Similarities

First, let’s go over some of the similarities between the Lull and Casper mattresses.

Support – Both the Lull and the original Casper mattress are all-foam mattresses, without springs or coils. Casper does also offer hybrid models, and those contain pocketed coils. Both beds have memory foam layers, but they serve totally different functions in each mattress. We’ll talk more about that a bit later.

Packaging – The Lull and the Casper are both bed-in-a-box mattresses that ship compressed into boxes, unlike traditional mattresses. Typically, bed-in-a-box mattresses need a few hours to fully “inflate” after you open them up.

Policies – The two companies have super similar policies, including free shipping, 10-year warranties, and 100-night trial periods.

Next, I’ll spend some time talking about the differences between the Lull and Casper mattresses, specifically how they’re different in their construction, feel and price.

Differences in Mattress Construction

Next up, let’s break down the materials and construction of each of these beds. For more details on mattress construction, you can check out my full reviews of the Lull mattress and original Casper mattress.

Casper

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

Comfort – Next up comes a layer of proprietary AirScape foam, which is an incredibly soft poly foam that will make you feel like you’re sinking into the mattress. This already breathable foam has been perforated to allow even more airflow, helping to keep you cool.

Transition – 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 – 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 – Unlike the Casper mattress, the Lull actually has a memory foam layer on top that provides a contouring, hugging kind of sensation. As I mentioned, memory foam can sometimes overheat, but this gel-infused material is designed to dissipate body heat and prevent that issue.

Lull Mattress

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

Base – The Lull mattress also has a high density poly foam base, providing support and structure.

Casper vs. Lull

Both Casper and Lull are all-foam mattresses that use memory foam in their constructions, but because they use them in different ways, they are going to feel very different.

Casper’s comfort layer will allow you to sink into the mattress without feeling stuck. The top layer made with AirScape foam is both breathable and bouncy. Casper’s zoned support will also help distribute your body weight more evenly on the mattress, helping to prevent any soreness or joint pain.

Lull, on the other hand, has a more traditional memory foam feel. You might feel like you’re sinking into the mattress or getting that hugging, contouring feeling. Lull’s comfort layer is infused with gel to try and combat heat trapping, but it’s not as breathable as the AirScape foam in the Casper.

What Do These Mattresses Feel Like?

How firm or soft a mattress feels is totally subjective! It can vary depending on your height and weight, preferred sleeping position, and all sorts of other considerations. For reference, I’m a stomach and side sleeper, around 5’10” tall, and I weigh about 190lbs. So what’s firm for me might feel soft to you, or vice versa.

Casper

I give the Casper mattress a 7/10 on the firmness scale, with 1 being super soft and 10 being the firmest mattress on the planet. Per industry standard, a 6.5/10 rating means medium firmness, so this is just a touch firmer than that.

I was pleasantly surprised by how much support the Casper offered. The extra support around the hips provided by the zoned memory foam layer prevented me from sinking too far into the mattress. I’d recommend this bed for back sleepers, side sleepers, or back and side combo sleepers.

That said, I don’t think it offers enough support for most strict stomach sleepers like myself. And heavier folks who weigh about 250lbs or more may also want a mattress model with more support.

Lull

I give the Lull mattress a 6/10 firmness rating, so it’s just a tad softer than medium-firm. Because the memory foam layer is on top, it offers that soft, sinking feeling right off the bat, with great pressure relief but a little less support.

The memory foam makes the Lull a great option for side sleepers, as it helps alleviate pressure on sensitive joints like the shoulders and hips. However, strict stomach sleepers may find this mattress just doesn’t offer enough support, as their hips can sink down into the mattress lower than their shoulders.

In my opinion, most back sleepers who prefer a softer feel will be just fine on the Lull, but I don’t love it for stomach sleepers or heavier folks who need more support.

Other Models

Casper does also sell a few other mattress models, which I wanted to do a quick section on here. Specifically, I wanted to talk about their hybrid offerings.

Casper Hybrids

  • The Casper Hybrid contains comfort foams very similar to those found in the original Casper, but with pocketed coils rather than high density poly foam! I’d recommend this model for combination sleepers, as it has great bounce and a medium-firm feel.
  • Then there’s the Casper Nova Hybrid, which has a soft, sinking feel and excellent pressure relief. I like this pick for side sleepers and people who run hot at night.
  • Last but not least there’s the Casper Wave Hybrid, which is a luxury model. It has a higher price tag, but offers plenty of support – ideal for heavier folks and a wide range of sleepers.

Which is Better: Lull vs. Casper

Now that we’ve gone through all sorts of details on each mattress, I can provide my final recommendations on these two models. These are both very good beds, but they have different strengths.

If you suffer from back pain, the Casper could be a great option for you. The zoned support foam really helps bolster support at your hips while relieving pressure on your back, neck, and shoulders, giving you a really comfortable feel.

The Lull is a good pick if you love that traditional memory foam feeling. Because the memory foam layer is right on top, you get that sinking, contoured feel right off the bat thanks to the slow-release properties of the foam. The Casper does also have memory foam, but because the layer comes beneath another foam, you don’t get that same sinking sensation.

Breaking it down a little further, here are my main pros for each model:

Casper Pros

  • I like this model for side sleepers, as the zoned memory foam offers support for the hips and pressure relief around the shoulders.
  • It’s also a great pick for people with back pain, as the combination of poly foam and memory foam provides pressure relief that can help alleviate aches and pains.

Lull Pros

  • Because the memory foam layer is right on top, you get that classic memory foam feel — the layer envelops you and contours around your body, allowing you to sink into the mattress a bit.
  • After the discount is applied the Lull is a bit less expensive than the Casper, so is a more affordable option.
