Mattress and bed size guide: Do you need single, double, queen or king?

Choosing your mattress is a critical decision any homeowners should make. If you are moving in to a new home or trying to replace your old mattress, it is crucial that you know what exactly you should look for in identifying the best mattress to suit your need.

While there are a variety of mattresses being offered in the market ranging from variations in size and materials, the most critical aspect of it is choosing the right mattress for your bed size. The mattress size allows you to identify some of your sleeping requirements, which are discussed below to help you identify the perfect mattress size to fit your need.

Mattress Comparison Guide

1.      Single Size Mattress:

Single Size Mattress

The single mattress is sized 92 cm x 188 cm. The single size mattress is popular among people who sleep alone or who resides alone in their apartment, boarding house or home. This is the most common bed size for children, kids’ bed and bunk beds. Consider opting for a single bed and a single mattress if you are living alone. This is the most common bed size for children, kids’ bed and bunk beds.

Additionally, single beds also appear in small apartments where individuals live alone like boarding houses, studio rooms, bunk beds, and anything of the sorts. While you can find other ways to use a single size mattress, it's ideal for people living alone or for children transitioning to a more roomy bed.

Here are some benefits of choosing a single bed:

  • They're more affordable than other bed sizes.
  • Compact and ideal for smaller rooms.
  • They take up less space, making them ideal for small bedrooms.
  • They're easy to move, so you can rearrange your furniture with ease.
  • You don't have to worry about your partner stealing the covers!

If you're looking for a bed on a budget, or you don't have a lot of space to work with, a single bed is a great option. Just because it's the smallest size doesn't mean it can't be comfortable and stylish.

Single beds vs. Twin beds

While single beds and twin beds may look similar, there are a few key differences between the two. The biggest difference is size, as twin beds are slightly wider and longer than single beds.

Another difference between single beds and twin beds is that twin beds are designed for two people to sleep in, while single beds are meant for one person. This means that twin beds will have a bit more space to move around and be comfortable.

Ultimately, a single bed is ideal when your budget can't accommodate other mattress sizes or when you have a resting area for your small room. However, note that despite its small size, it's still comfortable and can fit in a stylish bed frame.

2.      King Single Size Mattress:

The king single mattress is a variation of the single size mattress. It is sized at 107 cm x 203 cm. It is perfect for those who are above average in height who are living alone. Purchasing a king single bed give you the advantage of not needing to buy another bed for your growing kid.

It's also a common option for adult students in apartments, hustles, and shared houses. If you don't own a hostel or aren't purchasing for your children, note that the bed size is also compatible with guest rooms because using a double size bed, or anything larger, may cramp up the room.

Benefits of a king single bed:

Factors to Consider When Buying A Mattress

Before acquiring your new mattress for your home, children, hostel, or single room, there are some important factors to consider. These elements will help pick the best option and enjoy your purchase months or years later.

Here what you need to consider:

1. Budget

First understand how much you're willing to spend on a new mattress as this action will help to keep your bank balance in check and prevent you from getting ripped off. Essentially, take your time to research the price range for your desired mattress before going shopping.

2. Mattress Size

The mattress size is often determined by your lifestyle such as whether you live alone, have a partner, have kids, use the bed often, etc. Also, your bedroom size dictates your bed's dimensions as a larger room can accommodate a queen or king size bed, while a smaller one is ideal for a single, king single, or double size mattress.

Your mattress firmness comes down to your preference as there is no wrong or right answer. Simply choose the one you enjoy the most as the options include:

  • Plush beds – adjusts to your body’s curves
