Memory foam mattresses can offer uniquely soft comfort not found on other types of mattresses, but not all memory foam mattresses are the same. If someone is choosing between two all-foam mattresses such as the Lull and Puffy, they need to look beyond the memory foam to find out which will be the perfect fit.

This comparison will go over the construction of both mattresses and describe the main similarities and differences between the two.

Key Similarities

  • They are both popular mattresses that have similar customer service terms.
  • They are similar in terms of firmness, and they both have gel memory foam on top and have similar base layers.

Key Differences

  • The Lull is more affordable than the Puffy, and it is also firmer overall.
  • The Puffy has a thicker layer of gel memory foam and thicker comfort layers.
  • The Lull has a balanced foam feel, while the Puffy has a classic memory foam feel.

Lull Construction

  • The Lull is 10” tall and features three separate foam layers.
  • The cover is thin and soft and doesn’t affect the overall feel of the mattress too much.
  • The first layer is 1.5” of a gel memory foam, which provides pressure relief and contouring to the mattress.
  • Next is a 1.5” layer of transition, latex-like foam, which gives the mattress bounce and prevents sleepers from sinking too far into the mattress.
  • The final layer is 7” of a base support foam, which is pretty standard for a bed-in-a-box mattress.

Puffy Construction

  • The Puffy is 10″ tall and is comprised of two foam layers.
  • The cover is thin and also doesn’t affect the feel of the mattress too much overall.
  • The comfort layer is 4” of a gel memory foam, which provides softness, pressure relief, and body contouring.
  • The base layer is 6” of polyfoam and is pretty standard for a bed-in-a-box mattress.

Construction Differences/Notes

  • The Puffy has a thicker layer of gel memory foam on top, and because of this, it will have more of that classic memory foam feel. Sleepers will sink into the mattress more with the Puffy and sleep more on top of the mattress with the Lull.
  • The thickness of their memory foam layers also makes them better choices for different types of sleepers, respectively. The thinner memory foam layer on the Lull means it should be a better choice for back and stomach sleepers. The thick layer on the Puffy could make it a better fit for side sleepers.
  • Both mattresses should be about equal in terms of durability and breathability, with the Lull having perhaps a slight edge.

Firmness/Feel Differences

In terms of firmness, I thought the Lull was a 7/10 and the Puffy was a 6.5/10. Note that heavier people might have a different experience, because they may press through the foam layers more than I do and engage the firm support layers in each mattress.

Here’s how it felt while sleeping on the Lull mattress:

  • While back sleeping, I feel great overall. My hips sink in just the right amount, and the foam conforms to the shape of my body.
  • On my side, I am feeling some firmness on my shoulders and hips, and I am definitely engaging the firm transition layer.
  • When I am on my stomach, I feel very well supported and in proper alignment.

This is how it felt on the Puffy:

  • I feel decent support when I am on my back, but I would say I feel better support on the Lull mattress.
  • I feel better when side sleeping on the Puffy. I sink into that soft comfort layer and feel little pressure on my shoulders and hips.
  • I do need more support when I am lying on my stomach and would prefer something a little firmer overall.

The Lull has a balanced foam feel with a bit of bounce and feels more like I am sleeping on top of the mattress, and I have no trouble moving around. The Puffy has a classic memory foam feel where I sink and sleep in the mattress rather than on top. There is little bounce and it isn’t as easy to move around on this mattress and reposition.

Motion Transfer Differences

If someone sleeps with a partner, they should consider how well their mattress handles motion transfer. Since memory foam mattresses are often the best at isolating motion, I expected both the Lull and Puffy to perform well during these tests.

On both mattresses, I saw little disturbance, and when Marten moved around on the other side of each mattress, I did not feel his movements. The Lull and Puffy could be good mattresses for couples who don’t want to be disturbed by their partner’s movements.

See how the Lull cuts down on motion transfer in the video below.

Edge Support Differences

Between these two mattresses, the Lull features better edge support. It is firmer, so when I am sitting near the edge of the mattress, I feel more secure. When I am lying down near the edge of the mattress, I feel less like I am going to roll off or be ejected from the mattress.

Marten’s Take

Marten is a staff writer for us and has a much different body type: He is 6’7″ and weighs about 230 lb; I am 5’9″ and 160 lb. Here is what he thought about these mattresses and how appropriate they are for heavier sleepers:

In terms of firmness, the Lull was an 8/10 and the Puffy was a 7.5 or 8/10. The main reason that my experience was so different from Joe’s has to do with weight.

I press through the soft upper layers on both mattresses and hit their support layers. Because of that, the mattresses feel firmer to me than they do to Joe.

On the Lull, I feel well supported when I am on my back, and my hips sink in, but not too far. Also, the top layer of foam presses into the lumbar area. When I’m on my side, I do press through the mattress, and I feel some pressure on my shoulders and hips. When I’m on my stomach, I need more support and am definitely bowing in at the hips and getting out of alignment.

On the Puffy, I feel decent support, but not as much as I feel on the Lull. When I’m on my side, I’m pressing through the mattress and feeling more firmness than I felt on the Lull. On my stomach, I also need more overall support and probably something a little firmer overall.

Overall, both these mattresses could be a good fit for someone of Joe’s size. However, unless someone is a back sleeper, heavier people might want to look elsewhere.

Being a larger person, Marten pressed deep into these mattresses. These are both all-foam, and not the best mattresses for heavy peopleThey may want to consider a hybrid or innerspring mattress. This will ensure people don’t bottom out and press into the firm support layers.

Who Should Pick Lull…

  • Back or stomach sleepers- Between the two mattresses, the Lull is the firmer and more supportive mattress. If someone sleeps on their back or stomach, their hips shouldn’t sink in too far and they should feel properly supported.
  • Those who want a firmer mattress- The Lull is definitely the firmer of the two mattresses. If someone has had success with firmer-than-average mattresses, this should be the right choice.
  • People who prefer a balanced foam feel- If someone likes a foam feel, but doesn’t want to sink in too far, the Lull should work for them. They will sleep on top of the mattress instead of “in” it.

Who Should Pick Puffy…

  • Those who prefer a softer mattress- Most people will agree that the Puffy is the softer of these two mattresses. If people like a little more give in their mattress and want to sink in a bit more, the Puffy should work especially well for them.
  • Side sleepers- The Puffy has a thicker comfort layer, and it should relieve pressure better than the Lull does. Light- or medium-weight side sleepers should feel little pressure on their shoulders and hips.
  • Those who like a classic memory foam feel- If people like to slowly sink into their mattress, the Puffy is the way to go. The mattress has that quicksand feel, and people should feel enveloped by the mattress. If people prefer sleeping “in” your mattress (rather that on top of it), the Puffy should be the mattress for them.


If consumers keep this information in mind, it should be easy to choose between the Lull and Puffy mattresses, because the differences are quite clear.

The Lull is most likely a better bet for back and stomach sleepers who like a balanced foam feel, while side sleepers who prefer the slow, sinking feeling of memory foam should consider the Puffy.
