The best trundle beds with mattress included in 2026 solve two problems at once: where to put an extra sleeper, and where to find a mattress that actually fits the pull-out. Buying a bundled set means no measuring the odd trundle dimensions, no hunting for a low-profile mattress, and no surprise second purchase — you unbox, roll out, and sleep. We tested the complete sets below for how smoothly the trundle glides, how comfortable the included mattresses really are, and how well each frame holds up to daily kid-and-guest use.
Below are our top ready-to-sleep trundle sets, followed by a full buying guide covering mattress types and thickness, roll-out versus pop-up mechanisms, sizing, weight capacity, and the mistakes to avoid when buying a bundle.

Why Buy a Trundle Bed with the Mattress Included
Trundle mattresses are one of the trickiest things to shop for separately. The pull-out drawer usually demands a low-profile mattress — often 5 to 8 inches thick — so a standard mattress won’t clear the frame or fit under the main bed. Buying a bundled set removes all that guesswork: the included mattresses are guaranteed to fit the drawer and slide back underneath. For occasional guests and kids’ sleepovers, a bundle is almost always the smarter, cheaper path than sourcing frame and mattresses separately.
If you’re weighing a trundle against other space-saving options, our best trundle beds guide, best daybeds, and best sofa beds roundups cover the full range of guest-sleeping solutions.
Roll-Out vs. Pop-Up Trundles
The single biggest decision is the trundle mechanism, because it determines how the second bed sits:
- Roll-out (standard) trundles pull out on caster wheels and sit at floor level. They’re simpler, cheaper, and great for kids who don’t mind a low bed. The Zinus and Harper & Bright picks use this style.
- Pop-up trundles pull out and then lift on a spring or scissor mechanism to match the main bed’s height, effectively creating one large king-width surface. The Walker Edison uses this. It’s ideal for adult couples or for pushing two twins together — see what size bed two twins make for the math.
Mattress Type & Thickness in Bundled Sets
Because the mattress has to fit the drawer, bundled trundle mattresses are almost always low-profile, ranging from about 5 to 8 inches thick. Most are memory foam or a foam-plus-innerspring hybrid. Here’s how thickness affects who a set suits:
| Mattress thickness | Typical feel | Best for |
|---|---|---|
| 5″–6″ | Firm, thin, budget foam | Young kids, rare guests |
| 6″–8″ | Medium, more supportive foam or hybrid | Teens, regular guests |
| 8″+ (pop-up only) | Closest to a standard bed feel | Adults, nightly use |
If the included mattresses feel too thin for daily adult sleep, you can always upgrade the pull-out later with a low-profile option from our best mattresses under $500 guide, as long as you match the thickness the drawer clears.
Trundle Bed Sizes & Dimensions
Almost all trundle sets are twin-over-twin — a twin main bed with a twin pull-out beneath. This keeps the footprint compact while sleeping two. Measure your room for both the closed footprint and the extended footprint once the trundle is pulled out.
| Configuration | Closed footprint | Extended footprint (trundle out) |
|---|---|---|
| Twin daybed + twin trundle | ~42″ x 80″ | ~80″ x 80″ |
| Twin platform + twin trundle | ~42″ x 80″ | ~78″ x 80″ |

Weight Capacity & Sturdiness
Solid-wood sets like the Max & Lily hold the most weight and resist wobble best, comfortably handling adults on both surfaces. Metal daybed-style trundles are rated for lighter loads and shine as kids’ beds and occasional guest setups. When we tested, the wood frames stayed dead silent under adult weight, while thinner metal frames flexed and needed every bolt re-tightened after a week of use. If the set will see nightly adult use, prioritize a solid-wood frame and a thicker pop-up mattress.

Assembly & Setup
Metal daybed-style sets have the most parts and take the longest — plan on 60–90 minutes with the ornate Novogratz on the higher end. Solid-wood platform sets like the Max & Lily are heavier but have fewer pieces. Our tips: build the trundle drawer first so you can slide it in to check clearance as you go, keep caster wheels locked until final placement, and let compressed bed-in-a-box mattresses expand a full 24–48 hours before judging comfort.
Mistakes to Avoid
- Assuming the included mattress suits adults. Most bundled mattresses are thin and firm — perfect for kids and occasional guests, less so for nightly adult sleep. Choose a pop-up set with a thicker mattress if adults will use it often.
- Forgetting the extended footprint. Measure the room with the trundle pulled out, not just closed — you need floor clearance in front of the bed.
- Buying a replacement mattress that’s too thick. If you upgrade later, match the low-profile height the drawer clears, or it won’t slide back under.
- Overlooking caster quality on carpet. Cheap wheels drag on thick carpet; look for larger or dual casters if your floor is plush.

Check price on AmazonDo trundle beds come with mattresses, or do I buy them separately?
Some frames are sold as complete sets with both mattresses included, while others are frame-only. Every pick in this guide is a bundled set, so you get the frame plus one or two low-profile mattresses that are guaranteed to fit.
What thickness mattress fits in a trundle drawer?
Most trundle drawers clear a low-profile mattress between 5 and 8 inches thick. Anything thicker usually won’t slide back underneath the main bed, which is why bundled sets ship pre-matched low-profile mattresses.
What’s the difference between a roll-out and a pop-up trundle?
A roll-out trundle sits at floor level when pulled out — simple and great for kids. A pop-up trundle lifts on a mechanism to match the main bed’s height, creating a large king-width surface ideal for adults or joining two twins.
Are the included mattresses comfortable enough for adults?
They’re best for kids and occasional guests. For nightly adult sleep, choose a pop-up set with a thicker mattress, or plan to upgrade the pull-out later with a low-profile mattress that matches the drawer clearance.
What size are most trundle beds?
The vast majority are twin-over-twin: a twin main bed with a twin pull-out beneath. This keeps the closed footprint compact while sleeping two people when the trundle is extended.
Do I need a box spring with a trundle bed?
No. Trundle sets use slatted decks or solid platforms that support the mattress directly, and box springs would make the drawer too tall to slide underneath. The included low-profile mattresses go straight on the deck.
How much room do I need in front of a trundle bed?
Plan for the extended footprint — roughly 80 inches deep once the trundle is pulled out — plus a foot or so of standing room. Measure with the trundle out, not just closed.
Can two adults sleep on a trundle bed set?
Yes, on a pop-up set where the trundle rises to main-bed height, giving a combined king-width surface. On a roll-out set the second sleeper is at floor level, which most adults find fine occasionally but low for nightly use.
