What You Need To Know

THE GOOD. Innerspring mattresses are the most popular mattress type mainly for five reasons: 1) consumer familiarity, 2) wide availability, 3) affordability, 4) many firmness and comfort options, 5) suitability for sex.

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-at-best relief for pain and pressure points. 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 called memory foam hybrids – and they are rated separately.

Innerspring Mattress Ratings: Overall As a Group

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, about 25% of owners report sagging occurring to an extent that undermines comfort and support. No other mattress type has as high a sagging rate. Learn more.
General support B- Support level can vary considerably; more expensive models often provide better support. Coil count, coil gauge and coil type largely determine support level. Sagging often undermines support.
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.)
Conforming ability C- Innerspring mattresses tend to have fair-at-best conforming or molding-to-the-body ability. This can result in noticeable pressure points due to less than ideal distribution of a person's weight. More.
Easy to move on b- Those models with poor support or a thick, soft comfort layer may 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 considerably depending mainly on coil type. Pricier models tend to provide superior isolation.
Edge support B- Support for sleeping or sitting near the edge of the bed can vary by model but overall it tends to be at least average – especially compared to many foam-based mattresses.
No initial odor / off gassing B- 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- Owners often like the bounce of the beds, but comfort can be lacking especially on firmer models. See mattresses and sex.
No noise c- Noise – squeaking, creaking, clunking, crackling – can range from significant to nearly nonexistent depending mainly on coil type and cover. Pocket coils tend to have few noise complaints. Learn more.
Large person friendly C+ The durability of low-priced models (under $500) 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. (See mattress guide for large people.)
Small person friendly B Soft innerspring mattresses are widely available. They are often preferred by people under 130 lbs because they better conform to their bodies. Models 12 inches or thicker are often too tall for shorter people to allow for easy access. (See mattress guide for small people.)
Short break in period B- Innerspring beds tend to have a shorter-than-average 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 often weigh 35-140+ lbs with the average queen weighing about 93 lbs. Pricier, thicker models often weigh more.
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.

What Makes Innerspring Mattresses Different

Two characteristics most distinguish innerspring mattresses from other mattress types: bounce and limited conforming ability.

Bounce

Innerspring mattresses tend to have more bounce than other mattress types. This means that quickly placing weight on the mattress, such as sitting down on it, will cause the mattress to rebound, usually 3 to 5 times before stopping. Some innerspring mattresses are bouncier than others due mainly to the type of innerspring coil used.

innerspring bounce comparison

Bounce has a main pro and a main con:

Bounce PRO Bounce CON
At least some mattress bounce is often preferred for sex as it may help to create and maintain rhythm. More. Sitting down on, getting up off, and vigorously moving on an innerspring mattress will produce at least some bounce, and this movement may disturb another person on the bed. Models with pocket coils tend to produce the least disturbance.

Limited Conforming Ability

Innerspring mattresses tend to not conform strongly. In other words, they tend to not contour and mold to a sleeper's body nor envelop and "hug" a sleeper to the extent of most other mattress types. Some innerspring mattresses are more conforming than others due mainly to the type of comfort layer material used.

innerspring conforming comparison

Limited conforming ability has two main pros and one main con:

Limited Conforming Ability PROS Limited Conforming Ability CON
Being less enveloped or "hugged" by the mattress often results in more airflow around the sleeper which helps to keep bothersome heat retention minimized.

Limited conforming ability tends to allow for easier body movement, namely changing positions and getting up off the bed.
Due to the mattress not strongly conforming to the curves of a person's body, a person's weight may be unequally distributed on the mattress. Unequal weight distribution can result in gaps in support and therefore a greater likelihood of experiencing pressure points and even poor spinal alignment.


Price Comparison

Innerspring mattress prices can vary widely – $100 to $2,000 or more – mainly due to design and amount / type of material used. The average price for an innerspring mattress (no foundation) is about $930 for a queen. The price of the average mattress is about $1550.

Innerspring Mattress Owner Satisfaction

Innerspring Vs Other Mattress Types

Owner satisfaction for innerspring mattresses appears to be improving in recent years, but the beds overall still rate behind the other mattress types.

innerspring vs other bed types

Learn more about how innerspring mattresses compare to the other mattress types.

Satisfaction By Year of Ownership

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.

Satisfaction For Temporary vs Regular Use

  Innerspring Mattresses All Mattresses
Owner Satisfaction For Regular / Everyday Adult Use 63% 69%
Owner Satisfaction For Temporary / Occasional / Light Use 86% 89%

Innerspring Mattress Longevity

Innerspring mattresses have lower longevity / lifespan than most other mattress types due mainly to their higher sagging rate (see next entry).

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 report the problem which makes sagging the top innerspring mattress owner complaint.

** partial estimate


Causes of Sagging

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 180 pounds report sagging.

Don't make 'em like they used to?

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 between 1995 and 2005 innerspring mattress durability / longevity took 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.

Some Improvement

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.


Innerspring Mattress Coil Types and Comparison

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 likely the most 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 average at best.

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.

Coil Type Comparison

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 somewhat.

Coil Count and Coil Gauge

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 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, heavy people especially may want to consider buying a high-coil-count mattress as this may result in improved support 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 an innerspring mattress.

Coil gauge may somewhat affect mattress durability / longevity. Mattresses with a lower (thicker) gauge tend to have a longer lifespan than mattresses with a higher (thinner) gauge. Heavy people especially may want to consider buying a mattress with a lower gauge.


Innerspring Mattress Comfort Layer Materials and Comparison

In addition to supportive coils, innerspring mattresses have a comfort layer which can consist of any number of the following materials.

Comfort layer 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 or cotton is often used to provide softness. Durability is questionable as 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 which tends to allow the foam to sleep cooler longer than regular foam.

4. Memory foam. This material may be present on innerspring mattresses in small quantity. (If two or more inches are present then the mattress is often considered to be a memory foam hybrid.) Memory foam provides softness as well as a contouring. 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 retain heat and off gas.

5. Gel-infused memory foam. This foam is memory foam infused with tiny gel beads. It is sometimes used on innerspring mattresses in small quantity. (If two or more inches are present then the mattress is often considered to be a memory foam hybrid.) It tends to reduce heat trap complaints by about 30% compared to regular memory foam.

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.

Hybrid Mattresses

Innerspring mattresses with memory foam – especially those models two inches or more of the material – may also be referred to as memory foam hybrid mattresses. They tend to have characteristics of both innerspring mattresses and memory foam mattresses. Learn more: memory foam hybrid mattress ratings.


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 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. The thicker the topper is, the softer (and perhaps less supportive) it tends to make the mattress.

The advantage of this buying strategy 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.
