Our Verdict
The Casper Original wins for most sleepers thanks to its better motion isolation, lower price, and more traditional comfort feel. However, the Purple Original is the better choice if you sleep hot or prefer a more unique, responsive feel.
Overview
The Casper Original and Purple Original are two of the most popular bed-in-a-box mattresses in America. Both target the mid-range market, but they take very different approaches to comfort. Casper uses a traditional three-layer foam construction, while Purple features its distinctive GelFlex Grid technology.
We tested both mattresses side-by-side for 8 weeks to help you decide which one is the better fit.
Construction Differences
The Casper Original is an all-foam mattress with three layers: a perforated AirScape top foam, a memory foam transition layer, and a high-density polyfoam base. It’s a straightforward, proven approach.
The Purple Original takes a more unconventional route with its hyper-elastic polymer GelFlex Grid as the top comfort layer. This grid-like structure collapses under pressure points (like shoulders and hips) while remaining firm under lighter areas (like your waist).
Comfort Comparison
Both mattresses rate around a 6/10 on the firmness scale (medium), but they feel very different. The Casper provides a classic memory foam “hug” that slowly conforms to your body. The Purple feels more responsive and buoyant, with the grid snapping back quickly when you move.
Your preference comes down to whether you like the slow-adapting embrace of foam (Casper) or the more responsive, floating feel of the grid (Purple).
Temperature
Purple wins this category clearly. The open grid structure of the GelFlex Grid allows air to flow freely, keeping the sleep surface noticeably cooler than the Casper. If you’re a hot sleeper, this is a significant advantage.
Motion Isolation
Casper takes this round. The all-foam construction absorbs movement much more effectively than Purple’s responsive grid. If your partner tosses and turns at night, the Casper will give you less disruption.
The Bottom Line
Choose the Casper Original if you’re a side sleeper who wants classic pressure relief, sleep with a restless partner, or want to save $200.
Choose the Purple Original if you sleep hot, prefer a bouncy/responsive feel, or want stronger edge support.
