In a dorm, start with the housing office's rules and the bed already in the room. Many residence halls supply a mattress. So the right buy may be a protector in that bed's exact size, plus a topper only if the surface is the problem.

In an apartment, choose a mattress the student has tested. It should come in a size and format that fit the room, the stairs, the car and next year's move.

A Dorm and an Apartment Are Two Different Purchases

Dorm room Off-campus apartment
Who supplies the mattress Many residence halls supply one. The housing office says whether it can be removed or replaced. Unfurnished: you do. Furnished: the landlord, so ask what it is.
The size to confirm The bed in your assigned room, confirmed with housing What the room holds with space left for a desk and a path
What you're really buying A protector, and maybe a topper, for a mattress that stays A mattress, a base, and a way to move it next year
Who sets the rules The housing office, which can vary by school, building and room type The lease and the landlord
Getting it in Bedding travels with the luggage Doorways, stairs, the car, and whether it ships compressed or flat
Move-out Housing decides what happens to large items It moves with the student, or goes to recycling within the landlord's rules

Before You Buy Anything for a Dorm

In a dorm, permission comes before product. These four steps keep you from buying the wrong thing:

  1. Read the housing office's rules, or ask them. Find out whether a mattress is supplied, whether it can be removed or replaced, and whether toppers are allowed. These rules vary by school, building and room type.
  2. Confirm the bed size for your building and room. A packing list is general. The bed in your assigned room is what counts, so confirm its size with housing before you buy anything sized to it.
  3. Inspect the mattress at move-in. If it's stained, torn or damaged, photograph it and report it to housing. Don't cover it up with a topper first.
  4. Ask about thickness on a lofted or bunked bed. A thicker topper raises the sleeping surface higher against the guard rail. Ask housing whether a topper is allowed and how thick it can be.

Sharing a room? Agree with your roommates on who's bringing what before anyone orders.

Topper, Protector or Both

Each of these does one job. Buy each one in the size the bed actually is.

Item What it does When it's the answer What to check
Mattress protector Keeps spills and stains off the mattress under it, and can be washed Nearly any supplied or new mattress you want to keep clean That it fits the bed's exact size
Mattress topper Changes how the surface feels, softer or firmer on top The mattress is sound, but the surface feels wrong It can't restore support that has given way underneath. On a loft or bunk, housing's thickness rule comes first.
Full encasement The EPA suggests a cover that encases mattresses and box springs. It eliminates many hiding spots for bed bugs, and its light color makes them easier to see. You want the whole mattress enclosed, or you're uneasy about bed bugs Choose a high-quality encasement that resists tearing, and check it regularly for holes

Getting the Size Right in Twin, Twin XL or Full

Standard U.S. sizes are nominal (see mattress sizes). Twin is about 38 to 39" x 75", and Twin XL is about 38 to 39" x 80". Full is about 53 to 54" x 75", and Queen is 60" x 80".

Widths vary a little by maker, so check the exact model's product page.

  • Twin

    about 38 to 39" x 75"

  • Twin XL

    about 38 to 39" x 80"

  • Full

    about 53 to 54" x 75"

  • Queen

    60" x 80"

Standard U.S. mattress sizes

Twin XL mattresses are five inches longer than Twin and the same width. Still, the bed in your assigned room decides. If you're weighing the two, see twin vs. twin XL mattresses.

Sheets, toppers and protectors are sized to a mattress. So a regular Twin fitted sheet or topper can come up short on a Twin XL.

In an apartment, Full mattresses are the next step up in width, if the room still leaves space for a desk and a path. Here's how twin XL and full mattresses compare.

Choosing an Apartment Mattress You Can Move

An apartment mattress has to fit more than the sleeper. Check these before you shop:

  • The room

    Measure it, and leave space for a desk, a chair and a clear path.

  • Doorways, stairwells and the elevator

    Measure each one the mattress has to pass through.

  • The ride there

    Know which vehicle it'll travel in. Mancini's Sleepworld offers local delivery on mattresses, and their delivery page lists what's included and any options or charges for your area.

  • Compressed or flat

    Some mattresses that ship compressed arrive rolled in a box, so they're easier to carry up stairs. Once one has expanded, it can't practically go back in its box, which matters for the next move. The maker's instructions say when it's ready to sleep on. To weigh the two formats, see bed-in-a-box vs. traditional mattresses.

  • The base

    Makers set base requirements. Many compressed mattresses are designed for a solid or slatted platform or foundation. Check the apartment's frame, or look at foundations and bases that suit the mattress.

  • The lease and next year

    Match the purchase to how long the student will stay and whether the mattress moves with them.

  • Roommates and ownership

    If roommates split the cost, agree now on who keeps it.

  • The edge

    If the bed doubles as a couch in a small room, the edge gets sat on a lot. Put edge feel on your test list.

Let the Sleeper Test It

The person paying and the person sleeping may not be the same. So split the decision:

  1. The payer sets the budget and the size. Those two choices narrow the field before anyone shops.
  2. The student does the lying down. At a Mancini's Sleepworld location, one of 50+ across Northern California, the student tries two or three options in the right size. They lie in their real sleep position for several minutes, which tells more than a hand press. The parent watches the budget.
  3. Compare formats in one visit. Mancini's Sleepworld carries many brands under one roof. So the student can compare Twin XL or Full mattresses side by side, including some that ship compressed and some that arrive flat. Sit on the edge of each one, too.
  4. Ask a Sleep Specialist the fit questions. Which of the mattresses the student liked come in Twin XL or Full? Which ship compressed, and what base does each one need?

Money, Moves and Tired Mornings

Is it worth buying a good mattress for a few years of school?

Value depends on how long a mattress keeps fitting the person who sleeps on it, not on the price tag. A mattress that fits the first time and moves to the next apartment can cost less over time than a cheaper one replaced within a year.

How long the student will use it, and whether it moves with them, decide how much is worth spending. A higher price doesn't guarantee a better fit. Trying options at a few price levels, in the same size, shows whether the difference is worth paying for this student.

Will it survive moves and summer storage?

Bending, folding, weather and rough handling are what wear a mattress in a move. Cover it, keep it dry, and carry it flat or on its side as the maker's instructions say. Store it the same way over summer.

At move-out, housing or the landlord sets what happens to large items. California's Mattress Stewardship Program, overseen by CalRecycle, exists so used mattresses, box springs and futons are reused, recycled or properly disposed of. CalRecycle's page links to a finder for recycling facilities.

Should you take a used mattress or a previous tenant's bed?

Look before you accept it. The EPA advises checking secondhand furniture, beds and couches for any signs of bed bug infestation before bringing them home. Bed bugs can travel on furniture, bedding, luggage, boxes and clothing.

Is the dorm mattress why I'm tired or sore?

A mattress affects how comfortable a bed feels, and that's one part of a night. Start by counting the hours you actually slept. The NHLBI says experts recommend that adults sleep between 7 and 9 hours a night.

Watch for red flags, too. The NHLBI lists these among sleep apnea symptoms and says to talk to a healthcare provider about them:

  • Breathing that starts and stops
  • Frequent loud snoring
  • Gasping for air
  • Daytime sleepiness and tiredness

Soreness or pain is a question for your doctor.

Which Path Are You On?

If this is your situation Your next step
The dorm supplies a mattress that stays Buy a protector in the bed's size, and a topper only if the surface is the problem. See Topper, Protector or Both.
Housing allows or requires your own mattress Confirm the bed size with housing, then have the sleeper test options. See Let the Sleeper Test It.
Unfurnished apartment Run the checks in Choosing an Apartment Mattress You Can Move, then let the sleeper test.
Furnished apartment Ask the landlord what the mattress is and whether it can be swapped. Then treat it like a dorm, starting with Before You Buy Anything for a Dorm.
Move-in is days away Confirm the bed size with housing, or measure the room today. Then test in person (Let the Sleeper Test It) and check delivery for your address (Choosing an Apartment Mattress You Can Move).

Whichever path you're on, start with one thing today: confirm the bed size with housing, or measure the room.
