How is Sealy Posturepedic Spring Different?

The Sealy Posturepedic Spring is an 11.5″ coil mattress with an overall performance that is significantly below average, but also a price tag that is below average as well.

Advantages

Aside from the price, other advantages of the Posturepedic Spring mattress include a very fast material response time and better-than-average edge support. Off-gassing is also faster than average, although this tends to be a minor factor for most sleepers.

Neutral Factors

Neutral factors include deep sinkage and moderate levels of bounce. Both of these factors are considered neutral since sleeper preferences can vary and these factors could easily become advantages or disadvantages, depending on the feel you’re looking for.

Sex performance is also neutral since the 8.4 performance score is right at the average level.

Disadvantages

Disadvantages of the Sealy Spring mattress include poor cooling with higher levels of heat retention, higher levels of motion transfer, and poor levels of pressure relief.

This mattress has 3.5″ of comfort material, only 0.5″ less than the average, but the quality of materials is really what hurts this mattress more than anything.

The Sealy Posturepedic Spring has poor cooling. During our tests, I felt a significant degree of heat retention around my body.

• 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 (5 minute) – the temperature of the mattress after being lied upon and having no one on it for 5 minutes

The mattress feels quite warm and does not seem to breathe well. The mattress is equipped with a 2.0” quilted cover and a 1.5” poly foam comfort layer. Neither of these layers look or feel particularly high quality.

The 1.5” poly foam is very stiff and has a noticeable “crunchiness” to the feel. We’ve experienced this foam (or at least foams that are substantially similar) in other Sealy mattresses we’ve tested, including the Sealy Posturepedic Hybrid, Sealy Posturepedic Plus RidgeCrest II, and Sealy Posturepedic Carver.

In my view, this foam is simply incredibly basic. It is notably worse quality compared to many other poly foam types we’ve tested.

In addition, it is also the likely reason for much of the cooling and pressure relief issues we experienced on the Posturepedic Spring and other Sealy Posturepedic mattresses we’ve previously tested.

In our objective temperature tests, we measured a max surface level temperature of 93.3° F. This is 3.6° more than the average of 89.7° F, based on all of our tests to date.

Heat Dissipation Over Time

When we consider the combination of objective data, my subjective experiences, and an analysis of the materials, I’m confident in my view that cooling is poor.

The Sealy Posturepedic Spring has deep sinkage. During our tests, we measured a pressure point sinkage depth of 2.47″. This is 0.32″ more sinkage than the average sinkage depth of 2.15″, based on all of our tests to date.

The level of sinkage is documented in the image below.

The mattress creates a more generalized body-contouring hug. Despite the deeper level of sinkage, the foams don’t hug or contour to the exact shape of the body in the same way that a memory foam or many other types of poly foam will.

Even so, between the quilted cover and 1.5” foam comfort layer, the mattress does still create a modest level of hug. It’s just not the dramatic and exacting memory foam hug. Instead, the mattress has a more classic coil type of a feel.

This is neither good nor bad, but it is a specific feel. Those who prefer the feel of coils and more traditional mattresses are more likely to enjoy the feel.

The Sealy Posturepedic Spring has a low level of motion transfer. During our tests, we measured a total acceleration range of 9.52 m/s². This is 8% more motion transfer than the average of 8.79 m/s².

The quilted cover appears to be doing much of the heavy lifting with respect to reducing motion. The fabric used on the cover is a little loose, which helps to avoid abruptly tugging the fabric during sleeper movements. All that said, I am surprised at the relatively low level of motion.

Typically, coil mattresses struggle more with motion transfer. Nevertheless, the Posturepedic Spring did a great job at keeping motion in check.

The level of motion transfer is also documented in the video below.

In our motion transfer chart, which visualizes our accelerometer data, we can see the highest motion peaks from 0 to 0.14 seconds.

We see a significant secondary spike from 0.50 to 0.65 seconds, after which motion rapidly declines. By 1.15 seconds we’ve returned to near-zero levels of energy. While I am pleased with the motion intensity, the motion duration is far from ideal. Even so, it is far more typical of what we expect from coil mattresses.

The mattress has a significant secondary energy spike and a motion duration that extends far beyond the average duration. Nevertheless, given the fact the motion peaks were still within the low range, it’s hard to complain too much.

The Sealy Posturepedic Spring has an extremely fast mostly recovered response time and a very fast fully recovered response time.

In our mostly recovered test, we measured a recovery speed of 0.2 seconds, which is 0.20 seconds faster than the average of 0.40 seconds, based on all of our tests to date.

In our fully recovered responsiveness test, we measured a recovery speed of 0.6 seconds, which is 0.30 seconds faster than the average of 0.90 seconds.

The level of responsiveness is documented in the video below.

While these responsiveness speeds aren’t the fastest we’ve tested, they are still plenty fast enough to make the mattress easy to move around on and avoid any type of a stuck feeling. I expect most sleepers will find response at these levels to be sufficient. 

The Sealy Posturepedic Spring has a moderate level of bounce. During our tests, we measured a total bounce height of 9.68″. This is 0.17″ more bounce than the average of 9.51″, based on all of our tests to date.

The level of bounce is also documented in the video below.

Spring and coil mattresses typically have more bounce and that’s exactly what we measured with this mattress. The limited 3.5” comfort layer and 7.0” spring unit work together to create a higher-than-average level of bounce.

Ideally, I want to see 8-12″ of total bounce height. The Sealy Posturepedic Spring is right in the middle of that range. This creates plenty of bounce to facilitate ease of movement and amorous activity.

The Sealy Posturepedic Spring has excellent sitting and lying edge support.

In our sitting edge support test, we measured a sitting sinkage compression of 3.25″. This is 0.79″ less sitting sinkage than the average of 4.04″, based on all of our tests to date. Even when sitting directly on the edge of the mattress I felt fully supported.

The level of edge support while seated is documented in the images below.

Having a more limited 3.5” comfort layer definitely helps to create more robust support at the edge.

While lying directly on the edge of the mattress, I felt that the support was excellent in all sleeping positions.

The level of edge support while lying is documented in the images below.

The Posturepedic Spring uses two rows of reinforced coils that run along the perimeter of the mattress. Those coils are having a notable impact for both sitting and lying edge support.

Overall, I’m pleased with the level of edge support performance and expect it will be a non-issue for most sleepers.

The Sealy Posturepedic Spring has good sex performance. On the positive side, bounce is high and edge support is excellent.

The mattress has a total bounce height of 9.68”, which is 0.17” more than the average. The increased bounce is the greatest single factor in helping to improve amorous activity performance.

Sex Factor	Factor Weight	Score	Rating
Bounce	65%	8.5	High
Edge Support	20%	9.7	Excellent
Noise	5%	8.0	Moderate
Pressure Relief	5%	5.0	Poor
Cooling	5%	5.0	Poor

In addition, sitting edge sinkage is also better than average with just 3.25” of sitting sinkage. This helps to extend the usable surface of the mattress. That said, it’s not all good news.

On the negative side, noise is moderate due to the relative quality of the materials and coil unit, pressure relief is poor, and cooling is also poor.

Certainly, the increased noise makes it more difficult for stealthy sessions.

In addition, the worse pressure relief and cooling can simply make the experience less comfortable.

All that said, because bounce and edge support performed well the mattress still earned a good score. Even so, it still leaves much to be desired with respect to comfort.

The Sealy Posturepedic Spring has a poor level of pressure relief. During our tests, I felt significant pressure points on my body.

The mattress is equipped with 3.5″ of comfort material. This means there is 0.61” less comfort material than the average comfort layer thickness of 4.11″, based on all of our tests to date.

In addition to simply having less comfort material than average, the quality of the comfort materials in the mattress leaves much to be desired. Overall, the foams simply don’t look especially high quality.

The foams already feel quite dried out (similar to how foams can feel after many years of use), don’t feel good on the body or in hand, and have a noticeable “crunchiness” to them when they are compressed.

We’ve tested other Sealy mattresses with a foam that feels the same (or at least similar) and experienced similarly disappointing pressure relief on those mattresses (which include the Sealy Posturepedic Hybrid, Sealy Posturepedic Plus RidgeCrest II, and Sealy Posturepedic Carver).

In my view, the combination of limited comfort material and relatively low quality of the foams make for a mattress that simply is not comfortable.

When I consider the material thickness, material quality, and my subjective experience with the mattress, I’m confident most sleepers will find the pressure relief to be poor.

Pressure Map – Side Sleepers

Pressure Relief (PSI)	Average	Maximum
Side Sleepers	0.18	1.31

Pressure Map – Back Sleepers

Pressure Relief (PSI)	Average	Maximum
Back Sleepers	0.10	0.66

Pressure Map – Stomach Sleepers

Pressure Relief (PSI)	Average	Maximum
Stomach Sleepers	0.10	0.95

Off-gassing on the Sealy Posturepedic Spring was strong right out of the bag and the odor lasted for 3 days.

This mattress ships uncompressed and, instead, arrives in a plastic bag the size of the full mattress.

We’ve tested over 270+ mattresses to date and of those mattresses, the majority ship vacuum-sealed and rolled into a box. The average off-gassing period is 6 days.

Based on these results, the Sealy off-gassed 3 days faster than average.

Sealy mattresses come with a 90-night trial period and a 10-year warranty. Shipping is free, but if the mattress ends up not working out, return shipping will cost of $175 out of your return.

Company Factor	Factor Weight	Score	Data
Trial Period	15%	6.0	90 nights
Warranty	10%	8.0	10 years
Shipping	5%	10	$0
Returns	20%	5.0	$175
Trust	50%	4.0	Terrible
Country of Origin	0%		USA

Comparing Sealy to over 80+ brands tested to date, Sealy struggles in many areas. The trial and warranty are both shorter than average.

For reference, the average trial is 177 nights and the average warranty is 13 years (excluding 25% of all mattresses that had a lifetime warranty).

Looking at 270+ mattresses tested to date, 80% offer free returns, 17% have paid returns, and 3% do not allow returns at all.

The Sealy Posturepedic Spring comes in two firmness options—medium soft and medium.

Medium Version

We tested the medium version of this mattress. This mattress has a medium-firm feel and we rate it a 6 out of 10 on our firmness scale.

This firmness is the most popular level and is suitable for a wide range of sleepers. Although I will also note that the mattress is firmer than I expected. Most “medium” mattresses are a touch softer than the Sealy’s medium.

If you’re looking for that true medium, I’d actually recommend the “medium soft” version.

Medium Soft Version

We estimate the medium soft version to be around a 5 out of 10, if 10 is the most firm.

Support on the Sealy Posturepedic Spring is fair. During our tests, I felt well-supported. However, I also felt significant pressure points.

For a mattress to be supportive, it must be capable of creating sufficient comfort so sleepers can lie in the same position, while also achieving a neutral spinal alignment for sleepers.

In my view, the Posturepedic Spring simply doesn’t do a great job at this. In our testing, I felt significant pressure points on my body and felt that the mattress wasn’t comfortable.

Check out the table below to see the sleeper weights and sleeping positions that would be best suited for this mattress.

Sleeper Weight	Stomach Sleepers	Side Sleepers	Back Sleepers
Under 150 lbs.	Maybe	Maybe	Maybe
150-250 lbs.	Yes	No	Yes
250-300 lbs.	Maybe	No	Maybe

The mattress is equipped with an 8.0″ support layer. This is 0.11″ thicker than the average support layer thickness of 7.89″, based on all of our tests to date. While the mattress has enough support, it wasn’t able to create enough comfort alongside support.

This makes the total support dynamic less than ideal. Based on all of my tests to date, an analysis of the materials, and my subjective experiences, I’m confident most sleepers will find support on the Sealy Posturepedic Spring is fair.

Design

The Sealy Posturepedic Spring is an 11.5″ coil mattress that comes in two firmness levels. It is designed to be a 12″ thick mattress, but falls a little short of that from our measurements.

The Sealy Spring is an extremely budget-friendly mattress, priced significantly below average, aimed at sleepers on a tight budget who like the feel of traditional coil mattresses.

Materials

The Sealy Posturepedic Spring mattress is made up of four layers. From top to bottom, the layers include:

• 2.0” quilted cover
• 1.5” poly foam
• 7.0” coil unit
• 1.0” support foam

The Cover

The cover of the mattress is a 2.0″ plush quilted cover with a convoluted poly foam. The top fabric is thin and stretchy and has tufted accents to hold the cover taut against the top of the mattress.

The sides of the mattress lack any handles or other special features, but the fabric is thicker than the fabric used on the top. This helps with durability and extends the overall lifespan of the mattress.

The Comfort Layer

The comfort layer of the Sealy Spring mattress is a 1.5″ poly foam. This is thinner than the average 4.1″ comfort layer, but the 2.0″ quilted cover certainly helps.

Despite the cover, this mattress struggled to provide good pressure relief during our tests and the quality issues of the comfort layer is likely the culprit of its poor performance.

The Support Layer

Beneath the poly foam is a 7.0″ coil unit. While Sealy doesn’t disclose the exact gauge or count of these coils, the performance tests reveal some issues with support.

Product Evolution

The Sealy Posturepedic Spring mattress was released around 2018. Since it launched, there have been no known material or design changes made to the mattress.

That said, the Sealy has been making similar spring mattresses for decades. This is merely the more recent generation of their budget-friendly spring mattress.
