What Is a Full Mattress?

A full mattress, also called a double bed, measures 54 inches wide and 75 inches long. It’s larger than a twin (38 inches by 75 inches) but smaller than a queen mattress (60 inches by 80 inches) or a king (76 inches by 80 inches). While it’s a popular choice for single sleepers, the situation becomes more complex when two adults are sharing it.

To put the space into perspective, a full mattress provides each person with only 27 inches of sleeping width. When compared to queen mattresses, each adult sharing a full bed has 6 inches less width to work with, and the bed is also 5 inches shorter in length.

Full Mattress Dimensions

Given these dimensions, a full bed is often seen as a great fit for:

  • Single adults who want more space than a twin bed.
  • Children or teens who might outgrow a twin bed but don’t need a queen or king.
  • Guest rooms where space is limited, but a twin bed feels too small.

Is a Full Mattress Comfortable for Two Adults?

When considering if two adults can sleep comfortably on a full mattress, it’s essential to evaluate a few key aspects. These include sleeping positions, body size, sleeping habits, and preferences for personal space. Let’s break them down.

1. Sleeping Positions

The sleeping positions of both individuals greatly influence how comfortable a full mattress will feel. With limited space, certain positions work better than others:

Back Sleepers: If both individuals sleep on their backs, a full mattress might be manageable. Since this position takes up less horizontal space, couples can often share the bed without feeling too cramped.

Side Sleepers: Couples who sleep on their sides may find a full bed more challenging. Side sleepers  require more room to spread out their arms and legs, making it difficult to get comfortable on a narrow mattress.

Stomach Sleepers: This position tends to take up more room because it requires space for arm placement. Two stomach sleepers will likely feel restricted on a full mattress, especially if they move around during the night.

Combination Sleepers: If one or both individuals change positions frequently throughout the night, it’s easy to bump into each other or invade each other’s space. For combination sleepers, the limited width of a full mattress can be frustrating.

2. Body Size and Height

The body size and height of both sleepers also play a significant role in determining whether a full mattress can accommodate two adults comfortably.

Smaller or Petite Individuals: If both people are smaller in stature, the full bed may feel more spacious, especially if they are used to sleeping in close quarters.

Average-Sized Adults: For people of average build, a full mattress can start to feel tight. With only 27 inches per person, there’s little room to stretch out, which can result in discomfort during the night.

Taller Adults: Anyone over 6 feet tall may have trouble sleeping on a full mattress. The 75-inch length of the mattress is equivalent to 6 feet, 3 inches, which leaves little room for taller individuals to fully stretch out. Many taller sleepers may find that their feet hang off the end of the bed, which can make it difficult to get a restful night’s sleep.

3. Movement During Sleep

Movement is another factor that can make or break the experience of sharing a full mattress. If one or both individuals tend to move frequently during the night—whether it’s tossing and turning, shifting positions, or getting up for a drink of water—this can disrupt the other person’s sleep.

4. Closeness Preferences

The level of closeness each person prefers is also critical to consider. Some couples love to be physically close while sleeping and enjoy the intimacy that a smaller bed can provide. For these couples, a full mattress could work perfectly.

On the other hand, some people need a bit more personal space while they sleep. If you or your partner are the type who likes to have room to stretch out without touching the other person, a full mattress might feel too cramped.

Benefits of Sharing a Full Mattress

Despite the challenges, there are some advantages to sharing a full mattress. These benefits may appeal to couples or roommates who are prioritizing budget, space, or closeness in their sleeping arrangements.

1. Cost-Effective

One of the most appealing aspects of a full mattress is its affordability. Full mattresses are generally much less expensive than queen or king mattresses, making them a budget-friendly option for couples looking to save money. Whether you’re furnishing a new apartment or simply looking for a cost-effective solution, a full mattress can offer great value for money.

2. Space-Saving

If you’re living in a small apartment or have a compact bedroom, a full mattress takes up much less floor space than a queen-size bed or king-size bed. This can be important if you’re trying to maximize space in a studio apartment or a shared bedroom. The smaller footprint of a full mattress can help free up space for other furniture, like a dresser or desk.

3. Encourages Closeness

For couples who enjoy cuddling or being physically close while sleeping, a full mattress can help foster intimacy. The smaller space naturally encourages more contact throughout the night, which can strengthen your bond as a couple. If you and your partner enjoy snuggling, the reduced space on a full mattress can actually be an advantage.

Tips for Making a Full Mattress Work for Two Adults 

If a full mattress is your only option or you’re committed to making it work, there are several strategies you can use to improve comfort and sleep quality.

Invest in a High-Quality Mattress

A high-quality mattress is essential if you’re sharing a full bed. Look for a mattress that offers good support and motion isolation. Latex mattresses, in particular, can help absorb movement, so if one partner tosses and turns, the other person is less likely to be disturbed. A mattress that provides proper back support is also crucial, especially when space is limited, as it ensures both partners get a good night’s sleep without discomfort.

Use Separate Blankets

One simple solution to avoid disturbances during sleep is to use separate blankets. With each person having their own blanket, there’s less chance of blanket-hogging or waking the other person when adjusting the covers. Separate blankets also reduce the likelihood of accidental pulling or yanking of the blanket, allowing both individuals to sleep more soundly.

Try Different Sleeping Positions

Experimenting with different sleeping positions can help maximize comfort on a full mattress. Spooning or lying back-to-back can help conserve space while still providing enough room for both individuals to feel comfortable. If you’re both back sleepers, try lying side by side with your arms down by your sides to avoid encroaching on each other’s space.

Keep the Bed Clutter-Free

A cluttered bed can make a full mattress feel even smaller than it already is. Try to minimize the number of pillows, decorative cushions, or stuffed animals on the bed to maximize sleeping space. Keeping the bed as minimalist as possible will give you both more room to spread out, making the small mattress feel less restrictive.

The Bottom Line

While it’s possible for two adults to share a full bed, comfort levels will vary based on sleeping positions, body size, and movement habits. If you and your partner enjoy sleeping close together and don’t mind a bit of snugness, a full mattress can work, especially in situations where space or budget is limited.

However, if either person values personal space during sleep or if either partner is taller or prone to tossing and turning, the restricted space of a full mattress might lead to discomfort or sleep  disturbances. In these cases, upgrading to a queen- or king-size mattress could be a better long-term solution for achieving a restful night’s sleep.

If a full mattress is the right choice for your situation, applying some of the tips mentioned above can help improve your sleep quality and comfort, allowing both you and your partner to get a better night’s rest.
