Faced with All kinds of information on the Internet, ranging from Single and Double mattress sizes to different sizes of mattresses from different places of production, no matter how clear your mind is, you will still have difficulty choosing. Let Sealy’s professional sleep consultants help you start a two-part journey to determine the size of your mattress!

There are many types of mattress sizes, and the most common ones can be roughly divided into 7 types, namely:
- Single

2. International unified mattress standards
At present, there is no uniform mattress size standard around the world. Even if the mattresses are the same Single size, the actual sizes of mattresses from different origins are different. Taking the width of a King size mattress as an example, there is a difference of more than 30cm between the European standard of 160cm and the American and Canadian standard of 193cm. Therefore, when purchasing a mattress size, do not just use names such as Single or Double , but express it in actual size.

| Single XL | 120x200 | 96.5 x 203.5 | 92 x 204 | |
| King Single | 107 x 203 | |||
| Double | 140 x 200 | 137 x 190 | 138 x 188 | 137 x 183 |
| Queen | 152 x 203.5 | 153 x 203 | 152 x 190 | |
| King | 160 x 200 | 193 x 203.5 | 183 x 203 | 183 x 198 |
| Super King | 180 x 200 | 183 x 213.5 | 204 x 204 | 183 x 203 |

Part 2: Tips for choosing mattress size
After understanding various mattress sizes, the next step is to choose a mattress size that suits you. You may wish to consider the following 5 points:
1. Mattress user
When choosing the size of a mattress, it is best for users to go to a Sealy store to conduct a comfort test in person, and try sleeping on the mattress for 10 to 15 minutes to see if the mattress will exceed the height by 20 to 30cm when lying down, so that the feet can have enough room to stretch. If you choose a Double bed, it is recommended to leave at least 40cm between the two people so that they will not feel crowded.
2. Bedroom space
Bedrooms in Hong Kong are generally small in size. It is not easy to strike a balance between the sleeping space on the bed and the activity space in the bedroom. Therefore, when purchasing a mattress size, do not just pursue a large mattress. You should also pay attention to the activity space in the bedroom. Otherwise, the sense of space in the entire room will be greatly reduced and the quality of sleep will be affected. Bedrooms in Hong Kong are generally thin. To make good use of space, the ideal bedroom design is to place the mattress Close to the wall so that any side of the mattress is about 75 to 90cm away from the wall of the room. From this, you can easily calculate the size of the mattress that suits your bedroom.
| Bedroom area | Ideal mattress size |
| Small (approximately 116 square feet) | Single , Single XL |
| Medium (approximately 176 square feet) | King Single , Double , Queen |
| Spacious (approximately 230 square feet) | King , Super King |
3. Pay attention to the impact measurement method of bed frame structure
If your bed frame is equipped with a bed frame and a headboard, you should pay attention to the fact that the bed frame has an outer frame and an inner frame. Also pay attention to the height of the headboard, otherwise the purchased mattress may not fit in the original bed frame. When measuring, please remember to measure the inner frame of the bed frame. Guests can also record their measurements and then inquire with our sleep consultant. If you are worried that the size of your newly purchased mattress and bed frame may not match, you may wish to go to the Sealy store to purchase mattresses and bed frames in one place.
4. Mattress Budget
Before deciding on the mattress size, you can set a budget first. Sealy offers different types of mattresses at affordable prices, and you can choose from different origins and specifications according to your needs. If you are looking for the sleeping feel of a 5-star hotel mattress or want to customize your mattress size, you can choose the Sealy hotel mattress series.
| budget plan | size | Sealy mattress recommendation | price |
| Economical choice (under HK,500) | 4 feet | Newton, the cost-effective choice for spine protection | HK,422 |
| Mid-range choice (between HK,500 and HK,500) | 4 feet | Best selling chiropractic model New Knightsbridge | HK,982 |
5. Potential future demand
It is best to take potential future needs into consideration when making your final purchase. For example, parents are buying a Single bed for their children who are studying in primary five and primary six. Since they are in the period of development, if they buy a 3-foot x 6-foot Single mattress, their children will grow taller in the future and may need to be replaced with a 3-foot
After considering the five aspects of mattress use, bedroom space, bed frame size, mattress budget, and potential future needs, you may not be able to find what you want out of the 7 common mattress sizes on the market.
