|The Lull mattress is a 10" all-foam bed-in-a-box that has a soft, neutral-foam feel and accommodates all types of sleepers.|
|Casper is one of the most popular bed-in-a-box mattresses on the internet. The bed has a soft, neutral-foam feel and contains a unique Zoned Support Layer in its construction.|
We realize reading about mattresses can be a snooze (pun intended), so to keep you on your toes, here are the primary differences between these bed-in-a-box mattresses.
Really, those are the three major points of differentiation between Casper and Lull. As you will find out below, they actually have quite a few similarities. In all honesty, this was one of the more difficult comparisons for us to complete.

One of the major differences between these two beds comes down to the top layer. The Casper mattress uses a proprietary open-cell foam for its top layer, while the Lull mattress uses 1.5″ layer of memory foam. As such, we think the Lull mattress has a little more of a memory foam feel to it than Casper. It’s not an overwhelming memory foam feel, but nevertheless you can distinctly tell the top layer is in fact comprised of memory foam.
However, with that said, we ultimately categorize the Lull mattress as having a neutral-foam feel. Like the top layers on the Casper mattress, the comfort layers on the Lull mattress don’t really conform or hug your body the way traditional memory foam does, which is why we use the term “neutral” to describe the feel.
Overall, we think both mattresses are very comfortable. We’ve found that most people, regardless of their material preferences, find a neutral-foam feel to be very accommodating. If you want more of a traditional memory foam feel, though, be sure to check out our list of the Best Memory Foam Mattresses.
This is the biggest advantage the Lull mattress has to offer. It’s just more affordable than the Casper mattress, plain and simple. For example, a queen size Lull mattress has a MSRP of $950, while a queen size Casper mattress goes for around $1,100.
Those are just the MSRP prices though. Both companies regularly offer discounts and coupon codes, but it seems like Lull is a little more aggressive. Casper typically only takes $50-$100 off, while Lull typically takes $100-$150 off.

Just to be clear, we are primarily referring to the Original Casper mattress in this comparison. The company offers two additional foam models and two hybrid models, as well. There’s the Casper Wave, which is the company’s more premium option. The Wave has a very unique construction and is a little thicker than the Original Casper mattress. Then there’s the Casper Element, which is the company’s entry-level model. The Element is thinner than the Original Casper mattress, but it’s also quite a bit more affordable.
Then there’s the Casper Hybrid and Wave Hybrid, which have similar constructions as their foam counterparts, but with an additional layer containing coils. You can see the hybrid models on Casper.com.
With that out of the way, let’s dig into some of the important details pertaining to the original Casper mattress.
As we mentioned above, the original Casper mattress uses a proprietary open-cell foam for its top layer. The bed does contain a layer memory foam underneath the top layer, but it gets drowned out somewhat. You really can’t feel it all that much. It’s more so there to provide deep pressure relief for the sleeper. Overall, we think the Casper mattress has a soft, neutral-foam feel similar to that of Lull, but without the hint of memory foam.

One unique aspect about the Casper mattress is its Zoned Support layer, which is also the layer of memory foam. What’s neat about this layer is that it’s actually split into thirds. The top and bottom portions are slightly softer to provide more pressure relief under your head, shoulders, and legs, and the middle portion is slightly firmer to provide more support under your lower back and trunk.
Casper states this split foam design is there to provide more comfort where you need it and keep your spine properly aligned in all sleeping positions. Out of all the beds we’ve tested, the Original Casper is the only mattress under $1,000 (queen size) to incorporate this type of design and technology. If you like the sound of a firm/soft split design, you may also be interested in our reviews of the Casper Wave and Brooklyn Bedding Zoned mattresses.
As you read above, there’s really only a couple meaningful differences between these two beds. Here’s the ways in which they are similar.
We think both mattresses land around a medium on our soft-to-firm scale. Neither Casper or Lull are too soft or too firm. Rather, we found both mattresses strike a nice balance between comfort and support.
As such, we think all types of sleepers will be just fine on these beds. Back and stomach sleepers will find that the beds provide a good amount of support and side sleepers will find the top layers on both beds to be very soft and gentle around their primary pressure points. Plus, the other nice thing is that you don’t get any sort of that stuck-in-the-mud feeling that is common among beds that contain memory foam. This means combo sleepers will find it very easy to rotate between positions on both mattresses.
While we think both Lull and the original Casper mattress will work for all sleeper types, we don’t think they are the best options for heavy people given their all-foam constructions. Generally speaking, beds that contain coils are preferable for folks who weigh over 250 lb. That’s because coils are more durable and also provide more support compared to the dense poly foams that all-foam beds (like Casper and Lull) use for their foundations.
As of early 2019, Casper released two hybrid models (beds containing both foam and coils) called Casper Hybrid and Wave Hybrid, which we recommend heavy-set individuals.
Weight has an affect on how you perceive a mattress to feel. Heavier folks tend to sink further into a mattress compared to smaller sized individuals since they exert more force onto the surface. As a result, large individuals generally think most mattresses feel quite soft. Given this, heavy people might think the original Casper and Lull mattresses feel more like a medium-soft as opposed to the medium rating mentioned in the previous section, which is based on an average sized person.
After testing each mattress, we think both beds sleep temperature neutral. The mattresses do not use any special textiles or materials to actively cool you down throughout the night, but our testing team didn’t feel like they warmed up either. Given this, we think external factors will ultimately play more of role in determining your sleeping temperature as opposed to the bed itself. For example, how low you set your thermostat, the type of pajamas your wear to bed, and what kind of sheets/blanket/comforter combination you use will have more of an effect on how warm or cool you sleep.

If you share a bed with a partner, two important factors to consider are edge support and motion isolation. Luckily, both Lull and Casper perform well in these departments. First, both beds deaden movement extremely well, which isn’t a big surprise given all-foam beds generally excel here (there’s no bounce from coils). Motion isolation is important for couples in which one partner tends to toss and turn or get up a lot throughout the night. Beds that deaden movement well like Casper and Lull mean you’ll feel less of your partner’s movements, which should hopefully lead to a more restful night of sleep.
Secondly, both beds also provide fairly solid edge support. As you approach the side of either bed, you still feel properly supported and never as if you’re going to slide right off the edge. We wouldn’t say either bed provides superb edge support (they’re both all-foam beds), but it’s definitely good enough to get the job done. Edge support is important for couples who sleep on a smaller sized mattress, like a full or queen. The better the edge support, the more useful surface area there is for both partners to spread out and get comfortable.
If you made it this far, you hopefully now understand why we said this was one of the harder comparisons for us to complete. The two mattresses are similar in a lot of ways. If you’re still struggling with the decision between Casper and Lull, in our eyes, it really comes down to the following two decision points.
Price — If you’re on a tight budget, Lull is the way to go. Not only does Lull price their beds more affordably from a MSRP standpoint, but they also offer larger discounts than Casper.
Memory Foam — If you like memory foam, Lull is the way to go. It has more of a discernible memory foam feel since the bed uses it for its top layer. If you’re not a big fan of memory foam, Casper is the better option as its memory foam layer is sort of drowned out by the proprietary foam top layer.
