Futon: A mattress on a foldable frame that converts from a sofa to a bed.
Sofa Bed: A traditional sofa with a hidden mattress that folds out, often more bulky and complex.
Yes, standard sheets, blankets, and pillows can be used, but you may need deep-pocket sheets for thicker futons.
No, futon beds do not require a box spring. The mattress sits directly on the futon frame.
Most futons have a simple folding mechanism: lift the backrest and push it down to convert it from a sofa to a bed, or vice versa.
Sleeping: 6–8 inches.
Dual-purpose (sofa + bed): 5–7 inches.
Sofa-only: 4–6 inches.
Your futon should be flipped about every seven to ten days for the first 6-8 months, then once a month.
