Twin XL Size Mattress Guide – Dimensions, Top Brands & Models, Sheets

Date:

Share:

A twin XL size mattress is an excellent option for tall teenagers, and college students in dorms, or guest rooms. Measuring 38 x 80 inches, twin XL mattresses are 5 inches longer than a standard twin size. The extra length allows tall individuals to stretch out fully without their feet hanging off the edge.

In this comprehensive guide, we’ll cover everything you need to know about twin XL mattresses. From dimensions and ideal users to key components, leading brands, and where to buy sheets – consider this your one-stop shop for twin XL mattress information.

What Makes Twin XL Mattresses Different?

Twin XL mattresses have the same width as a standard twin at 38 inches wide. However, twin XL mattresses are 80 inches long compared to 75 inches for a regular twin.

That extra 5 inches of length can make all the difference in comfort for tall users. It allows them to stretch out fully without worrying about their feet hanging off the bed.

Here’s a visual comparison of twin vs twin XL mattress sizes:

Twin XL80 inches38 inches3040 square inches

As you can see, the twin XL offers 190 extra square inches of sleep surface area.

Who Are Twin XL Mattresses Best Suited For?

Due to their longer design, twin XL size mattresses are ideal for:

  • Tall teenagers – Once kids hit their growth spurt, regular twin sizes quickly become too small. Twin XL mattresses allow gangly teens to sleep comfortably.
  • Tall college students – Twin XL is a popular dorm room size since it fits students over 6’ tall while using less floor space.
  • Guest rooms – Perfect for tall visitors so they can stretch out fully. More comfortable than cramped twin beds.
  • RV mattresses – RV bunk sizes are often longer and narrower, suiting twin XL mattresses well so occupants can fit.

While twin XL mattresses offer 5 more inches than twins, they still may not be long enough for very tall adults over 6’ 4”. Couples sharing a bed may also find the narrow 38” width to snug.

Pros & Cons of Twin XL Mattresses

Pros

  • Fit tall users better – The bonus length lets users over 6’ tall stretch out fully. No more dangling feet off the edges!
  • Perfect for small rooms – Great for dorms, kids rooms, and guest rooms since they take up less floor space than larger mattress sizes.
  • Cost-effective – Among the lower-priced mattress sizes. More affordable than queen or king sizes.
  • Take up less space – Easy to move through tight spaces and doorways. Fits better in rooms with limited square footage.

Cons

  • May still be too small for very tall adults – Those over 6’ 4” may prefer larger XL twin, full XL, or California king sizes.
  • Limited selection – Fewer twin XL mattress options on the market compared to more popular sizes like queen and king.
  • Not ideal for couples – The narrow 38-inch width doesn’t comfortably fit two sleepers. Better for single occupants.
  • Harder to find sheets – You’ll need specifically sized twin XL sheets for the 80” length instead of standard twin sheets.

Now that we’ve compared the pros and cons, let’s look at what makes up a twin XL-size mattress.

Important Components of a Twin XL Mattress

Twin XL mattresses share similar designs and components with other mattress sizes. Key elements include:

Support Core

The support core forms the base layer of a mattress. It provides shape, structure, and durability. Common types include:

  • Innersprings – Coil systems made from tempered steel offer bounce and airflow. More budget-friendly option.
  • Latex foam – Provides conforming support with some buoyancy and responsiveness. Naturally antimicrobial.
  • Memory foam – Known for superior pressure relief. Cradles the body’s natural contours.

Comfort Layers

The top comfort layers affect how plush and cushiony a mattress feels. Types of comfort materials include:

  • Memory foam – Molds closely to the body to alleviate pain points for side sleepers and heavier users.
  • Latex foam – Bouncy, responsive latex offers cooling airflow and gentle contouring.
  • Polyfoam – Basic petroleum-based foam adds some plush padding at an affordable price point.
  • Specialized foams – Options like gel memory foam, copper-infused foam or phase change materials regulate temperature.

Mattress Height

The total mattress thickness ranges from 5” slim models up to 18” luxury models. Bulkier mattresses tend to have more support and comfort layers for advanced pressure relief and support.

Coil Count vs. Foam Density

For mattresses with innerspring cores, the coil count indicates durability and support levels. Standard counts are 500-1000 coils for most sleepers under 230 pounds. Heavier users may benefit from 1500+ coil counts.

For all-foam mattresses, pay attention to foam density instead, measured in PCF (pounds per cubic foot). Higher-density foams above 4 PCF tend to outperform lower-density foam comfort layers.

Edge Support

Quality twin XL size mattresses reinforce the perimeters to allow full use of the sleep surface without sagging when getting in and out of bed. Models with strong edges prevent sleepers from feeling like they might roll off.

Now that you understand key mattress components, let’s explore the top features and factors to weigh with twin XL sizes specifically.

Key Considerations When Buying a Twin XL Mattress

Keep the following criteria in mind when picking out the ideal twin XL mattress for your needs:

Intended Use

Consider who will be sleeping on the twin XL mattress. Key questions include:

  • Is it for everyday personal use or a guest room? Guests likely only sleep on it occasionally so you may not need the highest-end model.
  • What age is the intended sleeper? Kids and teens may appreciate fun color or design options. Adult guests may prefer plusher surfaces for their joints.

The intended user can guide your priorities in terms of support, quality, lifespan, and special features needed.

Mattress Type

The three main mattress types each have their own pros and cons. Think about your priorities in areas like budget, sleep style, preference for springs vs foam, cooling needs, and ease of movement.

Innerspring – Bouncy and breathable. More firmness options. Good for combination side/back sleepers on a budget.

Memory Foam – Cradling pressure relief. Great for side sleepers and sharp pressure points. Can retain some heat.

Latex – Responsive support with bounce. Contouring yet easier movement than memory foam. Has natural cooling.

Firmness Level

The right firmness level helps keep your spine properly aligned as you sleep. Softer surfaces allow more sinking in and pressure relief while firm options offer more pushback support.

Back and stomach sleepers often prefer medium to medium firm (5-7 on the 1-10 scale). Side sleepers need extra cradling so they may enjoy softer mattresses in the medium soft to medium range (3-6).

Durability

Consider how long you expect the twin XL mattress to last before needing replacement. The average is 6-8 years for mid-range options with 10 years for high-end investment pieces. Rotate your mattress regularly to promote even wear.

For college kids, you likely just need a mattress to last their 4 years of school without getting too beaten up and lumpy. Guest room mattresses see less frequent use so have less wear and tear.

Special Features

Any special needs or “nice to have” extras? For example:

  • Cooling options like copper or gel infusions, breathable coil designs, and phase change materials help regulate temperature for hot sleepers.
  • Eco-friendly components like plant-based foams and renewable fabrics appeal to the environmentally conscious.
  • Antimicrobial protection inhibits odor, bacteria, mold, and mites – great for allergy sufferers.
  • Zoned support offers reinforced areas for the hips/shoulders and reinforced edges against sagging.
  • Easy movement is key for those recovering from injury or with mobility issues.

Once you have your criteria and preferences mapped out, let’s explore top-rated twin XL mattresses.

Caring For Your Twin XL Mattress

Taking good care of your twin XL mattress ensures it stays comfortable and lasts its full lifespan of around 8 years. Follow these tips:

  • Use a mattress protector from day one to shield against spills, stains, and sweat. Look for waterproof, breathable covers that don’t change the mattress feel.
  • Rotate your mattress head-to-toe every 6 months to promote even wear and prevent permanent body indentations.
  • Spot clean messes immediately with a damp cloth and mild detergent if needed. Blot gently instead of scrubbing.
  • Vacuum the mattress surface monthly using an upholstery brush head to suck up dust and allergens.
  • No flipping is required for one-sided twin XL mattresses, but you can flip two-sided types.
  • Replace your mattress when you see sagging, feel coils or rods through the surface, or wake up with increased aches and pains.

Next, let’s look at the essential bedding accessory – twin XL sheets.

FAQs About Twin XL Mattresses

Let’s wrap up this comprehensive guide by answering some frequently googled questions about twin XL mattress sizes:

What are the dimensions of a twin XL mattress?

Twin XL mattresses measure 38 by 80 inches for a total size of 30 by 80 inches. They’re the same width as a regular twin but 5 inches longer.

Are twin and twin XL sheets the same size?

No, due to the extra length standard twin sheets won’t properly fit a twin XL mattress. You need specifically sized twin XL sheets for full coverage.

Is a twin XL bigger than a full-size mattress?

While a twin XL has 5 more inches of length than a twin, it has less width than a full at only 38 inches across. Full mattresses are 54 inches wide so they offer more surface area for couples or solo sleepers who toss and turn.

What size sheets fit college dorm beds?

Most college dorm room mattresses are twin XL, measuring 36 by 80 inches long. So opt for well-fitting twin XL sheets sized for the longer dorm mattress length.
