After thoroughly researching the best sofa beds on the market for small spaces, I landed on this one and it did not disappoint! Very comfortable, fabric seems durable, and all cushions are incredibly firm yet comfy. Easy to pull out the bed and the mattress quality is what you would expect from a sofa bed. Once the bed was pulled out I did notice some splintering wood on the inside but no structural damage. Arms of couch just feel like wood so you definitely need a pillow to lean on - the ones provided are great and are zippered so you can swap out the covers if you want. True full size mattress about 4inch deep.
