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, meaning 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 firm 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 ax, while offering the support needed to maintain a healthy alignment.

Lull Mattress Sleeper Type Analysis

The Lull mattress works for all sleeper types — back, side and stomach.

Lull Is Best For Lean Sleepers

While we think the Lull mattress will work for all sleeper types, we don’t think it’s best options for heavy people given its all-foam constructions.

Generally speaking, beds that contain coils are preferable for folks who weigh over 250 lb.

Heavy people might think the Lull mattresses feels more like a medium-soft mattress as opposed to the medium rating mentioned in the previous section, which is based on an average sized person.

Other Casper Products

Casper Construction And Materials

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 ief 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 ieves 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.

Casper Mattress Sleeper Type Analysis

Every type of sleepers will be just fine on this Casper mattress. 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 soft and gentle around their primary pressure points. 

Casper Is Best For Lean Sleepers

The original Casper mattress will work well for all sleeper types, but because it is a foam mattress, it might not be the best choice for heavier folks. Our medium firmness rating is based on an average-sized person.

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.

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.

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 Period

Both companies offers customers a 100-night risk-free home trial period to test out the bed. If, at any point, you decide the bed isn’t right for you, they also offers completely free returns.


Both Lull and Casper back their beds with a 10-year limited warranty. For more details about the warranty, check out their websites.


The mattresses from both companies come with free shipping and arrives 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.


Which mattress sleeps cooler, the Lull or Casper?

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.

Which mattress is better for people wary of memory foam?

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.

Which mattress is more affordable?

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.
