A daybed with trundle gives you a sofa during the day and two beds at night, without giving a guest room over to one person who visits three times a year. The trundle bed underneath is what makes it work, and it is also where most buying mistakes happen: a trundle that will not roll out past the nightstand, or a mattress that stops it sliding back under.
This guide starts with our picks, then covers the three measurements that decide whether one will work in your room: floor space with the trundle out, trundle mattress size, and who can comfortably sleep on it. Every dimension comes from the product listings, and where a listing does not confirm a detail, we say so.
In this guide
Quick Picks: Daybeds with Trundle at a Glance
| Pick | Size | Daybed L x W | Trundle | Best for |
|---|---|---|---|---|
| Sundby | Twin | 81.7 x 41.7 in | 75.8 x 39 in, on wheels | Most guest rooms |
| Eldra | Twin, metal | 77.4 x 40.2 in | 71.1 x 39 in, locking casters | Kids' rooms, tight budgets |
| Eldenholm | Twin | 80.5 x 43 in | 75 x 39 in, pop-up | Two guests at near-equal height |
| Rosenlund | Twin | 80 x 46.3 in | Pop-up, size not listed | Built-in LED and charging |
| Astera | Full | 79.5 x 56.8 in | Confirm size | One adult guest on the daybed |
| Hedda | Queen bed | 87 x 67.2 in | 80.3 x 39.3 in sleep surface | Your own bedroom, with a spare bed |
Start with the Sundby if you want the safest all-round choice: it lists full trundle dimensions, rolls on wheels and carries the highest weight rating of the twin picks. If your guests would rather not sleep close to the floor, look at the Rosenlund or Eldenholm, our two picks for a daybed with pop up trundle.
Twin Daybeds with Trundle for Sleepovers and Small Guest Rooms
A twin daybed with trundle is the most space-efficient way to sleep two people in one room. The daybed takes a standard twin mattress, the trundle takes a second one underneath, and during the day the room only has to hold one bed-sized footprint.
Upholstered Daybeds with Trundle
Upholstered frames look more like a sofa during the day, which matters when the daybed lives in a home office or den rather than a dedicated guest room.
Sundby Twin Size Upholstered Daybed with Trundle and USB Charging Station
Choose it when you want the most complete specification and a trundle that will take a standard twin mattress.
The Sundby measures 81.7 inches long, 41.7 inches deep and 34.4 inches high. Its trundle is 75.8 by 39 inches and 10.2 inches high, on wheels, and the listing describes it as a pull-out trundle rather than a pop-up. The listing rates the daybed at 600 lbs, the highest of the twin picks here, and the frame uses slats, so no box spring is needed. A USB charging station sits in the frame for the guest's phone.
The listing confirms a twin mattress for the daybed but does not give a maximum mattress thickness for the trundle, so check that before ordering mattresses. Neither mattress is included.

Rosenlund Twin Size Upholstery Daybed with Trundle, LED and USB Charging Station
Choose it when two guests should sleep at close to the same height, and the daybed doubles as a reading spot.
The Rosenlund is 80 inches long, 46.3 inches deep and 34 inches high, with an upholstered trundle, an LED light and a charging station. Its product photos show a pop-up trundle: it rolls out, then folding legs lift it close to the height of the daybed, so the two twin mattresses sit side by side rather than one low and one high. At 46.3 inches it is also the deepest twin pick here, which can make for a deeper seat when it is used as a sofa.
The listing text does not state the trundle's dimensions, its raised height or a mattress thickness limit. Confirm all three before ordering mattresses, and remember the folding legs need clear floor to open.

Eldenholm Twin Size Wave Shaped Backrest Daybed with Trundle and USB Port
Choose it when the daybed has to look like living room furniture by day and sleep two at near-equal height by night.
The Eldenholm pairs a solid wood and plywood frame with an upholstered, wave-shaped backrest, and measures 80.5 inches long, 43 inches deep and 33.5 inches high. Its trundle is 75 by 39 inches, so a standard twin mattress fits the footprint, and the product photos show it lifting on folding legs. The listing gives an overall trundle height of 20.5 inches, which is consistent with the raised position. The daybed is rated to 300 lbs and needs no box spring.
The listing does not give a weight rating for the trundle or a mattress thickness limit. Since the mattress still has to slide under the daybed when the legs fold, confirm the thickness before you buy.

Malaren Twin Size Upholstered Daybed with Trundle and USB Charging Station
Choose it when the daybed sits under a window or a low shelf.
The Malaren is 81.1 inches long, 40.6 inches deep and only 29.5 inches high, the lowest back of the upholstered picks, so it is less likely to block a windowsill. It has an upholstered pull-out trundle, a USB charging station, and needs no box spring. The listing does not give trundle dimensions, so measure against the floor-space section below before ordering.

Metal Daybed with Trundle
Eldra Twin Size Daybed with Trundle, LED and USB Charging Station
Choose it for a child's room or a sleepover setup where budget matters more than a sofa look.
The Eldra is a black metal daybed, 77.4 inches long, 40.2 inches deep and 38 inches high, with a 12.6 inch platform height. Its trundle rolls on universal wheels that lock, and both the daybed and the trundle are rated to 350 lbs each. The listing says not to use a box spring, and it adds LED lighting and a charging station.
One detail to check: the listing gives a trundle length of 71.1 inches, which is shorter than a standard 75 inch twin mattress. Confirm with Homy Casa which mattress the trundle is designed for before you buy one.

Full Daybeds and Trundle Beds for Adult Guests
If the person sleeping on the daybed is an adult, a full daybed with trundle gives them 54 inches of mattress width instead of 38. If the guest room is also your own bedroom, a regular bed with a trundle underneath can make more sense than a daybed at all.
Astera Full Size Upholstered Daybed with Trundle
Choose it when one guest is an adult who will sleep on the daybed itself.
The Astera measures 79.5 inches long, 56.8 inches deep and 33 inches high, with a pull-out underbed trundle and no box spring required. The full-size top gives an adult guest room to turn over, which a twin does not.
The listing does not say whether the trundle is twin or full size, and full daybeds are often paired with a twin trundle. Confirm the trundle size before ordering the second mattress.

Hedda Queen Size Rattan Headboard Bed with Storage Drawers and Trundle Bed
Choose it when there is no separate guest room and the spare bed has to hide under yours.
The Hedda is a queen bed, 87 inches long, 67.2 inches wide and 45.3 inches high, with a rattan headboard, two side drawers and a roll-out trundle on casters. The trundle's sleep surface is 80.3 by 39.3 inches, long enough for a Twin XL mattress, which suits a taller guest. The main bed is rated to 750 lbs and the trundle to 250 lbs, and no box spring is needed.

For a full bed with a trundle and shelves at the head, the Roskilde pairs a bookcase headboard with a pull-out trundle in a pine frame measuring 83 by 57.5 inches. For a twin in a child's room, the Lilja takes 79.7 by 42 inches.
Trundle Bed Dimensions: How Much Floor You Need
Daybed dimensions on a listing describe the frame with the trundle tucked away. What you actually need is the floor with the trundle pulled out, because once it is out, the trundle sits beside the daybed, not under it. Add the daybed's depth to the trundle's width, then leave a walkway in front so the second guest can get in and out.
| Pick | Daybed depth | Trundle width | Both beds, from the wall | With a 24 in walkway |
|---|---|---|---|---|
| Eldra | 40.2 in | 39 in | About 6 ft 7 in | About 8 ft 7 in |
| Sundby | 41.7 in | 39 in | About 6 ft 9 in | About 8 ft 9 in |
| Eldenholm | 43 in | 39 in | About 6 ft 10 in | About 8 ft 10 in |
| Hedda (queen bed) | 67.2 in | 39.3 in or more | About 8 ft 11 in | About 10 ft 11 in |
So a twin setup needs a room about 9 feet deep, measured out from the wall the daybed sits against, to use both beds comfortably. In a smaller room, the trundle can still roll out if you clear the floor first, but the second guest will be climbing over the trundle to reach the door. Our bed sizes chart covers walkway clearances for every bed size.
Two twins side by side are not a king. A twin daybed and a twin trundle together are about 76 inches wide, the same as a king mattress. With a roll-out trundle, the second bed sits much lower, so you get two beds at two heights. A pop-up trundle, like the Rosenlund or Eldenholm, lifts close to daybed height, but there is still a seam and a frame edge down the middle, so it sleeps as two twins pushed together rather than one king.
Trundle Mattress Size: What Fits Under a Daybed
Daybed mattress size is the easy part: a twin daybed takes a standard twin, 38 by 75 inches, and a full daybed takes a full, 54 by 75 inches. The trundle mattress is where the limits are. It has to be the right length and width for the trundle, and thin enough for the trundle to slide back under the daybed with the mattress on it.
To find the maximum trundle mattress thickness, take the daybed's platform height and subtract the trundle's height. The Eldra lists a 12.6 inch platform and a 4.2 inch trundle, which leaves about 8.4 inches before you allow for the frame rail underneath the platform. A 6 inch trundle mattress is the safe choice there. Most trundle mattresses are sold in 6 to 8 inch thicknesses for exactly this reason. The same limit applies to a pop-up trundle, because its legs fold and the mattress still has to slide back under the daybed.
Length matters too. The Sundby and Eldenholm trundles are long enough for a standard 75 inch twin mattress. The Hedda's trundle takes an 80 inch Twin XL. The Eldra's listed 71.1 inch trundle length is shorter than a standard twin, so confirm before you buy. Where a listing gives neither the trundle height nor its length, ask Homy Casa customer service for both before ordering a mattress.
Pop-Up Trundle vs Roll-Out Trundle
A pop up trundle bed has folding or spring-loaded legs. Once it rolls out, it lifts to roughly the height of the daybed, so the two mattresses can be pushed together into one wide sleeping surface. A roll-out trundle stays low on its casters and works as a second, separate bed.
| Roll-out trundle | Pop-up trundle | |
|---|---|---|
| Height | Close to the floor | Near daybed height |
| Sleeps | Two people, two beds | Two people on one wide surface, or two beds |
| Best for | Kids, teens, sleepovers, siblings | Couples, older guests who find a low bed hard to get out of |
| Watch for | Mattress thickness limit | More moving parts, and the legs need clear floor |
In this guide, the Rosenlund and Eldenholm use pop-up trundles, shown on folding legs in their product photos. The Sundby, Eldra and Hedda roll out at floor level. The Malaren and Astera listings do not say, so check the photos or ask before ordering. If your usual guests are a couple who want one bed rather than two, a full daybed or a sleeper sofa may still suit them better. Our sleeper sofa guide covers that option.
Trundle or Drawers: Which Daybed Fits How You Host
The space under a daybed can hold a second bed or storage, rarely both. A trundle earns its place if you host two people at once a few times a year, or if children have regular sleepovers. Drawers earn theirs if the room is a home office first and guests are occasional, because the drawers work every day and a trundle mostly waits.
If drawers suit you better, the Soline is a tufted daybed with drawers, and the Varda adds corner bookcases and LED lighting. For a full comparison of daybeds against futons and sofa beds, see our futon vs sofa bed vs daybed guide.
How to Choose a Daybed with Trundle
Measure the Floor with the Trundle Out
Use the daybed's depth plus the trundle's width, then add 24 inches of walkway. For most twin frames that is close to 9 feet from the wall. Mark it with painter's tape before ordering.
Check the Trundle Size Before Buying Mattresses
Confirm the trundle's length, width and height on the listing, and whether it pops up or stays low. Then work out the maximum mattress thickness from the platform height. If any of those details are missing, ask before you order.
Match the Weight Capacity to Your Guests
Ratings vary widely. Among our picks, the Sundby daybed is rated to 600 lbs, the Eldra to 350 lbs on each level, and the Hedda's trundle to 250 lbs. If adults will use the trundle, look for a listed trundle capacity rather than assuming it matches the daybed.
Confirm What Arrives in the Box
None of the daybeds in this guide include mattresses. Most include slats, so no box spring is needed, and several include USB charging or LED lighting. Check the includes list so you budget for two mattresses.
Decide Where the Bedding Lives
A trundle bed needs its own sheets and pillow, and a trundle cannot store them while it is made up as a bed. Plan a shelf, closet or storage bench nearby so guests are not hunting for linens at night.
Daybed with Trundle FAQs
Is a trundle bed comfortable for adults?
A trundle bed for adults can be comfortable, with the right mattress and frame. Trundle mattresses are usually 6 to 8 inches thick, so they feel firmer than a full-depth mattress. Check the trundle's weight rating, since some are lower than the daybed above them. For regular adult guests, a full daybed or a Twin XL trundle gives more room.
What size mattress goes on a trundle bed?
Most twin trundles take a twin mattress, 38 by 75 inches, usually 6 to 8 inches thick. Some trundles are longer and take a Twin XL, and some are shorter than standard. Confirm the trundle's length and the gap between the trundle and the daybed platform before ordering.
How much room do you need for a trundle bed?
For a twin daybed with trundle, plan on about 6 feet 9 inches of floor out from the wall for both beds, plus a 24 inch walkway, so close to 9 feet in total. A queen bed with a twin trundle needs closer to 11 feet. Measure from the wall the bed will sit against.
What is the difference between a daybed and a trundle bed?
A daybed is a twin or full bed with a back and sides, designed to work as seating during the day. A trundle bed is a second, lower bed that rolls out from underneath another bed. A daybed with trundle combines the two, giving you a sofa by day and two beds at night.
Can two adults sleep on a trundle daybed?
Yes, one on the daybed and one on the trundle, as long as the trundle's weight rating suits an adult. With a roll-out trundle they sleep at two different heights. A pop-up trundle, such as the Rosenlund or Eldenholm, brings the two mattresses close to level, though they remain two twins with a seam between them.
Do you need a box spring for a trundle bed?
Usually not. Most daybeds support the mattress on slats or a metal deck, and the trundle has no room for one. Every daybed in this guide that lists the detail says no box spring is required, and a box spring would also raise the mattress above the daybed's rails.
