights into cool, undisturbed rest.

In real-world testing, the 8-inch profile strikes a smart balance between support and sink, offering enough depth to cushion hips and shoulders without feeling like you’re stuck in quicksand. The medium firm feel adapts fluidly across sleep positions—back sleepers appreciate the spinal alignment, while stomach sleepers benefit from the subtle lift at the core. It performs reliably on platform beds and metal frames, though it’s not ideal for bunk beds with narrow slat spacing. While it off-gasses slightly upon unboxing (common in foams), the odor dissipates within 24 hours, and the 75-inch length is a tad short for taller users.

Compared to the thinner ZINUS 5-inch model, the EGOHOME offers superior contouring and thermal regulation, making it a better choice for those prioritizing comfort over extreme budget savings. It doesn’t have a removable cover like the PayLessHere queen model, but it compensates with more advanced cooling tech and a year-round stable foam structure unaffected by humidity. For anyone seeking premium-feeling materials and targeted pressure relief under $100, this is the standout all-rounder—offering near-luxury performance at a bargain-bin price.

The Neo Sleep 8 Inch Twin Mattress is the savvy sleeper’s secret weapon, combining cooling gel memory foam and medium firm support in a no-frills package that proves you don’t need to splurge for restorative sleep. Engineered with temperature-regulating gel swirls, this mattress combats the classic memory foam flaw: heat retention. The foam responds quickly to body contours, offering just enough sink to ease pressure points without sacrificing support—making it a strong contender for combo sleepers who shift positions often. Its CertiPUR-US certification ensures low emissions and safe materials, a critical win for allergy-prone or eco-conscious buyers.

During extended use, the Neo Sleep maintains consistent firmness across seasons, thanks to its thermally stable foam core that doesn’t soften in summer or stiffen in winter. It excels on flat foundations and daybeds, expanding fully within 48 hours with minimal odor. While the non-removable cover limits deep cleaning, the soft, seamless fabric resists pilling and feels inviting against bare skin. It handles motion transfer better than most budget foams, though it’s not quite as isolating as the Novilla 10-inch models. The 8-inch height provides solid edge support for sitting, but it lacks the plushness needed for deep contouring in heavier sleepers.

When stacked against the EGOHOME, the Neo Sleep trades some advanced cooling tech for pure affordability, making it the best budget-friendly pick for students or guest rooms. It doesn’t infuse green tea or offer a zip-off cover, but it nails the essentials: support, cooling, and safety—all at a price that feels like a steal. For those who want no-nonsense comfort without hidden toxins or sky-high costs, this mattress delivers smart, dependable sleep—proving value isn’t always measured in inches.

The ZINUS 5 Inch Memory Foam Mattress is a minimalist marvel, engineered for those who need a functional, no-fuss sleep solution under $90—perfect for dorms, trundles, or space-constrained rooms. Despite its slim 5-inch profile, it packs a trio of supportive foams, including green tea-infused memory foam, delivering a surprising level of pressure relief for such a compact build. The moisture-resistant terry cover adds a layer of practicality, making it a resilient choice for kids’ rooms or high-traffic guest beds where spills are inevitable. Its fiberglass-free, CertiPUR-certified foam ensures a safe, low-odor setup, appealing to health-conscious buyers on a tight budget.

In practice, the ZINUS shines in low-profile applications—it’s ideal for bunk beds and daybeds where height clearance matters. The medium firmness offers a flat, stable surface that’s better suited for back and stomach sleepers than side sleepers, who may miss deeper contouring. While it expands fully within 72 hours, the thinner profile means less motion isolation and a slightly firmer feel than thicker models. It performs best with slatted bases spaced no more than 3 inches apart; on solid platforms, airflow is reduced, slightly diminishing cooling efficiency.

Compared to the EGOHOME 8-inch, the ZINUS sacrifices depth and temperature control for portability and price, making it the go-to for ultra-budget scenarios where sleep duration is short or intermittent. It doesn’t compete with the Novilla’s spinal support, but it outperforms many in its class with certified materials and a durable base foam. For anyone needing a reliable, compact mattress under $90, this is the most practical entry-level workhorse—offering essential comfort without fluff or frills.

The PayLessHere 5 Inch Full Mattress is the unsung hero of budget-friendly full-size sleep, delivering green tea and gel-infused memory foam in a spacious 54″ x 75″ footprint—all while staying under the $100 threshold. This model stands out for offering full-size luxury at a twin price point, making it a game-changer for small apartments, college dorms, or first-time renters who need maximum space without overspending. The dual-layer infusion of green tea and cooling gel works in tandem to neutralize odors and wick heat, creating a clean, cool sleep environment that feels more premium than its price suggests. Its medium-firm feel balances support and softness, contouring gently to hips and shoulders without sagging.

Real-world testing reveals strong performance on platform frames and box springs, with rapid expansion (under 48 hours) and minimal off-gassing—thanks to its CertiPUR-US and Oeko-Tex compliant foams. The high-density base foam prevents bottoming out, even with frequent use, and the smooth terry cover resists pilling and static. However, the non-removable cover makes deep cleaning a challenge, and taller users may find the 75-inch length restrictive. While it lacks the height for deep pressure relief, it outperforms thinner models in even weight distribution and temperature regulation.

Against the Neo Sleep twin, this PayLessHere model wins on size and value, giving adults room to stretch without sacrificing cooling tech. It doesn’t match the Novilla’s 10-inch support, but it fills a rare niche: a full-size, cooling, certified foam mattress under $100. For budget-conscious buyers who prioritize space and freshness, this is the smartest full-size sleeper in the sub-$100 game—offering more bang (and bed) for your buck.

The PayLessHere 6 Inch Queen Mattress is a budget queen in every sense, offering queen-size sleeping space for under $75—a rarity in the memory foam world. What makes it truly stand out is its bamboo charcoal-infused memory foam, a natural odor absorber and temperature regulator that keeps the sleep surface fresh and cool night after night. The three-layer foam system—topping with high-density charcoal gel foam, a comfort layer, and a sturdy base—delivers surprisingly resilient support, especially for a mattress at this price. Its medium firm feel adapts well to average-weight sleepers, providing enough give to cushion pressure points while maintaining spinal alignment.

In real use, the mattress expands fully within 48–72 hours, faster in warmer rooms, and emits only a mild foam scent that fades quickly. The zipper-access cover is a rare luxury at this price, allowing you to remove and clean the fabric—a major win for hygiene-focused buyers. It performs best on solid or closely slatted bases, and while it doesn’t offer the deep sink of premium models, it handles motion transfer decently for a foam bed. The 6-inch height is adequate but not plush, making it better for back and stomach sleepers than side sleepers needing extra cushioning.

Compared to the Novilla 10-inch, it lacks depth and advanced back support, but it dominates in value and cleanability. While the EGOHOME offers better cooling with green tea, this model counters with bamboo charcoal’s natural freshness and a washable cover. For couples or solo sleepers who want a spacious, low-maintenance, and odor-resistant queen bed on a shoestring, this is the undisputed budget champion—delivering queen-size comfort where it counts, without the queen-size price.

The Novilla 10 Inch Twin Mattress is a cooling powerhouse, engineered for hot sleepers who refuse to compromise comfort for cost. With a breathable knitted cover and deep gel-infused memory foam core, it creates a continuous airflow system that actively pulls heat away from the body—making it the best choice for those who wake up sweaty. The three-layer foam construction includes a responsive comfort layer and high-density base, delivering full-body support with minimal motion transfer, ideal for light sleepers or shared rooms. Its reinforced edges add stability, allowing safe use right up to the perimeter—uncommon in budget foams.

Testing confirms exceptional thermal regulation, with the gel foam absorbing and dissipating heat faster than non-gel competitors like the ZINUS or Neo Sleep. The 10-inch profile provides deep contouring, cradling hips and shoulders with precision, making it excellent for side sleepers. It expands fully in 72 hours with only a faint odor, and the CertiPUR-US certification ensures long-term safety and durability. However, its heavier weight makes unboxing slightly harder, and the non-removable cover limits cleaning options.

Against the PayLessHere queen, it trades size for superior cooling and support, and compared to the EGOHOME, it offers greater depth and temperature control. While it’s not the cheapest, it delivers premium cooling performance at a near-budget price, making it the top pick for anyone who runs hot. For those who prioritize cool, undisturbed sleep with strong pressure relief, this Novilla model is worth the slight price bump—offering luxury-level breathability where it matters most.

The Novilla Twin Memory Foam Mattress 10 Inch is a targeted solution for back pain sufferers, combining deep gel-infused foam and precise spinal alignment in a budget-conscious package. Its high-density memory foam layer molds to the body’s natural curves, relieving pressure at the hips, shoulders, and lower back—key zones for chronic pain. The 10-inch multi-layer design ensures balanced support, with a responsive base that prevents sagging and promotes long-term spinal health. For those who wake up stiff or sore, this mattress offers noticeable relief within the first week of use, thanks to its slow-rebound foam that eases tension gradually.

In real-world trials, it excels in motion isolation, making it a solid pick for couples where one partner moves frequently. The knitted cooling cover enhances breathability, though it’s slightly less aggressive than the cooling-focused Novilla model (B0FM41Q81V). It expands fully in 72 hours, maintains firmness across temperatures, and holds up well under repeated use. However, its firm feel may feel too rigid for lightweight side sleepers, and the non-washable cover limits hygiene control.

Compared to the Neo Sleep, it offers far superior back support and durability, and against the EGOHOME, it delivers deeper contouring and better pain relief. While it lacks the bamboo charcoal freshness of the PayLessHere queen, it dominates in therapeutic support and long-term comfort. For anyone seeking a doctor-recommended level of back care under $130, this is the most effective option in the sub-$100 adjacent range—proving that targeted relief doesn’t require a luxury price tag.

The NapQueen 5 Inch Twin Mattress is the barebones champion of entry-level sleep, offering CertiPUR-US certified foam and a soft breathable cover at an unbeatable $70 price point. Don’t let the brand name fool you—this is a twin-sized workhorse, not a queen—perfect for kids’ rooms, dorms, or temporary setups where simplicity wins. The medium feel strikes a neutral balance, providing just enough cushioning for back and stomach sleepers while maintaining a flat, stable surface. Its OEKO-TEX certified fabric ensures a safe, hypoallergenic sleep environment, a rare plus at this price.

In testing, the mattress expands reliably within 72 hours, though colder rooms slow the process. The non-removable cover is soft and durable, but spills must be spot-cleaned—no deep washing here. It performs best on slatted bases, offering modest pressure relief but lacking the depth for side sleepers needing hip cushioning. While it doesn’t include cooling gels or infusions, the breathable knit fabric allows decent airflow, preventing extreme heat buildup.

Compared to the ZINUS 5-inch, it’s nearly identical in specs but slightly softer, making it better for younger sleepers. It doesn’t compete with the Novilla’s support or the EGOHOME’s cooling, but it nails the essentials at the lowest cost. For those who need a safe, basic, and affordable mattress fast, this NapQueen model is the most accessible gateway into certified foam sleep—delivering dependable rest where it counts, without bells or whistles.
