In this comparison, we’re evaluating the well-known Casper mattress against the veteran-backed Ghostbed design. While both foam mattress share similar shipping options, trial periods and return policies, the construction and custom reviews are what sets them apart. To learn which online mattress is the right choice for you, look through this compilation of in-depth research, industry expert reviews and hard data.
Looking first at the Ghostbed, this mattress is constructed from three different layers. The top is an aerated latex foam that allows for increased airflow and good bounce. After the comfortable top layer comes a gel memory foam. Providing pressure relief and the first level of support, this material is meant for deep compression support but still has a slight give. Rounding out the Ghostbed is a dense support foam layer that acts as a foundation for the entire design. Covering all of these layers is a white polyester top piece and gray poly-blend side panels. Although this color scheme and fabric is common among foam mattresses, the Ghostbed cover is durable, snaps back into place and has a smooth transition from one fabric to the next.
Moving onto the Casper mattress, the first difference in construction is an extra layer of foam. Similar to Ghostbed, the top layer of Casper is a latex foam that gives sleepers instant cooling and comfort. Underneath that is a denser memory foam layer that absorbs pressure and offers support. Since memory foam responds slower to pressure but still compresses under weight, the third layer of Casper is a transitional polyurethane foam that acts as a barrier between sleepers and the final rigid support layer. The cover of Casper also has a white and gray color scheme, with 100% polyester on the top and a poly-blend fabric for the side panels.
A major difference between the Casper and Ghostbed is the thickness of each mattress. Measuring in at 9.5 inches, the Casper has an additional foam layer but falls short of the Ghostbed with a thinner base layer. Measuring in at 11 inches, the Ghostbed mattress opts for thicker layers of foam instead of adding additional thin layers. In both mattresses, the thickness plays an important part in the overall firmness. Look through our evaluation on the firmness of each below for a better look at how each feels.
When it come to weight, the Casper and Ghostbed are incredibly similar. Remember when selecting a mattress that weight is one of the last factors to consider, unless you plan to move or transfer the mattress often. Firmness is much more important than weight in regards to durability and comfort level. For the slight differences, scan our chart below for exact weights according to size.
For both designs, durability has not been a major issue among customers. The mattress review website Sleep Like the Dead rated the designs as “good”, which means they are likely to last more than seven years. What does matter here is the difference in warranties. Casper offers a 10-year warranty, while Ghostbed doubles the guarantee with a 20-year warranty.
Sleeping position is one of the most important factors to consider when searching for the ideal mattress. After looking through customer testimonials and review websites, we discovered average ratings for back, side, and stomach sleeping positions. For the rankings below, know that small sleepers are under 120 pounds, average sleepers are 130-230 pounds, and large sleepers are above 230 pounds.
For side sleepers, the Casper and Ghostbed ranked well with customers. Average sleepers gave both a “good” ranking for comfort, while smaller side sleepers believed Casper offered more hug and comfort. Conversely, larger side sleepers enjoyed sleeping on the Ghostbed more, likely because the support foam provided deeper compression support.
Changing positions, sleepers who spent the most time snoozing on their backs rated Casper slightly better than Ghostbed. While the mattresses brought in equal ratings for average and large back sleepers, smaller individuals ranked the Casper as more comfortable. Again, this is probably because Casper hugs these sleepers more than Ghostbed.
Lastly, we looked into which mattress stomach sleepers prefer. Again, the results varied across sizes. Average sleepers were comfortable on both Casper and Ghostbed, while small stomach sleepers rated Casper slightly above Ghostbed. The largest discrepancy was with large sleepers—they gave Casper the lowest “fair” rating and Ghostbed the highest “good” rating.
While both mattresses are designed to appease a wide variety of sleepers, there are subtle differences in feel between each brand. Mattress firmness ratings land on a scale from 1 to 10, with 10 being the firmest. According to this scale, Ghostbed ranks as a 6.5 out of 10. However, the thick layer of memory foam makes it feel like a 7 out of 10 on first contact. Once a sleeper settles into the mattress, it contours to the body and compresses.
Ranking under the Ghostbed, the Casper is ranked as a 6 out of 10. This may seem like an insignificant difference, but since most mattresses fall between a 5 and 7 rating, the single increment factors into overall feel. If you’re searching for a medium-firm mattress that immediately sinks under pressure, Casper may be your best bet. On the other hand, if you prefer a slightly firmer feel, Ghostbed could be for you.
Although some online foam mattresses have significant price differences, the Ghostbed and Casper are very similar. For all sizes, a Casper mattress is going to cost you more than a Ghostbed. Since both companies offer six size options, we outlined the exact prices by size in the chart below.
Customer reviews are one of the biggest factors we consider when putting together these comparisons, and the ratings for Casper and Ghostbed are almost the same. According to Amazon, Casper ranks one-tenth of a percentage higher than Ghostbed. However, the review website Sleep Like the Dead shows both designs have an 80% customer satisfaction rating. As with any online product, the reviews largely depend on the website. After researching several trusted sites, we believe these mattress should be compared on sleeping position, firmness, and price due to the similar rankings.
When deciding whether to place the Casper or Ghostbed in first place, we had great arguments on both sides. For people who prefer a firmer feel or need a mattress that keeps them cool, the Ghostbed was an obvious choice. On the other hand, Casper was chosen by sleepers who were smaller, wanted to fit a variety of sleeping positions, and liked sinking into the mattress.
In the end, we decided this comparison was too close to call. If you’re debating between these two mattresses, it’s best to look back through the review, understand your sleeping style, and pick your preferred firmness level. Also, know that both companies have great trial periods and return policies, so you can’t go wrong picking one and seeing if you sleep soundly for a few weeks.
