This sofa sleeper is made by serta. I first saw and tried it in a store, loved it very much. I searched online, a lot of places carry it but in different names. I am so glad I found it here, the best price ever. It is very well made, sturdy and comfortable. It is queen size but fitted sheet is a bit smaller for it so I use the flat sheet only. It is very heavy and requires a bit assembly. I only paid for room of choice and live on second floor. the delivery guys were so nice to do the assembly for free. Of course, I tipped them generously.
