The Best Mattress Sizes for Singles

Single people need quality sleep as much as anyone else. However, how do you know which size mattress is best for you? The best mattress sizes for singles often depend on a mix of personal preferences and body type. In this article we’ll explore a variety of mattress sizes and how they can benefit the single sleeper.

Think About Your Needs

When it comes to mattress size, the main problem to avoid is having too little space. After all, you need to be able to stretch and roll over with room to spare. For this reason, you should always first consider your body size. Secondly, determine whether you plan to be single for a long time. If so, a mattress exactly right for you is fine. If not, you’ll want to plan for the future and allow more sleeping surface.

The Best Mattress Sizes for Singles with Limited Space

If you live in a tiny flat, you might not have space for a bigger bed. A twin size mattress is only 38”W x 75”L. As a rule, we don’t recommend a twin size mattress for a single adult. Not only is the length not ideal, but the width can be tight as well. However, if space is limited and your body size allows for it, a twin size mattress can be a perfect fit. For a bit more length, a twin XL size mattress can offer more head and leg room.

If your bedroom space allows, a full size mattress is more adult friendly. At 53”W x 75”L, there’s a bit more room to stretch out than a twin will provide. A full XL size mattress extends the length by five inches, which will allow more head and leg room. With the width of a full size bed and the length of a queen, a full XL is the smallest recommended size mattress for a single adult. While it won’t provide optimal space to stretch out, it will make a comfortable compromise.

Though a full XL mattress can comfortably sleep some single adults, the overall best mattress size for singles is the queen mattress. With 60 inches of width and 80 inches of length, there’s plenty of room to move around and stretch out. Furthermore, a queen size mattress can also comfortably sleep two adults, so it can accommodate a change in plans. 

Another benefit of the queen size mattress is its popularity. Being the most popular mattress size, it’s easy to find a great selection of linens and bedding to fit it. This includes mattress protectors and mattress toppers, which go a long way to protecting your investment and prolonging its life.

Of course, if you have plenty of space and want to go big, it’s not unusual for singles to own a king size mattress. After all, it’s always better to have too much sleeping surface as opposed to not having enough. A king size mattress measures 76”W x 80”L, so there’s room for a partner and even a child. If you have plans for a family, a king size mattress is a great investment. Alternatively, a California king size mattress trades a little width for extra length. At 72”W x 84”L, it’s a great choice for taller sleepers who need extra legroom. 

Other Considerations for Singles

Just because you’re single doesn’t mean you have to skimp on your sleep. If you suffer from back pain, poor circulation, or a host of other ailments, an adjustable bed base can help. They come in all sizes and levels of adjustment, so you can dial in your comfort with ease. If you plan to stay single, select an adjustable bed with a single controller. If you have plans for a partner, you might consider a split king adjustable bed, such as the PranaSleep Adjustable Powerbase 5.0, which features two twin XL mattresses (purchased separately) side by side and independent control of each half of the bed.
