Based on 4,189 Actual Owner Experiences
THE GOOD. Innerspring beds have been the most popular mattress type for many decades. Their popularity is due mainly to three factors: 1.) People are familiar with them; 2.) they are widely available, and; 3.) they come in a variety of firmness and comfort levels to suit personal preference.
Several models can be inexpensive, and some provide good motion isolation making them couple friendly. Innerspring beds may also be more suitable in certain ways for romantic activity than other mattress types.
THE BAD. Compared to most other mattress types, innerspring beds overall have significantly lower owner satisfaction due mainly to below-average durability and longevity.
Durability / longevity complaints from owners contribute to many innerspring mattress manufacturers having less-than-stable Better Business Bureau ratings. In addition, some models have poor motion isolation and can squeak, creak or clunk when moved on.

Innerspring Mattress Buying Tip
Our innerspring / coil mattress ratings and research findings are based on over 4,100 consumer experiences that were collected from diverse and credible sources, namely online message boards. Learn more about our unbiased, accurate research methodology.
The ratings and comments below describe how innerspring mattresses overall are evaluated by actual owners. For information on specific brands, see the sections following this one.
|Owner satisfaction||d||Owner satisfaction among the various innerspring mattress brands can vary somewhat, but – overall – innerspring mattresses have 62% owner satisfaction. ( ) In comparison, the other mattress types (memory foam, air, latex, water, futon) all have 75% or higher satisfaction. It should be noted that owner satisfaction for innerspring mattresses is often high initially, but tends to fall significantly as durability / longevity problems emerge.|
|Durability / longevity||d+||Significant mattress sagging that occurs within three years and undermines comfort and / or support is reported by at least 25% of owners. No other mattress type has as high a rate of sagging. Innerspring mattresses with pillow tops / thick comfort layers are especially likely to have longevity issues. Learn more.|
|Affordable||c||Prices for innerspring beds can vary widely ($160-$10,000+) mainly due to the type of design and the amount / type of material used. The average price paid is around $1,600 for a queen. Owner experience data shows that higher priced brands / models do not tend to provide higher satisfaction than lower priced ones. However, low-priced innerspring mattresses (those below $500) are often purchased for temporary or occasional use and are often not well suited for long-term, regular use.|
|Firmness variety||A||The beds are available in a wide variety of firmness levels, from ultra firm to ultra soft to everything in between.|
|Less pain / pressure points||c||Innerspring mattresses – initially – often provide above average relief for pain and pressure. As the beds age, however, mattress sagging and compression can result in significant discomfort and even pain, including back pain, for about 20% of owners. See mattresses and pain for more analysis.|
|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 innerspring / coil system and materials used. Pricier models tend to provide good motion isolation.|
|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.|
|No sleeping hot||c+||Innerspring beds overall tend to not act as a heat trap. However, 10% of owners with models that have a memory foam and or latex layer report substantial heat buildup.|
|Good for sex||b-||On this issue, innerspring mattresses can have certain attributes that most other mattress types lack, such as a bouncing effect. Poor durability and a resulting lack of comfort can, however, undermine romantic activity. See mattresses and sex for complete analysis.|
|No noise||c||Innerspring beds may squeak, creak or make some other noise, especially as they age. Cheaper models with unsophisticated coil systems tend to be noisier than more expensive, advanced models. Learn more.|
|No flipping / rotating||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||Pricier, thicker models tend to weigh the most.|
|Warranties||c||About 20% of owners say that warranties lack adequate coverage for sagging. Warranty lengths tend to range from 10-25 years. See mattress warranties: what you should know.|
|Return policies||c||Policies depend on retailer, but most returns are accepted for 20-90 days and usually only for exchange. Return fees are common. See returning a mattress: what you should know.|
|Availability||A||Innerspring mattresses, unlike some other bed types, are widely available both in showrooms and online.|
|Reputation of Innerspring Mattress Companies||C||The reputation of innerspring bed companies / manufacturers overall as a group is no better than fair. The rating is an average based on a combination of metrics including Better Business Bureau ratings and stability of ratings, number of Better Business Bureau complaints / business size ratio, years in business, product ratings, and customer service ratings.|

As most mattresses age and wear, regardless of their type, they tend to sag or compress and, as a result, lose at least some of their supportiveness and comfort. This is normal.
Premature sagging / compression, however, occurs when the mattress is relatively new, namely within three years of ownership.
According to our research, innerspring mattresses have the most problem, by far, with premature sagging / compression compared to the other bed types. At least 25% of innerspring mattress owners in our research report the problem. Sagging / compression-related problems are by far the top innerspring mattress owner complaint.
A lack of mattress turning and or flipping is not likely the main cause of premature sagging / compression in most cases because many people who report a problem claimed to turn / flip their mattress regularly if possible.
In addition, a person's weight does not appear to be a main cause for the problem since many people who said they weigh less than 170 pounds reported sagging / compression.
The cause of the problem seems to be largely 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 thin or no comfort layer. (See the buying tip for a way to easily replace the comfort layer.)
However, there appear to be other causes as well for sagging including but not limited to the following: a one-sided mattress which cannot be turned to avoid uneven wear / compression; the type of upholstery used as well as the upholstery's grade of quality; the type and quality of insulator, padding and wire or netting layer that keeps the upholstery from sinking into the coils; the quality of steel used for the coils; the number of helicals (connecting wires) used and; the overall quality of construction.
Our most recently 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 years. But more data will have to be collected as it becomes available to determine if owner satisfaction is indeed improving.
A fairly common complaint from innerspring mattress owners is that, in their opinion, the mattress warranty does not provide adequate coverage for sagging and compression. Owners may say their mattress is sagging / compressing badly (often to an extent that causes the bed to be uncomfortable and even pain causing), yet the sagging / compression is not deep enough to be covered by warranty.
The table below shows, by mattress type, the average sagging / compression depth needed for warranty coverage to begin. The smaller the number (depth in inches), the better the warranty coverage. Consequently, innerspring mattresses tend to have the poorest sagging / compression warranty coverage.
|Sagging / Compression Depth Required|
|Innerspring||Greater Than 1.5 Inches|
|Memory Foam||Greater Than 1.1 Inch|
|Latex||Greater Than 1 Inch|
Although the half-inch difference above may not seem significant, our mattress pain research suggests that even a small amount of (or small increase in) sagging / compression can cause pain, especially back pain.
There are seemingly countless coil types, but almost all of them fall under one of the four types discussed below. As you will see, each coil type has its own advantages and disadvantages.
1. Bonnell Coil. Bonnell coils are hour-glass shaped and a simple design. They are typically found in 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 tend to be widely 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 wrapped in advanced fabric designed to minimize friction and maximize strength. The coils tend to provide consistent distribution of support as well as good motion isolation. Pocket coils are typically found in mid- to higher-priced mattresses because of their advanced manufacturing and assembly requirements.
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.
The following comparison (based on actual owner experiences) shows what tends to be true; a particular brand, model or individual mattress may go against these findings.
|Durability / lifespan||C-||C||C+||D+|
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 which is based on thousands of actual owner experiences, however, shows little correlation between coil count and owner satisfaction or coil count and mattress longevity / durability overall. Nevertheless, heavier persons should probably buy an innerspring mattress with a high coil count as this may result in improved supportiveness and mattress strength.
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 of the comfort layer largely determine the firmness level of a mattress.
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).
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. 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.
3. Memory foam. This material is becoming increasingly common. Its purpose is to provide softness as well as a contouring and cradling effect for the sleeper. It can be effective in reducing motion transfer and minimizing pressure points. Memory foam is more likely than regular foam to off gas. A greater quantity / thickness of memory foam present on the mattress 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.
4. 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. Latex may off gas due to synthetic content. It may also act as a heat trap, but usually not to the full extent of memory foam.
5. Polypropylene. This material is a thermoplastic polymer. It is usually found in only the least expensive innerspring mattresses. Its comfort and durability are questionable.
|Regular Polyurethane Foam||Fiber||Memory Foam||Blended Latex||Polypropylene|
|Not a heat trap||B||b||C-||C||b|
|No off gassing||C+||b+||D||C-||c|
Instead of buying a mattress with a comfort layer, consider buying the mattress and comfort layer separately as described below. This buying strategy often minimizes both potential durability problems and cost.
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. Firm models also tend to be highly affordable because they lack padding.
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.
