This lull 5 layer memory foam review examines a 10-inch mattress built with memory foam and individually pocketed coils. Two specs define its performance: a 10-inch profile and a medium firm comfort level. The construction features a 1.5-inch viscoelastic memory foam top layer infused with gel polymer beads to disperse heat, alongside a 3 core support layer of polyurethane foam. Measuring 38 by 80 inches in Twin XL, the bed weighs 44.2 pounds. It ships compressed in a box, is CertiPUR-US certified, completely fiberglass-free, and includes a 365-night home trial.
- 1.5-inch viscoelastic memory foam top layer infused with cooling gel polymer beads
- Individually pocketed coils designed to isolate motion and relieve pressure points
- 3-inch core support layer made of high-density polyurethane foam to prevent sagging
- CertiPUR-US certified foam construction made entirely without fiberglass
- 365-night trial period for evaluating the mattress at home
Good fit for
This mattress fits back, side, and stomach sleepers who want a medium firm surface with balanced contouring. The 80-inch Twin XL length suits taller individuals needing extra legroom on a 38-inch wide frame. If you sleep hot, the 1.5-inch gel polymer bead layer and open-cell foam promote airflow to regulate temperature. It also suits light sleepers, as the individually pocketed coils isolate motion across the bed.
Who can skip it
Skip this model if you need a soft, plush feel or an extra-firm sleep surface, as it comes strictly in medium firm. Couples should look elsewhere, because the 38-inch Twin XL width is built only for single sleepers. Furthermore, if you prefer a taller bed profile, this 10-inch height lacks the thicker padding found in the brand's 12-inch, 13-inch, or 15-inch alternatives.
Verdict
The Lull 10-inch Twin XL combines cooling gel memory foam and pocketed coils to provide balanced medium-firm support for solo sleepers. It delivers certified, fiberglass-free construction backed by a 365-night trial.
Key Lull Mattress Specifications Explained
Mattress Size: Twin XL
A Twin XL mattress measures 38 inches wide by 80 inches long. This gives you five extra inches of length compared to a standard twin. It suits taller individual sleepers, teenagers, and college students who need legroom in compact spaces. When shopping, compare this with standard twin models if your room is tight, or full sizes if you need wider sleeping space.
Cooling Tech: Gel polymer beads
Gel polymer beads are embedded directly into the top viscoelastic memory foam layer. They work to absorb and disperse your body heat while open-cell foam promotes airflow. This design benefits warm sleepers who usually overheat on dense memory foam. When shopping for mattresses, compare gel-infused foams against open-coil innersprings or natural latex, which provide even greater ambient ventilation across the bed.
Certifications: CertiPUR-US
A CertiPUR-US certification indicates the foam is produced without harmful chemicals. In everyday use, this means cleaner indoor air quality in your room and less chemical odor when you unbox the bed. It suits health-conscious buyers, children, and people with chemical sensitivities. When shopping for mattresses, check whether foam layers carry verified safety certifications or leave their chemical composition unspecified.
Trial Period: 365-night trial
A 365-night trial gives you a full year to determine whether the mattress supports your sleep habits across all seasons. This long timeframe benefits undecided buyers who need extended adjustment time to evaluate spinal support and firmness. When shopping for mattresses, compare this 365-night window against options offering shorter testing periods to see how much flexibility you have.
Weight: 44.2 pounds
At 44.2 pounds, this mattress is light enough for one person to unbox, maneuver, and position onto a frame. This manageable weight benefits solo movers, renters, and college students who frequently transport their bedroom furniture. When shopping for mattresses, compare this 44.2-pound build against heavier traditional innerspring beds or multi-layer hybrid options that often exceed 70 pounds and require two people to lift.
Design, Construction, and Material Specifications
According to the listing, the mattress features a five-layer build finished in a two-tone white-grey cover. The internal construction combines a 1.5-inch viscoelastic memory foam top layer infused with gel polymer beads, breathable fibers, open-cell foam, individually pocketed coils, and a 3-inch polyurethane foam core support layer. Materials used inside the mattress carry CertiPUR-US certification to verify the foam is made without harmful chemicals, and the full build is fiberglass-free.
In terms of exterior dimensions, the mattress measures 38 inches wide, 80 inches long, and 10 inches high, with a total weight of 44.2 pounds. At this weight, you can maneuver and position the mattress onto your bed frame without requiring a second person after delivery in a box. The 10-inch profile allows you to use standard Twin XL bedding, eliminating the need to purchase specialized deep-pocket sheets.
The internal layout pairs pocketed coils with high-density foam to absorb movement and distribute body weight evenly across the surface. This physical design yields a medium-firm feel that stays stable along platform bases, slatted frames, and daybed foundations. Because it concentrates full adult length into a 38-inch width, it gives you practical support in smaller guest rooms, studio apartments, or college dormitories.
Setup Requirements and Everyday Sleep Performance
The Lull mattress arrives compressed inside a box for direct delivery to your door. With a total weight of 44.2 pounds, you can handle and position the packaged unit in your room without professional assistance. Once you unbox and unroll it onto any compatible Twin XL base, the structure expands to reach its 38-inch width, 80-inch length, and 10-inch height.
During everyday use, the mattress accommodates back, side, and stomach sleepers. A high-quality polyurethane core support layer prevents sagging over extended periods, which helps maintain your natural spinal alignment. When you change positions at night, the individually pocketed coils isolate motion and relieve pressure points. This design feature prevents sleep disturbances caused by continuous shifting, making the surface practical for toddlers, kids, and adults alike.
To manage sleeping temperatures day to day, the top layer combines an open-cell foam structure with breathable fibers to promote airflow. Embedded gel polymer beads absorb and disperse accumulated body heat. The entire mattress is fiberglass-free and CertiPUR-US certified, protecting your living environment from harmful chemicals. In addition, you get a 365-night trial to assess how the medium-firm comfort level meets your daily sleeping habits throughout a full calendar year.
What to Check Before You Buy
Before purchasing, verify your bed frame supports a Twin XL profile. Because standard twin sheets measure five inches shorter, you will need dedicated Twin XL bedding and mattress protection. The mattress requires a flat foundation, platform base, or supportive slatted frame to prevent the polyurethane support core from sagging. For upkeep, the layered construction features a dedicated top memory foam layer and coil base, so you cannot flip the mattress; regular head-to-toe rotation maintains level surface wear. Keep surface cleaning limited to spot treatment, as foam layers absorb liquid. Within the wider product line, this model represents the 10-inch baseline profile across 22 variations. If you need thicker profiles, the lineup also includes 12-inch Original Premium, 13-inch Luxe Hybrid, and 15-inch Luxe Premium Hybrid configurations spanning Twin up to California King sizes.
Check before you buy
- Confirm your bed frame fits an 80-inch Twin XL foundation rather than standard twin dimensions.
- Purchase Twin XL sheets and mattress encasements to match the extended length.
- Plan for rotating the mattress head-to-toe instead of flipping the one-sided foam build.
- Compare the 10-inch build against the brand's available 12-, 13-, and 15-inch options.
