 Twin size mattress is the smallest mattress that the mattress companies manufacture and sometimes referred to as single bed mattress. Its small size makes it ideal for kids, single sleepers and to be used with bunk beds.

However, if you are a tall and bulky guy, we will not recommend you buy twin size bed. We will also not recommend twin size mattress for active sleepers who tend to move a lot while sleeping.

The twin XL mattress can be considered as the ultimate single sleeper mattress that can accommodate tall, short and medium height individuals. These beds are ideal for college dorms as they can give young inspiring students extra space to feel comfortable while sleeping.

But we don’t recommend twin size beds for active sleepers and the sleepers who have pets.

Most of the time people get confused while buying bed sheets or comforters for their twin or twin XL mattress. We highly recommend telling sales representatives that you need twin or twin XL bed sheets or comforters as most of the bed sheets or comforters’ manufacturers don’t produce sheets or comforters for twin XL mattresses.

 The full-size mattress is the standard double bed mattress and is sometimes referred to as the standard couple’s mattress.

The full-size mattress is about the same length as a twin-size mattress, but it is 16 inches wider than a twin size mattress. This extra size 16 inches transform a twin mattress bed into a full mattress bed.

 

The wider design makes it ideal for couples and for the sleepers who love to move all over the bed while sleeping. Likewise, its small length makes it suitable for rooms that are small, and they are ideal pick for guest rooms, hotels and Airbnb rooms.

The additional size makes it a good fit for most of the buyer.

Queen size mattresses are ideal for tall active sleepers. The mattress can easily accommodate couples that are tall and have a baby or pet that sleep with them. However, if you are a couple and have a baby or pet, we highly recommend you king size bed over queen size bed just for the sake of extra space and comfort.

The king size mattress has a majestic feel to it that comes from its massive size and its premium stature. In modern term we can also say that king size mattresses are the flag ship mattresses that the mattress manufacturers produce.

They usually have massive price tags attached to them thus, most of the people will not consider them while buying a mattress for their guest room and Airbnb room. Size of a king size mattress is extreme big which makes it not suitable to be placed in a small room.

King size mattresses are best for active sleepers as they have a huge space to toss and turn while they sleep. Believe me on this it feels like you are the king, if you are a single sleeper that sleeps on a king size bed.

Moreover, the king size mattresses are ideal for couples. We highly recommend going for a king size mattress if you are a couple with kids, baby or loves to sleep with pets.

For the sake of information, let me tell you that. You can also use two twin XL mattresses on the frame of a king size bed. Yes! This quality of the king size mattress makes it perfect for the couple who like to achieve different feel from their mattress.

The Cal king beds were specially designed by David Bergeson from Concord, CA. He invented the Cal king bed in 1982 to accommodate his very long legs. So, the prime motive of a Cal bed is to fulfill the needs of sleepers who are over 6.5 feet tall(1).

Since then Cal King beds have been one of the major bed sizes that the mattress manufacturers produce. Cal King beds are ideal for tall couples and bulky couples or for couples who just want extra length to their bed.

We highly recommend going for a king size mattress if you are a couple with kids, baby or loves to sleep with pets because king size mattress gives you extra 4 inch width.

The Cal King bed has a premium luxury feel to it and it can be considered as the most preferred mattress by active sleepers due to the extra leg space that they get in Cal king beds in comparison to standard king size beds.

  • Ideal for sleepers who are looking for a premium level mattress but slightly longer.

Before Choosing a mattress/bed size.

The answer to this question, “which bed size is best for me?” greatly depends on your preferences and needs. There are number of things that you should ponder upon before choosing the bed size you should buy.

Let me help you by narrowing down the needs and preferences so that you can get to the bed that truly serves your desires.

Firstly, you should think about whether you are an active sleeper or not? Are you the person who usually love to move all over the bed while sleeping or fell out of the bed when sleeping on a small bed?

You should also keep in mind that how many people will be sleeping on the bed? Do you have a pet cat or dog that sleeps with you? Or do you have a baby that will be sleeping alongside mum and dad? Or do you like to keep your laptop and other things laying on the bed while sleeping? Well don’t tell anyone but I am the kind of person who like his laptop, smart phone, and silky aka my pet cat laying on my bed while my mum gets angry.

Another thing that should be noticed in this process is whether you are a tall or short person? And is your room big enough for the bed that you are about to buy?

We highly recommend measuring your room before choosing which mattress to buy as it will give you an idea on how much space you have for the new bed.

Another thing that I just remember, if you don’t know the measurement of your bed frame. You should also measure the frame and see which mattress will fit on it by comparing the stats of the frame and the available mattresses.

Another key thing that everybody should do before buying a mattress is thorough research. We have an article about best mattresses/beds that will give you a detailed overview of 10 mattresses, their key features and editor’s recommendations. Check it out.

Why Do you need to do Research before buying a new bed/mattress?

Now you will surely, say buying bed/mattress is a hectic process? Why I should do all these things I can just go to the market and can pick up some bed that will look most suitable.

The thing is that buying a new mattress/bed is a significant investment. The mattresses in the market varies from $500 to $1500 and if you got a wrong mattress then you have to go through the return policy process which is time consuming, then you had to start all over again as you need a new mattress after all. Then it is best to do some homework and research before buying a new bed/mattress.

Mattress/ Bed Sizes and Dimensions Summary

There are many standard bed sizes available in the market that makes it quite difficult for a buyer to make up his/her mind about which mattress/bed size is best for his/her needs.

As most people don’t likely to do research before buying a bed, most of the time they end up buying a bed that is not suitable for them. Thus, they end up requesting a refund or return from the manufacturers. The mattress companies have a very effective return policy. It usually takes a week or two to get your money back.

Nevertheless, it does not resolve the issue as you still need a new mattress. Again, you have to go through the entire process of buying and still there is a probability that you will get the wrong bed.

So, in order to get to the safe side. We highly recommend doing research before buying a bed or mattress. You can check out our blog on best mattresses/beds.
