Whether you’re upgrading a guest room or looking for a quality dorm room mattress, taking the time to find a supportive, comfortable mattress is a must — no matter what size you’re looking for.

A twin XL mattress has almost the exact same dimensions as a twin, but it’s slightly longer — by 5 inches — to accommodate adults, teens, and tall children. Twin XL mattresses can accommodate taller people, but they only fit one person comfortably. They also tend to be slightly pricier than twin models.

With so many mattresses on the market, settling on a final pick can be daunting. Picking and choosing a mattress requires that you do your research, regardless of whether you’re shopping for a king or twin model. In this article, we go over what you need to know when buying a twin XL mattress and showcase our top picks on the market.

Many companies offer up twin XL mattress sizes. To select our top picks, we used the following criteria:

  • Company reputation and transparency. We’re careful to select mattresses from companies that avoid making overblown claims about their products. We also only include products from brands with good reputations and transparent business practices. Additionally, we take into consideration whether companies are environmentally and socially responsible.
  • Company policies. We try to only list products from companies that offer in-home trials and extended warranties. If we do include products without these policies, we’ll call it out so you know in advance.
  • Customer reviews. Any mattresses we choose have an overwhelming amount of positive reviews. Keep in mind that a mattress purchase is very personal. What feels great for one person may feel uncomfortable for another.

Pricing guide

Twin XL mattresses are slightly longer than regular twin models, which comes with a bit of a price bump. Expect to pay at least $100 more for a twin XL than you would for a standard twin mattress. Don’t forget to factor in extra costs like taxes, delivery, setup, and accessories like bedding.

Keep in mind that air mattresses don’t usually come with in-home trial periods, but this one does have a 1-year warranty you can take advantage of.

Goldilocks quickly found the perfect mattress for her, but even she needed to experiment a little to find the right fit. Here’s what you need to consider before starting your mattress shopping adventure:

Who’s sleeping on the mattress

You need to nail down who this mattress is for. Is it a temporary solution for dorm room living? You might not want to spend a lot of money on something non-permanent. Is it for a single adult? Adults may need more support than kids because they’re heavier and typically have more back pain woes.

Mattress type

There are a ton of different mattress types out there. Your choice depends mainly on personal preference. But if you’re buying it for a guest room, you may have success with a hybrid model. Hybrid mattresses incorporate elements from foam and innerspring-style mattresses.

Mattress performance

Some mattresses have extra features that may appeal to certain buyers. If you’re a hot sleeper, for instance, opt for a cooling or temperature control mattress.

Things like motion isolation may be less critical for solo sleepers, but firmness and pressure relief are definitely important. Mattresses that are slightly soft offer more pressure relief than those with a very firm feel.

Most people find a medium-firm surface the comfiest, so if you’re outfitting a guest room, go with this middle ground firmness option.

Bed frame and bedding

Because twin XL mattresses are longer than twin models, you’ll need a specific bed frame size to accommodate the extra length. You’ll likely need to purchase a bed frame separately from your mattress. Some mattress companies sell frames along with their mattresses, but design choices are limited. You’ll also need twin XL bedding for your new mattress.

Company policies

Imagine buying a mattress and hating it. You’ll either have to stick with the uncomfortable surface or pony up extra money for a replacement. What a drag! Avoid this unpleasant outcome and try before you buy whenever you can. Many reputable mattress companies offer lengthy in-home trial periods and easy returns if you’re not satisfied.

A twin XL mattress is ideal for:

  • taller people (over 6 feet)
  • guest rooms
  • vacation rentals
  • rooms with multiple beds
  • people who want to conserve space in a bedroom

While they’re longer than regular twin mattresses, twin XL models aren’t great for couples. They’re perfect for solo sleepers who need a little extra legroom.

The only difference between a twin and a twin XL is the length. XL models are 5 inches longer than regular twin mattresses.

Buying a mattress can feel like an impossible task. There are so many twin XL options out there. Remember that even the highest-rated mattress may not be right for you. Everyone is different, and the right mattress for you is highly personal.

Whether you’re buying for your room, a guest room, or dorm room, choose an XL twin mattress from a reputable, transparent company. Also, try to find mattress companies that give you ample time to try out the product at home risk-free.
