Pps7- way more comfortable. We lost our guest bedroom when we decided to have my mom come and live with us. The air bed always feels squishy by morning and does not feel as supportive as a platform bed which is what American leather is.. No springs etc. you can even upgrade the mattress to tempurpedic. Tinan - we got ours from room and board. You can buy the comfort sleeper system from American Leather directly or from any of the retailers who have licensed the system - crate and barrel, room and board etc. They just introduced a modular system a couple of months ago.

We have the EA Arcata sofa and I regret the purchase every day. We got all the most expensive cushion upgrades/options, and frankly, I don't think the sofa looks much better than the darn IKEA EKTORP we had when we were first married. Admittedly, my husband sprawls on it, but the cushions always look terrible. And they slide out of place very easily. I'm always having to fluff, turn, and stuff them back under the back cushions. This is our second "grown-up" sofa purchase in ::cough:: five years. And I'm anticipating having to make another very soon. Granted, these aren't the most expensive sofas ever ($1800-2k range) but...it's disappointing. We had one sofa during my entire childhood. One. And when my mother was finally tired of it, it lived in a cousin's house for eight more years. I'm not asking for 25 years, but 25 MONTHS isn't too much to ask, is it? So, I would shy away from an EA sofa where I could not flip and fluff the cushions.

@MizLizzie -- It's the Karnes at C&B https://www.crateandbarrel.com/karnes-71-queen-sleeper-sofa/s659519 This particular one does not leave the back cushions in place, however. They remove. It is still on sale. I chose it for the compact shape (width) and the ability for it to fit through a narrow door opening (more typical in a br/office). The legs come off but also it seems possible to disengage the back, if required, with some hidden bolts. The delivery people only had to remove the travel legs in order to slide it through the door (on end). If you go with the AL version, my local dealer said the annual manufacturer's sale ends soon.

Nice looking sofa! I've never seen sheets designated for sleeper sofas. What does Crate and Barrel recommend? They might make sheets for their sleeper sofas. I don't think even the older mattresses were 4". Perhaps you can get elastic clips to hold the fitted sheet in place?
