Health Benefits Associated with Using Memory Foam

One of the key elements to being healthy is having a good night’s sleep. Without proper sleep and rest, your body can’t operate optimally. There can be a number of reasons for this, but the most common reason is definitely comfort. If you don’t have a comfortable mattress, you will not sleep well.

Memory foam makes a huge difference. With memory foam toppers being a great option to test how memory foam feels to you, and how it improves your sleep.

Some of the other health benefits include:

  • Taking stress and weight off joints
  • Keeping swollen and tired muscles warm
  • Reducing snoring
  • Reducing neck and upper back pain
  • Helping with sleep apnoea

Why a Memory Foam Topper Will Improve Your Sleep

If you have never touched or experienced memory foam, you’ve been missing out. It’s a unique material in many ways, it’s able to mould to your own individual shape, and return to its normal resting shape.

Making it a popular choice with lumbar supports, mattresses, pillows, cushions, and of course mattress toppers. Toppers are perfect if you have a perfectly good mattress that isn’t comfortable enough, or you want to test the material before buying a complete mattress.

How Does Memory Foam Work?

I have covered various types of mattresses and materials before. The main type of mattress filling is springs, or coils. They take the weight of the person laying on them and spring back when not in use. When weight is put on foam however, it absorbs and compresses. Adjusting to the weight and shape of the person and being able to mold to their body shape.

Memory foam can vary in ‘quality’ if you like. The density of the foam determines how well it compresses and deals with weight. The higher the density, the better. Six pounds of density is the highest density, while two pounds is on the lowest end of the scale.

It’s also the material of choice to keep dust mites away and is a better choice if you suffer from any allergies. It’s easy to clean and very strong, so foam has a long life if you look after it.

What’s Bad About Memory Foam?

With so many position points and with me raving about how good memory foam is, what’s the bad points? Nothing is perfect, and memory foam isn’t for everyone. But there are only a couple of real downsides as I see it.

Firstly, it’s more expensive than other materials. Budget always plays a big part in what we buy, so this is a factor for some people. It’s always a tough choice when you’re buying something as important as a topper. What price do you put on a good night’s sleep and your health?

Secondly, foam does hold on to heat more than some other materials. The good news is that a 4” topper is thin enough for this not to be a huge issue. But foam in general can be uncomfortable in summer if you don’t have good ventilation in the room.

Stacking it against the other options on the market it’s still a smart choice. The comfort and support is well worth the extra cost and warmth in my opinion.

What to Look for When Choosing a 4 Inch Memory Foam Mattress Topper

It’s not overly complicated to narrow down the best quality toppers. There are three main areas to look at when browsing the specs of products. This is what I looked at when putting my top 5 together. These are as follows:

Breathable fabric – As mentioned earlier memory foam does tend to hold on to heat. Well-designed toppers with breathable fabric and open cells allow much better air flow. Keeping the core temperature of the foam lower.

Quality – As with all products you want the best possible quality, and value. Always browse the customer reviews and feedback and look at the highest rated products.

Density – This is the main consideration when looking at how the foam will perform. Rule of thumb here is, the higher the density the more comfortable the topper will be.
