Qualities Of Memory Foam

Now that we know what memory foam actually is, we can move on to how it feels, and what sleeping on a memory foam mattress is like. In general, there are three main characteristics describe memory foam mattresses as a whole, though different mattresses will offer varying levels of each of these qualities

  • Contouring: One of the hallmark characteristics of memory foam is right there in the name. When you lie down on a memory foam mattress, you can feel the sleep surface contour specifically to the curves and angles of your body.
  • Sink: In addition to contouring, memory foam tends to have a sink to itthat is, the feeling of being embraced by the mattress, and even of sinking down into it.
  • Palpable Response: As mentioned above, memory foam is extremely adaptive to pressure, and you can feel the material becoming more pliable and less viscous in response to the pressure and heat of your body when you lie down.

Is Memory Foam Good For Allergies

Certain memory foam and sprung mattresses can worsen allergy symptoms, but it all depends on the style of mattress you get. Certain fabrics and materials can be susceptible to build ups of moisture, mould, bacteria, and dust, all of which provides an ideal environment for dust mites, one of the most common household allergens. Thats why its important to find a good memory foam mattress with hypoallergenic features designed with allergy sufferers in mind.

All Dormeo memory foam mattress covers are infused with a CleanEffect® treatment, offering anti-bacterial and anti-dust mite protection, ensuring your mattress stays clean and odour-free for a healthier nights sleep.

As well as providing deep comfort, Dormeo mattresses are also designed to be breathable, allowing moisture such as perspiration to evaporate into the air instead of remaining in the mattress.

Why Is Temperature Important To Sleep

Studies have shown that humans tend to sleep better in cooler temperatures, with the ideal range for adults being between 60 and 67° F.

Our sleep cycle is regulated by our circadian rhythm, which is based on the light and dark cycle of the sun and takes its cues from environmental and personal factors. Whilst our core body temperature is around 98.6° F , it fluctuates by about 2° in the night.

Body temperature starts to drop around two hours before sleep, which triggers the release of melatonin, the sleep hormone. And during sleep, body temperature continues to fall.

So if your bedroom is too warm your temperature will not start to fall. This affects not only sleep onset, but also sleep quality, your amount of unbroken sleep, and time spent in different sleep stages.

This leads to grogginess and, over time, can negatively impact your immune system, memory, and even lead to specific health conditions.

Support Of The Natural Curvature Of The Spine

So, no matter how you move around your mattress when sleeping, you will get the support you need to maintain your natural body shape. That means you will have fewer back problems and other issues that arise from poor posture when sleeping. Your body is almost perfectly supported, and your spine is kept straight if you sleep on your side, and maintains its natural S-shaped curvature if you sleep on your back.

If you sleep on your belly, a memory foam mattress gives you support where you need it. You dont want your belly squeezed flat on a hard spring mattress. Memory foam softens and allows your belly to sink into it while maintaining support for the lower parts of your body. Your chest, belly, and knees may sink into a luxurious foam while your midriff and legs are supported correctly. Your spine is maintained in its natural S-curve position.

Is It Worth Buying A Cheap Memory

Very low prices generally come with a few trade-offs, including less transparency about materials, fewer layers, a cheaper cover, and not-so-great customer service. The biggest difference, however, is longevity. Cheaper mattresses are typically made with less-durable foams, which means they arent likely to last as long.

That said, a cheap mattress is worth considering if you dont expect to keep the same mattress for the next 10 years. A cheap mattress also makes sense if youre shopping for a bed for a seldom-used guest room, or if you simply dont want to spend a lot of money at a particular moment in time and dont mind the trade-offs.

Youll find several good options in our guide to cheap mattressesour favorite of which is the budget pick in this guide.

Memory foam is generally considered safe and non-toxic for people of all ages. However, kids may be more sensitive to the chemicals used to make and treat the mattress. They might experience allergies, asthma, headaches, breathing difficulty, coughing or nausea.

Because of the extra time that children spend sleeping and the fact that their biological systems are still in development, you may want to seek out a more natural alternative if youre concerned about an allergic reaction. There are organic mattress alternatives available that could be safer.

Also, be on the lookout for mattress certifications for assurances that the bed is free from harmful chemicals. Some to look for include Oeko-Tex and GreenGuard Gold. If the mattress youre evaluating has certifications like these, then theyre likely to be safe to use for anyone.

Does Your Mattress Have Sleep Trial

One important thing to consider is whether your mattress has a sleep trial. If the answer is yes, then you can contact the manufacturer and return the mattress as it is, saying that it didnt expand and that youre not satisfied with the service. The company will return your funds or offer to swap it with another mattress from the warehouse that will, hopefully, expand in its entirety.

Most professional mattress makers with good reputations offer sleep trials. These include Saatva, Nectar, and other reputable mattress makers. Cheaper mattresses usually dont have a sleep trial, but if you bought your memory foam mattress through Amazon, theres likely a 30-day return policy you could use.

Otherwise, see what you can do with your warranty if you have it. You can get your mattress replaced or fixed in a way that it can expand better.
