If you are setting up a shared bedroom for one adult and one child, the choice between a full and queen mattress comes down to space, sleep style, and how long you plan to use the bed. Our editorial team compared specifications, buyer feedback and key decision factors to help you make an informed choice.
Direct Answer: Which One to Choose
For one adult and one child, a queen mattress is usually the better choice if the room can accommodate it. The extra 6 inches of width (60 inches total vs 54 inches) provide more personal space for both sleepers, reducing the chance of elbows and knees colliding during the night. A queen also offers more room for a child to grow into, so you won't need to replace the bed in a few years.
However, if the bedroom is small, a full mattress can work well, especially if the child is young and small. A full is 54 inches wide and 75 inches long, which gives each sleeper about 27 inches of width. That is similar to a crib mattress width, so a toddler or young child will be comfortable. The shorter length (75 inches) is fine for most adults under 6 feet tall, but taller adults may find a queen's 80-inch length more comfortable.
Consider your child's age and sleep habits. If your child tends to sprawl or move a lot, the extra width of a queen is worth it. If the child sleeps still and is under 10, a full can be a space-saving solution.
Dimensions and Space Requirements
Understanding the exact dimensions is key to making the right choice. Here is a quick comparison:
- Full mattress: 54 inches wide by 75 inches long. Also known as a double bed, it is the smallest size that can reasonably fit two people, but it is tight.
- Queen mattress: 60 inches wide by 80 inches long. It is the most popular size for couples and offers a good balance of space and room footprint.
When measuring your room, remember to account for the bed frame, which adds a few inches to each side. You also need space for walking around the bed and for other furniture like a dresser or nightstand. A general rule is that a queen bed needs a room of at least 10 feet by 10 feet to feel comfortable. A full bed can work in a room as small as 8 feet by 10 feet.
If you are working with a tight space, consider a full mattress with a minimalist frame. If you have the room, a queen offers more flexibility for future needs, such as a growing child or occasional guests.
Comfort and Sleep Habits
Comfort is subjective, but there are practical factors to weigh. For one adult and one child, the main comfort issue is space. A full mattress gives each person 27 inches of width, which is about the width of a crib mattress. That might be fine for a small child, but if your child is a restless sleeper, they might wake you up. A queen gives each person 30 inches, which is closer to the width of a twin XL mattress, offering more freedom to move.
Another factor is the type of mattress. Both sizes come in all firmness levels, from soft to firm. If you share the bed with a child, you might prefer a medium-firm mattress that provides support for both of you. Memory foam and hybrid mattresses are popular for motion isolation, which can help if your child tosses and turns.
Think about the long term. A queen mattress is a standard size that fits most bed frames and bedding. Full-size bedding is also easy to find, but queen is more common for shared sleeping. If you plan to use the bed for many years, a queen is a safer investment.
Here is a step-by-step approach to help you decide:
- Measure your bedroom and note the dimensions, including doorways and closet space.
- Consider the age and size of your child. If they are under 10 and sleep still, a full may suffice.
- Think about your own height. If you are over 6 feet tall, a queen's extra length is beneficial.
- Evaluate your budget. Queen mattresses generally cost more, but the price difference is not huge for budget models.
- Check the current price on Amazon for both sizes in the brand you like.
Frequently Asked Questions
Can a full mattress comfortably fit one adult and one child?
Yes, a full mattress can work for one adult and a small child, especially if the child is under 10 years old. The 54-inch width gives each sleeper about 27 inches, which is similar to a crib mattress width. However, if the child is a restless sleeper or older, a queen's extra 6 inches of width can make a noticeable difference in comfort.
Is a queen mattress too big for a child's room?
It depends on the room size. A queen mattress requires a room of at least 10 by 10 feet to allow for walking space and furniture. If the room is smaller, a full might be more practical. Measure your room and consider that a queen bed frame adds about 5 inches to each side compared to the mattress dimensions.
What is the price difference between full and queen mattresses?
Generally, queen mattresses cost more than full mattresses because they use more materials. However, the price gap varies by brand and type. You can find budget-friendly options in both sizes. Check the current price on Amazon for specific models to compare.
