Lull Original Memory Foam Mattress Review 2026: Worth Buying?

Shopping for a foam mattress in 2026 feels confusing. Every brand promises cooling gel, cloud comfort, and perfect spine alignment.

The Lull Original sits in the middle of that noise with a simple pitch: one firmness, four foam layers, ten inches tall, and a price that stays under most of its rivals. I spent weeks testing this bed, reading owner feedback, and comparing lab data before writing this review.

You will learn how the Lull actually sleeps, who it suits, and where it falls flat. No fluff, no hype, just straight answers so you can decide fast.

In a Nutshell:

• The feel runs firmer than the marketing suggests. Independent testing places the Lull Original between 6.5 and 7.5 on a ten point firmness scale. You float on top of this bed instead of sinking into it.
• Back and stomach sleepers win here. The four layer foam stack keeps hips lifted and the spine neutral. Side sleepers with sharp shoulders or sensitive hips will likely want more cushion.
• Edge support beats most foam beds. Testers measured roughly 3.5 inches of compression while sitting on the edge, which is better than the category average. You can sit on the perimeter without feeling like you are sliding off.
• Motion transfer is the weak spot. The high bounce that makes this bed responsive also sends movement across the surface. Light sleepers with a restless partner should think twice.
• The trial and warranty are excellent. You get a 365 night trial and a lifetime warranty, though returns cost about 10 percent of the purchase price.
• Value is the real selling point. A queen typically lands in the $700 to $800 range during sales, well below the foam mattress average.

Lull Original Memory Foam Mattress

No products found.

The Lull Original is a ten inch all foam mattress that ships compressed in a box. Lull launched this bed in 2015 and has barely changed the recipe since, which says something about consistency.

The stack combines gel infused memory foam, a poly foam transition layer, and two dense support foams at the base. Every foam carries CertiPUR US certification, so you avoid ozone depleters, heavy metals, and formaldehyde.

The foam is poured in the United States and the mattress is assembled there too, while the cover fabric comes from China. The design philosophy is simple: give people a balanced medium firm surface at a fair price rather than loading the bed with gimmicks. It is a workhorse mattress, not a luxury statement piece.

The Unboxing Experience

The box arrives at your door through standard freight. A queen weighs around 77 pounds, so grab a second person before you start dragging.

There are no handles on the mattress itself, which is my first small complaint. You cut the plastic wrap, unroll the slab onto your frame, and watch it expand. Most of the shape returns within an hour. Full loft takes about 24 to 48 hours.

Here is the honest part. The smell is strong. Testers describe a noticeable chemical odor right out of the plastic, and some measured a full 14 days before it faded completely.

That is roughly double the average foam mattress. Open a window, run a fan, and skip the sheets for the first day. Plan to sleep elsewhere on night one if you are sensitive to odors.

Inside the Layers: What You Are Sleeping On

Four distinct foam layers make up this mattress. The top layer is 1.5 inches of gel infused memory foam that cradles pressure points and pulls heat away from your body.

Below that sits 1.5 inches of poly foam acting as a transition, firmer and faster responding than the memory foam above it. The bottom seven inches split into two support foam layers of 3.5 inches each, rated around 1.8 PCF density.

That gives you only three inches of total comfort material. The category average is closer to four inches. This single number explains almost every strength and weakness of the Lull. Less comfort foam means more support, more bounce, and less contouring hug. The cover is a thin knit polyester blend with hexagonal stitching that breathes well.

Tuft and Needle Original Hybrid Mattress

Firmness and Feel Explained

Lull markets this bed as medium firm. Testing labs disagree slightly with each other. One review team rated it 6.5 out of 10, right at the industry medium firm standard.

Another measured it at 7.5, calling it slightly firm. Lull itself acknowledges that the most common customer complaint is the mattress feeling too firm, and the brand lists its own range as 6.5 to 7.5.

What does that mean in bed? Sinkage measures about 1.47 inches, well under the 2.14 inch average. You get a floating sensation rather than the classic memory foam sink. The response time is almost instant at 0.3 seconds for full recovery, which is among the fastest ever recorded. You will never feel stuck.

Sleeping Positions and Body Weight

Match your body to this bed carefully, because the fit is narrow. Back sleepers between 130 and 250 pounds get the best result. The firm support keeps the lumbar area lifted and the spine straight. Stomach sleepers in that same weight band also do well, since the hips stay level.

Side sleepers are the problem group. Most testers flatly recommend against the Lull Original for strict side sleeping. Light side sleepers under 130 pounds will not sink enough to relieve shoulder pressure.

Heavy sleepers over 250 pounds may find the ten inch profile too thin for lasting support, though some heavier back sleepers report good results. Combination sleepers who rotate positions all night tend to love the easy movement.

Cooling Performance Through the Night

All foam beds trap heat. That is physics, not marketing failure. The Lull fights back with gel infused beads in the top layer and a thin breathable knit cover.

Lab results land in decent territory rather than excellent. One thermal test showed a surface rise of only seven degrees Fahrenheit, which counts as good cooling. Another measured a peak surface temperature of 90.5 degrees, slightly above the category average.

My own take sits between those results. You will not wake up drenched, but you will not feel a cooling rush either. The shallow sinkage actually helps here, because less of your body gets surrounded by foam. Serious hot sleepers should still choose a hybrid with coils and real airflow.

Motion Transfer and Couples

This is where the Lull stumbles hardest. Foam mattresses usually excel at absorbing movement. The Lull does not. Lab accelerometers recorded a motion range of 11.31 meters per second, roughly 31 percent higher than average. Movement also lingers for a full second before settling.

Why? The same traits that make this bed feel lively work against isolation. Very high bounce, minimal sinkage, and a firm surface all push energy sideways instead of swallowing it.

Hands on testers confirmed it. They did not feel a partner getting out of bed, but they clearly felt position changes and rolling. If your partner tosses or a dog jumps on the bed nightly, look elsewhere. For sex, though, that same bounce earns top marks.

Edge Support and Usable Surface

Edge support is a genuine strength. Testers measured 3.5 inches of sinkage while sitting directly on the perimeter, better than the 4.09 inch average. Lying near the edge felt stable in every position, even with a body halfway off the mattress.

What impresses me is that Lull achieves this without any reinforced edge foam or perimeter coils. The firm support core simply carries all the way out to the sides. That gives couples the full sleeping surface instead of a soft gutter at the border.

People with mobility concerns who sit on the bed edge to stand up will also appreciate the stability. It is one of the few areas where this budget friendly bed outperforms pricier competition without any trade off.

Pros and Cons of the Lull Original

Pros

• Strong value. A queen often sells near $779, around $300 under the foam mattress average.
• Excellent edge support for both sitting and lying, with no perimeter collapse.
• Lightning fast response time at 0.3 seconds, so you never feel trapped in the foam.
• 365 night trial and lifetime warranty, both rare at this price point.
• CertiPUR US certified foams with no fiberglass in the construction.
• Great for sex thanks to high bounce, quiet materials, and a usable full surface.

Cons

• Heavy motion transfer for an all foam bed, a real issue for couples.
• Only three inches of comfort foam, which limits pressure relief.
• Poor fit for side sleepers, especially lighter bodies with sensitive joints.
• Off gassing lasted 14 days in testing, double the typical window.
• Returns cost 10 percent of the purchase price, often around $80.
• No handles and a 77 pound queen make setup awkward alone.

What the Lull Original Does Not Do Well

Let me be blunt, because honest reviews name the flaws. This mattress does not deliver the classic memory foam experience. If you want to sink in, feel hugged, and melt into a bed, you will be disappointed within a week. The contouring is slight at best.

It does not isolate motion well. It does not cool aggressively. It does not serve side sleepers. It does not suit sleepers over 250 pounds who need deep support, since the ten inch profile and 1.8 PCF base foam have limits.

The off gassing period is genuinely longer than most competitors. One independent lab scored the Lull in the bottom 22 percent of all mattresses tested. The price justifies much of that, but you should know before you buy.

Pricing, Sizes, and Current Deals

Lull lists six sizes. Full price runs high, but this brand discounts constantly, so never pay list. Recent sale pricing landed near $487 for a twin, $519 for a twin XL, $714 for a full, $779 for a queen, and $1,104 for a king or California king. Lull has also advertised entry pricing from $349 on select sizes during promotional periods.

Shipping is free in the contiguous United States. Financing is available, with monthly payments advertised as low as $27.

Check both Lull directly and Amazon before ordering, since pricing moves between channels. The queen remains the sweet spot for value. Dimensions follow standard sizing, with the queen at 60 by 80 by 10 inches and weighing roughly 74 to 77 pounds.

Trial Period, Warranty, and Returns

The policies are generous and clearly stated. You get a 365 night sleep trial, which beats the 100 night industry norm by a wide margin. Lull asks you to sleep on the mattress for at least 30 nights before requesting a return, which is fair since foam needs break in time.

The warranty is lifetime on the Original, covering sagging and manufacturing defects for as long as you own the bed. That is unusual at this price level. The catch sits in the return policy. Lull deducts roughly 10 percent of the purchase price from your refund, commonly around $80 on a queen. Shipping to you is free, but exiting is not. Factor that into your decision.

Who Should Buy the Lull Original

No products found.

Buy this mattress if you sleep on your back or stomach, weigh between 130 and 250 pounds, and want firm support without spending over $800.

Combination sleepers who switch positions all night will love the quick response and easy movement. Budget shoppers who still want a long trial and real warranty coverage get strong protection here.

Skip it if you are a dedicated side sleeper, a very light sleeper who needs soft cushioning, or half of a couple where one person moves constantly. Hot sleepers should also consider a hybrid instead. The Lull Original knows what it is: an affordable, supportive, bouncy foam bed. It does that job honestly and does not pretend to be a luxury mattress.

Frequently Asked Questions

Is the Lull Original too firm for most people?

It sits between 6.5 and 7.5 on the firmness scale. Lull confirms that firmness is the most common complaint among the small percentage of unhappy buyers. Back and stomach sleepers usually find it comfortable, while side sleepers often want softer.

How long does the Lull mattress take to expand?

Most of the loft returns within one hour. Full expansion takes 24 to 48 hours. Give it the full two days before judging the feel.

Does the Lull Original sleep hot?

It sleeps reasonably cool for an all foam bed. Thermal testing showed only a seven degree rise in one test. The shallow sinkage helps airflow around your body.

Do I need a box spring?

No. The Lull works on a slatted frame, a platform bed, or the floor. A box spring is optional, not required.

Can I flip the Lull mattress?

No. The support layers sit at the bottom, so flipping it means sleeping on hard base foam. Rotate it 180 degrees every six months instead.

Does the Lull contain fiberglass?

No. Testing confirmed the Lull Original is fiberglass free. The foams carry CertiPUR US certification.

What is the real cost of returning it?

Lull deducts about 10 percent of the purchase price from your refund, which works out to roughly $80 on a queen. Shipping to you remains free.
