    How to Choose the Best Memory Foam Mattress?

    Memory foam was initially invented by NASA to cushion pilots during flights. It was later adopted by the healthcare and sleep industries thanks to its visco-elastic attributes and ability to relieve pressure. Today, memory foam is the most popular mattress material in the UK.

    This memory foam mattress buying guide highlights essential considerations when comparing different memory foam mattress brands in the UK. 

    How to Choose the Best Memory Foam Mattress?

    Tips When Buying Memory Foam

    Traditional Memory Foam vs Gel Foam

    Memory foam mattresses come in 2 major types: traditional and gel-infused memory foam. There is not much difference between these mattresses on the surface. Both types are considered the most comfortable mattresses, thanks to the way they conform to the sleeper’s body to hug its curves. The two also score relatively equal marks when it comes to absorbing motion energy, leading to reduced disturbances. 

    The significant difference between regular memory foam and gel memory foam is in the construction. Essentially, gel memory foam is a traditional visco-elastic foam that has been infused with cooling gel. This material helps to reduce heat build-up- the major issue that affects traditional memory foam. Some brands use Phase-Changing Materials (PCM) to offer similar results. If you fear that memory foam might cause you night sweats, a gel-infused model might be a better proposition. Just be ready to spend a little more. 

    Mattress Density

    Memory foam mattresses come in 3 density options: high, medium, and low. Density simply talks about how much material is used per cubic foot of the mattress. Density in a memory foam bed affects its price tag, durability, and how long it takes to break in. 

    Density also affects the comfort level of the mattress. Generally, low-density memory foam mattresses (3 pounds and under) are best for lightweight people who sleep mainly on their sides or back. Medium-density mattresses (4-5 pounds) make a good bed for average-weight individuals across all sleeping positions. Lastly, high-density mattresses (5 pounds and above) are the best for heavy side, stomach, and back sleepers. 

    Thickness

    Thickness refers to tallness. Memory foam mattresses range between 6 and 14 inches in thickness. In general, a thicker mattress will feel softer than a thinner one leading to more pressure relief. However, note that thicker mattresses tend to be less supportive, although this also depends on its density plus your weight. Ideally, if you’re eyeing a thicker mattress, you also need to ensure that it’s dense enough to support your weight and sleeping style.

    Best Overall: Nectar Mattress

    Definitely, it’s hard to go wrong with the Nectar if you’re looking for a relatively affordable but great quality memory foam mattress. Its medium-firmness makes it a suitable candidate for first-time memory foam buyers who aren’t sure which firmness level will work for them. In addition, its ability to support different sleeping positions makes it a great pick for couples who can’t agree on the best mattress. Lastly, this mattress will make an incredible purchase for a guest room.
