What You Need To Know

THE GOOD. Innerspring beds have been the most popular mattress type for many decades due mainly to three factors: 1) People are familiar with them; 2) they are widely available, and; 3) they come in a variety of price, firmness and comfort levels.

Also, many models now provide good motion isolation making them couple friendly. The beds may also be more suitable in certain ways for romantic activity than other mattress types.

THE BAD. Innerspring beds overall have lower owner satisfaction than most other mattress types due mainly to below-average durability and longevity.

The beds tend to provide only fair long-term pain and pressure-point relief. Some models may produce significant noise and off gassing.

Innerspring Mattress Ratings: Overall As a Group

The ratings and comments below describe how innerspring mattresses overall are evaluated by actual owners. For information on specific brands, see the section following this one.

Owner satisfaction d Owner satisfaction among the various innerspring mattress brands can vary somewhat, but the mattresses overall have 63% owner satisfaction when used by an adult regularly / everyday. (Satisfaction is often at least 80% when used only temporarily / occasionally / lightly.) By comparison, other mattress types – memory foam, air, latex – all have 78% or higher satisfaction when used regularly / everyday. Learn more about innerspring bed owner satisfaction.
Durability / longevity d+ 25% of owners who use their innerspring bed regularly / everyday report within three years of ownership sagging occurring to an extent that undermines comfort and / or support. No other mattress type has as high a sagging rate. Learn more.
Affordable c Prices for innerspring beds can vary widely ($100 to $10,000+) mainly due to design type and amount / type of material used. The average price paid is around $1,600 for a queen.
Less (back) pain c Initially, innerspring mattresses often provide relief from pain, including back, hip and shoulder pain. Mattress sagging, however, may cause significant discomfort and pain, including back pain, for about 20% of owners. See mattresses and pain for more analysis.
Pressure point relief C Initially, innerspring mattresses often provide relief from pressure points. Age and wear, however, often result in compression of the comfort layer(s) which can increase pressure points and discomfort.
Firmness variety B Brand names (such as Serta, Sealy, Simmons) offer a variety of firmness options. Off-brands tend to offer only medium to firm models.
Easy to move on / get up off b- Those models with a thick memory foam layer have potential to provide some resistance to movement. Sagging can also impede movement.
Motion isolation c+ Motion isolation refers to how well the bed keeps movement made by one person from being felt by another. Motion isolation for innerspring mattresses can vary from poor to good depending on the coil system and materials used. Pricier models tend to provide at least somewhat superior motion isolation compared to cheaper models.
No noise c+ Some cheaper models are most prone to making noise, including squeaking, creaking and clunking. Models with pocketed coils tend to have the fewest noise complaints. Learn more.
Large person friendly C- The durability of low-priced innerspring mattresses (under $600 for a queen) is not well suited for large people (200+ lbs) especially over the long term. Large people also tend to report more noise issues and lack of edge support from their innerspring mattress than lighter people.
No initial odor / off gassing c+ About 10% of innerspring mattress owners complain of off gassing, which is the release of a chemical-like odor that occurs when the mattress is new. Those models with a thick regular foam or memory foam comfort layer tend to have the greatest off gassing problem.
Not a heat trap c+ 10% of owners of models with a memory foam and or latex layer report sleeping hot at least some of the time.
Good for sex b- On this issue, innerspring mattresses can have attributes that other mattress types lack. Mattress sagging and a resulting lack of comfort can, however, undermine romantic activity. See mattresses and sex for complete analysis.
Low mainten- ance c+ Most models are "no-flip." To combat sagging, owners often report the need to rotate their bed fairly regularly which can be difficult given the weight of the beds.
Lightweight c The mattresses can weigh 35-150+ lbs with the average queen weighing about 93 lbs. Pricier, thicker models weigh the most.
Warranties c+ About 15% of owners say that warranties lack adequate coverage for sagging. Warranty lengths tend to range from 5-25 years. See mattress warranties: what you should know.
Return policies c Policies depend on the retailer, but most returns are accepted for 20-90 days and usually only for exchange. Return fees are fairly common. See returning a mattress: what you should know.
Availability A Innerspring mattresses, unlike some other bed types, are widely available in stores for both "test driving" and buying.

Innerspring Mattress Owner Satisfaction by Year

The graph below shows that after the first two to three years, innerspring bed owner satisfaction overall is somewhat lower than that of all mattress types overall (innerspring, memory foam, latex and air). This is mostly due to innerspring beds in general having somewhat worse longevity / durability than the other mattress types.

innerspring mattress vs all

Main Owner Complaint: Mattress Sagging

Compared to other bed types, innerspring mattresses have the most problem with sagging. Sagging is the loss of a level and supportive sleep surface. Sagging can include the development of body impressions, "sink holes," and "peaks and valleys." About 25% of innerspring mattress owners in our research report the problem. Sagging is by far the top innerspring mattress owner complaint.

* estimated to be at least 1.5" depth

Causes of Sagging

A lack of mattress rotation is not likely a main cause of sagging because many people who report sagging claim to rotate their mattress regularly.

In addition, a person's weight does not appear to be the main cause of the problem since many people who weigh less than 170 pounds report sagging.

The cause of the problem seems to be at least partly related to the comfort layer. Thick pillow top / comfort layer models tend to be at least two times more likely to have sagging / compression than those models with a thin or no comfort layer. See the truth about pillow top mattresses. Also see the buying tip for a way to possibly minimize comfort layer problems.

Other causes of sagging may include: 1) one-sided designs which cannot be flipped to avoid uneven wear / compression; 2) king-size models that lack the construction strength needed to properly support two people especially in the middle; and 3) an inadequate, sagging or poorly assembled foundation.

Don't make 'em like they used to?

While most of our innerspring mattress data is based on owner experiences of the past ten years, a limited amount goes back further. This older data suggests that innerspring mattresses of earlier decades had, or at least were perceived to have, superior durability / longevity compared to those of today.

The data suggests that in the 1990s innerspring mattress durability / longevity may have taken a turn for the worse. Possible reasons for this include cost cutting and the introduction of both no-flip designs and thick but less-than-resilient comfort layers.

Possible Improvement

Our most recent collected owner experience data suggests that the durability of innerspring mattresses overall may be improving somewhat. In addition, the number of Better Business Bureau complaints filed against innerspring mattress companies has fallen quite dramatically in the past two to three years. This may suggest improved durability or it may be due to some other factor such as improved customer service. More data will need to be collected as it becomes available to determine if durability is indeed improving.

Coil Types

There are seemingly countless coil types, but almost all of them fall under one of the four types discussed below. Each coil type has its own advantages and disadvantages.

1. Bonnell (Open) Coil. Bonnell coils or open coils are hour-glass shaped and have a simple design. They are typically found in a limited number of low-priced mattresses. They are generally supportive, but they tend to have no better than fair durability / longevity and motion isolation.

2. Offset Coil. Offset coils are often used in mid- to higher-priced mattresses. They are similar to Bonnell coils but have better spring action and supportiveness. Some variations have good motion isolation. Durability / longevity, however, can be a weakness as the mattress may sag toward the middle as the coils wear and age.

3. Pocket Coil. Pocket coils are individual coils often wrapped in fabric. The coils tend to provide consistent distribution of support as well as good motion isolation. The use of pocket coils is becoming widespread in mattresses of all price points. Pricier mattresses, however, often use a more advanced pocket coil design than less expensive mattresses. Consumers seeking a highly "springy" mattress may want to avoid this coil.

4. Continuous Coil. The system consists of coil rows made of continuous wire that run head to toe. This system is often present on low- to mid-priced mattresses. While it is durable because each coil gets support from ones next to it, the system tends to not be especially supportive. In addition, because the system consists of one piece, it tends to provide no better than fair motion isolation making it a less-than-ideal choice for couples.

Coil Count

Coil count refers to the number of coils in the mattress. Most queen innerspring mattresses have a coil count of 450-900 with 725 being about average. Mattresses with a higher coil count are more expensive than mattresses with a lower coil count, all other things being equal.

Our research, however, shows little correlation between coil count and owner satisfaction or coil count and mattress longevity / durability overall. Nevertheless, heavier persons may want to consider buying an innerspring mattress with a high coil count as this may result in improved supportiveness and mattress strength.

Coil Gauge

Coil gauge is a measurement of how large the coil wire is in diameter. Mattress coil gauge often ranges from 12 to 15. The higher the gauge, the thinner the coil wire and the softer and springier the feel of the bed. Coil gauge in conjunction with the thickness and composition of the comfort layer largely determines the firmness level of a mattress.

Innerspring Mattress Comfort Layer Material Comparison

In addition to having supportive coils, innerspring mattresses have a comfort layer(s). Any number of the following materials in varying amounts / thickness may be used in this layer(s).

Comfort layer materials

1. Regular polyurethane foam. This material is widely used, and its purpose is to provide softness. Its durability tends to be questionable; those mattresses with a thick layer of regular polyurethane foam tend to have an above-average number of sagging / compression complaints. This foam can also off gas, that is, release a chemical-like odor when it is new. A greater quantity / thickness of foam present on the mattress means a greater likelihood of noticeable and potentially bothersome off gassing.

2. Memory foam (non-infused). This material is often widely used and provides softness as well as a contouring and cradling effect for the sleeper. It can be effective in minimizing pressure points and, to a lesser extent, reducing motion transfer. Memory foam is more likely than regular foam to off gas. A greater quantity / thickness of memory foam present means a greater likelihood of noticeable and potentially bothersome off gassing. In addition, a mattress with memory foam, especially memory foam which is high density, is two to three times more likely to act as a heat trap than a mattress without memory foam.

3. Gel-infused memory foam. It is increasingly common for mid- to higher-priced innerspring mattresses to have at least one layer of gel memory foam – foam that is infused with millions of tiny gel beads. This material is touted to sleep cool longer than regular memory foam, and it does tend to reduce heat trap complaints by about 30%. The amount of gel foam in a mattress also seems to be a factor. Beds with two inches or more of gel foam, especially at the top of the mattress, tend to sleep cool longer than those beds with less than two inches.

4. Graphene-infused or diamond particle-infused memory foam. A small number of innerspring mattresses use memory foam infused with graphene or diamond particles – both conductors of heat. Their effectiveness, however, in reducing heat trap complaints is unknown at this time given their currently limited use.

5. Latex. This material is used less often than memory foam. Its purpose is to provide pressure relief. The latex used is often blended latex, that is, a combination of natural and synthetic latex. The durability of latex that is often used in innerspring mattresses is questionable as it can develop body impressions. The latex may off gas and act as a heat trap.

6. Fiber. Polyester material or cotton is often used to provide softness. Durability tends to be highly questionable; those mattresses with a thick layer of polyfiber tend to have the most sagging / compression complaints from owners.

7. Polypropylene / Celestra. This material is a thermoplastic polymer. It is found in a limited number of inexpensive innerspring mattresses. Its comfort and durability are questionable.

Buying Tip

Instead of buying a mattress with a thick comfort layer, consider buying the mattress and comfort layer separately as described below. This buying strategy often minimizes both potential durability problems and cost.

How to do it

Purchase the firmest innerspring mattress you can find – that is, one with the least amount of padding. The advantage of this is that firm models tend to have fewer and less severe sagging problems than do models with thick comfort layers / pillow tops. Firm models also tend to be highly affordable because they lack significant padding / tops.

Then, if you wish to soften the mattress, purchase a mattress topper and place it on the mattress. (The thicker the topper is, the softer it tends to make the mattress.) The advantage of this is that if the topper deteriorates, compresses or sags, then only it needs to be replaced as opposed to the entire mattress.

While this buying strategy is not widely practiced, those consumers who have used it tend to report good comfort, durability and money-saving results.
