If you’re in the market for a new mattress, you may have heard of the online mattress revolution. Rather than going to a brick and mortar mattress store to buy a mattress made of traditional materials, you can have a high tech new mattress delivered to your home in an easy to manage box (AKA “bed in a box”). Casper and Purple are two of the biggest players in this space, but what are the differences, and which is right for you? Here’s a deep dive into Casper vs. Purple mattress.

The Casper Mattress vs. The Purple Original Mattress

When considering Casper vs. Purple mattress, it’s important to make an apples-to-apples comparison. Although both companies also offer hybrid models, here we will focus on the original all-foam mattresses.

Let’s look at what these mattresses are made of:

The Casper Original Mattress:

The Casper Original Mattress is 11 inches high. This three-layer mattress features a supportive, durable base made of polyurethane foam, a zoned memory foam middle layer, and a thinner perforated top foam. Here’s how the layers work together:

  • Airscape™ top layer: Breathable perforated foam boosts airflow to keep you cool at night while conforming to your body to relieve pressure.
  • Zoned Support™ middle layer: Divided into three separate ergonomic zones, this layer provides softness under your shoulders and firmer support beneath your hips and waist.
  • Polyurethane foam base: The thick, strong base is designed for both comfort and support.

The Purple Mattress

The original Purple Mattress is 9.25 inches high. The mattress consists of three parts – a high-density foam base, a soft comfort layer, and a Hyper-Elastic Polymer® Purple Grid, all topped with a stretchy and breathable soft knit cover. Here’s a look at the technology:

  • SoftFlex cover: Designed to flex with the Purple Grid, this breathable knit also promotes airflow.
  • 2-inch Purple Grid: Unlike traditional memory foam, the Purple Grid features thousands of open-air channels, promoting a cooler night’s sleep. It won’t collapse under your body heat but flexes effortlessly as you move around.
  • Dual-layer foam middle and base: Soft comfort foam is layered on top of thick, high-density foam designed for support.

What about comfort?

The Casper Original Mattress

Customers on the Casper site and Amazon note that the original mattress feels reasonably soft yet supportive, and several mentioned that it alleviated back and neck pain overnight. Temperature is rarely mentioned in reviews, but a few people note that it doesn’t feel as hot as other types of mattresses. Several reviews mention that it may take a few days to adjust if you previously had a traditional mattress.

The Purple Mattress

In reviews on both the Purple site and Amazon, customers consistently note that the mattress feels cooler than other models. They also mention that it feels soft but provides enough support, so you don’t feel like you’re sinking into the bed. Some say it may take several days to adapt to the new mattress, but those who persevere are generally quite happy with the results.
