Overview Of Lull vs. Casper Review
Here’s a quick run down of the major differences between the beds we’ll be covering in this comparison.
- Price: In comparing the Lull vs Casper, it’s clear that the Lull mattress is cheaper. You’re looking at about a $100-$200 difference after discounts for a queen mattress.
- Top layer: Both beds use memory foam in their constructions, but the Lull mattress uses it as its top layer, while Casper uses it as its secondary comfort layer.
- Zoned support layer: The Casper mattress contains a special zoned support layer that is designed to provide support and pressure relief where you need it most.
Before we get into the heart of our comparison, we want to review some background info about the Casper vs Lull. They are both two notable bed-in-a-box mattress brands on the online market, and are incredibly popular among customers. Neither Lull or Casper are budget beds, but they certainly won’t break the bank either. Each one has their pros and cons, and we’ll dive into each one throughout this comparison.
Lull Mattress Review
We wouldn’t call Lull a memory foam bed because it doesn’t have the viscous, heat-retaining feel of traditional memory foam. Instead, it’s a new-age memory foam bed we think most people will really enjoy.

Lull Construction And Materials
One of the major differences between these two beds is the top layer. When it comes to deciding between Casper vs. Lull, keep in mind that 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. Here’s a layer-by-layer guide to the Lull mattress:

- Top layer: The Lull mattress has a gel-infused cooling memory foam on top that cushions your body and allows air flow for a cooling effect.
- Middle layer: Under the top layer is a sturdier foam that allows your body to rest while offering the support you need to keep your body in alignment.
- Bottom layer: The base was built with durability in mind, and it provides the foundation needed to keep the mattress from sagging over time.
Lull Feel And Firmness
The Lull mattress has a neutral-foam feel, with a tiny bit of memory foam peeking through. This means the comfort layers on the Lull mattress don’t hug your body the way traditional memory foam does.
In regard to firmness, we gave it a medium firmness rating. The Lull mattress offers plenty of therapeutic support, thanks to its firm middle foam layer. The design of the Lull mattress allows your body to relax, while offering the support needed to maintain a healthy alignment.

Casper Original Mattress Review
If you’ve heard of a bed-in-a-box mattress, it’s likely that you’ve heard of Casper. It’s the ultimate neutral feeling online bed, and is designed to be accommodating for a wide range of different sleeper types.

Casper Original Mattress Construction
The original Casper mattress uses a proprietary open-cell foam for its top layer. The bed does contain a layer of memory foam underneath the top layer, but you can’t feel it much. It’s there to provide deep pressure relief for the sleeper. Here’s a layer-by-layer guide to the Casper mattress:

- Top layer: The Casper mattress’ top open-cell foam layer is made from a breathable foam that relieves pressure and circulates the air so you don’t get too hot.
- Middle layer: The middle layer is made of memory foam that is split into three zones — it’s softer under your shoulders and legs and firmer around the hips, waist and lower back.
- Bottom layer: The base was engineered to keep your bed from sinking or sagging and provides the structure and foundation needed for a good night’s sleep.
Casper Feel And Firmness

When it comes to comparing the Casper mattress vs Lull in regard to feel, the Casper has a soft, neutral-foam feel that’s similar to that of Lull, but without the hint of memory foam.
We gave the Casper mattress a medium rating on our soft-to-firm scale. The three zoned areas in the middle layer 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 $1,100 (queen-size) to incorporate this type of design and technology.

Lull vs. Casper Mattress Pricing
If you’re looking for a twin-sized bed, Casper’s prices are lower, but once you get into larger beds, the Lull mattress is typically around $150 less expensive than the Casper mattress.
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. If Lull and Casper are a little out of your price range, check out our list of the Best Cheap Beds.

Mattress Sleeper Type Analysis
As you’ll see below, the Lull and Casper mattresses work for all sleeper types — back, side, stomach and combination. However, we don’t suggest them to all body types.

Body Type Analysis
Considerations For Couples
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.
Motion Isolation
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). 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.
Edge Support
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 good enough to get the job done.
Casper Mattress vs. Lull Review Verdict
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 its 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 because 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.
Company Policies
Part of the reason why bed-in-a-box companies like Lull and Casper have been so successful is due to the extremely friendly customer policies they offer consumers.
- Trial – Casper offers customers a 100-night risk-free home trial period to test out the bed, and Lull offers 365-night risk-free trial. If at any point you decide the bed isn’t right for you, they also offer
scompletely free returns. - Warranty – Casper backs their beds with a 10-year limited warranty, and Lull offers a lifetime warranty. For more details about the warranty, check out their websites.
- Shipping – The mattresses from both companies come with free shipping and arrive compressed in a box. Unbox the mattress and unroll it onto your frame or foundation. It’s recommended you let the mattress fully inflate for about 24-48 hours before using it.

The Review Team
The Casper tends to sleep cooler than the Lull mattress because its top open-cell foam layer is breathable and moves the air so you don’t get too hot while you sleep. However, both beds are temperature neutral and won’t make a big difference in how hot or cold you sleep.
The Lull has more of a memory foam feel than the Casper mattress, so if you’re wary of memory foam, opt for the Casper. The Casper mattress does have a memory foam layer, but the feel of it gets lost under the mattress’ top layer.
The Lull mattress is more affordable than the Casper if you’re purchasing a full, queen, or California king. For these sized beds, Lull mattresses are about $150 cheaper.
