Casper’s The One Mattress Is Consumer Reports’ Top Pick — I Put It To The Test

Today, our editor is reviewing The One Mattress by Casper — the brand’s top-selling, all-foam model. Keep reading for the full breakdown: the product details, first impressions, and the final verdict…

The Product

The One Mattress is Casper’s best-selling all-foam model, designed with a medium-firm feel. It’s made up of three layers:

• A breathable comfort layer to help regulate temperature
  
• Cradling memory foam to support spinal alignment and comfort
  
• A durable foam base for long-lasting structure and support
  

Casper mattresses come with free delivery in as little as 2–8 business days, a 100-night risk-free trial, and a 10-year warranty. The One is also Consumer Reports’ top-rated all-foam mattress of 2025*. The queen price is $799 with flexible finance options, making it Casper’s most affordable all-foam option.

First Impressions

I’ve always wondered if big mattress brands like Casper are really worth it, or if they’re just good at marketing. My old mattress was… fine. A little lumpy, but fine. Spending hundreds of dollars on a new one felt like a gamble — especially when so many brands claim to have the “perfect” mattress.

What finally made me seriously consider The One was its Consumer Reports ranking and the 100-night risk-free trial. I figured worst case, I could send it back if it didn’t live up to the hype.

When it arrived, I loved how quickly it expanded out of the box. The cover is soft and smooth, and the mattress has a bit more bounce than I expected from foam. But I knew I’d have to actually sleep on it for a while to see if it was worth keeping.

The Verdict

After a month with The One, I get it. The mattress has that perfect balance of softness and support — my shoulders and hips sink in just enough, while my back stays aligned. Whether I’m on my side, back, or stomach, The One stays super comfortable. It’s genuinely made for any kind of sleeper. I wake up without stiffness, and I’m sleeping deeper than I have in years.

I also tend to overheat at night, but the breathable foam layer keeps things chill, literally. Now I drift off quickly and wake up refreshed, like my bed is working with me — what a dream.

For me, The One has gone from “let’s just test this out” to “I never want to sleep on anything else.” Starting at only $599, The One is the smartest investment I’ve made since moving into my new place. Casper — and The One Mattress — is the perfect sleep solution I didn’t know I’d been missing.
