What is Memory Foam?

A little history for those who are new to memory foam. It was actually invented by scientists at NASA. The medical industry started to realize there were a lot of practical health benefits to using memory foam.

It’s soared in popularity and you can commonly find memory foam being used in pillows, mattresses, back supports, mattress toppers, and more.

When weight is placed on memory foam it moulds with the shape of the weight. So, when used in mattresses it moulds with the contours of your body when you lie on it. Much more effective at supporting your joints than coil springs.

Why Should You Choose a Memory Foam Topper?

Memory foam is a popular choice for a topper because it’s a very comfortable material. Within a few inches of a topper there are few materials that can offer so much support and comfort.

This material is known to help promote natural spine alignment, relieve pressure on joints, help to reduce swelling and rehabilitate injuries, and more.

When compared with other filling materials this means less aches and pains, less disruptions to your sleep, and more rested muscles. It’s even known to reduce snoring in some cases.

If your partner needs convincing as the topper is going to cover their side as well, just let them know that memory foam reduces motion transfer. That means they will not feel the movement when you’re turning in your sleep.

How to Choose a Mattress Topper

There are a few things to look out for when choosing a topper. Here are some of the most important areas to consider:

Thickness – In this article I’m looking at 3” toppers. This is middle of the road and is probably the sweet spot for comfort and price. There are also 2” toppers and 4” topper options available that may be better for your budget and level of comfort.

Ease of Cleaning – Memory foam is naturally inorganic and resists dust mites. Look for a topper with removable covers so you can wash or spot clean the covers and protect the foam.

Heat Transfer – One of the drawbacks to memory foam is its ability to retain heat. If you want cooler options, look for open cell foam for added ventilation.

Density – The density of the memory foam is an indication how much support it will provide. There is a numerical scale, with six being a really high density.

Sleepkings 3” Memory Foam Topper with Cover

Sleepkings 3” Memory Foam Topper with CoverThis 7.5cm/3” memory foam topper from Sleepkings comes complete with a soft knitted removable cover. Memory foam needs to be protected, so covers are a must for me. It means you can surface clean stains easily, and put the cover through a machine wash if necessary.

There are elastic straps to help hold the topper in place. Just simply lay it on top of your existing mattress and secure it. You will notice a huge improvement in the support and comfort when you lay down on it.

It’s made from 100% Visco elastic memory foam. This foam is commonly used in toppers and is a good quality foam that performs really well and lasts a long time. It’s a soft to medium feel, but as explained above, memory foam works with the weight and contours of your body to offer support that can’t be matched by many other bedding materials.

Southern Foam 3” Memory Foam Topper

Southern Foam 3” Memory Foam TopperI’ve owned a couple of Southern Foam products before and confirm they are really good quality. This 3” is a great way to change the feel of your existing mattress completely at a fraction of the cost of buying a memory foam mattress.

It’s made with 40kg UK made memory foam. This is a high-density foam and can help with muscle and joint pains by moulding around the shape of your body and giving you superb support as you sleep.

It’s available with or without a washable outer cover. I always recommend buying a cover as it will extend the life of the topper and make cleaning it a lot easier. But it’s up to you, at least you get the choice.

Littens 3” Egg Shell Profile Memory Foam Topper

Littens 3” Egg Shell Profile Memory Foam TopperThe unique egg shell profile on this topper from Littens gives it an interesting and different feel. The main advantage with this profile is the increased airflow to help keep you cool.

One of the drawbacks to memory foam is that it retains a lot of heat and can be uncomfortable if you get too hot while sleeping. So, this is definitely one for the hot sleepers to take a close look at.

It has anti-dust mite and hypoallergenic properties as you would expect from a quality memory foam. It’s also manufactured here in the UK, always nice to support locally manufactured items.

It’s a high-density Visco memory foam. Just place it on top of your existing mattress and you will have a new feel to your old bed. The 3” (7.5cm) of foam is more than enough to give you a complete memory foam experience.

LANGRIA 3” Memory Foam Topper with CoverThis 3” topped from LANGRIA will give your old mattress a new lease of life with a layer of memory foam that will work with the contours of your body. This support means fewer aches and pains, you can resolve back ache, neck strain, and more.

The topper comes with a 100% polyester cover that’s breathable, nice and soft to the touch, and machine washable. It has a knitted inner cover and will protect your foam to keep it at its’ best for longer.

The topper is compressed and folded to make it easier to transport. You’ll need to unfold it and leave it for around 24 hours to expand to its intended size and shape. There may also be a ‘gassing out’ period as with most memory foam products. The odor is non-toxic and will disappear within a few days.

You have the option to buy it with or without a cover. If you’re using this topper every night on top of your mattress I recommend having the cover to maximize its life and help you clean it.

The foam is 40kg which is pretty standard for toppers. It’s a soft to medium feel and offers decent support. It’s made in the UK and meets all of the rigorous quality standards and regulations.

It will take a day or so to roll out to its full size and for the chemical odor to leave the topper.
