What’s In Your Mattress?

Many people don’t realize that there are an array of different mattress foams out there, each of which can uniquely impact your sleep. Foams can vary in price, firmness, sustainability, and much more. So whether you’re on a budget or looking for the most relaxing material, we have analyzed the benefits of each foam so you can find that perfect mattress sooner, rather than later... You’re welcome.

Polyurethane Foam (PU Foam)

Polyurethane Foam, most commonly known as PU foam, is the most common type of foam found in mattresses. PU foam has similar qualities to memory foam but it’s more affordable. It can help improve spinal alignment, has great pressure relief, is resistant to liquids or spills, and is great at blocking out halogens and dust mites. PU Foam can range in quality so it is important to find a balance between affordability and high-quality material. Consider looking for higher-quality PU foams, like those found in OkiOki mattresses, if you want a longer-lasting and affordable mattress.

Memory Foam

Memory foam is a great option if your goal is to reduce joint stress while you sleep. Mattresses with memory foam are “fluid” and have the capability of quickly conforming to your body at specific pressure points. If you have allergies, you should consider memory foam for its hypoallergenic properties. There are three main types of memory foam:

  • 1. Traditional Memory Foam
  • Traditional memory foam has been around since the ’90s and many have benefited from the comfort and tension relief that it provides. However, the most common complaint with traditional memory foam is heat retention. If you tend to get hot while you sleep, you may want to consider another type of memory foam.


    2. Open Cell Memory Foam

    The differentiator of open cell memory foam is that it has microscopic holes (like swiss cheese) throughout its material. This helps the mattress conform to your body much faster, and it reduces issues of overheating.


    3. Gel Memory Foam

    The main purpose of gel memory foam is to provide the coolest night’s sleep possible. It is just like traditional memory foam but houses tiny gel molecules throughout. Despite the hype, there are still some heat retention issues with this type of foam. Your best bet with any memory foam mattress is always to add a cooling cover.


    Reflex Foam

    Reflex foam is a cheaper alternative to memory foam. Instead of using holes in the material, reflex foam utilizes bubbles throughout to give a similar feel to memory foam. Since it is naturally more firm than memory foam, reflex foam mattresses can be better for back support and spinal alignment. If you’re looking for a memory foam feel without a memory foam price, reflex foam mattresses may be something to consider.


    Latex Rubber Foam

    If sustainability is important to you, then you should look into a latex rubber foam mattress. Latex rubber is made from a natural sap that comes from trees, making it one of the few renewable resource mattresses. The sap is extracted, placed in a mold, and is then vacuumed to remove any air bubbles. It’s important to note that latex rubber mattresses are usually bouncier than a typical mattress and often less dense.


    Convoluted Foam

    Also known as “egg crate foam,” thanks to its shape, convoluted foam is abundant and can mostly be found in mattress toppers. The shape of the mattress allows for better heat distribution and pressure relief. Egg crate mattresses are very budget friendly, however, it is important to know that they are usually not enough on their own. In order to get the best support, you will most likely need to have another mattress underneath. Also, if you are sensitive to certain materials, you should be aware that convoluted foam is not considered “medical-grade” and may cause allergen issues.


    Graphite Foam

    Yes, you read that right. Graphite is actually infused into certain types of foams because of its natural benefits. Temperature issues that arise in typical foams aren’t an issue in graphite foam. Thanks to graphite’s unique molecular structure, heat is dispersed much faster in mattresses with graphite than in those without it. Graphite foam technology can be found in the OkiFirm and the OkiFlex mattresses.
