Lull Mattress Reviews 2026
Lull Mattress Reviews 2026: Lull's three Amazon mattress models suit sleepers who want a medium-firm, cooling foam or hybrid bed. Firmness complaints and fiberglass reports hold it back. We rated it from its Amazon listings, specs and buyer feedback on our six criteria.
Our verdict: Cautious 62/100
Cooling gel foam, a medium-firm feel and a solid 4.5 rating make it a safe pick, but firmness complaints and fiberglass reports keep it from standing out. Based on 3 models, 565 Amazon reviews, 107 search results and 19 buyer questions.
The verdict
Is Lull worth buying?
CautiousHow it scores
Our score62/100
We think the Lull mattress is a reasonable buy for back and side sleepers who want a medium-firm bed with a cooling top layer. The line is three models: the Original 10", the Original Premium 12" and the Luxe Hybrid 13". All three carry a 4.5 average, and the line's 565 Amazon reviews sit almost entirely on one model, the Original 10" (184 reviews). The other two have very few ratings, so their scores say little.
The listings describe five or six layers, a 1.5-inch gel-infused memory foam top and a medium-firm feel. The Premium and Luxe add individually wrapped pocket coils.
Our main reservation is the pattern of complaints outside Amazon. Reddit buyers describe a bed that felt much firmer than advertised, and two threads report fiberglass-like fibers leaking from the cover. Amazon doesn't state a warranty for these listings, so check the terms before you commit. If you sleep hot and like a firm-ish foam feel, it fits. If you want a plush bed, look elsewhere.
- Hot sleepers who want gel-infused foam
- Back sleepers who like medium-firm support
- Couples who want less motion transfer from the pocket-coil models
- Buyers who want a mattress-in-a-box in six sizes
- Anyone who wants a soft, plush feel
- Buyers who need a stated warranty on the Amazon listing
- Shoppers sensitive to fiberglass concerns
Who is behind Lull
Lull is a mattress brand whose contact page lists a Santa Barbara, California presence, a support phone line and an email address, with support hours on weekdays. Beyond that, what we found about the company is thin, and we won't pad it.
The Amazon listings we read don't state a warranty, so we don't claim one. The brand's own site advertises a lifetime warranty and a 365-night trial, but those are the brand's claims outside Amazon, and Amazon's standard return policy applies to Amazon orders unless a listing says otherwise.
Outside coverage is mixed. Trustpilot shows a 2.5 out of 5 TrustScore from only six reviews, too few to lean on. On Reddit, one buyer called it the most comfortable mattress they had ever slept on, while others reported poor customer service on a bed frame purchase and fiberglass leaks. Amazon ratings are the steadier signal here, and they are good.
The line
Lull's models and how they differ
All three models share the same core idea: a medium-firm bed with a 1.5-inch gel-infused memory foam top layer and an open-cell structure meant to move heat away. Each comes in six sizes, from Twin to California King, and the listings state a weight of 55 pounds for the King.
The choice comes down to height and construction. The Original 10" is the base model with five layers. The Original Premium 12" adds thickness and, per the listing, individually wrapped pocket coils over a 6-inch support core. The Luxe Hybrid 13" goes to six layers and leans on motion isolation for couples.
The Original 10" carries nearly all the review weight, so it is the best-evidenced choice. The two taller models have almost no rating history on Amazon.
Original 10" Mattress
The base model and the one buyers have rated most: 4.5 stars from 184 reviews. The listing describes five layers with cooling gel foam and a medium-firm feel pitched at back, side and stomach sleepers. It's the safest starting point in the line.
Luxe Hybrid 13" Mattress
The tallest model, with six layers and pocket coils under memory foam. The listing pitches it at hot sleepers and couples, citing motion isolation and pressure relief. Only 2 reviews so far (4.5 stars), so there's little buyer evidence either way.
The models side by side
| Model | How it differs | Rating | Reviews | On Amazon |
|---|---|---|---|---|
| Original Premium 12" Mattress | thicker 12-inch version of the Original | 4.5★ | 5 | View on Amazon |
| Original 10" Mattress | 10-inch base model with five layers and cooling gel | 4.5★ | 184 | View on Amazon |
| Luxe Hybrid 13" Mattress | 13-inch Luxe hybrid construction | 4.5★ | 2 | View on Amazon |
Medium-firm on paper, firmer for some
The listings call all three models medium-firm, and the Original 10" listing says 5 to 7 on the firmness scale, aimed at back, side and stomach sleepers. Buyer reports don't fully agree. One Reddit buyer said the bed felt as hard as a brick, far firmer than advertised, and one review site listed too-firm complaints and low edge support as cons. Lighter side sleepers should be cautious. Back sleepers are the most natural fit.
- Advertised as medium-firm, 5 to 7 out of 10
- Some buyers find it much firmer than described
- Back sleepers fit best; light side sleepers should be careful
Cooling gel is the headline feature
Cooling is the pitch on every listing. Each model has a 1.5-inch viscoelastic memory foam top with gel polymer beads and an open-cell structure intended to disperse heat. The Luxe Hybrid listing specifically targets hot sleepers, and the pocket coils in the Premium and Luxe should add airflow. We can't say how much cooler it sleeps than other beds, because the listings give no temperature figures. Check the layer description on the exact model you pick.
- Gel-infused foam top on all three models
- Hybrids add pocket coils for airflow
- No measured temperature data in the listings
Fiberglass reports are the sore spot
The Luxe Hybrid search listing mentions CertiPUR-US certification, but the Amazon listing text we read for the other models doesn't state it, so check each page. The bigger concern is fiberglass. Two Reddit threads describe fiberglass-like fibers leaking from under the cover, and buyers also ask online whether Lull mattresses contain fiberglass. These are individual reports, not a proven pattern. If you have children or sensitivities, read the listing closely and ask before buying.
- CertiPUR-US is stated for the Luxe Hybrid in search coverage only
- Two Reddit buyers report fiberglass-like fibers
- Off-gassing time isn't stated in the listings
One foam-forward line with hybrid options
Lull's three models sit in the foam and foam-hybrid camp. The Original 10" is built from gel memory foam, supportive foam and individually wrapped springs per its listing. The Premium and Luxe are described as hybrids, memory foam over pocket coils. There's no traditional innerspring here. If you want a bouncy, coil-forward feel, this line is foam-led, with coils under the comfort layers.
- Foam-led construction across all three
- Premium and Luxe are pocket-coil hybrids
- No classic innerspring option
Longevity isn't proven yet
The Premium listing describes a 6-inch polyurethane core meant to prevent sagging, but that's a brand claim. Buyers elsewhere give mixed signals: online coverage mentions people loving the comfort and others reporting pain or sagging after a few years, and one writer described fixing a sagging Lull. With no warranty stated on Amazon, you can't lean on one to cover it.
- 6-inch support core claimed to resist sagging
- Some owners report sagging after years
- No Amazon warranty stated
What Lull owners say
Amazon ratings are strong at 4.5 stars, while Reddit threads run more mixed.
- One Reddit buyer called it the most comfortable mattress they had ever been on, praising the out-of-box feel.
- Reviewers on Lull's own site and in test coverage point to good motion isolation, useful for couples with a restless partner.
- The 4.5 average across 565 Amazon reviews says most owners are satisfied.
- Some buyers say a bed sold as medium-firm felt very hard, and one review site noted low edge support.
- Two Reddit threads report fiberglass-like fibers leaking from the cover.
- One buyer was dissatisfied with Lull's bed frame and customer service.

Alternatives
When another brand fits better
If you want a soft, plush feel, look for a brand that lists a lower firmness number and a thicker comfort layer, since Lull's models are pitched medium-firm and some buyers find them harder. If a stated warranty on the Amazon listing matters, pick a brand that spells out coverage and its sagging threshold. If fiberglass worries you, look for a listing that explicitly says the cover is fiberglass-free. And if you want a bouncy, coil-forward bed, choose an innerspring or a hybrid with a thicker coil system.
FAQ
Lull questions buyers ask
01 Is Lull a good mattress brand?
Mostly yes on Amazon: the line averages 4.5 stars across 565 reviews, with the Original 10" carrying most of them. Reddit is more mixed, with complaints about firmness, fiberglass and customer service. It suits buyers who want a medium-firm cooling foam bed.
02 Do Lull mattresses contain fiberglass?
The listings we read don't mention fiberglass. Two Reddit threads, though, describe fiberglass-like fibers leaking from under the cover. These are individual reports. If it concerns you, ask the seller about the fire barrier before ordering.
03 How firm is a Lull mattress?
The listings call it medium-firm, and the Original 10" listing gives a range of 5 to 7 out of 10. Some buyers say it felt much firmer, and one review site mentions too-firm complaints. Back sleepers usually fit best.
04 How many Lull mattress models are on Amazon?
Three: the Original 10", the Original Premium 12" and the Luxe Hybrid 13". Each comes in Twin, Twin XL, Full, Queen, King and California King. The Original 10" has by far the most reviews.
05 Which is better, Lull or Nectar?
We didn't compare them head to head here. Lull's strengths are the cooling gel foam and a 4.5 Amazon rating. Check Nectar's own listing for firmness, layers and warranty terms, then weigh them against the Lull model you're considering.
06 How long do Lull mattresses last?
No lifespan is stated on the Amazon listings. The Premium listing describes a 6-inch support core meant to resist sagging, but some online buyers report sagging after a few years. Treat durability as unproven for now.
Where to buy Lull
Amazon is where we read the line: three mattress models, each in six sizes. Check the listing for the size you want, since the pages differ by model. We don't quote prices here, so see Amazon for current pricing. Look at the return terms and any warranty wording on the exact listing before you order, because none is stated on the pages we read.
