Best 5 memory foam pillow informations: Traditional (or viscoelastic) memory foam is the most widely available variety of the material. It is polyurethane-based, and categorized as a type of polyfoam. Plant-based memory foam is manufactured using a combination of petrochemicals and botanical ingredients. Plant-based foam layers are designed in an open-cell configuration, making them more breathable and cooler for sleeping than standard memory foams. Mattress cover: The top cover — located above the comfort layer — will also vary in its thickness, as well as the material used to make it. Covers that are thicker or constructed from less breathable materials may cause you to sleep hot, and also may affect the responsiveness of the memory layer.
Casper’s latest offering to the UK market – and its most expensive yet – has already proven a hit in America. Combining its now legendry foams with a base layer of springs, you get instant sumptuousness (from the moulding of the four foam layers around your body) coupled with added bounce and airflow (from the pocket coil springs). We were impressed before we even got it out of its vacuum pack – how can those springs be so compressible? (Nearly five years of research, is the answer from Casper.) But that was nothing compared to our excitement over the immediate comfort. The fact that it’s noticeably softer than other Casper mattresses might not be for everyone, though, and made us surprised that Casper claims it’s the brand’s “most supportive mattress yet”. You should also be aware the extra bounce means your partner is more likely to feel it when you turn than with a pure foam mattress. But neither put us off this mattress that feels as indulgent as – if not more than – others two or more times its price.
Initially developed by NASA researchers in the 1970s, memory foam is today one of the most popular comfort layer materials on the market. Memory foam is also commonly known as ‘viscoelastic polyurethane foam’ or ‘low-resilience polyurethane foam (LRPu)’. However, it’s important to note that not all memory foam mattresses are strictly polyurethane-based (see next section for more details). In addition to mattresses, memory foam is also commonly found in pillows and mattress toppers. Memory foam bridges the gap for mattress comfort layers. It combines the low cost and shape retention of traditional polyfoam with the superior support and body-contouring of a latex comfort layer. An important characteristic of memory foam is that it is viscoelastic, meaning that it changes shape when pressure is applied, and then returns to its original form once the pressure is released.

Therefore, the foam creates a mold around the shape of your head, neck, shoulders, ears and any other body part which it comes into contact with when it comes to sleeping on bed pillows. The traditional and most common type of foam is polyurethane, also known as viscoelastic foam. There is also another variant which includes a portion of gel, but this type has thousands of small gel beads in its mix.. Pros and cons of memory foam : Foam isolates and absorbs motion transfer to help couples reduce nighttime disruptions. Off-gassing potential is high for memory foam beds, and some mattresses emit odors for weeks after they are removed from their packaging.
Pressure Points: Memory Foam is designed to contour to the unique shape of your body to help support your head and neck. They provide even support for the neck and head. The foam reforms less where it does not need to, and more where the stress is increased. This allows for uniform pressure on all areas of the head and neck, eliminating pressure points. Hygienic and Hypoallergenic: Memory foam is a synthetic material. It was originally developed for NASA in 1966 to improve sleeping conditions in shuttles. Memory foam products are safe and nontoxic. Memory foam pillows are naturally hypoallergenic inhibiting the growth of bacteria, mold, fungus and dust mites. This is an advantage for those with allergies to dust mites, feathers, or other natural pillow materials.
