Love this mattress
Size: Queen
Quality: G Sleep quality: Great Product, very comfortable

Bouncy
Size: Queen
I really like this mattress. It's firm but not uncomfortable. Kind of feels like a bouncy trampoline. I like the 7" height, and that if you want it softer or taller you can put a duvet insert over it and that will fill up the edges of the fitted sheet. One star docked because it's slightly smaller than queen size. There's a good inch of the box spring visible underneath. Obviously not noticeable when the bed is made. Great price as well. I would buy another one of these.

My Back Has Signed a Peace Treaty with My Bed (Finally!)
Size: Full
For years, my mattress and I had a strained relationship. It was a nightly negotiation between my aching back and a surface that seemed to actively conspire against a good night's sleep. I'd wake up feeling like I'd just arm-wrestled a grizzly bear – and lost. Then, the Serta Five Star Mattress arrived, and let me tell you, it's not just a mattress; it's a chiropractor in disguise, a cloud of tranquility, and possibly the reason I'm now a morning person (okay, cautiously a morning person). From the moment I first laid down, it was clear this was different. The "Five Star" isn't just marketing fluff; it's a promise of pure, unadulterated comfort. It strikes that perfect balance – supportive enough to keep my spine aligned (a concept I'd almost forgotten), but plush enough to feel like I'm sinking into a luxurious embrace. There's no awkward bouncing, no feeling of being swallowed whole, just a consistent, comforting firmness that makes me question why I tolerated my old mattress for so long. It's like my back finally realized what true love feels like. I'm a fairly active sleeper (read: I do a full 360-degree rotation several times a night), and this mattress handles it like a pro. Motion transfer is minimal, so if you share your bed with a human windmill like myself, they're less likely to feel like they're on a trampoline. I've been waking up feeling genuinely refreshed, without the usual aches and groans that typically accompany my emergence from slumber. It's almost unsettling how good I feel. Investing in a good mattress feels like a grown-up decision, and this Serta Five Star has proven to be an exceptionally wise one. It's not just about comfort; it's about investing in your health, your mood, and your ability to face the day without needing a team of physical therapists on standby. If you're on the fence about upgrading your sleep situation, consider this your nudge. Your body (especially your back) will send you a thank-you note.
