We had a very specific space to fit this into so the size was perfect for us. Can very comfortably sit 2 adults; probably 3 if smaller! Haven't used it as a futon yet - not a huge sleeper sofa, but we don't anticipate needing it often. Wish the back was a bit higher for sitting and reading, but overall it's a very nice sofa for the price. Material is softer than I expected and the little attached arm pillows are very soft! It was super easy to assemble. Very happy with the purchase.
