Mattress Construction

All three mattresses feature a 3-layer design and all of them use proprietary foams.

Layer breakdown for the Leesa Original (left), Purple (middle) and the Casper Original Foam (right).

Leesa Original Construction

The Leesa Original is a 10-inch mattress that comes with a soft polyester cover. It’s comfort layer is made from their proprietary LSA200 foam, which is very similar to latex. It provides good pressure relief, responsiveness and it is perforated, for improved airflow.

Below it is the memory foam layer that allows you to sink into the mattress. Since it is in the middle layer, the “sinkage” is not too deep, allowing for easier movement and reduces heat trapping. At the base is a thick layer of high density polyfoam for durability and added support. It prevents the mattress from sagging.

Purple Mattress Construction

The Purple mattress is 9.5 inches thick and it comes with a soft polyester-viscose blend cover. The top layer is their proprietary Purple Grid, made from hyper-elastic polymer. This layer is very bouncy, meaning that it is very easy to move, even when laying down. It also gives great pressure relief. The mattress comes with a foam encasement at the edges of the Purple Grid, for edge support.

Below the Purple Grid are two layers of soft and firm polyfoams. The middle layer acts as a transition layer that also gives the sleeper additional support. The base layer is for durability and it supports the whole mattress.

Casper Original Foam Construction

The Casper Original foam mattress is an 11-inch mattress and it is covered with a thin polyester cover that is very soft and breathable. At the comfort layer, you’ll find their proprietary Airspace foam that is very similar to Leesa’s LSA200 foam. It is very responsive and also provides good pressure relief. The foam is perforated as well, to allow air to pass through.

In the middle, Casper uses a memory foam with three ergonomic zones. The upper and lower zones are softer and the middle zone is a bit more firm, so that your spine is properly aligned when you sleep. The bottom layer features a thick polyurethane foam for additional support and durability.

Firmness/Feel

The Leesa Original is the softest of the three mattresses—with a medium rating.

A look at the Leesa Original.

The Leesa Original is a medium mattress that is great for side sleepers or those that frequently change positions while they sleep. The LSA200 and memory foam layers work tremendously well together for comfort. You won’t sink in too much, allowing for easier movement and less heat.

The Purple mattress is a medium firm mattress that is best for back and stomach sleepers. It is very bouncy due to the use of the hyper-elastic polymer in the comfort layer. Pressure relief is also very good even though the mattress won’t let you sink. You will feel more on top of the mattress instead of in the mattress.

Casper’s firmness is somewhere in the middle of the Leesa Original and the Purple mattress. As such, it is great for all types of sleepers, although back and stomach sleepers will have a much better time with it, as it is a bit on the firm side. You won’t sink too much with this mattress as well, due to the memory foam being in the middle layer.

Performance

All three mattresses are very similar when it comes to performance

Closer look at the Purple mattress.

So far, all three mattresses are very similar, especially when it comes to their firmness levels. In this section, we’ll take a look at how they perform in different areas, so that you can have an easier time deciding which one will better suit your preferences.

Motion Isolation

Since all three mattresses are made with foam, motion isolation is very good for all of them. However, if we had to rank them, it’s a tie between Leesa and Casper as far as which one offers the best. The Purple mattress is still good, however, it is not as good as the other two.

Cooling

When it comes to sleeping cool, the Purple mattress comes out ahead. The Purple Grid of the Purple mattress is great for airflow. Also, the lack of memory foam in the mattress reduces heat trapping issues. As for the other two mattresses, they also do a good job when it comes to cooling. It’s just that when compared to the Purple mattress, they fall short.

Responsiveness

For responsiveness or bounce, all three perform very well. However, the Purple mattress has the slight edge due to its hyper-elastic polymer material.

Off-Gassing

Since all of these will come delivered in a box or a bag, expect some chemical smell when you open them. The smell is not dangerous, just a minor inconvenience, and it will be gone in a few days.

Warranty and Other Considerations

Leesa, Purple and Casper offer 10-year warranties for their mattresses.

For warranty, Leesa, Casper and Purple all offer the industry standard of 10 years. All three companies also offer a sleep trial of 100 nights, from the day you receive the mattress. Since it takes a bit of time for your body to adjust to a new mattress, Leesa encourages you to try the mattress for at least 30 days before initiating a return and Purple recommends at least 21 days. If you’re still not satisfied, you can contact their customer service and they will instruct you on what to do.

As for pricing, the cheapest of the three is the Leesa Original, with the Casper not too far off. The Purple mattress is the more expensive option but the price difference between all three is not too wide.

All mattresses are made with CertiPUR-US certified foams, meaning that they are safe to use. It also means that the materials went through several tests to make sure that they are up to standards. Shipping is free for all three mattresses.

Verdict

If you are on a budget, the Leesa Original is the best choice. The Casper is great for people that frequently change positions while sleeping and the Purple mattress is recommended for people that sleep hot.

If budget is the most important factor, the Leesa Original is the best option as it is the least expensive among the three. It is also the softest so it’s best for people that primarily sleep on their sides.

If you don’t particularly like the sinking sensation that comes with memory foam but you still want a mattress that provides great pressure relief, the Purple mattress should be on your list. It’s a very bouncy mattress that’s also great when it comes to temperature regulation due to how it is designed.

The Casper Original Foam mattress is the most balanced when it comes to pricing and performance. It’s great for people that change positions frequently while they sleep. Pricing is a bit higher than the Leesa mattress, but lower than the Purple mattress. It has very good cooling, motion isolation and responsiveness.
