What every best Mattresses has:
- Adequate spinal support.
- Motion isolation.
- Freedom of movement.
Comfortable for most sleepers. Consumer Reports tests the queen-sized Casper mattress and awards it Recommended status in the foam mattress category. It earns ratings of Very Good across the board for support for all types of sleepers, as well as for stabilization, which means it reduces motion transfer. Kevin Purdy, testing the Casper for Wirecutter says this latest version of the Casper "feels softer for side-sleeping than previous versions and yet has more support around the hips and head to make back-sleeping feel better than before."
The Casper earns an overall customer satisfaction rating of 80 percent at Sleep Like the Dead, based on its analysis of 273 customer experiences. Its gets lower ratings for edge support. Unlike some other mattress companies that have reviews available only on their website, there are plenty of reviews for the Casper at Amazon, and most are highly positive. Although reviews for comfort are always subjective, most say the Casper is a very comfortable, supportive mattress; other say it's much too hard or much too soft. Digging into the reviews, we found that poor edge support is one of the most common complaints, so if you tend to sleep close to the edge, or roll around a lot in your sleep, this might not be your best choice. Casper offers a no-fee, 100-night trial and returns are said to be easy and hassle-free -- the company sends a courier to pick the mattress up it you don't want it. If you buy through Amazon, however, the mattress is subject to their 30-day return policy and it must be returned to Amazon.
Costs less than most comparable mattresses. Casper's entire justification for its existence was to make the mattress buying experience less mystifying by offering a high-quality, low-priced mattress that's shipped right to your door. In that, it has succeeded. Consumer Reports names it a Best Buy and, in testing there, the Casper mattress performs as well or better as mattresses costing far more, such as the much-pricier Tempur-Pedic line. The Casper gets a "B" for affordability at Sleep Like the Dead. Shipping is free, and white glove, same day delivery (also free) is available in some areas.
Not much feedback on real-world use. Consumer Reports tests durability by simulating eight years of use, and awards the Casper an Excellent in that category. Sleep Like the Dead gives Casper a "B" for longevity/durability, saying, "Long-term owner data is limited but suggests that the mattress has an above-average lifespan." Since the company has only been around since 2014, it's not possible to evaluate long-term durability in real-world use at this time. However, we did see some complaints on Amazon that the Casper began to sag after just a few months. In addition, Casper has redesigned its mattress twice since its inception, so, technically, the older reviews are for a slightly different mattress. The Casper is covered by a 10-year warranty and the company is reported as responsive to customer complaints.
