THE GOOD. Innerspring mattresses are the most popular mattress type mainly for five reasons: 1) consumer familiarity, 2) wide availability, 3) relative affordability, 4) many firmness and comfort options, 5) romance friendliness.
THE BAD. Innerspring mattresses overall have lower owner satisfaction than other mattress types due mainly to below-average durability / longevity. They tend to provide only fair long-term pain and pressure-point relief. Noise is possible.
THE MATTRESSES: Innerspring coils provide support – not foam, latex or air. Comfort layer material usually consists of regular foam, fiber and perhaps memory foam. Models with at least two inches of memory foam are often called hybrids; Sleep Like The Dead rates hybrids separately from innerspring mattresses.

Innerspring Mattress Buying Tip
The innerspring mattress ratings and research findings are based on over 7,900 consumer experiences collected from diverse and credible sources.
The ratings below show how innerspring mattresses as a group compare to other mattress types as evaluated by owners. For information on specific brands, see the following section.
|Owner satisfaction||d+||Owner satisfaction among innerspring mattress brands can vary, but overall they have 64% owner satisfaction when used regularly / everyday. Learn more about innerspring bed owner satisfaction.|
|Durability / longevity||d+||Within three years of ownership, 25%+ of owners who use their innerspring bed regularly / everyday report sagging occurring to an extent that undermines comfort and support. No other mattress type has as high a sagging rate. Learn more.|
|Prices||B||Prices can vary widely – $100 to $2,000+ – mainly due to design and amount / type of material used. The average price for an innerspring mattress (not including innerspring hybrids) is around $930 for a queen, no foundation.|
|Less (back) pain||c||Initially, innerspring mattresses often provide relief from pain, including back pain. Mattress sagging, however, appears to cause pain for about 20% of owners. (See mattresses and pain for general analysis.)|
|General support||B-||The mattresses – at least initially – often provide an above average level of support. Sagging, however, can undermine the ability of the mattress to properly bear the weight of the sleeper.|
|Edge support||B-||Support for sleeping or sitting near the edge of the bed can vary by brand / model but overall tends to be at least average, especially compared to many foam mattresses.|
|Conforming ability||C-||Innerspring mattresses tend to have low to moderate molding-to-the-body and conforming ability. This can result in noticeable pressure points due to less than ideal distribution of a person's body weight, especially as the mattress ages.|
|Firmness variety||B||Brand names such as Serta, Sealy, Simmons offer many firmness options including soft. Off-brands tend to offer only medium and firm.|
|Easy to move on / get up off||b-||Those models with a thick, soft comfort layer have potential to provide some resistance to movement including the changing of positions. Sagging can also impede movement.|
|Motion isolation||c+||Motion isolation refers to how well a mattress absorbs motion and prevents movement made by one person from disturbing another. Motion isolation for innerspring beds can vary from poor to good depending mainly on coil type. Pricier models tend to provide at least somewhat superior isolation than cheaper ones.|
|No noise||c-||Noise problems – squeaking, creaking, clunking, crackling – can range from significant to nearly nonexistent depending mainly on coil type and cover used. Pocket coils, which are common, tend to have few noise complaints. Learn more.|
|Large person friendly||C+||The durability of low-priced innerspring mattresses (under $500 for a queen) tends to not be ideally suited for people 230+ lbs especially over the long term. Large people also tend to report more noise issues and lack of support than lighter people.|
|Small person friendly||B||Models 12 inches or thicker are often too tall for shorter people to allow for easy access. And because smaller people (those under 110 pounds) often do not exert enough pressure on a firmer mattress to result in conforming support, softer models may be best.|
|No initial odor / off gassing||c+||About 8% of 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 foam comfort layer tend to have the greatest off gassing potential. (General analysis: mattress off gassing.)|
|Not a heat trap||B-||About 6% of owners report sleeping hot. Softer models and those with memory foam tend to have the greatest heat trap potential. (General analysis: mattress heat retention.)|
|Good for sex||b||On this issue, owners often like the bounce of the beds, but comfort can be lacking especially on firmer models. See mattresses and sex.|
|Short break in period||B-||Innerspring beds tend to have a shorter break-in period than foam mattresses – with less difference in comfort before and after break in.|
|Easy to maintain||c+||Most models are one sided and no flip. To combat sagging, owners often report rotating (head to foot) their bed at least twice a year.|
|Easy to lift, move, handle||c||The mattresses can weigh 35-140+ lbs with the average queen weighing about 93 lbs. Pricier, thicker models often weigh the most.|
|Warranties||c+||At least 15% of owners say that warranties lack adequate coverage for sagging. Warranty lengths range 5-25 years with 10 years being about average. 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 often 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 at brick & mortar stores and online.|

* partial estimate to estimate
Owner satisfaction for innerspring mattresses appears to be improving in recent years, but the beds overall still rate behind the other mattress types.
Learn more about how innerspring mattresses compare to the other mattress types.
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, air, water). This is mostly due to innerspring beds in general having somewhat worse longevity / durability than the other mattress types.
|Innerspring Mattresses||All Mattresses|
|Owner Satisfaction For Regular / Everyday Adult Use||63%||69%|
|Owner Satisfaction For Temporary / Occasional / Light Use||86%||89%|
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 report the problem which makes sagging the top innerspring mattress owner complaint.
* estimated to be at least 1.5" depth
Innerspring mattresses consist of many assembled parts and many different types of materials. In other words, the mattresses are not simple – especially compared to foam mattresses which often consist merely of two or more layers of foam glued together. This complexity of innerspring mattresses appears to give them a higher likelihood of developing problems, including sagging problems.
In addition, models with thick pillow tops / comfort layers tend to be at least two times more likely to have sagging / compression than those models with a thin / minimal 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.
A lack of (head-to-foot) mattress rotation is not likely a main cause of sagging because many people who report sagging claim to rotate their mattress regularly. A person's weight also does not appear to be the main cause of the problem since many people who weigh less than 170 pounds report sagging.
While most of our innerspring mattress data is based on owner experiences of the past twelve 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 late 1990s and early 2000s 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 / pillow tops.
Our most recent collected owner experience data suggests that the durability of innerspring mattresses overall is improving somewhat. In addition, the number of Better Business Bureau complaints filed against innerspring mattress companies has fallen quite dramatically in the past three years. This suggests improved durability but could also be due to improved customer service or both.
There are seemingly countless coil types, but almost all of them fall under one of the four types below. Each coil type has its own advantages and disadvantages.
1. Pocket. These are individual coils wrapped in fabric and are the most popular and widely used mattress coil type. They provide mostly consistent distribution of support and at least fair motion isolation. Pricier mattresses often feature a more advanced pocket coil design. Consumers seeking a highly "bouncy" mattress may want to avoid this coil.
2. Continuous. This coil type is likely second to pocket coils in popularity and use. A continuous coil system consists of coil rows made of continuous wire that run head to toe. This coil 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 or quiet. In addition, because the system consists of one integrated piece, it tends to provide below average motion isolation making it a less-than-ideal choice for couples.
3. Bonnell / Open. This coil is hour-glass shaped and has a simple design. They are used in mattresses of various price points. Durability is often fair or better, but support is questionable and motion isolation is below average.
4. Offset. Offset coils are sometimes used in mid- to higher-priced mattresses. They are similar to Bonnell coils but have better spring action and support. Some variations have good motion isolation and noise control.
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.
|Continuous||Offset||Bonnell / Open|
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 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 a high-coil-count mattress as this may result in improved support 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 and composition of the comfort layer largely determines the firmness level of an innerspring mattress.
In addition to supportive coils, innerspring mattresses have a comfort layer which can consist of any number of the following materials.
1. Polyurethane (regular) 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 fiber tend to have the most sagging / compression complaints from owners.
3. Gel-infused polyurethane (regular) foam. This foam is used on a limited number of innerspring mattresses and usually in small quantity. The foam is infused with tiny gel beads – beads which are touted to allow the foam to sleep cooler longer than regular foam. The effectiveness and durability of this foam based on owner experiences is undetermined.
4. Memory foam. This material is often present on innerspring-based mattresses – especially hybrid mattresses – and provides softness as well as a contouring and cradling effect. It can be effective in minimizing pressure points and, to a lesser extent, reducing motion transfer. In general, 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.
5. Gel-infused memory foam. It is increasingly common for mid- to higher-priced innerspring-based mattresses – especially hybrid mattresses – to have at least one layer of gel memory foam, that is, foam infused with 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.
6. Graphene-infused or diamond particle-infused memory foam. A small number of innerspring mattresses use memory foam infused with tiny 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.
7. Latex. This material is not widely used. Its purpose is to provide pressure relief similar to that of memory foam. The latex used is often blended latex – a combination of natural and synthetic latex. The durability of latex often used in innerspring mattresses is questionable as it can develop body impressions. The latex may also off gas and act as a heat trap.
8. Mini coils. These coils are usually no more than four inches tall and tend to be pocket coils. They help to provide additional contouring support.
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.
|Regular Foam||Fiber||Gel Regular Foam*||Memory Foam||Gel Memory foam||Latex||Mini Coils|
|Not heat trap||C||A-||B-||D||C||C-||A|
|No off gassing||C||A||C||D+||D+||C-||A|

Innerspring beds with memory foam – especially those models with at least two inches of the material – may also be referred to as hybrid mattresses. These hybrids often have many of the characteristics, pros and cons of innerspring beds. Learn more: hybrid mattress ratings.
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.
Purchase a firm innerspring mattress, that is, one with minimal padding – preferably no more than two inches of padding in the comfort layer. Most mattress brands offer at least one model that meets this criteria. 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.
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.
Consumers who have used this buying strategy tend to report good comfort, durability and money-saving results.
