Lull Mattress Review

Lull is a US bed-in-box brand from Lull Ventures LLC, founded in 2015. It sells four medium-firm beds: the 10-inch Original all-foam, the 12-inch Original Premium, the 13-inch Luxe Hybrid and the 15-inch Premium Luxe Hybrid. Prices run roughly $499 to $1,499 and up. You get a 365-night trial and a lifetime limited warranty. It's best for budget memory foam fans who want one safe feel. It isn't for you if you need firmness choices or white-glove setup.

Back sleepers of average weight should do well on any of the four. You get alignment with light contouring, and the hybrids add coil pushback for easier movement. Lighter stomach sleepers may be fine. Heavier stomach sleepers may feel midsection sink. Independent lab testing scored stomach support 4.5 to 6.5 out of 10, depending on weight.

Average-weight side sleepers get the best fit, with lab scores of 7.5 to 8 out of 10. If you're heavier or want deep pressure relief, look at the 12-inch Premium or the 15-inch flagship for thicker comfort layers. Hybrids suit couples and combination sleepers best. One lab rated the Original line's motion isolation 7 out of 10. If you sleep hot, the gel beads and open-cell foam aim to run cooler than traditional memory foam. But one lab rated temperature control 4.5 out of 10 and noted trapped heat.

Lull doesn't offer multiple firmness levels. The brand doesn't publish per-model ILDs or cooling-test data (checked September 2026).

In September 2026, lull.com shows entry prices under an advertised 65% sitewide clearance. Original starts at $499 (advertised was $1,426, financing from $28 a month). Original Premium starts at $699 (was $1,998, from $39 a month). Luxe Hybrid starts at $999 (was $2,855, from $42 a month). Premium Luxe Hybrid starts at $1,499 (was $4,283, from $62 a month).

Luxe Hybrid by size: Twin $999 (was $2,855, 61 lbs), Twin XL $1,199 (was $3,426, 65 lbs) and Full $1,299 (was $3,712, 84 lbs). Queen is $1,399 (was $3,998, 101 lbs). King and Cal King are $1,699 each (was $4,855). King weighs 129 lbs and Cal King 126 lbs. The Original is the budget door. The Premium is the popular middle step. The Luxe Hybrid is the best value for coil support, and the 15-inch flagship charges for height and layer count.

Prices are before tax and depend on promotions, so check at checkout. The brand doesn't publish whether the was-prices are real reference prices, or its sale cadence and financing APR terms (checked September 2026).

Comfort layers across the line include gel-infused and gel-bead memory foam and quilted memory foam covers. They also include high-resilience transition foams and sink-resistant foam. The brand describes all of them as CertiPUR-US certified. The two all-foam models have high-density foam cores. The two hybrids have 8-inch foam-encased pocketed coils. Ultra-firm edge foam or a durable base layer sits at the perimeter.

Covers are stretch-knit and tufted, with handles on the hybrids. The Original has a padded stitched airflow top. Lull says the mattresses are crafted and assembled in the USA. It lists membership in the Sustainable Furnishings Council and the Mattress Recycling Council. The brand doesn't publish per-model densities, ILDs, coil gauges, adhesive or fire-barrier details or certifications beyond CertiPUR-US (checked September 2026). The only coil count it gives is 609 for the Luxe Hybrid Queen.

The outlook is mixed but backed by the warranty. Lull advertises a lifetime limited warranty. The Sleep Foundation Test Lab (October 2025) rated the Original's durability 5.5 out of 10. It estimated visible wear around the five or six year mark, with middle softening and permanent dips.

Lull claims demanding third-party assessment for durable comfort. Tufted covers and reinforced edge foam should limit shifting and edge breakdown, and hybrids add steel coil support. The warranty covers sag or indentation over 1.5 inches and cover zipper flaws. Lull covers transport for the first 10 years, then a $75 shipping and handling fee applies. The brand doesn't publish foundation or rotation rules, prorating terms or long-term independent testing (checked September 2026).

Lull advertises 50K-plus reviews at 4.6 out of 5 stars across the four models. Quoted praise covers better sleep, cool feel, less partner disturbance, morning energy and back-pain relief. The brand says it posts favorable and unfavorable comments. Per-model averages weren't shown.

The Sleep Foundation Test Lab (October 2025) scored the Original 8.6 overall at Medium Firm (6 out of 10). It's best for side sleepers, back-pain shoppers and couples. Subscores were Motion Isolation 7, Pressure Relief 7, Edge Support 6, Durability 5.5, Temperature Control 4.5 and Ease of Movement 4.5. Complaint themes from BBB, Trustpilot, Google and retailers weren't available to us in September 2026. The single medium-firm feel and foam heat are the likeliest mismatches, so use the year-long trial on purpose.

You can buy direct at lull.com, where all four models were listed in September 2026. The brand sells online-direct with email support at support@lull.com. It doesn't publish brand stores, showrooms, dealer partners, phone ordering or sibling brands (checked September 2026). We couldn't verify availability on Amazon or at department or furniture chains.

Against Casper, both sell bed-in-box memory foam and hybrid lines around a medium feel. Lull counters with a 365-night trial and a lifetime warranty headline against Casper's shorter standard terms. Against Nectar, both chase budget memory foam value with year-long trials. They differ on layer stacks and anchor pricing. Head-to-head comfort test winners aren't published (checked September 2026).

Against Purple, Lull leans on traditional contouring memory foam. Purple sells a gel grid feel. If you love foam hug, lean Lull. If you want bounce, lean Purple. Against Saatva, Lull is bed-in-box value with no white-glove or removal service. Saatva leans on premium assisted delivery. Under promotions, Lull sits budget to mid-range. If you want natural latex, organic certification or multiple firmness choices, look elsewhere.
