What to consider when choosing the mattress size
Choosing the right mattress size for your bedroom can sometimes be a daunting task. From a double bed to a queen, a king, or an economical single, there are a variety of mattress sizes to choose from. In order to make sure you pick the perfect size for your needs, there are a few factors to consider.
1. Choosing the right mattress for your room size
First, the size of your bedroom will play a role in the size of mattress you choose. If the room is too small, a larger mattress may not fit, or the room may feel cramped. On the other hand, if the room is too large, a smaller mattress may look out of place. Make sure to measure the dimensions of the room, and consider any furniture that may already be in the room, to ensure that the mattress will fit and still allow you to move around your room without problem. We suggest ensuring at least 60cm of free space at all sides of your bed to ensure comfortable moving around, more if you use mobility aids or struggle walking or getting in and out of bed.
If you’re limited on space and sleep alone, a single, long single, or double sized mattress might be the best option for you. On the other hand, if your bedroom is large, you’ll have more options, like a queen, king size, or split king mattress.
2. Choosing a bed based on your height
Second, your height may also play a factor in what mattress you should choose, as we recommend choosing a mattress that is at least 15cm longer than the tallest person sleeping on it. So that means if you’re taller than 173cm, you should avoid a single mattress and double mattress, and instead opt for a long single, queen, or king sized mattress. If you are shorter than 173cm, you don’t need to worry much about the length of your mattress when making your choice.
3. Choosing the right mattress for couples and co-sleepers
Next to consider is the number of people who will be sleeping on the mattress. Different mattress sizes can accommodate different numbers of people, so it is important to consider the needs of everyone who will be sharing the bed. If two people will be sharing the bed, a queen or king-sized mattress may be the best option for providing enough space for both. If there will only be one person sleeping on the mattress, a single, double, or queen sized mattress should suffice.
4. Consider your budget while shopping for a mattress
Your budget is also an important factor while choosing a mattress size. Higher quality mattresses often cost more, and larger sizes will also be more expensive. Before you make your purchase, make sure you settle on a budget that you can afford.
5. Consider how you sleep
Finally, your sleeping style should be taken into account when selecting a mattress size. If you move around a lot while you sleep, a larger size mattress can provide more space for you to move. If you prefer a firmer mattress, a smaller size might be best.
6. Consider your existing bed base
Buying a mattress and a bed base at the same time is a wonderful way to improve your sleep at once, but it can be costly. That’s why many choose to upgrade one or the other, and this can impact what mattress you can opt for. If you have an adjustable bed base, you need a malleable mattress such as a latex mattress. However, if you’re looking to invest in a natural latex mattress, you need to be sure that your current bed base can support it.
When you’re shopping for a new mattress, it’s important to consider these factors to ensure you get the right mattress for your needs and comfort.

Single size mattress
- Dimensions : 188cm (L) x 92cm (W) x 21cm (H)
 
Single size mattresses are the smallest out of all the sizes available in the Peace Lily mattress range and it is best suited for smaller individuals or those with minimal space available for a mattress. Single mattresses are also commonly used for kid's beds or bunk beds, making them the perfect option when the time comes to upgrade to a big kid bed. If money is a concern, single mattresses are more affordable over other sizes and fit perfectly for a smaller bedroom.
A single mattress may not be suitable for your needs if more than one person will sleep on the mattress. For a co sleeping mattress, or a mattress intended for someone taller than 173, we recommend opting for a larger size. Not only will it be more comfortable, but it will also ensure that your mattress does not prematurely sag from excess weight.
Long Single size mattress
- Dimensions : 203cm (L) x 92cm (W) x 21cm (H)
 
The Long Single Mattress is 15cm longer than a standard Single size mattress which allows you to stretch out more freely and accommodates taller individuals. On its own, this size is great for growing children and taller adults who need a bit more space to sleep. If you’ve got a small bedroom on your hands and are a single sleeper, a Long Single mattress is an ideal mattress choice as it provides more room lengthwise without taking up too much space overall.
The long king single mattress is not suitable for regular use for more than one person, so if you are shopping for a co sleeping mattress, we recommend opting for a larger sized mattress. We also recommend choosing a larger mattress if you think you may be sharing your mattress with someone else in the future. A latex mattress is a quality investment backed by a 25 year warranty (that means it’s under warranty almost until 2050) - we’d hate to see you having to buy a second mattress in a few years time to accommodate another person.
King Single size mattress
- Dimensions : 203cm (L) x 107cm (W) x 21cm (H)
 
King Single Mattress is the more spacious edition of Single Size mattress. It’s the perfect choice for taller people who have limited space available for a mattress but would like a bit more space to sprawl. The King Single Mattress is space efficient yet allows you to sprawl and stretch out comfortably.
The King Single Mattress on its own is not suitable for cosleepers. If you cosleep with pets, children, or another person, consider a larger mattress.
However, if you’re a couple looking for an adjustable bed with ample space, individual comfort possibilities, and less partner disturbance, this is the perfect mattress size for you. That’s because you can combine two King Single mattresses into a sophisticated split king bed system. This means one person can enjoy the massage settings in zero-gravity mode on their side of the bed while the other sleeps in a flat position on their side.
Double size mattress
- Dimensions : 188cm (L) x 138cm (W) x 21cm (H)
Double mattresses are popular with parents buying a slightly bigger bed for their preteen or teenaged kids, or for single adults. It also makes an ideal option for a guest room too, as it comfortably sleeps one guest and can generally sleep two guests for a few nights.
Don’t let the name ‘double’ fool you - a double mattress is indeed not the ideal choice for a couple to sleep on. While it’s fine to sleep on for a couple of days, you’ll feel cramped and your sleep may be impacted over time. If you’re a couple looking for a new mattress, we recommend opting for a queen size or a king size mattress to ensure the both of you have enough space to stretch out and sleep comfortably.
Queen size mattress
- Dimensions : 203cm (L) x 153cm (W) x 21cm (H)
A Queen Size Mattress is a great choice for couples who don’t feel they need the sprawl of a king size mattress, or may not have the space to accommodate one. It is also a good choice for individuals who sometimes share their beds with others or who prefer more space to sleep and move around in. Queen-sized mattresses provide plenty of space for two people to sleep comfortably. They are also a popular choice for guest rooms, as they can accommodate a single person or a couple.
We don’t recommend a queen sized mattress if you cosleep with young children or several pets because your sleep may be disturbed by heat, movement, and lack of space. If you plan to cosleep on your mattress and you have the space and budget, we suggest opting for a King sized mattress.
King size mattress
- Dimensions : 203cm (L) x 183cm (W) x 21cm (H)
King Size Mattress is the biggest out of Peace Lily Mattress range. A king-sized mattress is a type of mattress that is typically recommended for couples who want more sleeping space than what a queen-sized mattress offers. It is also a good choice for individuals who prefer more space to sleep and move around or parents (of children or fur babies) who co-sleep. The Peace Lily king-sized mattresses are 183cm wide and 203cm long, providing plenty of space for two people to sleep comfortably. They are also a popular choice for master bedrooms, as they provide premium comfort and can accommodate a single person or a couple.
Split King (Two Long Single Mattresses)
- Dimensions : 203cm (L) x 184cm (2x92cm) (W) x 21cm (H)
The Peace Lily split king system is perfect for couples who enjoy sleeping next to each other but also enjoy minimal partner disturbance and individual adjustability. One partner may enjoy relaxing with a book and the built-in massage setting digging into their sore muscles, while the other wants to catch some z’s in the zero-gravity position.
Well, with a split king system, this is possible. This system is recommended for couples with the budget and space to accommodate it, and is a luxurious investment for the future.
This bed is not recommended for solo sleepers, as the standard king sized adjustable bed and mattress will be a better fit.
