Purple vs Casper vs Nectar: Which Amazon Mattress Is Best?
Head-to-head comparison of three powerhouse bed-in-a-box brands available on Amazon, covering feel, cooling, pricing, and policy perks.
Brand DNA in a nutshell
Purple is famous for its GelFlex grid—a hyper-elastic polymer that’s airy, bouncy, and pressure-relieving all at once. Casper takes a balanced approach with Zoned Support foam, soft under shoulders and firmer under hips. Nectar leans into plush, slow-moving gel memory foam with an industry-leading 365-night trial and lifetime warranty.
All three brands operate official Amazon storefronts for Prime shipping. Just confirm the seller is “Purple,” “Casper,” or “Nectar” before checking out to ensure you receive authentic warranties.
Feature comparison table
Use this chart as a quick reference before digging into details.
| Brand | Feel | Construction | Best For | Price (Queen)* | Trial/Warranty |
|---|---|---|---|---|---|
| Purple | Medium-firm, buoyant | GelFlex grid + support foam | Hot sleepers, combo sleepers | ~$1,399 | 100 nights / 10-year |
| Casper | Medium, balanced | Zoned polyfoam + base foam | Side/back combo sleepers | ~$1,095 | 100 nights / 10-year |
| Nectar | Medium-firm, contouring | Gel memory foam + transition foam | Back sleepers, couples | ~$649 | 365 nights / lifetime |
Feel and pressure relief
Purple feels like floating on a supportive trampoline—the grid collapses instantly under shoulders but props up hips. Casper cradles gently without the “stuck” sensation, making it easier to switch positions. Nectar offers the deepest hug, ideal for sleepers with sharp pressure points or couples who need maximum motion isolation.
Cooling performance
Purple’s open grid wins the cooling contest, allowing constant airflow. Casper stays moderately cool thanks to perforated foams, but it can warm up under heavy blankets. Nectar includes cooling gel and breathable covers, yet the dense foam retains some heat; pair it with lightweight bedding if you sleep hot.
Edge support and motion transfer
Purple boasts reinforced edges, making the full surface usable for couples. Casper’s edges are decent but not as rigid, while Nectar’s foam rails are average yet still functional for most people under 230 pounds. In motion transfer tests, Nectar dominates, followed by Casper, with Purple showing slightly more bounce (a trade-off for its springy feel).
Policies and value
Nectar’s 365-night trial and lifetime warranty offer unmatched flexibility, especially for indecisive shoppers. Purple and Casper provide 100-night trials with 10-year warranties, which are still solid. Factor in accessory costs too: Purple sells proprietary sheets and pillows that complement the grid, while Nectar and Casper work with standard bedding.
Decision roadmap
Choose Purple if you prioritize temperature control and responsive support, Casper if you want balanced comfort with zoned alignment, and Nectar if budget and motion isolation matter most. Still unsure? Order during Amazon’s major sale events and rely on each brand’s trial to test at home.
Maintenance tips per brand
Purple’s stretchy cover should air-dry to preserve elasticity. Casper’s zip-off cover is machine washable—zip it closed before tossing in the washer. Nectar’s cover spot-cleans best, so use a breathable protector from day one.
