Materials Used

The materials used in a mattress affect its feel, support, breathability, and much more. Here’s an overview of key materials in foam and cotton mattresses.

Foam Mattress Materials

Foam mattresses are constructed using various types of foam:

  • Memory foam – Viscoelastic foam that conforms closely to the body for pressure relief. Provides a “hugging” feel.
  • Polyfoam – More responsive and bouncier than memory foam. Provides a balance of contouring and support.
  • Latex foam – Derived from rubber trees. Provides buoyant, responsive support. Naturally cooling.
  • Gel foam – Infused with gel microbeads to help regulate temperature.

Foam layers provide cushioning and minimize pressure points. Many foam beds also include high-density polyfoam transitional layers for added support.

Cotton Mattress Materials

Cotton mattresses contain:

  • Cotton batting – Breathable, moisture-wicking cotton fibers provide a cool, airy feel. Quilted into the mattress top.
  • Innersprings – Steel coils provide bounce and support. Different gauges and coil designs impact feel.
  • Foam layers – Polyfoam provides cushioning atop innerspring. Memory foam was added for pressure relief.

The combination of breathable cotton, bouncy coils, and contouring foam makes for a responsive, well-rounded cotton mattress.

Firmness and Feel

When shopping for a new bed, firmness and overall feel are key considerations. Here’s how foam and cotton compare:

Foam Mattress Firmness

Most foam mattresses rate around medium or medium-firm on the 1-10 firmness scale. However, many models are available in multiple firmness options.

Factors influencing foam mattress firmness include:

  • Foam densityHigher-density foams are firmer and more supportive
  • Foam type – Memory foam is softer than latex or polyfoam
  • Layering – Plush comfort layers make a bed softer overall

By adjusting these factors, foam beds can be tailored from soft (3/10) to ultra-firm (8/10).

Cotton Mattress Firmness

The majority of innerspring and hybrid mattresses rate around medium-firm (6-7/10). However, some models come in multiple firmness levels.

What affects cotton mattress firmness?

  • Coil gauge – Lower gauge coils are thicker and stiffer
  • Coil design – Different coil shapes impact support and feel
  • Comfort layers – Thicker foam layers make a bed softer

Overall, cotton mattresses have a more universally comfortable medium-firm feel sought by most sleepers.

Foam vs. Cotton Feel

In terms of sleeping feel, foam, and cotton differ quite a bit:

Foam feel:

  • Deep contouring and hug
  • Slow response to pressure
  • Resistance but not pushback
  • Moderate ease of repositioning

Cotton feel:

  • Light, breathable cushioning
  • Bouncy, springy response
  • Provides pushback when compressed
  • Very easy repositioning

Which feel you prefer depends on your sleeping position and preferences. We’ll cover how foam and cotton accommodate different sleep positions next.

Pressure Relief and Support

Pressure relief and support are crucial for spinal alignment and reducing aches and pains. Here’s how foam and cotton beds compare in these areas:

Foam Mattress Pressure Relief

All types of foam gently conform to the body to cushion pressure points like the shoulders, hips, and back. Key benefits:

  • Memory foam excels at minimizing pressure due to deep contouring
  • Latex provides gentle support with moderate contouring
  • Polyfoam cushions pressure points while preventing excessive sinkage

By cocooning the body in comfort layers, foam mattresses reduce pressure buildup exceptionally well.

Cotton Mattress Pressure Relief

Cotton mattresses provide pressure relief through:

  • Quilted cotton covers for initial cushioning
  • Polyfoam comfort layers over the coils
  • Memory foam in the top layers of some models

However, cotton beds don’t contour as closely around pressure points compared to all-foam mattresses. The responsive coils bring you back to the surface rather than letting you sink in deeply.

Foam Mattress Support

While initial comfort is a strength, foam beds vary in their supportiveness:

  • Memory foam lacks resilience, allowing heavier areas to sink in too deeply
  • Polyfoam is more supportive thanks to its buoyancy and responsiveness
  • Latex delivers the most balanced comfort and support due to its rubbery elasticity

Zoned transitional polyfoams and ergonomic layering optimize spinal alignment on foam beds.

Cotton Mattress Support

Innerspring and hybrid mattresses excel at providing supportive pushback:

  • Steel coils compress where needed and then spring back into shape
  • Thicker-gauge coils prevent sinkage around the edges
  • Stable coil units minimize motion transfer across the bed
  • Reinforced edges improve support when getting in and out of bed

The dynamic response of cotton beds keeps sleepers lifted and properly supported all night long.

Motion Isolation and Transfer

For couples, minimizing motion transfer across the bed is key for undisturbed rest. Here’s how foam and cotton mattresses compare:

Foam Mattress Motion Isolation

Foam excels at absorbing motion before it travels across the bed’s surface, making it ideal for light sleepers.

  • Memory foam performs the best due to its high density and viscosity when compressed
  • Polyfoam also reduces motion transfer but is moderately bouncier
  • Latex minimizes motion transfer fairly well despite its buoyancy

Overall, all-foam mattresses isolate motion exceptionally well for undisturbed sleep.

Cotton Mattress Motion Transfer

Due to the interconnectivity of steel coils, innerspring mattresses are prone to more motion transfer:

  • Coils transfer movement across the bed as they compress and recoil
  • Quilted covers and foam comfort layers help dampen transfer slightly
  • Continuous coils reduce transfer better than individually pocketed coils

For the least motion transfer, cotton mattresses with foam comfort layers help, but generally can’t match all-foam beds.

Temperature Regulation

Proper temperature regulation allows you to sleep cool and comfortable all night long. Here are some key temperature differences:

Foam Mattress Temperature

Foam mattresses pose some potential downsides for temperature regulation:

  • Closed-cell foams can retain heat around the body
  • Memory foam is prone to sleeping hot for some
  • Gel- and graphite-infused foams offer cooling benefits

However, new formulations like open-cell foams and copper conductivity boost airflow and cooling.

Cotton Mattress Temperature

The breathable materials in cotton mattresses help maintain a comfortable sleep climate:

  • Cotton naturally absorbs moisture and allows airflow
  • Coil cores promote air circulation within the mattress
  • Natural fibers like wool and silk also help regulate temperature

Overall, cotton beds sleep cooler for those concerned about heat retention, especially in warmer climates.

Responsiveness and Bounce

Responsiveness refers to how quickly a mattress reacts to applied pressure, while bounce creates lift and springiness.

Foam Mattress Responsiveness

Foam mattresses differ in their responsiveness:

  • Memory foam slowly conforms to the body with minimal bounce
  • Latex offers more responsiveness and light buoyancy
  • Polyfoam provides moderate conforming with some bounce

Many foam beds feature responsive comfort layers over firmer support foams for a balanced feel.

Cotton Mattress Bounce

Innerspring and hybrid mattresses offer the most bounce and responsiveness:

  • Coil cores compress and then spring back instantly when pressure is applied
  • Offset or pocketed coils maximize bounce and responsiveness
  • Natural fibers like wool and cotton also add lift

Those who like the feel of a traditional spring mattress appreciate the superior bounce of cotton beds.

Edge Support

Proper edge support allows you to sleep close to the sides without the bed collapsing. Here’s how the two mattress types compare:

Foam Mattress Edge Support

All-foam mattresses are prone to excessive sinkage and softness around the perimeter:

  • Softer foam comfort layers compress more easily at the edges
  • Foams lack the internal structure to keep edges reinforced

Reinforced edges and zoned transitional layers help, but foam beds still lag in edge support.

Cotton Mattress Edge Support

The internal coil system provides consistent edge support on cotton mattresses:

  • Coil cores are inherently more stable on the edges
  • Thicker coil gauges around the perimeter minimize sinkage
  • Reinforced edges through extra padding also help

Hybrids and innerspring outperform foam beds for sleepers needing ample edge support.

Ease of Movement

Being able to change positions easily on a mattress helps ensure restful, uninterrupted sleep.

Foam Mattress Movement

Deep contouring foam encourages a “stuck in the mattress” feeling at times:

  • Memory foam conforming makes changing positions harder
  • Polyfoam offers more ease of repositioning
  • Latex resists body impressions better for easier movement

To improve responsiveness, some foam beds add latex layers or zonally-targeted support systems.

Cotton Mattress Movement

The dynamic nature of interior coils makes changing positions easier on cotton mattresses:

  • Innersprings recoil instantly as you move to another area
  • Added foam layers still allow moderate conforming and mobility
  • Zoned support designs facilitate movement in certain models

Overall, the buoyant responsiveness of cotton surfaces makes repositioning effortless.

Sexual Activity

For sexually active couples, responsiveness, bounce, ease of movement, and edge support all contribute to better mattresses for sex.

Foam Mattresses for Sex

The conforming properties of foam can detract from mattresses being optimal for sex:

  • Memory foam lacks responsiveness and makes movement harder
  • Moderate-density polyfoam balances contouring with responsiveness
  • Latex foam provides light buoyancy, bounce, and mobility

To improve intimacy, firmer and more responsive foam or hybrids often work best.

Cotton Mattresses for Sex

The springiness of cotton beds helps sleeping partners:

  • Innersprings generate bounce and facilitate mobility
  • Stable edges allow full use of the mattress surface
  • Quick responsiveness makes moving and changing positions easier

Taken together, these attributes make cotton mattresses highly suitable for sex compared to foam.

Durability and Lifespan

You want your new mattress to provide many years of comfortable sleep before needing replacement.

Foam Mattress Durability

High-quality foam mattresses typically last 7-10 years, though materials impact durability:

  • Polyfoam lasts longer than softer memory or latex foam
  • Higher-density foam resists impressions better over time
  • Reinforced edges prevent premature breakdown

Rotating your foam mattress every 6 months helps prevent uneven wear as well.

Cotton Mattress Durability

On average, expect a high-end innerspring or hybrid mattress to last 6-8 years with proper care. Factors influencing lifespan include:

  • Coil gauge – Lower gauge coils last longer
  • Coil design – Continual coils last longer than individual pocketed
  • Natural fibers – Components like cotton and wool keep resilience

Flipping or rotating cotton beds every 3-6 months helps prevent sagging and improves durability.

Off-Gassing and Smell

Off-gassing refers to the initial smell of volatile organic compounds (VOCs) in new mattresses.

Foam Mattress Off-Gassing

Foam mattresses are prone to more noticeable off-gassing odors:

  • Polyfoam emits the most VOCs and smell
  • Plant-based foams like latex have minimal to no odor
  • Memory foam releases moderate VOC emissions

Allowing your foam mattress to fully air out before use gets rid of any smells.

Cotton Mattress Off-Gassing

Cotton, wool, and other natural fibers produce little to no off-gassing odor:

  • Organic cotton and wool have no VOC emissions
  • Coils don’t emit VOCs either
  • Most smells come from glues in the mattress construction

Overall, cotton mattresses have less of that “new mattress smell” compared to synthetic foam beds.

Maintenance, Protection, and Care

Proper maintenance and care help your mattress last longer. Here are some key points on caring for foam and cotton beds:

Caring for a Foam Mattress

  • Use a mattress protector to shield from spills and stains
  • Rotate foam mattresses every 6 months to reduce wear
  • Vacuum to remove dust and debris from the surface
  • Spot clean stains with an enzyme-based foam cleaner
  • Avoid excessive moisture that could lead to mold or mildew

Caring for a Cotton Mattress

  • Protect with a waterproof mattress protector
  • Rotate or flip cotton beds every 3-6 months
  • Vacuum surface regularly using an upholstery attachment
  • Spot-treat stains immediately with a mild detergent
  • Allow moisture to fully air dry to prevent mold growth
  • Re-tighten loose innerspring coils to maintain support

Consult your manufacturer’s care guidelines for any special maintenance needed.

Choosing Between Foam and Cotton
