Twin Size Mattresses - Affordable & Comfortable - IKEA
Compared to a larger full size mattress, a twin mattress still offers plenty of space to stretch out without taking up the entire bedroom. This is especially important if two or more children share a bedroom and you need room for multiple single beds or bunk beds.

They fit, but you have to be careful to mattress thickness due to the rollover hazard. It’s listed on the TUFFING page what height/thickness is recommended. More on reddit.com

Twin mattress from IKEA?
I think morgedal is the one we have! It was the firmest one I could find for a floor bed. Within the model you can also choose firmness and we chose the firmest option. Been using it for about 9 months now and we cosleep. Both my husband and I are very happy with it! We do however have a 120 cm wide one, which is wider than an American twin but not quite as big as a double/full. More on reddit.com

Please refer to the specs for recommended weight capacity; we pair an older boy with a younger boy. A twin mattress would be fine on the bottom, however you would want to be mindful of the thickness due to head clearance; for instance, pillowtop mattresses may be too thick.

December 30, 2022 - Naturepedic 2-in-1: The normal twin size mattress is 7″ tall, and the twin trundle is still 6″ tall – more than Ikea recommends. We used the normal twin (7″), not the trundle version.

Bunk Bed Frames - Bunk Beds for Kids - IKEA
Because most bunk bed frames fit a twin size mattress , they are only intended to sleep one person each. If you opt to instead use a queen size mattress in your guest room, you can still sleep two guests but they’ll have to be comfortable sleeping next to each other.

The IKEA KURA Bed Is the Perfect Toddler Bed | Cubby
September 5, 2025 - My son was sick this past summer with adenovirus (it was horrific), so my husband bunked in his room, under the bed, for a few nights. It was nice and spacious, plus with the addition of a camping mattress beneath the duvet, it was super comfy. It’s great for sleepovers. IKEA actually sells these colorful folding mats and they fit perfectly underneath the bed.
