Best Convoluted Polyfoam Mattress Toppers – Top Picks and Buyer’s Guide

Written by Keith Cushner

Quick Overview

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.

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.

Good For:

  • Side and back sleepers
  • Sleepers in every weight group (light, average, heavy)
  • Back pain sufferers
  • Couples

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 Foam Mattress Topper from DMI is a standout due in part to its affordability. The topper’s 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 DMI 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.

Good For:

  • Side and back sleepers
  • Sleepers in all weight groups (light, average, heavy)
  • Back pain sufferers
  • Those who tend to sleep hot

Convoluted memory foam mattress toppers tend to cradle the body closer than standard polyfoam, making them excellent options for side sleepers and those who frequently experience aches and pains. Best Price Mattress’ Egg Crate Memory Foam Mattress Topper comes in three thickness options to relieve pressure buildup in sleepers across weight categories.

Customers can choose from five memory foam infusions for the topper. Lavender, aloe, and green tea infusions are designed to reduce stress. The bamboo charcoal infusion is meant to reduce allergens and bacteria, and the copper infusion is engineered to absorb and dissipate excess body heat.

Profile options range from 2 inches to 4 inches, offering comfort to most sleeper types. The 3 and 4-inch profiles offer a bit more pressure relief than the 2-inch model. Side sleepers and those with pain in their hips or shoulders see the most benefit from the thicker layers of memory foam. Couples should also appreciate the foam’s ability to isolate and reduce motion transfer. They should notice fewer disturbances from their partner’s nighttime movement.

Six sizes are available: twin, twin XL, full, short queen, queen, and king. Best Price Mattress’ 3-year warranty backs the Egg Crate Memory Foam Mattress Topper.

Good For:

  • Sleepers across weight categories
  • Side sleepers
  • Couples
  • Those with pressure-induced pain in their hips or shoulders

Buying Guide – Shopping for the Best Convoluted Polyfoam Mattress Topper

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.

What is a Convoluted Polyfoam Topper?

Convoluted polyfoam toppers are widely available, and individual models may vary based on the following three factors:

  • Foam type: Standard polyfoam or viscoelastic polyfoam (also known as memory foam) may be used to construct convoluted polyfoam toppers. Memory foam models tend to conform closer and alleviate more aches and pains than standard polyfoam models.
  • Thickness: Most convoluted foam toppers sold today are between one and three inches thick. Some toppers have the same thickness from head to foot, while others are thicker and thinner in certain areas to help distribute sleeper body weight and provide extra cushioning for sensitive areas (such as the head, neck, and hips).
  • Firmness: Convoluted foam toppers range in terms of firmness, but because they are usually used to soften a mattress surface, most fall between Soft and Medium.
  • Size: In addition to standard mattress sizes, some convoluted polyfoam toppers are ‘trimmable,’ meaning that owners can resize them using scissors or other cutting implements in order to reach their desired size.

What Are the Pros and Cons of a Convoluted Polyfoam Topper?

Benefits of using a convoluted polyfoam mattress topper include the following:

  • Low Price: The average convoluted polyfoam topper costs between $10 and $30, making them the least expensive topper type available. By comparison, other average price-points include $100 to $250 for memory foam toppers, $100 to $400 for latex models, and $60 to $100 for fiber toppers (the second-lowest average price-point).
  • Easy to Move: Because they are so lightweight, convoluted polyfoam toppers are fairly easy to adjust and maneuver for most sleepers.
  • No Noise: Like their memory foam counterparts, convoluted polyfoam toppers produce little to no noise when bearing weight. This may be beneficial for sleepers who awaken easily during the night.
  • Motion Isolation: Although they do not absorb and isolate motion as much as other topper types (namely memory foam and latex), convoluted polyfoam toppers minimize motion to some extent, making them suitable for couples who share a bed.
  • Low Maintenance: Convoluted polyfoam toppers typically come in solid one-piece designs that never need to be shaken or fluffed in order to maintain a full shape.

Cons

Some drawbacks of using a convoluted polyfoam topper include:

  • Below-average Durability: Standard polyfoam often develops sagging and indentations after limited use. The average convoluted foam topper will perform for three years or less.
  • Odor Potential: Off-gassing is a chief complaint regarding polyfoam. Many convoluted foam topper owners report unpleasant, lingering smells after unpackaging.
  • Sleeping Hot: Polyfoam retains relatively high levels of body heat from sleepers, which may cause the topper to sleep warm or hot.
  • Inadequate Conforming: Unlike memory foam, convoluted polyfoam offers little to no body conforming. Sleepers who prefer a closely conforming topper should explore other options.
  • Minimal Pain and Pressure Relief: Despite their convoluted design, these toppers do not alleviate pain and pressure to the same extent as other toppers, such as memory foam and latex models.
  • Tough to Clean: Convoluted foam toppers should never be machine washed, so owners need to either spot clean them by hand or have them dry cleaned.
  • Limited Selection: The availability for convoluted foam toppers is moderate at best, and the selection for thickness and firmness settings is somewhat restricted.

Who Should Use a Convoluted Polyfoam Topper?

A convoluted polyfoam mattress topper is considered most suitable for the following groups:

  • People who awaken easily due to noise or motion. Convoluted polyfoam toppers produce minimal sounds when bearing weight, and they isolate motion to a fairly effective extent.
  • People who have a hard time moving heavy objects. Convoluted foam toppers usually weigh less than 20 pounds, making them fairly easy for most sleepers.
  • Topper shoppers on a budget. Convoluted foam toppers have significantly lower price-points than all other topper types.

On the other hand, a convoluted polyfoam topper may not be suitable for the following groups:

  • People who are sensitive to smell, as convoluted polyfoam often emits a fair amount of off-gassing odor that may persist long after the topper has been unpackaged.
  • People who experience pain and pressure in their neck, shoulders, lower back, and/or hips. Convoluted foam toppers offer minimal pain and pressure relief — and some owners claim to experience more pain and pressure after using one.
  • People who tend to sleep hot. Convoluted polyfoam toppers can absorb and trap a significant amount of body heat.   

How Much Does a Convoluted Polyfoam Topper Cost?

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
Convoluted Polyfoam $10-$30
Latex $100-$400
Memory Foam $100-$250
Feather $100-$150
Fiber $60-$100
Wool $150-$300
