With the back-to-school season rapidly approaching, the most important buy for college students, from our point of view, is a comfy mattress topper to make dorm-issued beds feel more like home.

In fact, a new mattress topper might be the quick fix you're in need of to tailor your bed to your needs.  

A new mattress might not be part of your budget, but a mattress topper can very well be a way to make your bed feel brand-new. We've gathered the best mattress toppers for you depending on your needs and budget, that will essentially revive your existing mattress.

Many top mattress brands make a version similar to their full-sized counterparts or that will complement their lineup of mattresses as a way for you to try out their mattress without having to buy a whole new one.

We're big fans of the Avocado Green mattress, so of course, we were intrigued by their topper. The good news is, the Avocado Green mattress topper is every bit as high-quality as the full-size version. 

Why we love this mattress topper
The best part about Avocado as a company is its commitment to sustainability and quality, and it shows in literally every element of the design of this mattress topper. 

The core of the mattress is made from sustainably harvested, 100 percent GOLS-certified organic latex, which is designed to contour to your body for supreme comfort.

Want a latex mattress topper without shelling out $400+? This Sleep on Latex mattress topper is a pared-down version of the Avocado topper, and an excellent value all around, plus you can choose from three thickness options, depending on how much change you want to feel in your existing mattress.

Why we love this mattress topper
This mattress topper is made from 100 percent natural latex, which is ideal if you're looking for a product made without harsh chemicals. It's also OEKO-TEX class 1 certified, Greenguard Gold Certified, and Eco-Institut Certified.

We also love that you get to choose the firmness of this mattress topper (ranging from soft to firm) and its thickness. We like the thickest 3" option, but the thinner 2" and 1" options can save you money and, if you already have a thick mattress, may keep you from having to buy special deep-pocket sheets. 

Air channels help enhance this mattress pad's breathability, and it's made of Earthfoam latex foam — a specialized version that is meant to combine the best elements of Dunlop and Talalay latex foams, for a springy feel without too much bounce to it.

This mattress topper is spot clean only.

6. Tuft & Needle Mattress Topper

Best soft mattress topper: two inches of plush foam adds just the right amount of coziness

Specifications
Best for: Aches and pains
Sizes: Twin, Twin XL, Full, Queen, King, Cal King
Thickness: 2"
Type: Open-cell foam
Reasons to buy
+Molds to the contours of your body+Good value+Non-skid bottom+Stays cool
Reasons to avoid
-Not washable-Does not drastically transform the feeling of your bed

If your current mattress is just a little too firm for your liking, this Tuft & Needle topper could be all the added softness you need. 

What we love about this mattress topper
This two-inch-thick topper is made from responsive open-cell foam, which is designed to add softness to a firm mattress and relieve pressure points without causing overheating. At 2 inches, it will not drastically change the comfort level of your bed, or impede your existing mattresses' support. 

That said, it's still a memory foam mattress topper with all the upsides you'd expect: reactive body contouring, allergy-friendliness, and lack of motion transfer from your partner's nightly shifting. 

The other upside? It comes with several eco-friendly certifications, including CertiPUR-US, UL GREENGUARD Gold, and Intertek’s Clean Air Certification.

Are there any care instructions? 
This topper is not washable, so we recommend using it with one of our best mattress protectors.

Nestwell feather bed

7. Nestwell Double Layer Featherbed Mattress Topper

Best featherbed mattress topper: like a fluffy cloud

Specifications
Best for: Feather and down afficionados
Sizes: Twin, Full, Queen, King, Cal King
Thickness: 2"
Type: Duck down
Reasons to buy
+Great choice if you're not a fan of foam+Top layer unsnaps for easy laundering+Uses straps to anchor to bed+Affordably priced (for down) 
Reasons to avoid
-Not hypoallergenic

This sumptuous, dual-layer mattress topper from Bed Bath & Beyond's new private label, Nestwell, will soften up your mattress in no time. 

What we love about this mattress topper
Not everyone loves memory foam and latex; if you're after the best mattress topper that's made from feathers and down, this is the one. Just keep in mind that down and feather mattress toppers tend to feel cloud-like when you lie on them but will flatten during the night — so you'll need to fluff a feather bed like this back up in the morning. 

While a featherbed mattress topper won't necessarily suit those suffering from back pain, it can make very firm mattresses feel just that bit more cozy and welcoming. 

Another reason to opt for a traditional featherbed design? Temperature control, with down offering a more breathable experience that keeps you cool when you want it, and warmer when you need it. 

This Nestwell mattress topper features a 2" gusseted support layer filled with duck feather fill.  This one also features baffle-box construction to prevent the feathers and from shifting. Even better, the top layer easily snaps on and off for easy cleaning, and the feather bed itself uses straps that attach to your mattress so everything stays put.  For those seeking a hypoallergenic alternative, Nestwell also offers a fiberfill option. 

Are there any care instructions? 
The top layer actually has snaps to the gusseted support layer and can easily be undone for quick laundering in your washing machine.

Type: memory foam and down-alternative
Reasons to buy

  • For a limited time, save up to 40% off mattress toppers at ViscoSoft

This particular ViscoSoft hybrid mattress topper combines memory foam with a down-alternative topper. It's designed for anyone who loves the luxurious feel of a pillow top with the support of memory foam.

What we love about this mattress topper
Sometimes choosing between two different materials can feel like a compromise, but with a hybrid, but that's certainly not the case. This topper features a 2.5-inch gel memory foam that relieves pressure points, eliminates motion transfer, and keeps you cool, paired with a 1.5-inch down-alternative quilted pillowtop. The quilted pillowtop cover also acts as a cover to keep the topper secure with elastic straps and a fully elastic skirt to stretch over your mattress, up to 20 inches.  

It's also made in the United States with CertiPUR-US foam, and comes with a three-year warranty should the topper not perform as expected. 

Are there any care instructions? 
Actually, yes! The removable down alternative cover is machine washable. 

Plushbeds Natural Wool Topper best mattress topper

9. PlushBeds Natural Wool Topper

Best wool mattress topper: explore the benefits of wool

Specifications
Best for: those with allergies
Sizes: Twin, Twin XL, Full, Queen, King, Cal King
Thickness: 3"
Type: wool
Reasons to buy
+Made of organic, hypoallergenic, and non-toxic materials+Everything sourced made in the USA+Natural temperature regulator for year round comfort
Reasons to avoid
-Very Expensive-Not returnable due to handmade nature

Wool is highly regarded in bedding for its ability to wick away moisture and provide just the right amount of insulation. Wool is a natural temperature regulator and will keep you cool in the summer and warm in the winter. It also adds a perfectly soft layer of comfort to your bed. 

What we love about this mattress topper
At 3 inches, PlushBeds makes one of the thickest wool mattress toppers on the market, making it exceptionally plusher. Due to the natural processing, it's also incredibly soft to the touch. In addition to offering necessary pressure-relieving comfort, the wool topper has natural anti-microbial properties that prevent mold, mildew, and dust mites, something those who suffer from allergies will want to consider. 

Each wool topper is made to order, handcrafted, and sourced from farms with a sustained commitment to humane treatment and natural processing. PlushBeds also regularly takes part in third-party laboratory testing to ensure the quality, cleanliness, and integrity of the fibers.  The wool batting is encased in a 100 percent organic cotton sateen cover that is also hand-tufted. This definitely drives up the price tag of the wool topper, but it's all so worth it.

Are there any care instructions? 
The topper includes a 100% organic cotton, hand-tufted cover that can be gently "spot cleaned" with a clean cloth and a few drops of mild detergent, then left to air dry.

10. Slumber Cloud Core Mattress Pad

Best cooling mattress topper: A mattress pad with space suit technology

Specifications
Best for: hot sleepers
Sizes: Twin, Twin XL, Full, Queen, King, Cal King, Split King
Thickness: 1"
Type: mattress pad
Reasons to buy
+NASA-inspired cooling technology+Hundreds of 5-star reviews+Hypoallergenic
Reasons to avoid
-Thin, so not ideal if you're looking for added softness, or height

Technically, the Slumber Cloud Core Mattress Pad mattress topper is a mattress pad. But we had to include it for those who might be looking for a way to stay cooler at night, or who sleep on a hot mattress — for example, an older memory foam mattress that isn't constructed with any ventilation or cooling technology. If you're looking for a way to stay cooler at night, this mattress pad is one of the best options on the market.

What we love about this mattress pad
This mattress pad's viscose fabric is modeled after the technology NASA uses to keep space suits cool. Thousands of reviewers have credited this pad with reducing or eliminating their night sweats. If you don't suffer from night sweats but find your mattress uncomfortably hot, the Core pad will still help.

Here's how it all works, according to Slumbercloud: "[The fabric is made with] thousands of microscopic beads called Thermocules, and each one is set to a specific temperature. This counteracts any temperature fluctuations you might experience during the night. As your temperature increases, the beads absorb and store any excess heat away from your body to keep you cool."

In addition to stopping sweat, the pad fits mattresses up to 20" deep (so technically, you could probably use it over a more cushioned mattress topper), and it's hypoallergenic.

Are there any care instructions to follow? 
This pad is machine-washable and can be tumble-dried on low. 

How to buy the best mattress topper

plushbeds wool mattress toppper

When choosing the best mattress topper for you, there are a few factors you'll need to consider. Approach buying a mattress topper as you would a mattress. 

How thick should my mattress topper be?
The first thing to consider in a mattress topper is its thickness, particularly if you sleep on your side. For most side-sleepers, a thicker, softer mattress topper is best, because it better relieves pressure at the hips and shoulders. Meanwhile, a back sleeper looking to make his or her mattress more firm will want a thinner topper.

Note that, the thicker the mattress topper, the more likely it'll push you beyond the limits of traditional sheets and into the specialized world of deep-pocket sheets, which are needed to cover an extra-thick mattress. 

Around 2-inches is an average thickness for most mattress toppers, but the AllSwell 4” Memory Foam Mattress Topper Infused with Copper Gel is one of the thickest on our list, coming in at 4 inches of total luxury. Many consider that the thicker the mattress topper, the more transformed the bed will feel. 

What materials are mattress toppers made of?
Mattress toppers come in a wide range of materials, but those made from memory foam or body-conforming latex tend to be best for combatting back pain and offering relief from the pressure that a too-firm mattress can place on your joints. The material also influences whether the topper is hypoallergenic (key for allergy sufferers) while others will seek out materials that have been certified non-toxic to you or the environment with certifications such as OEKO-TEX, Greenguard Gold Organic,or CertiPUR-US. Finally, like you would a mattress, consider the mattresses' breathability, as some mattress toppers are better at keeping you cooler than others. 

Keep scrolling, because we'll go into greater depth about your choice of materials below. 

Will your partner like it?
What if you share a bed with someone who doesn't like the same mattress feel — whether it be soft or firm? The mattress toppers we've chosen strike a nice balance between supporting your body while still contouring to its shape, so they're likely to suit the widest range of people — regardless of whether you or your partner sleep on your back or side. 

Front sleepers should get along with these mattress toppers too but might need to swap out their current pillows for flatter ones. See all our best pillow picks — there's something there for everyone, whatever your usual sleep position.

If you and your partner share a king-sized bed, you also have the option of getting two Twin XL-sized mattress toppers and putting them together on the bed, so you can each choose your firmness and style of the topper. Just make sure those mattress toppers have non-slip bottom layers so they won't slide around beneath you. 

How it sits on the mattress 
Even if you're not sharing "split" mattress toppers, it's still worth looking for a mattress topper with a non-slip bottom layer, and/or straps that hold the topper in place on the mattress. This can also be a good solution for fixing a mattress topper in place on the best sleeper sofas. Another solution is to choose a mattress protector deep enough to cover both your mattress and your topper. 

Are mattress toppers easy to clean?
It's rare to find a washable mattress topper. Some come with washable, removable covers. But for the bulk of mattress toppers, spot-cleaning is your only option. If the ability to wash your topper is a priority, consider a mattress pad for adding softness to your bed,  

You can find out more about cleaning a mattress (or topper) in our guide. But in the meantime, we recommend using one of our picks for the best mattress protectors to protect both mattress and mattress topper against spills and accidents.

Choosing between buying a new mattress topper or a completely new mattress
Mattress toppers are great for adding extra comfort or support to your mattress or to alleviate any aches or pains. However, if your aches and pains stem from a sagging, worn down, or just flat-out unsupportive mattress, it may be time to invest in a new mattress. The harsh reality is that mattresses that have lost support or sag simply can’t be fixed with a topper because the topper will just sag in the same areas as the mattress. Other than being a band-aid fix for worn-out beds, you'd be better off putting the money spent on a mattress topper to a new mattress. Solution: one of these best mattresses.

What materials are the best mattress toppers made from?

What your mattress topper is made of determines how soft or firm it'll be, along with how well it regulates your body temperature. In general, as we already mentioned, the best mattress toppers for side sleepers or anyone suffering from joint pain is made from memory foam or latex — although hybrid mattress toppers are now available.

The following mattress topper materials usually suit back and stomach sleepers, people with joint pain, and anyone who prefers a medium-firm to firm sleep surface:

  • Memory foam: Probably the most commonly known mattress topper material is memory foam, which is made of polyurethane. It molds to the shape of your body and tends to offer excellent support. Modern memory foam is more breathable than past varieties, but sensitive sleepers may still find it hotter than other materials. 
  • Latex: Latex mattress toppers are more breathable than those made of memory foam, so they're a great choice for people who tend to feel hot at night. Latex mattress toppers are also firmer and springier than memory foam models — making them a great choice if you wish your mattress were a little more supportive. Be sure to double-check that you're buying eco-friendly natural latex. Latex tends to be more expensive than memory foam. 

Other mattress topper materials that you will come across that suit side and back sleepers, which will offer a medium to soft sleep surface, include:

  • Down/feather: You won't find many down feather toppers on the cheap, and they can aggravate allergies for some people. Sometimes the feathers can poke through the mattress cover, too. But down/feather mattress toppers regulate body temperature very well, and they offer a soft cloud of comfort atop the firmness of your mattress.
  • Fiberfill or Polyester blends: These "down alternatives" are perfect for those who love the feel of down feathers but either don't like to use animal products, are allergic, or want a more affordable product. However, these toppers are usually not as soft as others and can become lumpy over time.
  • Wool: Natural wool fleece toppers are soft, durable, and often a great choice for allergy sufferers. That said, they tend to be one of the more expensive materials for a mattress topper. 
  • Egg crate: Inexpensive, soft(ish), and thin, therefore easy to transport, mattress toppers made of egg crate foam can be perfect for those with a limited budget. But they're not known for being durable. 

What is the best mattress topper?

In case you scrolled too fast, let us reiterate how much we love the Lucid 3-inch Ventilated Gel Memory Foam Mattress Topper. In addition to its palatable price tag, the three-inch design offers just the right amount of comfort and support, a gel-infused layer of cooling gel to regulate temperatures, and a ventilated design that improves airflow for a more comfortable sleep climate. 

What is the best mattress topper for back pain? 

Tempur-Pedic Tempur supreme in kids room

If you're dealing with back pain, you'll want to seek out a mattress topper that falls in the medium to firm range to help relieve pressure and provide comfort. Mattress toppers made of memory foam, gel, or latex will offer the most relief.

Luckily, several mattress toppers on our list are excellent picks for those with back issues. For instance, Tempur-Pedic's Tempur Topper Supreme is a sure pick for those with back pain, for its unparalleled pressure relief and support, but it's also on the pricier side of the spectrum. Meanwhile, our top pick, the Lucid 3-inch Ventilated Gel Memory Foam Mattress Topper seems to do it all, keeping you cool and pain-free. 

What is the best cooling mattress topper? 

Avocado Green mattress topper

We get it, you want a mattress topper that will keep you cool and comfortable. We've even created a whole guide to the best cooling mattress pads and toppers. Traditional memory foam is known for retaining heat, but we must say, the technology has truly evolved over the years, leaving you with plenty of breathable options at a range of budgets. 

At the top of our list, we have the aforementioned Lucid 3-inch Ventilated Gel Memory Foam Mattress Topper with its cooling gel layer and ventilated design that improves airflow. 

If you're trying to avoid memory foam, consider Avocado's Organic Latex Topper. The combination of latex, wool, and cotton are a masterclass for temperature regulation, moisture-wicking, and breathability. 

Finally, though a mattress pad, the SlumberCloud Core Mattress Pad features a  viscose fabric that modeled after the technology NASA uses to keep space suits cool, so if science and technology are your M.O., or you want to banish night sweats for good, SlumberCloud proves itself as a serious contender.
