Construction Differences/Notes

  • They both have thin covers that let you interact with the mattress layers quite easily.
  • The gel memory foam layer on the Lull is very soft but not thick. Heavier sleepers may press through and feel the firmer support layers.
  • The Purple has a very unique comfort layer. It is made of a hyper-elastic polymer. It is designed to stay firm until enough pressure is applied. This means it can be both supportive and pressure relieving.
  • The Purple is going to be the more breathable mattress. The gel grid allows a lot of room for airflow, so you should be sleeping cooler on this mattress.
  • The Purple is also the more durable mattress. 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 my body supported.

On my side, I feel a little bit of pressure on my shoulders and hips when I am on the Lull. On the Purple, I feel almost no pressure. 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.

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.

Motion Transfer Differences

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

During my tests, I saw less disturbance on the Lull so, between the two, I think it is a better choice for couples.

See how well Lull deals with motion transfer in this video.

Now, watch how Purple performs. The gel grid is great with pressure relief, but not the best with cutting down on motion transfer.

Edge Support Differences

Also, I think the Lull features better edge support than the Purple. 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. He has a much different body type than me: 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:

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

On the Purple, I feel good support on my back. 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. On my stomach, I also feel good overall support.

On the Lull, I get good support when I am on my back. On my side, I definitely feel some firmness on my shoulders and hips. Also, on my stomach, I need some more support.

If you’re a heavier back sleeper, either would work for you. If you’re a heavier side or stomach sleeper, I would lean toward the Purple.

I was not surprised by Marten’s experience. 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.

Pick Lull If:

  • You are a lighter side sleeper. If you are under 160 lbs and sleep on your side, you may want to consider the Lull. The top layer is very soft and could give you the pressure relief you need. You 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.

Pick Purple If:

  • You are a medium-weight or heavy side sleeper. With the Purple, you have less chance of bottoming out on the mattress. If you are 160 lbs or above, you should activate that gel grid and get some nice pressure relief.
  • You are looking for a long-lasting mattress. The Purple is definitely going to be the more durable of the two mattresses. That hyper-elastic polymer gel grid plus the high-density foams beneath it should make this mattress a good long-term investment.

I think both these quality mattresses could be a good choice, depending on your sleep preferences. If you are lighter and want a more affordable mattress, I would choose the Lull. If you are heavier and want a long-term investment, I would go with the Purple. Please leave any specific comments or questions about the Lull or the Nectar in the comment section below.
