How to choose the needed size that will fit the room perfectly?

You can start with getting the dimensions of the room and consider the number of other furniture, and then block off the needed space in your room with the tape - if you need a Queen, block an area of 60” x 80” and see if it fits well. Then perform some actions in your room - anything you usually do, and see if you can do it freely without feeling cramped.

You should consider the furniture you want to purchase in future, too: it may influence your choice of the size as well. Also, think about the most important thing: do you need more space or a more luxurious bed?

Density, thickness, and firmness of mattresses – how to choose your perfect bedding

Another three essential criteria that should be discussed are density, thickness, and firmness of your mattress. These three factors will define the comfort level of your sleep.

Firmness: how to choose the proper one considering weight and sleeping position

Firmness is a universally subjective factor. One may prefer firm mattresses, while others may want to find the softest beddings available. How to choose a mattress based on firmness?

FirmnessFirmness scaleHeight of sinkageSuitable for (weight/sleeping position)
Super soft1-23-5 inchesPeople who weigh less than 100 pounds.
Soft3-42-3 inchesIndividuals who weigh 100-130 pounds and side sleepers.
Medium5-61-2 inchesSleepers who weigh between 130-230 pounds. Perfect for back and stomach sleepers.
Medium firm7-8Less than 1 inchHeavy individuals who weigh more than 230 pounds.
Super firm9-10No sinkageHeavy sleepers who weigh at least 100 pounds, hot sleepers, back sleepers, stomach sleepers.


Only foam-based mattresses can be organized based on this characteristic. A mattress with a higher density will feel more solid and much heavier than one with a lower density. Everything depends on your preferences and needs. The heavier the sleeper is, the denser mattress they should choose.

DensityWeight per cubic foot of foamSuitable for
Low3 poundsLight individuals who prefer to sleep on the back and side.
Medium4-5 poundsAverage individuals, who enjoy sleeping on the stomach, back, and side.
High5+ poundsHeavy people regardless of sleeping preferences.


Usually, the thickness of a mattress is defined by its owner’s weight. Most of the time, heavy users prefer thicker mattresses that can offer great comfort and support, while people who are light may enjoy less thick beddings.

Slim5-8 inchesGreat for people with limited mobility and kids and often used for twin beds.
Standard8-12 inchesGood for queen and king mattresses; suitable for most adults.

Thick20 inches and moreSuch mattresses are pretty difficult to move and quite rare; good for tall people

Where to buy a mattress: Online or offline?

If you have selected a type of mattress that you can afford, you should think about where to buy it. There are two ways: in-store and on websites.

Offline: pros & cons

  • Stores often offer great return policies, so you can either exchange your mattress if something is wrong with it or just return the mattress after paying a fee.


  • The range of available mattresses in one store is often limited, so you may have to visit several of them.
  • Salespersons can be quite “aggresive” trying to seel a particular mattress to you.
  • There are usually very high prices for mattresse, as the owners of stores have to pay rent and the salary to the consultants.
  • One can find it difficult to choose a mattress in a store, as some of them actively promote particular brands and it may influence the choice.

Lifespan of a mattress and how to take care of it?

One should choose a new mattress every 8-12 years. Have a look at the chart with the average lifespans of each mattress type - the lifespan is pretty different.

One of the simplest and most important tips regarding maintaining a mattress is you should rotate it regularly. Every 3-4 months rotate your mattress. It will allow both sides to recover from being used and offer you an even longer lifespan. Avoid putting more weight on your mattress as it can ruin its structure.

Please, note: warranty does not show the real lifespan of a mattress! Some companies offer a lifetime warranty, and it does not mean that your new mattress will last for several decades and provide you with proper spinal support. You can check the actual lifespan of a mattress on the website of a mattress brand you choose.

How to choose a suitable mattress - conclusion

Let’s sum up what you need to know to choose the right mattress!

  1. What kind of sleeper are you? If you are a hot sleeper, then choosing a foam-based mattress is not a great option for you! Innerspring, hybrid, or latex are a more suitable choice.
  2. What is your weight, height, and body type? Heavy individuals would feel more comfortable while sleeping on thick and firm mattresses, while lighter people would prefer soft and beddings.
  3. How much do you wish to spend? Your budget defines the options that you have. If you can spend less than $700, then an innerspring or an affordable memory foam mattress is your choice. If you have a budget of $1,500, you can look for a luxurious innerspring bedding, a great latex or hybrid mattress, or expensive memory foam one.
  4. What is your preferred sleeping position? Whether you are a back, side, or stomach sleeper, you need to consider the firmness, thickness, and type of a mattress. Back and side sleepers usually prefer medium firmness while stomach sleepers like to sleep on firm mattresses.
