The Purple has a slightly unconventional feel to it, so if you want more of a traditional vibe, I’d recommend going with the Casper. Though they have similar medium-firm feels, the Casper offers slightly deeper pressure relief, marking it as a better option for folks with aches and pains.

Even though both mattresses have a similar firmness level, the feel is very different. The Casper offers the traditional foam feel, while the Purple feels bouncier and as if you’re floating. The Casper is designed around its zoned support, which is softer under the shoulders and firmer around the hips.
