How to Choose a Mattress with the Best Thickness

  1. Body weight – When determining how thick your mattress should be, the first thing you should think of is your body weight. If you are heavyweight, you will definitely need a thick mattress that can support your body weight. The best mattress for heavy people should be at least 12 inches thick. It should also be firm enough to support your weight. If you are not sure which mattress suits your body weight, you should consider the following;
  • 150 Kg and above – 12 inches or more
  • 150 Kg and below –  10 to 12 inches
  • 120 Kg and below –  8 to 10 inches
  • 100 Kg and below – 6 to 8 inches
  •  80 Kg and below –  4 to 6 inches

Most of the Indians weight less than 100 Kg and therefore we have 6 inch mattresses very popular here. If you are looking for more bounce and comfort, then go for an 8 inch mattress. Otherwise, a 6 inch mattress does its job pretty well.

  1. Couples – In case you share the bed with your partner, you need to ensure that the mattress can support your weight. If the mattress is very thin, a crater may form at the centre after using it for a short time. The best mattress for young couples should have a thickness of between 6 to 8 inches. These mattresses might be a bit expensive but they are worth the price because they are very comfortable.
  2. Mobility – People with limited mobility should consider a thin, 4 inch mattress. Since these mattresses have a low profile, they allow people with limited mobility especially those with injuries to get in and out of the bed easily. They are also the best for petite people and kids.
  3. Medical Conditions – Your health condition will also determine the best thickness you should consider when buying a mattress. For example, if you suffer from back pain problems, you will need a firm mattress. In case you suffer from arthritis, hip or shoulder pain, you need a mattress with several comfort layers that can relive pressure from different parts of your body.
  4. Temperature Control – Thick mattresses are the best in terms of comfort. However, they are likely to trap more heat which may cause discomfort at night in summers. When buying, ensure that it is made of breathable materials like natural latex foam.
  5. Placing the mattress on your floor – Some people may prefer to place the mattress on the floor instead of placing it on the bed. If this is what you prefer, you should look for a thick mattress. The floor is full of harmful impurities and using a thin mattress will be very dangerous for your health. Again, a thin mattress will cause a lot of discomfort and may also lead to back pains. Placing the mattress on the floor may also affect the durability which means that you need to ensure that the base is clean, sturdy enough, and durable. The best mattress should have at least 12 inches if you are planning to use it on the floor.
  6. Sleeping style – This is another important feature you should not ignore. If you are not sure about the best thickness that suits your sleeping style, you should consider the following.
    • Back sleepers – If you are a back sleeper, you should consider a mattress with a medium level firmness. This means that you should consider a mattress made of latex foam or memory foam with about 6 inch thickness and firmness of 4 to 6 scale (out of 10 which is the hardest). Such a mattress will give you the best support.
    • Stomach sleepers– Sleeping on your stomach may put extra pressure on your lower back. In order to prevent discomforts, you should consider a mattress with about 6 inch thickness and firmness of 5 to 7 scale (out of 10 which is the hardest).
    • Side sleepers – This position may put pressure on your hips and shoulders. The best mattress for side sleepers should be soft with medium firmness and should relive pressure on key parts of your body. It should have a thickness of 6 to 8 inches and and firmness of 3 to 6 scale (out of 10 which is the hardest).
    • Combination sleepers– People who can sleep on any side are known as combination sleepers. In case you are one of them, you should look for a mattress which is at least 8 inches thick with firmness of 5 to 6 scale. This will be very comfortable when you are sleeping either on your back, stomach or side. The mattress should also provide a great balance of softness and firmness. Avoid mattresses that are too soft and bouncy.

      A 4 to 5 inch mattress is sufficient. But go for a 6 inch thick mattress if you can afford. Also check if it will fit the bed.
