Key Similarities:

  • Both the Lull and Casper mattresses excel in pressure relief and spine alignment, making them great choices for side and back sleepers.
  • The Casper and the Lull are both memory foam beds with a medium-firmness level. This means they both have a similar feel of soft and squishy, but still firm enough to prevent you from completely sinking into the mattress.
  • Both mattresses work for couples phenomenally well; the memory foam design lends both beds to excel at limiting motion transfer.

Key Differences:

  • The Lull is slightly less expensive than the Casper, but both beds hover around $1,000 for a Queen, making them affordable choices.
  • The Casper is better for combination sleepers, because it’s so responsive (more on this later). 
  • The Lull is a gel memory foam bed, while the Casper is an all-foam bed. You may think the gel infusion makes the Lull suited for hot sleepers, but because it’s still a memory foam mattress, it still doesn’t keep you as cool as a hybrid or innerspring bed would.

Casper Mattress Review Highlights

  • This is the original Casper mattress and their most popular model—for good reason.
  • The Casper is one of the best known foam beds and is recognized for truly appealing to average sleepers for its universal firmness level and soft foam layers. 
  • This mattress has received a perfect responsiveness score, so it is superb at adjusting to your movements while you sleep and aligning with your sleeping position
  • The Casper is a great option for combination sleepers and has also clocked the needs of side sleepers
  • This mattress company is always updating the Casper’s design and developing new and dynamic technology. They recently introduced Zoned Support, a new foam system that delivers contouring to pressure points.
  • If you’re a fan of Casper or just interested in their other models, check out the Casper Wave Hybrid and the Casper Nova Hybrid.

Lull Mattress Review Highlights

Compare the Layers Inside

Now it’s time to take a peek inside each Casper mattress and Lull mattress to discover what makes them unique in order to help you get a good night’s sleep. But first, let’s take a look at how their respective constructions compare to one another.

The Casper has three layers of memory foam designed for optimal support and pressure relief. An aerated top layer of foam feels soft to the touch and enhances breathability. The real star of the show here is Casper’s zoned support layer; it consists of not 1, not 2, but 3 ergonomic zones designed for targeted support. This is the reason Casper’s spine alignment score is so high! This layer also assists in even weight distribution and pressure point relief. A support layer of durable foam completes the mattress, and ensures overall support.

Contrarily, the Lull has 5 layers, consisting of three memory foam and 2 covers. The Lull’s dense foam layers work in tandem to provide therapeutic support and relief, similar to the Casper. The main difference in their construction is the inclusion of gel in the Lull. The Lull’s first foam layer is injected with gel for added cooling. 

Because both the Lull and the Casper are foam beds with medium-firmness, they feel quite similar. The result is two universal mattresses that work with a variety of sleep positions and body types. If you enjoy a balanced feel on your mattress that provides soft comfort and support, you can’t go wrong with either choice.

Inside Casper Original

Inside the Casper Mattress

Comprised of three memory foam blend layers, the Casper mattress seeks to deliver relief to pressure points, offer a bouncy surface that also promotes body contouring, and eliminate heat retention.

  • Top Layer: Made of 1.5” of open cell foam, this memory foam layer offers body contouring.
  • Zoned Support Layer: This transition layer is firmer and is made up of another 1.5” of memory foam that offers support and helps maintain proper spine alignment. 
  • Base Layer: The bottom layer of the mattress offers 5” of durable support foam.

Inside the Lull Mattress

Recognized industry wide as a mattress that is medium firm on the firmness scale, the Lull is composed of three premium memory foam layers including gel memory foam that lets you sleep cooler. 

  • Breathable Top Cover: Hand-crafted and designed for airflow, this cover is soft to the touch and serves as a protectant for the rest of the layers.
  • Comfort Layer: Made up of gel memory foam, this layer promotes relief of pressure points and seeks to minimize heat retention
  • Middle Layer: This next layer offers full body support and serves as a comfort layer in the bed. 
  • Base Layer: The bottom layer is made of polyurethane foam, which makes the mattress extra durable while also delivering motion isolation. Plus, this polyfoam base layer is key in preventing sinkage and keeping the mattress from sagging in the long term.
  • Premium Mattress Cover: The cover of the mattress is one that you can remove for cleaning purposes. It is made from a rayon and polyester blend.

Spine Alignment

Spine alignment is crucial no matter the position you sleep in. That’s because it’s a test of how well a mattress maintains a straight spine. Good spine alignment can not only prevent back pain, but promote a healthy posture.

The Casper and the Lull both earned scores of 9.5 on spine alignment, which means they’re phenomenal choices for anyone looking to relieve back pain. Side, stomach, and back sleepers would also appreciate these mattress’s outstanding spine alignment.

Trial Period

Trial period demonstrates how long you can try out the mattress before fully committing. Both the Casper and the Lull received high scores for this factor, because they both give 100 days to try out the mattress.

Edge Support

Edge support measures how secure a mattress’s borders are, so if you happen to get pushed by your partner to the edge of the bed, or you tie your shoes there each morning, you can do so without falling off, or experiencing any dipping or sinking.

Both the Lull and Casper performed well on edge support. They each received near-perfect scores.

Responsiveness

Responsiveness details how much a mattress adapts to your movements and supports your body in various sleep positions.

The Casper earned a perfect score in this category, so combination sleepers– perk up! This means it’s super easy to switch positions on the Casper, and with the Zoned Support layer, you’ll feel comfortable no matter the position you land in. The Lull came up short in this category, only earning an 8 out of 10, which isn’t too shabby, but certainly doesn’t compare to Casper’s perfect score.

Verdict: Which Is the Best Mattress?

When comparing the Lull vs. Casper mattresses Casper beats out Lull with a score of 9.1/10 compared to 8.9/10. However, both mattresses check in with very similar price points and are widely recognized as two affordable mattresses

Casper earns top marks for their shipping, trial period, and warranty, which is identical to the Lull mattress. When it comes to edge support and responsiveness, Casper definitely beats out Lull. However, if you sleep with a partner and are seeking to achieve motion isolation, Lull is the choice for you.

Both the Casper mattress and the Lull mattress have great reputations and appeal to the needs of the average sleeper who is in search of a memory foam mattress and a good night’s rest.
