I bought the gray sofa with trundle to use as a seating area outside my kitchen and to add some sleeping space since we don't have a guest room. It seems nice enough quality - the fabric is not very thick, but it's very pretty. It was easy to put together with 2 people. A twin xl mattress fits perfectly in the sofa, but I had to jam it into the trundle lengthwise - and that was only possible because it was a soft memory foam mattress. So I think the trundle actually is made for a twin. My biggest complaint is how tall the bed is. I used an 8" mattress which looks perfect, but the overall sofa is so tall that me feet barely touch the floor when I'm sitting on the edge, and I'm 6' (the top of the mattress is at 26"). It's definitely more geared as a sofa that you kind or curl up on with your legs up- you can't really sit with your feet on the floor. Also, it kind of looks ridiculously large. It dwarfs the other furniture in the room - you definitely can't use a normal height side table with this!
