A twin mattress is the usual choice for a kid’s room, a bunk bed or a small guest room. The thickness matters most: a 6 inch model is easier to fit on a bunk, while 8 to 10 inches feels closer to a full-size bed. A twin is 75 inches long and about 38 inches wide.
The six mattresses below are all twin memory foam models from 6 to 10 inches thick. Sizes, weights, firmness and weight limits come from each product’s listing page. We have not slept on these mattresses ourselves, and we make no health claims. Weight limits are the makers’ own figures.

Twin Mattress FAQ
Is a twin the same as a twin XL?
No. A twin XL is longer, about 80 inches. These mattresses are standard twin.
Are 6 inch mattresses enough?
For kids and bunk beds, often yes. Adults may prefer 8 inches or more.
Do green tea and charcoal change anything?
They are infusions the makers describe; compare the layers and certifications.
The Short Version
For an 8 inch medium-firm option with a stated weight, the MLILY. For a four-layer 8 inch build, the EGOHOME. For a slim bunk bed mattress, the FDW or the 6 inch matcha model. For the thickest bed, the Zinus. For a washable cover, the EGOHOME charcoal.
