Let me save you a return trip. The Costco pop out sectional is a decent couch, but if you're buying it blind you'll mess up the measurements. I did. Then I measured everything twice and swapped the chaise side. Here's what I learned.
The "Pop Out" Isn't the Problem
The chaise pops out. You know that. It's like a giant ottoman that slides into the frame. Smart idea, actually. But every review photo shows it in a warehouse with 40 feet of space. Your living room isn't a warehouse.
I measured my room three times before ordering. Listed footprint: about 116" wide when the chaise is locked in. Sounds fine. But the chaise sticks out 70" from the back. That's six feet of walking room gone.
Door Clearance: The Part Everyone Misses
The box isn't the couch. The couch comes in pieces. The backrests are separate. The seat cushions are separate. But the chaise section? That's one solid piece. No way around it.
My doorway is 30 inches. The chaise section is 32 inches wide. It didn't fit. Not even at an angle. I had to take the door off the hinges and still it barely scraped through. If your door is 31 or less, bring a screwdriver and plan to disassemble the door frame. Or hire someone who's done this before.
Chaise Direction: Pick It Before You Order
You can't flip it after. The pop out mechanism is made for one side. The manual says "left arm facing" or "right arm facing." Sounds simple. But if you're not sure which direction you need, sit in a chair and imagine watching TV. The chaise should be on the side where you want to put your feet up.
I picked left arm facing because it looked good in the store. Got it home. The chaise blocked the walkway to the balcony. Every morning I had to shuffle around the edge. After a week I called Costco and returned it. Reordered with the other orientation. Cost me a month.
The Fabric: Fine for Real Life, but Watch the Seams
The fabric is a textured polyester. Not velvet, not linen. It hides crumbs well. My dog's nails haven't torn it yet. But after two months, the seam on the chaise cushion where it meets the pop out is starting to pill. Not visible from across the room, but you feel it.
The seat cushions are firm. Not rock hard, but you don't sink in. If you like a soft couch, this isn't it. I've had guests say it feels supportive. I've had others say it's too stiff. Depends on your back.
The Pop Out Feature: Real Use Cases
It's not a gimmick. I use it when people come over. Pull it out, turn it into a bed. Not for sleeping, but for watching a movie with someone else. It's basically a giant footstool that can lie flat.
The bed position is fine. It's not a mattress. You need a topper if you're staying the night. I've done it once. Woke up with a stiff neck. Could be worse.
Assembly: It's Not Terrible, but It's Not Easy
Two adults, three hours. You need a socket wrench. The instructions are mostly pictures. The tricky part is aligning the pop out mechanism with the frame. The rail has to click in perfectly. I watched a YouTube video first, which helped. Don't skip the video.
What I'd Do Differently
Measure the chaise route. Not just the doorway, but every turn from the front door to the living room. I had a tight hallway that added ten minutes of sweating.
Also, measure the length with the chaise fully extended. The listing says 116". I measured 116". But when the chaise is popped out, the whole thing is 137" long. That's a foot and a half more. If your wall is 120", you can't pop out the chaise without hitting the TV stand. Check that.

The Costco Math
Price is good. Especially when it goes on sale. The return policy is the real selling point. You can break it, hate it, return it within 90 days. I've done it twice. No questions. That alone makes it worth trying.
But you need a tape measure and a plan. If you're in a tight apartment or a house with narrow doorways, brace yourself.
One Concrete Next Step
Before you click that order button, get a piece of tape and mark on your floor exactly where the couch will sit. Include the chaise extension. Then walk around it. If you have less than two feet of space anywhere, change the orientation or find a different couch. I didn't. Now I'm writing this from that couch, which fits, barely. Your call.
