Polyurethane Foam (Top 4 Pros & Cons)

Polyurethane foam is a type of soft, cushiony material often used in mattresses, furniture, and pillows. It is a synthetic material made by combining two main ingredients: polyol and diisocyanate, and oftentimes, some other chemicals are added to reach a desired texture. When these chemicals react together, they expand and form a foam structure. It’s commonly used in mattresses, furniture cushions, insulation, and even car seats. Think of it like a sponge, but made from chemicals, that can be squished and will bounce back to its original shape.

Pros

  • Affordable:  One of the primary advantages of polyurethane foam is its cost-effectiveness. Products made from this foam tend to be more budget-friendly compared to those made from materials like natural latex or high-density memory foam.
  • Lightweight:  The foam is relatively light, which makes products like mattresses and cushions easier to handle and move.
  • Common Usage: Due to its adaptability and cost-effectiveness, polyurethane foam is widely available in most bed stores. Polyurethane foam can also easily be produced in various densities and firmness levels, catering to a wide range of sleepers.
  • Good Insulation: The foam provides decent insulation properties, making it a popular choice for people living/sleeping in cooler climates or those who are specifically looking for warmer bedding.

Cons

  • Durability Issues:  Polyurethane foam, especially the lower-density types, can break down faster than other materials like latex or high-density memory foam. This can lead to sagging and reduced support over time.
  • Off-Gassing:  Polyurethane foam can release volatile organic compounds (VOCs), especially when new. This can result in a chemical smell and, in some cases, may cause respiratory issues or allergic reactions in sensitive individuals.
  • Heat Retention: This foam tends to have a poor thermal capability meaning it can trap body heat, making it less comfortable for hot sleepers.
  • Environmental Concerns: The production of polyurethane foam involves chemicals that can be harmful to the environment. Additionally, it’s not biodegradable, raising concerns about its long-term environmental impact.

Memory Foam (Top 4 Pros & Cons)

Memory foam is a type of polyurethane foam that has been modified with additional chemicals to enhance its viscosity and density. It’s often referred to as “viscoelastic” polyurethane foam. Memory foam is often celebrated for its contouring properties. It’s the material that “remembers” your body shape, cradling you as you sleep. Originally developed by NASA in the 1960s for airplane seat cushioning, memory foam has since become a popular material for mattresses, pillows, and various other cushioning applications due to its unique properties.

Pros

  • Contouring:  Memory foam is best known for its ability to contour closely to the shape of an object. When you press your hand into a memory foam pillow or mattress and then lift it away, you’ll notice the foam slowly returns to its original shape. This contouring ability allows it to mold to the shape of a sleeper’s body, offering tailored support and pressure relief.
  • Motion Isolation:  Another notable feature of memory foam is its ability to absorb motion. This means that if one person moves or gets out of bed, their partner is less likely to be disturbed, making it a popular choice for couples.
  • Temperature Sensitivity: Memory foam responds to heat and pressure. When exposed to body heat, it becomes softer, allowing for that signature “sinking in” feeling. Conversely, in cooler environments, it tends to feel firmer.
  • Hypoallergenic: Memory foam is dense, which can make it less hospitable to dust mites and allergens compared to some other mattress materials.

Cons

  • Heat Retention:  Traditional memory foam is known to retain body heat, which can make the mattress feel too warm for some users.
  • Off-Gassing:  Just like normal polyurethane foam mattresses, new memory foam products can also release volatile organic compounds (VOCs), leading to a distinct chemical smell. While this odor usually dissipates within a few days to weeks and is generally considered harmless, it can be off-putting to some users.
  • Slow Response Time:  Memory foam can take time to adjust to changes in pressure, leading to a “sinking” feeling that some users dislike. This can also make it slightly more challenging to move or change positions.
  • Potential for Sagging: Over time, especially with lower-quality foams, memory foam can sag or develop indentations where the user sleeps.

Natural & Organic Latex (Top 4 Pros & Cons)

Latex is a milky, elastic substance derived primarily from the sap of the rubber tree. The sap is harvested by tapping into the tree, processed, and then transformed into a foam-like structure using one of two primary methods: Dunlop or Talalay. The Dunlop method results in a denser and heavier latex, while the Talalay method produces a softer, more consistent, and breathable latex. It’s known for its elasticity, and resilience, and is used in a variety of products, from medical gloves and balloons to mattresses and car tires.

Pros

  • Eco-Friendly: Natural latex is a renewable resource and is biodegradable, making it an environmentally friendly option and a sustainable choice.
  • Durable and Elastic: Known for its longevity, a latex mattress can last up to 20 years or more. Latex is also highly elastic, allowing it to stretch without breaking and then return to its original shape. In products like mattresses or pillows, latex offers a unique combination of support and cushioning, often described as a buoyant feel.
  • Breathability: Natural latex tends to be more breathable than many synthetic foams, which can help regulate temperature and reduce heat buildup. This means it does not retain heat like its foam counterparts, ensuring a cooler sleep.
  • Hypoallergenic:  Natural latex has inherent properties that make it resistant to dust mites, mold, and certain bacteria, which can be beneficial for those with allergies. Additionally, when opting for organic latex, there’s little to no off-gassing.

Cons

  • Weight: Latex mattresses tend to be heavier, which might be a consideration when moving or rotating.
  • Price: High-quality latex mattresses can be more expensive initially, but their durability often means long-term savings.
  • Latex Allergy: Some people are allergic to proteins found in natural latex, which can cause reactions ranging from skin irritation to more severe allergic responses.
  • Resistance to UV: Latex can degrade when exposed to prolonged direct sunlight. However, this is easily preventable by keeping your mattress covered, out of direct sunlight (UV damage), and using a mattress protector! Most people won’t suffer from this issue unless their latex is out in the open sun for a prolonged period of time.

Choosing between latex, memory foam, and polyurethane foam ultimately boils down to personal preference and individual sleep needs. By understanding the distinct characteristics of each material, you’re better equipped to make a choice that ensures restful nights for years to come. Remember, a mattress is an investment in your well-being, so take the time to select one that aligns with your comfort and health priorities. Happy sleeping!

About Our Natural Bamboo Covers

Why do you offer 2 covers for this size?

We are always looking for ways to improve our environmental impact, which is why we switched to our new Organic Cotton Covers as soon as we could – but it meant we have some very good quality stock leftover. Rather than put it to waste, we decided to offer it at a small discount to those who want it. Further, due to worldwide shortages and container delays, we may run out of stock of our Quilted covers, and may only be able to offer other covers for some sizes.

How is the ‘Bamboo’ cover different?

The main difference is our Cotton covers are made of 100% Certified Organic material, although our Bamboo covers were still sustainably sourced and 100% Natural. Both covers feel the same on the latex (acting as a minimal comfort layer to protect and hold the latex in place), both have zips on 3 sides and both are cold-machine washable. However, the Bamboo cover is more stretchy, so it can actually be a little easier to put the mattress together. And you can always switch to a Cotton cover later if you wish, which we would do for half-price (Queen $240 $120 or King $290 $145). Thanks for your support!

Save $50 per Base or Mattress

It’s simple: Buy 2 or more bases and/or mattresses, and you’ll save an EXTRA $50 on each one!

For example, bundle any base with any mattress to save $100 instantly. Note: The same applies to just 2 bases, just 2 mattresses, or multiples of each one. Discount applies automatically. Happy sleeping!
