Highlights of Casper vs Purple

The Casper Mattress

Casper mattress in a room

  • Casper has updated their flagship mattress with Zoned Support, designed to cradle your hips and shoulders while keeping your spine in alignment. This means the Casper is one of the best mattresses for side sleepers, stomach sleepers, and back sleepers alike. It also means you won’t wake up with aches and pains because of poor support.
  • The Casper mattress scored an impressive 10/10 in responsiveness. This is an important feature for those who toss and turn a lot at night, as it ensures you won’t feel stuck in one position.
  • If you share the bed with someone else, it is important to look for a mattress that offers proper support all the way to the edge of the bed. The Casper mattress delivers great edge support, scoring an impressive 9.5/10. If you find yourself regularly snoozing at the edge of the bed, you can rest assured that your body will be fully supported.
  • Casper is a company you can feel good about buying from. They donated over 70,000 sleep products to people and animals in need, and they reduce their environmental impact by accepting old sheets, pillows, and bedding for recycling.

The Purple Mattress

  • The Purple mattress is topped with a unique gel-like comfort layer that relieves pressure and keeps the spine in proper alignment, making it one of the best memory foam mattresses. This makes it a great choice for all sleep positions. It also means the Purple mattress has a different feel than your typical memory foam bed.
  • The Purple Grid top layer features thousands of open air channels that allow exceptional breathability and airflow, an important feature for those who tend to run hot throughout the night.
  • Many customers who sleep on a Purple claim that it has put an end to their back pain, thanks to the way the material cradles and supports your body.

Design

The Casper mattress is a universal memory foam bed for the average sleeper. While memory foam has a tendency to trap heat, the Casper mattress is designed with a breathable open-cell foam top layer to encourage airflow. The bed was recently redesigned with Zoned Support, so it cradles your pressure points while keeping your spine in alignment. This is a great feature for all sleeping positions.

The Purple mattress has a unique gel-like top layer that flexes under pressure points while keeping the spine aligned. The Purple Grid material has thousands of air channels to promote airflow, making it a great mattress for those who are concerned about sleeping hot. While the Casper is an all-foam bed, the Purple mattress is a hybrid mattress made of hyper-elastic polymer and foam. This gives Purple a unique feel that many people love.

Pressure Relief

Both the Casper mattress and the Purple mattress scored an 8.5/10 in pressure relief. The Casper was recently redesigned with Zoned Support, which provides firmness and contouring in just the right areas. This is a great feature for back sleepers, stomach sleepers and side sleepers. The Casper also shines when it comes to responsiveness and isolating motion, making it an excellent choice for combo sleepers or people who toss and turn a lot throughout the night.

The brothers who designed the Purple mattress set out to deliver a pressure-relieving bed, and it would appear they have succeeded. The Purple Grid top layer flexes under the hips and shoulders, contouring to your body so that your spine stays in proper alignment.

Motion Transfer

Memory foam is known for its motion isolating properties, and the Casper mattress is no different. Casper scored slightly above the Purple mattress in this category, making it a great option for couples who have issues with motion transfer. Other types of mattresses, such as innerspring, are known for their bounciness and may not work well for those seeking motion isolation.

The Purple bed scored a respectable 7.5/10 in motion transfer, making it a good option for people who share a bed with a partner, a pet, or a child. As the Purple mattress has a gel-like polymer top, it really comes down to which feel you prefer when trying to choose between the Casper and the Purple.

Edge Support

Edge support is another important consideration for couples, as it is likely that one or both partners may find themselves snoozing at the edge of the bed. A good score in this category means you will be properly supported no matter where you sleep on the mattress.  The Casper mattress scored an almost perfect 9.5/10 in this category, while the Purple was close behind at 8.5/10. Both beds should meet your needs quite well in edge support.

Delivery and Returns

When buying an online mattress, it is important to know that you will not get stuck with a mattress you don’t absolutely love. Both online mattress brands offer free shipping within the contiguous United States, as well as free returns. If you are not happy with the mattress within the trial period, simply contact the company to pick up the mattress at no cost to you.

FAQ about the Casper Mattress

  1. How firm is the Casper mattress?

    The Casper is a medium-firm mattress, scoring a 6/10 on the firmness scale. The updated Zoned Support design means the mattress cradles your body’s contours while keeping the spine in proper alignment.

  2. Can I use a slatted foundation for the Casper mattress?

    Yes. A wooden slatted foundation or a platform bed generally offers the best support for the Casper mattress. You can also put your new bed on a solid box spring, a bunkie board on a box spring, an adjustable base, or the floor. The most important factor to consider is that your foundation is not sagging. A poor foundation will not give your new mattress the support it needs to do the best job for you.

  3. How does the Casper sleep trial work?

    Casper offers a 100-night risk-free sleep trial when you purchase a mattress. If you are not satisfied, simply contact the company to start the return process. Casper will pick up the mattress at no cost to you. If possible, they will donate the mattress to a local charity.

FAQ about the Purple Mattress

  1. Can I finance the Purple mattress?

    Yes. Purple offers financing through Affirm. Simply select the appropriate option during the checkout process and you will get a real-time financing decision. 0% APR is available for some customers.

  2. How does the Purple mattress feel?

    The Purple has a unique gel-like comfort layer that flexes under your pressure points in order to keep the spine in proper alignment. Unlike traditional memory foam mattresses, the Purple has a squishier feel.

  3. Is the Purple good for hot sleepers?

    Yes. The Purple mattress scored an 8/10 in the category of cooling. This hybrid bed boasts a Purple Grid top layer with thousands of air channels, allowing air to move away from the body for an active cooling experience.
