Lull vs. Puffy Mattress Comparison

The Puffy is better for most side sleepers, lightweight folks, and anyone who wants to sink into their bed. The Lull’s firmer surface better supports the spines of back sleepers and delivers superior support for sleepers with back pain. Both beds excel at motion isolation, making each a good choice for couples who share a bed.

Lull vs. Puffy Overview

Lull is best for…	Puffy is best for…
Back sleepers	Those with lightweight (<130 lbs) and average-weight (130–230 lbs) body types
Indecisive shoppers	People with joint pain
People who share the bed	Memory foam mattress lovers

Who Should Choose the Lull Mattress?

• Back sleepers: The Lull accommodates back sleepers of all body weights, thanks to slow-response memory foam that molds to the body without allowing too much sinkage. For more supportive mattresses, check out our list of best mattresses for back sleepers.
• Indecisive shoppers: As a Lull customer, you receive a full year to test drive your new mattress, so you don’t have to commit until you’ve tried the Lull during every season.
• People who share the bed: The Lull’s medium-firm feel works for most sleepers, so both partners are more likely to enjoy sleeping on the Lull. Plus, outstanding motion isolation properties minimize sleep interruptions.

Who Should Choose the Puffy Mattress?

• Those with lightweight (<130 lbs) and average-weight (130–230 lbs) body types: Sleepers weighing less than 230 lbs should find the Puffy comfortable. The medium-firm feel and memory foam layers provide excellent cushioning and spinal alignment for those with lightweight and average-weight body types.
• People with joint pain: The Puffy has two thick layers of memory foam that are deeply contouring to sensitive joints like hips and shoulders.
• Memory foam mattress lovers: With 4” of memory foam atop a polyfoam base, the Puffy hugs the body with a comforting, pressure-relieving cradle.

Lull vs. Puffy: Top Similarities 

• Construction: Both the Lull and Puffy are all-foam mattresses with memory foam top layers that have a traditional memory foam feel (i.e. conforming, slow responsiveness). 
• Motion Isolation: With layers of motion-dampening foam, both mattresses help couples and co-sleepers sleep soundly without feeling jostled by movements across the mattress. 
• Back Sleeper Suitability: Both beds contour to the curves of back sleepers in a way that supports the spine’s natural “S” curve, including the sensitive lumbar region.

Lull vs. Puffy: Top Differences 

• Stomach Sleeper Support: The Lull has a slightly firmer top layer that supports lightweight stomach sleepers by limiting hip sinkage. The Puffy’s softer surface isn’t firm enough for stomach sleepers of any body type. 
• Pressure Relief: The Puffy’s comfort system is both thicker and softer than the Lull’s. With more generous give at pressure points like the hips and shoulders, side sleepers and people with joint pain are likely to prefer the Puffy. 
• Suitability for Different Body Types: Because of the Puffy’s softer surface and thicker comfort layers, it’s the better choice for lightweight back and side sleepers who want pressure relief.  Since the Lull is a bit firmer, it’s better suited to average-weight side or back sleepers and lightweight stomach sleepers.

Lull vs. Puffy: Firmness & Feel Differences

The Puffy is a memory foam mattress that contours to the body for excellent pressure relief. The Lull is a slightly firmer all-foam bed that comes with a generous sleep trial. 

What’s the Firmness Of the Lull & Puffy Mattresses? 

At Mattress Nerd, we measure firmness on a 1–10 firmness scale. One is cotton soft, while 10 is as firm as sleeping directly on the floor. Most mattresses fall between 4/10 and 8/10. The Puffy’s firmness level is 6/10 and the Lull’s is 7/10. As such, these are both medium-firm mattresses, which is a firmness that works well for the average sleeper. 

What Do the Lull & Puffy Mattresses Feel Like?

Both the Puffy and Lull provide outstanding motion isolation, which means they’re good mattresses for couples who want better sleep. While both excel in this category, the Puffy slightly outperforms the Lull, thanks to two layers of motion-absorbing memory foam compared to the Lull’s single layer. 

What’s It Like to Sleep On the Lull & Puffy Mattresses?

The Puffy’s thick memory foam layers cushion pressure points and deliver conforming support. The feel works well for lightweight or average-weight side and back sleepers. If you weigh more, you may find yourself sinking too far into the mattress, regardless of your sleeping position. The Lull’s top layer is noticeably firmer, which works best for lightweight stomach sleepers and average-weight back and side sleepers.  

The Lull vs. Puffy Mattresses By Body Type

Lull Performance By Body Type & Sleeping Position:

Body Type:	BACK SLEEPERS	STOMACH SLEEPERS	SIDE SLEEPERS
Lightweight (< 130 lbs):	5	3	3
Average-weight (130–230 lbs):	5	3	4
Heavyweight (> 230 lbs):	3	2	4

Puffy Performance By Body Type & Sleeping Position:

Body Type:	BACK SLEEPERS	STOMACH SLEEPERS	SIDE SLEEPERS
Lightweight (< 130 lbs):	4	3	5
Average-weight (130–230 lbs):	3	3	4
Heavyweight (> 230 lbs):	2	2	3

1 = Very poor, 2 = Not good, 3 = Fair, 4 = Good, 5 = Excellent

Average-Weight Sleepers (130–230 lbs)

Back sleepers fare well on a lot of all-foam beds especially on the Lull mattress while stomach sleepers will find this mattress doesn’t strain their pressure points. The Lull Mattress may suit side sleepers the best of all strict sleeping positions and average combination sleepers will find this bed pretty easy to move around on. 

Average-weight back sleepers are best supported by the pressure-relieving foams while side sleepers will find the medium-firm Puffy to provide pressure relief and a gentle hug around their hips and shoulders. Average-weight stomach sleeper, the Puffy mattress will likely not be firm enough but combination sleepers will find this bed pretty easy to move around on.

Heavyweight Sleepers (> 230 lbs)

The Lull will evenly distribute the weight across the body and support the lower back to keep the spine aligned for all back sleepers. For stomach, side, and combination sleepers, it offers a good balance of softness and support and provides excellent pressure relief, so you can wake feeling rested and refreshed instead of sore and tight.

If you’re a heavyweight side and back sleeper, you might need a mattress with less “sinking.” However, for stomach sleepers, the Puffy mattress will likely not be firm enough the same as combination sleepers. 

Lightweight Sleepers (< 130 lbs)

The Lull will evenly distribute the weight across the body and support the lower back to keep the spine aligned, which is good for back sleepers. For stomach, side, and combination sleepers, this mattress doesn’t strain their pressure points, but it also may cause some sinkage in the hips due to not enough support to keep the spine aligned.

Lightweight back sleepers are best supported by pressure-relieving foams, while side sleepers will find the medium-firm Puffy to provide pressure relief and a gentle hug around their hips and shoulders. Stomach sleepers will need a firmer, more supportive mattress to prevent their hips from sinking too deep into the foam, combination sleepers who spend the majority of the night on your side, the Puffy should be a good fit for you.

Differences In Mattress Construction 

Lull is made up of three layers of premium memory foam. The Lull mattress has a removable fabric cover made of polyester and rayon that is also breathable so it doesn’t heat up too much while The Puffy is an all-foam mattress with three layers dedicated to providing superior pressure relief and a “cloud-like” sleeping experience.

Lull Mattress Materials	Puffy Mattress Materials
1.5″ of gel memory foam that’s pressure-relieving and temperature-regulating	Layer #1—Cover
1.5″ of contouring transition foam that provides a firmer layer between the softer top and firmer base	Layer #2—Cooling Cloud Foam
7″ foam support layer	Layer #3—Climate-Adaptive Foam
	Layer #4—Support Layer

Cover

The Lull is a three-layer memory foam mattress that’s a touch firmer than your average bed. Along the top is slow-response memory foam that feels firm at first but gradually softens into light contouring. The Puffy utilizes two layers of memory foam on top of the mattress. The first layer is gel memory foam for cooler sleep, and it has a soft feel that readily cradles pressure points.

Comfort Layers

The comfort layer of The Lull is firmer, providing the support and body alignment that sleepers need for all-night comfort while Puffy’s transition layer is responsive polyfoam that counteracts the memory foam “quicksand feel,” so you don’t feel stuck.

Support Layers

The final layer of Lull is a durable base foam that ensures outstanding motion isolation and above-average edge support. At 10” thick, Puffy is an all-foam bed that has average longevity and fits on most bed frames.

Lull vs. Puffy Mattress Performance Ratings & Differences

Temperature

Since the Lull and Puffy are both made predominantly with memory foam, we don’t expect either to be the best mattress for hot sleepers. Because there are no coils to facilitate airflow, there’s minimal breathability. The result is a slow accumulation of body heat over the night. However, both beds have cooling innovations, like gel memory foam, that help with temperature regulation. 

While we don’t recommend either of these beds if your top priority is staying cool, hot sleepers will likely prefer the Lull. Because you don’t sink as deeply into the top layer of the Lull, more of your body heat can escape along the mattress surface.

Motion Transfer

Couples often complain about excess motion transfer coming from their mattress. Some mattress materials—like innerspring coils and latex—allow motion to spread across the bed more easily than others—like foam, which dampens motion at the source. 

Both the Puffy and Lull provide outstanding motion isolation, which means they’re good mattresses for couples who want better sleep. While both excel in this category, the Puffy slightly outperforms the Lull, thanks to two layers of motion-absorbing memory foam compared to the Lull’s single layer. 

Edge Support 

You don’t want to roll off your mattress at night or feel like you have to balance when you sit on the edge in the morning. To ensure you’re secure when sitting or lying along the sides of your bed, you need a mattress with reinforced edges. 

The Puffy and Lull both have sturdy edges, although they both sink in a bit when you sit along the sides of the bed. The Lull is a touch more comfortable for sitting thanks to a firmer top layer.

Pressure Relief

Most soft mattress fans love how plush foams melt pressure away from areas like shoulders and hips. The Puffy has softer, more conforming comfort layers that are better suited than the Lull for side sleepers, especially those with joint pain. The Lull’s modest pressure relief is good for lightweight and average-weight back and stomach sleepers, but not side sleepers.  

Pain Relief 

The Lull provides superior spinal support for most stomach sleepers thanks to a firmer surface. By keeping the hips aligned with the shoulders, the Lull minimizes the potential for lower back pain—although heavyweight stomach sleepers should consider a mattress designed for bigger bodies. The Puffy’s softer surface better contours the spine when side sleeping and is superior for back health in side sleepers. 

Both mattresses do a great job delivering superb spinal alignment for back sleepers. Opt for the Puffy if you want a bit more contouring or the Lull for a feel that’s akin to sleeping “on” the surface of the mattress.

Durability 

The Lull is likely to outlast the Puffy by a year or two, but they both have average durability for memory foam mattresses. Lull’s firmer sleeping surface and thicker, high-density base foam layer creates superior longevity.

Our Final Take

If you need extra pressure relief or love a hugging surface, opt for the Puffy. But if you prefer a firmer mattress where you sleep “on” the surface, we recommend the Lull. Both beds are exceptional for couples and come with risk-free trial periods, although you have over three times longer to try out the Lull. If pricing is important to you, the Lull is slightly lower cost.

Lull & Puffy FAQs

Do you need to rotate a Lull mattress?

No, you should not flip a Lull mattress. The support layer is on the bottom, so if you did flip it, you’d be sleeping on a super-firm surface. If you’re worried about wear, aim to rotate your mattress 180 degrees approximately every six months.

Are Lull mattresses good for heavy people?

Heavier folks (250 lb and up) also might not find enough support on the Lull, because its all-foam construction isn’t exceptionally sturdy. It also doesn’t have great edge support, so larger folks won’t be able to utilize the full surface of the mattress.

What is the lifespan of a Puffy mattress?

Considering its materials and all-foam construction, the Puffy should be a reasonably durable mattress. Its longevity will, of course, depend on how often it is used and how heavy the sleeper is, but it should last for at least 5 to 7 years.
