Mattress toppers are individual layers of bedding material that are used to adjust the firmness of a sleeper’s existing bed, as well as provide extra cushioning. A topper may be suitable for someone with an older mattress that has developed indentation marks that undermine sleeper support, as well as those who are dissatisfied with their bed’s firmness and/or thickness. Most toppers measure between two and four inches thick, and are available in sizes that correspond with common mattress measurements.
Convoluted polyfoam, also known as egg-crate foam, is a popular choice for topper material. The term refers to polyurethane foam shaped with ridges to create a contoured (or convoluted) surface that alleviates aches and pains in the sleeper’s most sensitive areas. The foam may be standard polyfoam or viscoelastic polyfoam, which is also known as memory foam. These toppers also isolate motion fairly well and produce no noise when bearing weight. Convoluted polyfoam toppers tend to be much cheaper than those made from other materials, making them a high-value option. In addition to bedrooms, they are commonly used in guest rooms, dorm rooms, and hospitals.
Read on to learn more about convoluted toppers, including shopping tips for first-time buyers. Below you’ll find our picks for the best convoluted foam toppers sold today. Our choices are based on verified customer and owner experiences, as well as intensive product research and analysis.
A common complaints about convoluted foam toppers is lackluster support; the toppers tend to sag beneath the shoulders, waist, and other areas where weight is concentrated. Our Editor’s Pick, the 5-Zone Contour Comfort Memory Foam Topper from Beautyrest, is a standout because of its innovative design. The topper is divided into five separate zones, each with different contour shapes, to provide tailored support for the head, shoulders, back, waist/hips,and legs. The zoned construction can also help minimize tossing and turning during the night.
The memory foam conforms to a noticeable extent but the topper is considered ‘Medium’ in terms of firmness and it won’t sag excessively. The topper also isolates motion fairly well and produces no noise when bearing weight, making it suitable for couples. Its 3″ thickness profile also makes it a great option for side and back sleepers who weigh 130 pounds or more.
Our Runner-Up Pick is the Egg Crate Foam Topper from Cardinal & Crest, which is made from standard polyfoam with a ‘Medium’ firmness. This material offers close conforming and great pressure relief; comparatively, many other standard foam convoluted toppers do not provide the same level of comfort and support. This topper is also more durable than most models made from comparable foams; the expected lifespan is at least two years.
Other key strengths of this topper include exceptional motion isolation and no noise. Another advantage is size selection; while many convoluted foam toppers are limited in sizes, this one is available in Twin, Full, Queen, King, and California King sizes. At 3″ thick, it will be most suitable for side and back sleepers in the average weight (130 to 230 pounds) and heavy weight (more than 230 pounds) groups. The Egg Crate Foam Topper from Cardinal & Crest is backed by a full customer satisfaction guarantee.
Medical supplies companies manufacture many of the convoluted foam toppers sold today because of their wide use in hospitals, nursing homes, and other medical/long-term care facilities. These models tend to offer the best pain and pressure relief for sleepers. The Convoluted Foam Mattress Topper from Duro-Med is a standout due in part to its thickness; at 4″, it is particularly suitable for heavier sleepers.
The topper is also ‘Medium Soft,’ making it less firm than many convoluted topper models and a great option for lighter individuals. As a result, the Duro-Med Convoluted Foam Mattress Topper can accommodate sleepers in any weight group. This topper sleeps fairly cool, as well; many sleepers complain that convoluted foam toppers sleep excessively warm. It is available in smaller sizes designed for hospital beds, as well as Full, Queen, and King options.
Polyfoam is not particularly breathable or conducive to good air circulation, causing most convoluted foam toppers to sleep warm. The Convoluted Gel Swirl Memory Foam Topper from Linenspa addresses this problem nicely. The gel-infused, open-cell memory foam does not retain as much body heat from sleepers and will maintain a comfortable temperature throughout the night for most. The memory foam also conforms and alleviates aches and pains to the same extent as many non-convoluted memory foam toppers.
Size selection is another benefit. The topper is available in two thickness profiles, 2″ and 3″, to accommodate most sleepers regardless of their weight group. Both options offer the same ‘Medium’ firmness, but the 3″ topper will hug the body more closely. It also comes in six sizes – Twin, Twin XL, Full, Queen, King, and California – making it suitable for the vast majority of mattresses sold today. The Convoluted Gel Swirl Memory Foam Topper is backed by a three-year warranty; comparatively, most convoluted foam toppers do not come with any sort of warranty coverage.
The term ‘mattress topper’ refers to a separate layer of cushioning that can be placed on top of a mattress for added softness, comfort, and support. Some toppers rest freely on the uppermost part of the mattress (known as the comfort layer), while others are tucked under the top sheet. Toppers are available to accommodate all standard mattress sizes; the topper is slightly smaller than the mattress itself, allowing it to fit more easily beneath the topsheet.
Some toppers are made from convoluted polyfoam. Also known as egg-crate foam, convoluted polyfoam is made using chemical-treated polyurethane. The foam is convoluted, or contoured, to help alleviate pain and pressure points in sensitive areas of the sleeper’s body, such as the neck, shoulders, lumbar (lower back), and hips. However, some sleepers may prefer to sleep on the topper with its convoluted side facing downward.
Convoluted polyfoam toppers are widely available, and individual models may vary based on the following three factors:

The average convoluted polyfoam topper costs between $10 and $30, and most models will not cost more than $50. This average price-point is the lowest among all toppers. The graph below compares price-points for the six most common topper types.
|Topper Type||Average Cost|
|Criteria||>Polyfoam Topper Rating||Explanation|
|Thickness Selection||Fair to Good||Convoluted polyfoam toppers generally range in thickness between one and three inches. Those seeking a thicker topper may want to consider other types.|
|Durability||Poor to Fair||Standard polyfoam deteriorates somewhat quickly, and convoluted foam toppers have an average lifespan of three years or less.|
|Support||Poor to Fair||According to owners, convoluted foam toppers do not improve the supportiveness of a mattress very effectively.|
|Conforming||Poor to Fair||Convoluted polyfoam does not conform much (if at all), and those seeking a closely conforming topper may want to consider memory foam or latex.|
|Pain/Pressure Relief||Fair to Good||Some convoluted polyfoam toppers alleviate pain and pressure in sensitive areas, but most models do not offer the same level of pressure and pain relief as memory foam or latex toppers.|
|Motion Isolation||Good to Very Good||Convoluted polyfoam absorbs and isolates motion fairly well, which can reduce nighttime disruptions for couples whenever one person gets into/out of bed or shifts positions.|
|Noise||Very Good to Excellent||According to owner feedback, convoluted foam toppers produce little to no noise when compressed.|
|Temperature Neutrality||Poor to Fair||Convoluted polyfoam tends to sleep hot, and may not be suitable for people who already sleep hot or warm on their own.|
|Odor||Poor to Fair||Convoluted polyfoam toppers tend to produce a fair amount of odor when removed from their packaging, and these smells can linger.|
|Sex||Fair to Good||Convoluted polyfoam is often responsive enough for sex due to its lack of conforming, but the material may not be bouncy enough for some.|
|Ease of Moving||Very Good to Excellent||Most convoluted foam toppers weigh less than 20 pounds, making them fairly easy to move and adjust during the night.|
|Ease of Cleaning||Poor to Fair||Convoluted foam toppers typically need to be spot cleaned by hand or dry cleaned, and should never be machine washed. This can make them somewhat expensive and/or time-consuming to keep clean.|
