Casper and Purple both got their start as single-mattress DTC brands in the same 2014-2016 wave, and both have since split into full lineups — which makes “Casper vs Purple” a less useful question than it used to be. The real comparison is between Casper's 2026 lineup (which was completely renamed and restructured: the old Original is now The One, the old Nova is now Dream, the old Wave is now Snow) and Purple's GelFlex Grid tiers. They solve different problems, and which one is right depends mostly on whether you run hot at night.

The current lineups, side by side

Casper (2026 names):

• The One — around $699 (queen), all-foam, Medium-Firm (6/10)
• Cloud One — around $899 (queen), all-foam, Medium-Soft
• Dream — around $1,295 (queen), hybrid, Medium
• Snow — around $1,695 (queen), hybrid with cooling gel top layer, Medium
• Dream Max / Snow Max — around $2,175 / around $2,695 (queen), premium hybrids, Medium-Soft

Purple:

• Original Purple — around $1,399 (queen), all-foam with 2" GelFlex Grid, Medium Firm (6/10)
• Purple Plus — around $1,499–$2,898 (queen), thicker grid, Medium (5/10)
• Purple Restore — around $1,845–$3,690 (queen), hybrid with pocketed coils, Firm (7/10)
• Purple Rejuvenate — around $4,495–$8,990 (queen), flagship hybrid with the thickest grid stack

Both brands ship with a 100-night trial and a 10-year warranty as the baseline — but Purple's trial has a mandatory 21-night break-in before you can actually return it, which Casper's does not.

Where the two actually differ

Cooling. This is the deciding factor for most people. Purple's open-channel GelFlex Grid runs measurably cooler than standard memory foam — independent testing shows surface temperatures 3-4°F lower thanks to airflow through the grid, and that holds even on the all-foam entry tier. Casper's cooling is layer-dependent: The One and Cloud One have no dedicated cooling tech and sleep warm like typical memory foam, while Snow and Snow Max add a cooling gel top layer plus innerspring coils specifically to compete on this exact point. If you're a hot sleeper, Purple's advantage is real at every price tier; Casper only closes the gap at around $1,695+.

Edge support. Roughly a wash, and weak on both. Purple scores about 6.5/10 on independent edge tests. Casper's edges test as “about average” — firmer on The One (which has more traditional foam density), softer and less stable on Snow, especially for heavier sleepers sitting near the edge. Neither brand is a good pick if edge support is a priority; look at a coil-reinforced hybrid from another brand instead.

Motion isolation. Casper's foam-forward construction has the edge here — both The One and Dream “dampen movement rather than transferring it,” which matters if you share a bed with a partner, kid, or pet who moves around at night. Purple's grid, especially on the thinner-grid tiers, transfers slightly more motion than dense memory foam because the open-cell structure flexes rather than absorbs.

Feel. Purple's grid has a distinctive springy, “hovering” responsiveness that some people love and others find strange — it pushes back rather than slowly sinking the way memory foam does. Casper's foam and hybrid models contour more traditionally, with a slower, deeper “hug” feel closer to what most people expect from a foam mattress.

Comparison table

	Casper (The One / Dream)	Purple (Original / Restore)
Entry price (queen)	around $699	around $1,399
Cooling	Weak on foam tiers, good on Snow (around $1,695+)	Good at every tier
Edge support	Average, weaker on soft hybrid tiers	Weak (~6.5/10)
Motion isolation	Strong	Moderate
Feel	Traditional foam contour	Springy, grid “hover” feel
Trial	100 nights, no break-in requirement	100 nights, mandatory 21-night break-in
Durability	Foam softens over 7-10 years	All-foam tiers realistically 6-7 years

Who should buy which

Buy Casper if you sleep cool already or don't mind a warmer mattress, you share a bed and want strong motion isolation, or you want the lowest entry price — The One at around $699 is genuinely cheaper than Purple's cheapest option. The Snow is the pick specifically if you want Casper's traditional foam feel with real cooling added on top.

Delivery and setup

Both ship compressed and rolled in a box rather than requiring a truck delivery, and both can be carried upstairs by one person for queen size or smaller — a real advantage over a traditional spring mattress delivery. Casper's boxes are noticeably lighter across its all-foam tiers (The One and Cloud One), since there's no coil layer to add weight; Purple's boxes, even on the all-foam Original, tend to run heavier because the GelFlex Grid itself is dense. Expect some off-gassing smell on unboxing from either brand for the first 24-72 hours — normal for compressed foam mattresses, and it fades with airing out in a ventilated room. Full expansion takes a few hours for either brand, though Purple recommends waiting a full 24-48 hours before sleeping on it for the grid layer to settle into its final shape, slightly longer than Casper's guidance.

Buy Purple if you run hot at night — this is the single strongest reason to pick Purple over Casper, since the cooling advantage holds at every price tier, not just the expensive ones. Also a better fit if you like a more responsive, less “sinking” feel, or if you're specifically shopping the Restore/Rejuvenate tier for stronger pressure relief at the hips and shoulders.

Skip both if edge support is a priority (neither tests well) or you're over roughly 230 lbs and shopping the cheapest tiers of either brand — both companies' entry-level foam models are more likely to feel unsupportive at higher body weights; go straight to Purple Restore, Casper Dream Max/Snow Max, or a different coil-forward hybrid.

FAQ

Is Purple or Casper better for hot sleepers? Purple, clearly. The GelFlex Grid's open-channel design measurably outperforms Casper's foam tiers on temperature, and even Purple's cheapest model has this advantage — you'd need to spend up to Casper's Snow (around $1,695+) just to get comparable cooling from Casper.

Did Casper actually change its mattress names? Yes — in a 2024 lineup overhaul, the Casper Original became The One, the Original Hybrid/Nova became Dream/Dream Max, and the Wave became Snow/Snow Max. If you see “Casper Original” or “Casper Nova” referenced in an older review, look for the current names when you shop.

Which is cheaper? Casper's entry point is significantly lower — The One at around $699 versus Purple's Original at around $1,399. If budget is the primary constraint and you don't run particularly hot, Casper The One is the better value.

Does either mattress work well for side sleepers? Purple's thicker-grid tiers (Restore, Rejuvenate) are a strong pick for side sleepers because the deeper grid cushions the hips and shoulders without losing support. Casper's Cloud One (Medium-Soft) is the comparable pick on the Casper side, though it lacks Purple's targeted pressure-point cushioning.
