Casper vs Lull: Which is Better for You?

Let’s kick things off with a few quick recommendations! The Lull is a memory foam mattress, while the Casper is an all-foam mattress with a more balanced feel. While both brands offer high-quality mattresses, one will likely be better than the other for your specific sleep needs. Take a look below to see who I’d recommend each of these beds to. I’d also encourage you to check out the full Lull mattress review and Casper mattress review for more details.

Who Should Buy the Casper

Casper Mattress
The Casper Original mattress.
  • Combination sleepers should enjoy the responsive feel of the Casper, which makes it easy to change positions at night.
  • Sleepers with back pain might appreciate the Casper’s zoned support system, which is firmer around the lower back to offer extra lumbar support.
  • Hot sleepers will likely prefer the Casper, which sleeps a bit cooler than the Lull.

Who Should Buy the Lull

  • Side sleepers should like the Lull’s plush feel.
  • Memory foam lovers looking for plenty of sinkage and body-contouring should like the Lull.
  • Couples might prefer the Lull, which does a better job of reducing motion transfer than the Casper. This means you’re less likely to feel disturbed by a restless partner on this bed.

Casper vs Lull: Similarities and Differences

The Casper and the Lull are both all-foam mattresses, so they do share quite a few similarities. However, they do feel very different! Take a look at the lists below for quick info on the similarities and differences between these two beds. Then read on to explore their differences in greater detail.

Main Similarities

  • The Lull and Casper both offer similar levels of support. While these beds should work well for most average-weight sleepers, heavy people will likely need a more supportive mattress. I’d recommend they check out one of our best mattresses for heavy people.
  • The Lull and Casper are both all-foam bed-in-a-box mattresses. This means they’ll ship compressed to your door, and will need a few hours for expanding and off-gassing before you can sleep on them.
  • Both of these beds are a little too soft for stomach sleepers. These sleepers need a very firm mattress that helps keep their hips lifted in line with their shoulders. One of our best mattresses for stomach sleepers could be a better fit for them.

Main Differences

  • The Casper feels firmer than the Lull.
  • The Casper is responsive, while the Lull offers slow-moving sinkage.
  • The Casper has more edge support than the Lull, which means you’ll be able to sleep closer to the sides of the Casper mattress than you would to the sides of the Lull.

Casper and Lull Mattress Feel Comparison

Next, let’s get into detail on how these babies feel! Keep in mind that feel can vary depending on your height, weight, and preferred sleeping position. For reference, I’m a stomach and side sleeper, around 5’10”, and I weigh about 190lbs. So what’s firm for me might feel soft to you, or vice versa.

The Lull and the Casper on the mattress firmness scale.

Casper

I gave the Casper mattress a 7 out of 10 on the firmness scale, with 1 being super soft and 10 being the firmest mattress on the planet. Per industry standard, a 6.5 out 10 rating indicates medium firmness, so the Casper is a firm mattress.

Casper Back Sleeping
The Casper’s balanced feel might appeal to combination sleepers.

I was pleasantly surprised by how much support the Casper offered. Its zoned support layer offered plenty of lift and firmness around my hips, but a lot of pleasant softness around my shoulders. I also felt more “on top of” than “in” this mattress, which makes me think it could be a great choice for combination sleepers.

Lull

I gave the Lull mattress a 6 out of 10 firmness rating, so it’s just a tad softer than medium-firm. Because its top layer is made of memory foam, the Lull offers a soft, sinking feeling right off the bat.

Lull Mattress Back Sleeping
The Lull mattress offers great sinkage and body-contouring.

That memory foam feel makes the Lull a great option for anyone struggling with joint pain, as it helps alleviate pressure on sensitive joints like the shoulders and hips. The pleasant hug of the Lull is quite different from the responsive feel of the Casper, and is better suited to sleepers who prioritize pressure relief.

Comparing What it’s Like to Sleep on the Casper and the Lull

A mattress will feel different to you depending on your body type and preferred sleep position. So to help you get an even better idea of what these beds feel like, I broke down how they felt in each of the three main sleeping positions.

Casper

Back — The Casper felt great on my back. It offered a great balance of pressure relief and support, and I could feel it lifting my spine into a healthy, neutral alignment.

Side — The Casper felt okay when I was on my side. If you’re someone who alternates between their side and another position at night, this mattress could work for you. But the Casper might feel too firm if you’re a strict side sleeper. Personally, I found this firmness level a little uncomfortable around the pressure points in my hips.

Casper Side Sleeper
The Casper is a little too firm for strict side sleepers.

Stomach — The Casper felt a little too soft when I was on my stomach. I could feel my hips sinking into the bed, throwing off my spinal alignment. This might lead to pain over time, so I’d steer stomach sleepers to a firmer innerspring mattress instead.

Body Weight — The Casper will likely feel a bit firmer to sleepers who are lighter than me, and a bit softer to sleepers who weigh more than I do. In general, I wouldn’t recommend this bed to heavier people (over 250 lbs). Like most all-foam beds, the Casper isn’t quite supportive enough for heavier folks.

Lull

Back — I felt comfortable on my back. The Lull’s layers of foam did a great job filling in my lumbar region for some additional pressure relief. Back sleepers who like a soft feel will probably like this mattress.

Side — I was most comfortable on my side when I was testing out the Lull. This bed did a great job relieving pressure around my shoulders and hips, and I think most side sleepers could feel comfortable on this mattress.

Lull Mattress Side Sleeping
I like the Lull for side sleepers.

Stomach — Like the Casper, the Lull is too soft for stomach sleepers. In general, I don’t recommend memory foam mattresses to stomach sleepers, who can end up with back pain if they sleep on a bed that offers too much sinkage.

Body Weight — Like the Casper, the Lull will likely feel a bit firmer to lighter people and a bit softer to heavier people. In general, I would not recommend this bed to heavy people. I don’t think it will be supportive or durable enough to make them comfortable.

Comparing Casper and Lull Mattress Materials

Next up, let’s break down the construction of each of these all foam beds. Though they use similar bases, these beds use completely different top foams, which is why they have such distinct feels.

Casper

Cover — The Casper mattress has a knit polyester cover that provides a really soft, cozy feel.

Comfort Layer — Next up comes a top layer of proprietary AirScape foam, which is a soft poly foam with a latex-like feel. That means it’s responsive, and helps keep you “on top of” the bed. This already breathable foam has been perforated to allow even more airflow, helping to keep you cool.

Transition Layer — Below the AirScape foam you’ll find a layer of zoned memory foam — it’s firmer at the hips but feels softer at the shoulders, to help prevent putting pressure on your shoulders and neck during sleep. Ths memory foam layer offers great pressure relief, and since it’s below the AirScape foam, it’s less likely to trap body heat and cause overheating.

Base Layer — Below these foam layers you’ll find a high-density poly foam base, which supports the other layers and provides some solid structure.

Lull

Cover — The Lull has a soft, fairly breathable cover that you can hand-wash.

Comfort Layer — Unlike the Casper mattress, the Lull actually has a memory foam top layer that provides plenty of body-contouring. As I mentioned, memory foam can sometimes overheat, but this gel-infused material is designed to dissipate body heat and prevent that issue.

Transition Layer — Below the gel memory foam is a layer of poly foam. This layer has a quicker response to pressure that provides you with some mobility, so you don’t feel “stuck” in this mattress.

Base Layer — The Lull mattress also uses a high-density support foam base, which provides support and durability to the bed and curbs some of the sinkage its top layers offer.

Comparing Casper and Lull Customer Service

I rate every mattress company’s customer service team when I review new models. I give out ratings of Stellar, Great, Satisfactory, or Poor based on my personal experience with each team.

Casper Sleepopolis Customer Service Rating

Stellar: I gave Casper a Stellar rating because I was promptly put in touch with a helpful agent when I used their website’s chat feature. My question was quickly answered in detail.

Lull Sleepopolis Customer Service Rating

Great: I gave Lull a great rating because my question was answered quickly and my rep provided helpful links I could use to find additional information. But, Lull’s chat feature is not accessible on their home page, you’ll need to navigate to their “contact us” form to reach the chat. Most other mattress websites place their chat feature right on the home screen, which makes it a bit easier to find.

Comparing Other Models from Lull and Casper

Casper offers several other mattress models. I’ll describe a few of them below. Lull offers sleep accessories and bedding, but only sells one mattress model (for now).

  • I’d recommend this model for combination sleepers, as it has great bounce.
  • Like the original Casper, the Casper Hybrid has a medium-firm feel.
