Key Similarities

  • The Lull and Purple have a similar thickness and also similar base layers.
  • They also feature similar transition layers.
  • The mattresses are similar in terms of firmness.

Key Differences

  • The Lull is cheaper than the Purple by a noticeable amount.
  • The materials in the comfort layer are very different and this provides the mattresses different feels.
  • The Lull has a balanced foam feel, while the Purple features a unique, responsive gel feel.

Lull Construction

  • The Lull is 10” tall and features a simplified construction with three 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 contours very well to precise curves of the body.
  • Next, is a 1.5” layer of transition, latex-like foam that prevents sleepers from sinking extremely far into the mattress.
  • The final layer is 7” of a base support foam that is pretty standard on the market.

Purple Construction

  • The Purple is 9.5” tall and features two foam layers and a layer of proprietary hyper-elastic polymer.
  • The cover is soft and thin and doesn’t affect the overall feel of the mattress significantly.
  • The first layer is 2” of a Purple Smart Comfort Grid, which is a hyper-elastic polymer with a squishy feeling.
  • Next, there are 3.5” of a Plush Comfort Foam that acts as a transition layer.
  • The base layer is 4” of polyfoam, which is a pretty standard base layer in the industry.

Construction Differences/Notes

  • They both have thin covers that let people interact with the mattress layers quite easily and don’t affect the feel in a significant way.
  • The gel memory foam layer on the Lull is very soft but not thick, so heavier sleepers may press through and feel the firmer support layers.
  • The Purple has a very unique comfort layer that is made of a hyper-elastic polymer and is designed to stay firm until enough pressure is applied, which means it can be both supportive and pressure relieving.
  • The Purple is going to be the more breathable mattress of the two, and the gel grid allows a lot of room for airflow, so people should be sleeping cooler on this mattress.
  • The Purple is also the more durable mattress without question because the gel grid should be longer lasting than the gel memory foam in the Lull.

Firmness And Feel Differences

For me, both the Lull and Purple had a 7/10 firmness.

On my back, I felt well supported on both mattresses. The foam on top of the Lull conforms to the curves of my body and the Purple’s gel grid collapses under my butt but keeps the rest of the body well supported.

On my side, I feel a little bit of pressure on my shoulders and hips when I am on the Lull because the comfort layers are pretty thin. On the Purple, I feel almost no pressure because of the way the gel material works. I think heavier sleepers may feel even more pressure on the Lull as they press through the soft comfort layer and engage the support layers beneath. On my stomach, I do feel properly supported on my both mattresses, so they are both excellent matches.

In terms of feel, the Lull has a balanced foam feel with a bit of that slow-sinking memory foam feel on top. The Purple has a unique, squishy gel feel that is firm, but pressure relieving at the same time.

People can see how the Lull’s firmness and feel is in the video below.

Motion Transfer Differences

Between these two mattresses, the Lull handles motion transfer better than the Purple because of the differences in construction. That top layer is gel memory foam which is usually good at cutting down on motion transfer.

During the tests, I saw less disturbance on the Lull so, between the two, I think it is a better choice for couples who don’t want to be disturbed by their partner’s movements.

Now, watch how Purple performs with motion transfer in the video below.

Edge Support Differences

Also, I think the Lull features better edge support than the Purple for a number of reasons. Sitting near the edge, I feel secure enough to lean over and tie my shoes.

Also, lying down, I did not feel like I was going to roll off 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 two mattresses and how appropriate they are for heavier sleepers:

In terms of firmness, I said the Purple was a 6.5/10 and the Lull was closer to an 8/10.

Joe said both these mattresses were closer to a 7/10. I think the main reason for my different experience is because of how, on the Purple, I activate the gel layer more and it feels softer than it did to Joe. On the Lull, as a heavier person, I press through the soft upper layers and feel the firm layers beneath. So, it feels firmer to me than it did to Joe as a result.

On the Purple, I feel good support on my back, as the top layer collapses under my butt, but the rest of the mattress stays flat. Moving to my side, I feel almost no pressure on my shoulders and hips, and on my stomach, I also feel good overall support.

On the Lull, I get good support and body contouring when I am on my back. On my side, I definitely feel some firmness on my shoulders and hips because the comfort layers are pretty thin. Also, on my stomach, I need some more support and would want a thicker mattress or one with steel coils.

If someone is a heavier back sleeper, either would work for them. If someone is a heavier side or stomach sleeper, they should lean toward the Purple.

I was not surprised by Marten’s experience given his weight. He is a larger person, so he did press through the Lull’s comfort layers and find it to be a firmer mattress. On the Purple, he activated the gel grid more than I did, so he actually found it to be softer.

Who Should Pick Lull:

  • Lighter side sleepers- If someone is under 160 lbs and sleeps on their side, they may want to consider the Lull, because the top layer is very soft and could give them the pressure relief they need. They may be too light to get the full effect of the Purple’s gel grid.
  • You are looking for a more affordable mattress. The Lull is the cheaper option so, if money is real factor, the Lull might be the way to go.

Who Should Pick Purple:

  • Medium-weight or heavy side sleepers- With the Purple, there is less of a chance of bottoming out on the mattress and feeling the support layer. If someone is 160 lbs or above, they should activate that gel grid and get some nice pressure relief on their shoulders and hips.
  • Those who are looking for a long-lasting mattress- The Purple is definitely going to be the more durable of the two mattresses without question. That hyper-elastic polymer gel grid plus the high-density foams beneath it should make this mattress a good long-term investment.

Overall

Both of these quality mattresses could be a good choice, depending on one’s sleep preferences and needs If someone is lighter and wants a more affordable mattress, they should choose the Lull, and if someone is heavier and wants a long-term investment, they should go with the Purple.
