You can ignore the "limited time offer" warning on Puffy's website — the Puffy Deluxe is pretty much always 15% off. This means you'll regularly get a queen size for $245 (value: $288). You'll also get some generous extras, including a 101-night sleep trial and a lifetime warranty (practically unheard of for even the best memory foam mattress toppers).

Meanwhile, the Casper Comfy Mattress Topper is not currently on sale over at Casper, but when it is, it's typically 10% off. They also offer free shipping and returns, a five-year warranty and 30-night sleep trial.

This is just $5 more than the Puffy Deluxe, but we should warn you it only comes with 30-day returns (no official trial).

Puffy Deluxe vs Casper Comfy Mattress Topper: Design and materials

• The Puffy Deluxe has an elasticated removable, machine-washable cover
• The Casper Comfy has a zippable, removable cover, but it's spot-clean only
• The Puffy Deluxe is hypoallergenic, while the Casper Comfy is dual-layered

The Puffy Deluxe is kind of designed like a fitted sheet, with a 2.5" layer of memory foam at the top. It has an elasticated skirt that makes for a sturdy, snug grip, and it's removable and machine-washable for an easy clean. It's made from Bamboo rayon and polyester, and the materials are hypoallergenic, too.

The Casper Comfy Topper also has a removable cover, but it's spot-clean only. It's made from a soft polyester-blend that can be zipped up, and it's designed to be breathable for temperature control. It features 3" of perforated memory foam, which is dual-layered: the top layer is for plushness whole the bottom layer is more durable and stable.

Puffy Deluxe vs Casper Comfy Mattress Topper: Support and Comfort

• The Puffy Deluxe is perfect for both side and back sleepers
• The Casper Comfy offers plush comfort for side sleepers
• The Puffy has a tendency to sleep warm, but the Casper stays cool

We tested the firm version of the Puffy Deluxe for our Puffy Deluxe Mattress Topper review, and found the topper to be comfortable and supportive enough for both back and side sleeping.

Despite the firm label, it has a classic body-hugging memory foam feel, and thanks to it's elasticated design, it doesn't shift even if you're a restless sleeper. However, it's a little too soft for heavyweight sleepers, and hot sleepers may find it sleeps warm.

Meanwhile, when testing the Casper Comfy Topper for our Casper Comfy Mattress Topper review, we found the plush bed topper to be strictly a side-sleeper topper thanks to its ultra-soft memory foam feel. It also sleeps incredibly cool, too, thanks to its airflow-boosting perforated foam and breathable cover.
