Three flights of stairs, one 100-pound box, and a landing that had no room to turn. That's how the Tuft and Needle arrived at my apartment. I'd read the specs—10 inches tall, 50 pounds for a queen—but I didn't think about the staircase until the delivery driver gave me that look. We got it up, barely, and I let it expand in the bedroom for a day, because the instructions say 24 hours, though it was mostly up within two. The first night I slept on it I woke up with my lower back a little sore, which surprised me because I'd read reviews saying it was medium-firm and good for back sleepers. I'm a side sleeper, so I figured that was on me. By night four, my hips were not loving it. My partner, who's 210 pounds and sleeps on his back, didn't complain, but I could see a slight sag where he lay after a week—nothing dramatic, just a shallow dip that I could feel when I rolled over. The edge support is fine; I sat on the edge to tie my shoes and it didn't cave like I expected. But here's the thing: this mattress is not for everyone. If you're under 150 pounds and sleep on your side, you might need a topper or you'll feel the firmness in your shoulder. If you're heavy, consider how much pressure you put on the foam; my partner's side dipped more than mine. The cover is a bit scratchy, but it's removable and washable, which is nice. And let's talk about the box: it's heavy, so plan for that. Also, if you have a bed frame with slats, check the gap—my slats are 3 inches apart, and that's fine, but anything wider might make the foam sag over time. I also tried the more expensive foam models before this, and honestly, for the price, this holds up. But if you have a partner with a big weight difference, you might want to read what I learned about heavy sleepers here. Also, measure your room before you buy—this is a 10-inch mattress, so it sits higher than my old one, and my nightstands look smaller now. I've had it two weeks, and the initial off-gassing smell was there for about three days, but it's gone. Would I buy it again? Maybe, if I were a back sleeper and liked firmer. But for my side-sleeping hips, I'm already looking at a plush queen or a back-sleeper pick. The deciding factor for me was the firmness—if you're okay with medium-firm and don't sleep exclusively on your side, this is a proven budget winner. But your hips will tell you if it's a no.
