We test 10 different factors that impact the performance, comfort, and value of the mattress. Testing categories include:

1. Cooling
2. Sinkage
3. Motion Transfer
4. Response
5. Bounce
6. Edge Support
7. Sex
8. Pressure Relief
9. Off-Gassing
10. Company

In the following side-by-side tests we focused our comparisons on 6 mattress models, 3 from Casper and 3 from Ghostbed. We choose the models that were the most popular from each brand.

Cooling performance on Casper and GhostBed mattresses are nearly equal, but GhostBed has a slightly higher cooling average.

Based on the 6 mattresses compared in this review, Casper has an average cooling score of 9.16 while GhostBed has a cooling average of 9.33.

Cooling Test	Score	Baseline	Max Temp	Ending Temp
Casper Original	9.0	64.2°	85.2°	-11.9°
Casper Original Hybrid	9.5	68.8°	86.5°	-11.5°
Casper Wave Hybrid	9.0	77.8°	91.0°	-7.2°
Ghostbed Classic	9.0	84.0°	92.7°	-5.2°
Ghostbed Flex	9.5	73.2°	85.7°	-9.6°
Ghostbed Luxe	9.5	83.5°	89.7°	-3.4°

• Baseline Temperature – the temperature of the mattress before anyone lies on it
• Maximum Temperature (0 minute) – the temperature of the mattress after lying on it for 15 minutes
• Ending Temperature (after 5 minutes) – the temperature of the mattress after being lied upon and having no one on it for 5 minutes

That being said, Casper has one mattress, not included in this side-by-side, which outperforms all mattresses listed here with a perfect score of 10 out of 10—the Casper Snow.

Below, you can watch a video of how the heat dissipates on each mattress during our cooling test. For this test, we lie on the mattress for 15 minutes, get off the mattress, and then take periodic surface-level temperature measurements.

Comparing Casper and GhostBed, Casper has mattress options with less sinkage overall (1.69″ – 2.38″), while GhostBed has deeper sinkage overall (2.15″ – 2.90″).

Sinkage Test	Sinkage Depth	Max Sinkage
Casper Original	Very Minimal	1.69″
Casper Original Hybrid	Minimal	1.91″
Casper Wave Hybrid	Deep	2.38″
Ghostbed Classic	Deep	2.34″
Ghostbed Flex	Moderate	2.15″
Ghostbed Luxe	Extremely Deep	2.90″

For comparison, the average level of sinkage across mattresses tested to date is 2.18″.

The Casper Original, Casper Original Hybrid, and GhostBed Flex all have less sinkage than average.

The Casper Wave Hybrid, GhostBed Classic, and GhostBed Luxe have deeper sinkage than average.

The level of sinkage for each mattress is documented in the images and table below.

Looking at motion transfer, GhostBed is the clear winner, with significantly lower levels of motion transfer than we see on Casper.

Motion Transfer Test	Score	Acc. Range
Casper Original	8.4	11.30 m/s²
Casper Original Hybrid	8.5	10.87 m/s²
Casper Wave Hybrid	8.0	12.88 m/s²
Ghostbed Classic	10	4.80 m/s²
Ghostbed Flex	9.8	5.61 m/s²
Ghostbed Luxe	10	4.90 m/s²

The average level of motion transfer across all mattresses tested to date is 8.15 m/s².

All GhostBed mattresses were significantly lower than that, with the best-performing GhostBed being the GhostBed Classic at only 4.80 m/s².

All Casper mattresses had higher levels of motion transfer than average, with the most motion transfer coming from the Casper Wave Hybrid—12.88 m/s², 42% more than the average level of motion.

The level of motion transfer on each mattress is also documented in the videos below.

For material response time, both Casper and GhostBed mattresses had good performance, all at average or faster than average.

Response Test	Score	Mostly Recovered	Completely Recovered
Casper Original	10	0.2 seconds	0.7 seconds
Casper Original Hybrid	10	0.2 seconds	0.4 seconds
Casper Wave Hybrid	10	0.2 seconds	0.8 seconds
Ghostbed Classic	10	0.4 seconds	1.0 seconds
Ghostbed Flex	10	0.4 seconds	0.8 seconds
Ghostbed Luxe	10	0.2 seconds	0.3 seconds

The average speed of material response time is 0.4 seconds to be mostly recovered and 0.9 seconds to be fully recovered.

These mattresses all contain responsive materials that return to their original shape quickly and do not leave sleepers feeling “stuck”.

The level of responsiveness for each mattress is documented in the videos below.

While bounce is a bit more of a preferential factor than these other testing categories, we do see some differences between Casper and GhostBed.

Casper has moderate to high bounce, with a range of 2.57″. GhostBed has a slightly wider spread, with a bounce range of 2.65″.

Bounce Test	Bounce Height	Bounce Range
Casper Original	Moderate	9.80″
Casper Original Hybrid	Moderate	8.21″
Casper Wave Hybrid	High	10.78″
Ghostbed Classic	Low	8.00″
Ghostbed Flex	High	10.65″
Ghostbed Luxe	Moderate	8.58″

The average level of bounce is 9.63″, comparing all mattresses tested to date.

The Casper Wave Hybrid has the highest level of bounce by any Casper mattress tested to date (closely followed by the Casper Nova Hybrid at 10.46″.)

The GhostBed Classic has the lowest level of bounce, with only 8.0″ of bounce. Both the Casper Original Hybrid, GhostBed Classic, and GhostBed Luxe all have lower levels of bounce than the average.

The level of bounce for each mattress is documented in the videos below.

Concerning edge support, both Casper and GhostBed have some mattresses that are exceptional.

Check out the table below to see how each mattress compares regarding bounce levels.

Edge Support Test	Score	Max Sinkage	Lying Support
Casper Original	9.6	3.75″	Excellent
Casper Original Hybrid	10	2.25″	Excellent
Casper Wave Hybrid	9.9	3.25″	Very Good
Ghostbed Classic	9.3	4.50″	Excellent
Ghostbed Flex	9.9	3.25″	Excellent
Ghostbed Luxe	9.6	3.75″	Excellent

The average score for edge support is 9.37, with a max sitting sinkage of 4.19″.

Of these size mattresses only one falls below the average edge support performance, the GhostBed Classic.

In this comparison, both foam and hybrid mattresses had good performance, regardless of mattress type.

The mattress with the absolute best edge support among all mattresses in this comparison is the Casper Original Hybrid. The Original Hybrid has only 2.25″ of sinkage when seated directly at the edge of the mattress and excellent support when lying.

The level of edge support of all mattresses is documented in the images below.

Although sleep preferences are largely individual, the reality is that many couples share a bed together.

This part of our scoring looks at the mattress expected sex performance based on a number of performance factors.

The best mattresses for sex have high bounce, good edge support, quiet materials, and good pressure relief and cooling.

These 5 factors make up the NapLab sex performance score and from these factors, we can generate a sex score, unique to each mattress.

The table below shows how sex performance varies between Casper and GhostBed mattresses.

Sex Test	Sex Score	Bounce	Edge Support	Noise	Pressure Relief	Cooling
Casper Original	9.8	10	9.6	10	9.0	9.0
Casper Original Hybrid	9.7	9.6	10	10	9.5	9.5
Casper Wave Hybrid	9.9	10	9.9	10	10	9.0
Ghostbed Classic	9.5	9.5	9.3	10	9.5	9.0
Ghostbed Flex	9.8	10	9.9	9.0	9.5	9.5
Ghostbed Luxe	9.6	9.6	9.6	10	9.5	9.5

As you can see, sex performance on both Casper and GhostBed mattresses ranges from good to great.

Performance on the hybrids tends to be better than foam mattresses, thanks to generally higher levels of bounce and better edge support.

But as we see with the Casper Original, a foam mattress with high bounce and good edges can perform as high as any comparable hybrid.

Pressure relief is a combination of a quality comfort layer, a sufficient support layer, and high-quality materials that promote spinal alignment, regardless of your sleeping position.

Pressure Relief Test	Score	Comfort Layer	Support Layer
Casper Original	9.0	3.5″	7.0″
Casper Original Hybrid	9.5	3.5″	7.0″
Casper Wave Hybrid	10	5.0″	7.0″
Ghostbed Classic	9.5	3.5″	7.5″
Ghostbed Flex	9.5	2.0″	9.5″
Ghostbed Luxe	9.5	5.5″	7.5″

In the case of Casper vs. GhostBed, it was a bit of a wash, as both brands had good pressure relief for the most part. They have thick comfort layers and thick support layers as well.

Having thicker layers increases the chance of heavier sleepers finding these mattresses to be comfortable and supportive.

For comparison, the average level of comfort material across all mattresses tested to date is 4.15″.

The mattress with the highest score in this comparison is the Casper Wave Hybrid (10 out of 10 score). This mattress has a 5.0″ comfort layer and a 7.0″ support base.

The mattress with the lowest pressure relief score is the Casper Original (9 out of 10 score). The Original has only a 3.5″ comfort layer followed by a 7.0″ support layer. This comfort layer and support layer are both thinner than others in this comparison.

At the end of the day, it’s the thinner profile that hurts the Casper Original when it comes to pressure relief.

Right out of the box, off-gassing odors are strong on both Casper and GhostBed mattresses.

But that being said, the odor lingers significantly longer on the Casper mattresses.

Off-Gassing Test	Score	Initial Smell	Off-Gassing Period
Casper Original	8.8	Strong	15 days
Casper Original Hybrid	8.8	Strong	15 days
Casper Wave Hybrid	9.1	Strong	11 days
Ghostbed Classic	9.8	Strong	2 days
Ghostbed Flex	9.7	Strong	4 days
Ghostbed Luxe	9.6	Strong	5 days

The average off-gassing period is 4 days. On GhostBed, their brand average is 3.6 days. But on Casper, their brand average is 13.6 days. This is nearly 4X the time it takes GhostBed to off-gas.

Both Casper and GhostBed have similar company scores, but GhostBed does outperform in trial (by 1 night) and warranty (by 10-15 years).

Company	Casper	Ghostbed
Trial Period	100 nights	101 nights
Warranty	10 years	20-25 years
Shipping	$0	$0
Returns	$0	$0
Country of Origin	USA	USA

The average trial period is 165 nights. Both Casper and GhostBed are shorter than the average, but that still gives sleepers over 3 months to decide if they like the mattress.

For most sleepers, that should be more than sufficient, although a longer trial is always a perk.

What about the warranty?

Among all mattresses tested to date, 28% have lifetime warranties. The average of the other 72% of mattresses is 14 years.

Based on these numbers, Casper is shorter than most mattresses. GhostBed is longer than 72% of mattresses, but shorter than the 28% of mattresses that boast a lifetime warranty.

Looking at all available mattresses, Casper ranges in firmness from 4.5 to 6.5 out of 10 and GhostBed mattresses range from 6 to 6.5 out of 10.

Of these two brands, Casper has the greater firmness range.

Ghostbed Luxe	6	Medium-Firm	Read Review

Casper and GhostBed mattresses are equally capable of providing great support in most cases. While there are mattress models that perform better than others for certain sleepers, there are really no mattresses that stand out as just being totally unacceptable.

Not sure which firmness is right for you?

Use the table below to better determine the firmness range that may be best suited for you, based on your personal weight and preferred sleeping position.

Note: Heavier sleepers may do better on a mattress with a thicker profile, as they tend to have better support. For these sleepers, I would recommend the Casper Snow, Casper Wave Hybrid, GhostBed Luxe or GhostBed Flex.

Design

Both Casper and GhostBed have a mix of 100% foam or hybrid mattresses. Also, they both use a blend of foams. Mattresses with a blend of materials tend to have a more balanced feel compared to 100% memory foam mattresses or coil-on-coil mattresses.

Design	Type	Thickness
The Casper	Foam	9″
Casper Original	Foam	10.5″
Casper Select	Foam	12″
Casper Original Hybrid	Hybrid	10.5″
Casper Snow Hybrid	Hybrid	12″
Casper Nova Hybrid	Hybrid	12″
