Factors To Keep in Mind Before Buying 12 Inch Memory Foam Mattress

The first time, you may find it quite challenging to find the right type of king-size mattress. Of course, for better sleep, you cannot compromise with certain factors. And for this, there are certain buying guides that can be of great help to you. Whether it is about the foam, size, or price, all things need to be carefully understood. The best part is the more you research, the better are chances for you to jump to a conclusion. Follow the given below tips that may help.

  • Understanding the sleep system first: It is important to know what way you basically sleep. Some tend to spread their legs and sleep while for some to sleep on the stomach side is comfortable. Some sleep taking only one tiny corner while for some even the entire bed will be less. If you are one of those who tend to occupy much space,, of course, you need to choose the size which is quite big amongst the entire king-size beds.
  • Cheap is not the answer: Of course, if you want to save money, there are cheap mattresses that are available. But again, you will be compromising on the quality. Such mattress will last not more than 2 years and then again you will have to buy another one. That is why it is always better to choose the one that can last for at least 5 years or more without any reason for you to even complain.
  • Weight and size matter: If you have tall people in the house, then it is important to choose a mattress with good width and height. You need to, however, also don’t just get tempted with those hotel pattern mattresses. They are only meant to give you comfort for a day or not. The mattress for routine sleep needs to be firm and a little sturdy too and that is why choose the one which is light and can give you a sound sleep too.

Look for the quality of the foam used in the mattress. Generally, visco-elastic foam is designed to reduce the pressure points and thus ensure the weight of the body is evenly spread. These can be easily recognized in the market. Besides, the problem of dust mite will not persist and is best designed for people having asthma or joint issues.

How To Clean the Memory Foam Mattress Stains

Often times there are stains that get attached to the mattress and cleaning them off is a hard task. But if you take a bit of closer effort to the type of the stain, then you can easily clean it off. Here’s how you can do it. 

  • Find the Type of Stain

Stains can be of different types ranging from sweat, blood, oil, urine, and other body fluids. These tend to create a stain on the mattress. So look for the type of stain and then you can treat it accordingly. Remember each strain is different from the other one so treat them differently. 

  • Cleaning the Bloodstains

It’s not unusual to get the bloodstain on the mattress. It may be because of the wound or the periodic blood or other reasons. You can clean them off easily with the combination of hydrogen peroxide and liquid soap mixed with the table salt. Mix the mixture well and apply it to the fabric. Let it rest for a while and use a rag to remove the stain by gently applying circular motion to it. Use a white rag as that will stop the transfer of color of the dye to the mattress. 

  • Cleaning the Urine Stains

If you have children back at home, then it’s not unusual that you have the urine on the mattress time and again. You often dry them out in the open and let them seat out. It does clean off the odor but the stain may remain yet. So here’s how you can clean it off. Go for the combination of 3 tbsp of baking soda mixed with the hydrogen peroxide as that will help clean the stain. Also, mix in some liquid soap and apply the mixture to the stain with the use of the white rag. The stain should be removed in no time. You can also use the detergent for cases when the stain persists. Apply the paste of detergent and water to the stain and let it be there for half an hour. You can then clean off the stain with the use of a white rag and later vacuum it for sucking in the dirt. 

  • Cleaning the Vomits

There’s nothing to be ashamed of this one. It does happen, there are times when vomit tends to end up on the mattress and creates a stain on the mattress. These require a bit different treatment than the normal stains so as to clean it up. We advise you to open the window and let the air breathe in. Use undiluted ammonia and take a white rag along with you. Dip the area with the ammonia and clean the surface of the stain with it. After cleaning off the surface with ammonia you can use the baking soda to help remove the odor and moisture from it. Apply the baking soda mixture and let it dry. You can then vacuum it and it would be cleaned off.  Having a sound sleep is a must if you want to have better health and lifestyle. Sleep is often the precursor for greater health benefits and it’s always advised to rank in as much proper sleep as you can. Here’s where the mattress comes into play. They tend to facilitate proper sleep and help you achieve better goals and feel more refreshed after a long night haul. 

Don’t ever compromise on your mattress as that is where you tend to let go of the major health benefit. Look for the best one as per your suitability and need and you can then enjoy a relief sleep over the night. No more tossing around due to lack of sleep thereafter for you.
