Casper vs Lull Mattress: Construction

Foam is the name of the game for both Casper and Lull

Four foam layers make up every Casper mattress. This makes it a hybrid foam mattress. The layers include a 1.5” layer of responsive poly foam, 1.5” of memory foam, a 1.5” layer of poly foam, and the foundation which is 5” of support foam. These layers work together to ensure that your mattress is supportive, cool, and comfortable no matter your physical needs or sleep position.

Each Lull mattress is made of three layers of memory foam. The first layer is 1.5” of gel-infused memory foam. The next layer adds 1.5” and though it’s polyfoam it gives you the feel and bounce that latex might. Finally, your foundational support layer is 7” of high-density poly foam. The result is a medium-firm mattress that offers added support, the reduction of aches and pains, and a cool sleep space.


Lull vs Casper Mattress: Firmness

Casper is firm, but Lull is firmer

Lull is considered to be medium-firm as far as mattress firmness goes. If we had to pick a number to put to the firmness I would say it’s a 7.5 out of 10. This means that while it is the firmer of the two mattresses, it still has a little softness to it. The Lull was designed this way to ensure that whether you sleep on your stomach or your back, you’re going to be comfortable.

While Lull works for all sleep positions, due to the firmness, side sleepers might feel more at home on a Casper, which is just slightly softer. On the ten-scale, Casper is somewhere between a 6.5 and a 7. Casper will cradle your body while still offering the firmness that many require to sleep comfortably.

Lull vs Casper Mattress: Motion Transfer

Motion isolation leads to a tie with both brands offering quality motion isolation

Motion transfer isn’t going to be a problem where Lull is concerned. This mattress is made of multiple foam layers and works to ease your aches and pains. This means that you might notice that you move less while sleeping, because your body is more comfortable. That said, if you do move the high-quality foams used will ensure that no one ends up feeling those movements or waking up as a result of them.

Casper is a foam hybrid mattress. That means that it is made up of a variety of foams, not just one. Foam is excellent at isolating motion. So, if you find you toss and turn, you won’t have to worry about disturbing the one next to you. Casper’s motion transfer is minimal, if you can feel any at all. This makes the mattress a good choice for couple’s because no one will end up waking anyone up in the middle of the night.

Luxury mattresses at a fair price though Lull will save you the most

Casper created a mattress that could reach the most people possible. To do that they wanted to ensure that it was affordable for everyone. The King and California King are under $1,200.

Casper vs Lull Mattress: Trials and Warranty

Both Casper and Lull provide industry standard trials and warranties

Most bed-in-a-box mattress companies offer risk-free trials. This gives you the ability to try the mattress and really get to see if sleeping on it is right for your needs. Where Casper is concerned, you’ll receive the fairly standard 100-night risk-free trial. If you’re unhappy with the mattress and want to send it back, you’ll get a full refund during this window. Most people won’t need to use this trial, but if you do, it’s there for you. Keeping the mattress ensures that you’re protected by a limited 10-year warranty.

Lull offers a fairly similar deal for both the risk-free trial and the warranty. Just call Lull during the first 100 days of ownership, if you want to return the mattress. They will schedule a pickup of your mattress, give you a full refund, and you’ll be free to find something right for you. A 10-year limited warranty is available if you keep the mattress.
