This eight-inch, bunk-friendly mattress is available in two bunk-friendly sizes: twin and full. It features a flippable design with two firmness levels, which allows kids to grow with the mattress for years to come. The firmer side is meant for ages 3 to 7 years old, and the softer side is best for ages 8 to 12 years old. The core of the mattress is made from coils, with polyfoam on the firmer side and gel memory foam on the softer side. On top, there’s a hypoallergenic, breathable cover.

All Helix products are made with CertiPUR-US® certified foams and sustainable latex, and each Helix Kids mattress undergoes additional lead and phthalate testing to avoid any exposure to harmful chemicals.

The mattress ships in a box and is delivered to your doorstep with free, no-contact delivery. To fully eliminate any odors from your mattress, the brand recommends allowing the mattress to breathe and come to shape for a few hours before sleeping on it.

Reviewers love the flippable design, and the fact that this is a thinner mattress (8 inches), noting that it’s a great pick for the top bunk.

One of the best hybrid mattresses available today, this model offers an extensive size range plus three firmness levels (soft, medium, and firm). It’s made from memory foam and coils, with five durable layers and a cooling top, offering the perfect combination of comfort, support, and breathability. The smallest twin size starts at 55 pounds and is easy to set up on the bottom and top bunks. The perimeter of the mattress has higher gauge coils for added edge support: a must-have for bunk beds.

Brooklyn Bedding does not offer white glove set up service (or old mattress removal) at this time, but reviews do suggest that mattress set up is a cinch. The brand does recommend giving your mattress enough time (3 to 5 hours) to expand before sleeping on it.

On the fence? Take it from this five-star reviewing parent: “We purchased the short full for custom bunk beds and wanted something that was comfortable for adults. This mattress is so soft and cozy! Very impressed.”

An affordable, no fuss, memory foam mattress with single action cooling and supportive cushioning, this mattress uses CertiPUR-US® certified foam, and is a good option for stomach or side sleepers. It also has a breathable cover that’s great for hot sleepers, with minimal motion transfer—so even the sleeper on the top bunk can move around without disturbing anyone else.

The mattress is lightweight and fits bunk beds easily. With a generous 365 night trial and lifetime warranty, you’ll have plenty of time to test it out before making a final decision.

The Nectar Memory Foam Mattress is compressed into a box and is shipped to your doorstep via FedEx. Once it arrives, the brand recommends unboxing allowing your mattress to full inflate for a total of 24 to 72 hours.

Providing the right amount of thickness and comfort, reviewers say this mattress is a must for bunked sleepers . “My boys have these mattresses in their bunk beds. They said it’s the best sleep they have ever gotten. Very thick and comfortable,” touts one five-star reviewer.

Calling all eco-conscious parents: this is the mattress to shop. Not only are Avocado’s mattresses non-toxic and sustainable, but they come in three bunk-friendly sizes: twin, twin XL, and full. This is a low-profile hybrid mattress that will handle top and bottom bunks no problem. And, since all three mattress sizes are reasonable in weight (the full size is 69 pounds), moving it won’t cause a back ache.

Above all, this mattress is comfortable and supportive. It’s made from GOLS certified organic latex and individually pocketed recycled steel coils, with a breathable organic cotton and wool cover. The latex is naturally cooling, and the coils provide substantial motion control that’s great for kids who tend to move around a lot in their sleep. Keep in mind, the medium firmness level may be too firm for those who prefer a super cushioned feel. However, it’s particularly beneficial for back or stomach sleepers, who need a little extra support.

The mattress is shipped to your doorstep for free via FedEx. White glove delivery and mattress removal are available for an added cost, depending on your location. There should be no off-gassing required post-setup, thanks to the non-toxic and organic materials. It’s best to let your mattress expand for several hours before sleeping on it.

Got a loft bed that is in desperate need of a new mattress? This eco-friendly latex model is a great pick. Not only does its size range support bunks adequately, but it also utilizes sustainable and organic materials that are Control Union Certified. With three heights (9, 10, or 12 inches) and two firmness options (medium or medium-firm), you’re bound to find the perfect fit. Regardless of the height and firmness you choose, the GOLD-certified Dunlop latex gives this mattress a bouncier, more responsive feel than a memory foam model would have—but it’s still one of our top picks for a soft mattress. We’ve recommended this as a great option for couples, as well, so you may want to upgrade the whole family.

This bed arrives compressed in a box, and may require some off-gassing time to ensure odors are eliminated. However, reviewers really like that it ships quickly, is easy to box, and that it comes to shape quickly.

Shoppers love the customization options, too. Mattresses can be designed to fit your unique sizing needs. And yes, this mattress is the most expensive on this list. However, because of its high-quality materials, size range, and customization option, it’s worth the extra splurge. Besides, bedding is an investment buy, after all!

Another memory foam option, this mattress keeps things simple with three layers of memory foam that provide adequate cushioning and support for every sleeping position. All foams are CertiPUR-US®, paired with cooling gel and heat-conducting graphite to keep body temperature just right. Best of all, this bed is compatible with slatted frames, bunkie boards, and adjustable bed frames, so it’s the perfect fit for top and bottom bunks. It’s one of our favorite twin mattresses for toddlers, too.

The Tuft & Needle Original Mattress is vacuum-sealed in a box with no excess packaging. Customers have the option for professional set-up, which costs TK and includes old mattress haul away. If you prefer to set up your Tuft & Needle Mattress on your own, reviewers it’s a fairly easy process from start to finish. Just be sure to give it least 48 to 72 hours to ensure your mattress fully expands.

Parents appreciate that this mattress is the perfect fit for any bunk bed frame. “We love Tuft & Needle mattresses and now have six, one king, two queens and three fulls for bunk beds, guest rooms and our master bed rooms – comfortable cozy and great nights of sleep,” one customer writes.

This innerspring mattress offers four sizes that support bunk, platform, and trundle bed—so gone are the days of guesswork of finding the perfect bed fit. Naturepedic prioritizes safety and sustainability, with organic materials that reduce the environmental impact of synthetic pesticides and fertilizers. The materials are GOTS-, Made Safe-, and UL/GREEDGAURD-certified.

It’s also dual-sided and can support young sleepers through their growing years. One side is quilted, and the other has a smooth, waterproof surface. Depending on your child’s age and preference, simply flip the mattress over. At the core, an open innerspring design provides comfort, airflow, and temperature-regulation.

Mattress setup services are available, depending on your location. Though, if you prefer to set this mattress on your own, reviewers assure that the process is easy: simply take your mattress out of the box, remove the plastic cover, and let it expand into shape for a few hours.

Since this mattress successfully marries sustainability with support, reviewers say it’s a great bunk bed-friendly mattress overall. “The quality of the mattress is better than I expected for a top bunk mattress that needs to be thin. My son says that it is very comfortable,” one parent writes.

While most reviewers appreciate the waterproof protection this mattress provides, others give a reminder that the waterproof protection doesn’t extend to both mattress sides. To properly safe-guard your mattress, it may be helpful to add a waterproof mattress cover on top for an extra layer of protection.
