The quick verdict
This is a three-way extension of our head-to-head Purple vs Casper comparison. If you only care about those two, that page goes deeper on each.
The softest, most hugging feel of the three, with a lifetime warranty. Great for side sleepers who want to sink in.
Similar feel to Puffy with zoned support, usually cheaper on sale, from a brand with wider retail presence.
The gel grid: cooler and bouncier than either foam bed. The only pick here for people who overheat.
Casper and Puffy compete for the same buyer — a side or back sleeper who likes a soft foam hug. Puffy is plusher with a lifetime warranty; Casper is a touch firmer and often cheaper. Purple is for a different buyer entirely: hot sleepers and people who hate foam sink.
Side-by-side specs
| Spec | Casper One | Purple | Puffy Cloud |
|---|---|---|---|
| Construction | All-foam (Zoned Support) | GelFlex Grid over foam | All-foam (10", gel memory foam) |
| Firmness | Medium (5/10) | Medium (6/10) | Medium (5–6/10); testers say softer than advertised |
| Queen price | ~$1,095 list; ~$850–$950 on sale | ~$1,499 | ~$1,000–$1,400 list; ~$950–$1,050 on sale |
| Sleep trial | 100 nights | 100 nights | 101 nights |
| Warranty | 10 years | 10 years | Lifetime |
| Cooling | Good (AirScape foam) | Excellent (open grid airflow) | Fair (gel foam; still contouring) |
| Motion isolation | Excellent | Excellent | Excellent |
| Edge support | Fair | Good | Below average |
| Best for | Side sleepers on a budget, classic foam hug | Combo sleepers, hot sleepers, anyone who hates foam sink | Side sleepers under ~230 lbs who want a plush, hugging foam feel |
Puffy's list price is high but its sale price is almost always in effect — treat ~$1,000 as the real queen price. Casper's One sits in the same range on sale. Purple is the priciest of the three in practice.
Feel: two foam hugs and one grid
Puffy Cloud: the plushest
Puffy markets the Cloud as medium-firm. Nearly every independent tester disagrees — it reads as medium to medium-soft, with deep contouring from its gel-infused memory foam. You sink in. Side sleepers under about 230 lbs tend to love it for shoulder and hip pressure relief. Stomach sleepers and heavier people usually find their hips dip too far. Edge support is the weakest of the three; sitting on the side of the bed compresses a lot.
Casper One: the slightly firmer cousin
The Casper One is also all-foam and also contouring, but its Zoned Support layer keeps the hips from sinking as far as they do on Puffy. It's medium (5/10) and more balanced. If you like the idea of Puffy but worry about too much sink, Casper is the answer. Both sleep warmer than Purple; Casper's perforated AirScape foam edges out Puffy on cooling.
Purple: no hug at all
Purple's GelFlex Grid is the anti-memory-foam. It flexes under your hips and shoulders, holds firm everywhere else, and bounces back instantly. There's no sink, no slow response, and it sleeps far cooler than any foam. If the idea of a soft, enveloping foam bed sounds like something to escape from rather than sink into, Purple is your pick.
By sleep position and body type
| Sleeper | Casper One | Purple | Puffy Cloud |
|---|---|---|---|
| Side sleeper, under 130 lbs | Great | Good | Best |
| Side sleeper, 130–230 lbs | Great | Great | Great |
| Side sleeper, 230+ lbs | Sinks | Good | Sinks more |
| Back sleeper | Good | Great | Good |
| Stomach sleeper | Too soft | Good | Too soft |
| Combination sleeper | Okay | Best | Okay (foam feels sticky) |
| Hot sleeper | Fair | Best | Fair |
| Couples (motion) | Excellent | Excellent | Excellent |
| Sits on the edge of the bed | Fair | Good | Weak |
Warranty and trial: Puffy's big advantage
- Puffy: 101-night trial, lifetime warranty.
- Casper: 100-night trial, 10-year warranty.
- Purple: 100-night trial, 10-year warranty.
A lifetime warranty on an all-foam mattress is unusual and it's Puffy's best selling point. The fine print matters — sagging thresholds and prorating apply — but it's still meaningfully better coverage than 10 years. If you're choosing between Casper and Puffy and the price is similar, the warranty can reasonably decide it.
Price and where to buy
All three land around $1,000–$1,500 for a queen depending on the sale of the week. Casper and Puffy are frequently within $100 of each other. Purple discounts less and tends to be the most expensive in practice. Casper and Purple are on Amazon; Puffy is primarily direct.
Puffy Cloud
Deep-contouring gel memory foam, excellent motion isolation, lifetime warranty. Best for side sleepers who want to sink in.
Casper One
Similar soft feel with zoned support to limit hip sink. Frequently the cheapest of the three on sale.
Purple Mattress
GelFlex Grid: no foam hug, maximum airflow, instant response. The pick for hot and combo sleepers.
Who should buy which
Puffy Cloud if you sleep on your side, weigh under ~230 lbs, want the softest option, and value a lifetime warranty. Casper One if you want that same foam feel with a bit more support and the option to buy through Amazon or a big-box retailer. Purple if you sleep hot, toss and turn, or simply don't like memory foam.
