Purple Mattress is a leading bed-in-a-box company known for mattresses engineered to deliver pressure-relieving comfort and supportive sleep. Their products are built around the patented Smart Comfort Grid, which provides unique pressure relief and a cool, comfortable sleeping surface.
Every Purple Mattress features the Smart Comfort Grid, but models differ in construction. The Original Purple pairs a dual-layer foam base with the standard 2-inch Smart Comfort Grid for consistent pressure relief. The New Purple lineup upgrades the base to a responsive support coil system and offers a customizable Smart Comfort Grid in three configurations, allowing sleepers to choose a more tailored feel and support level.
Our product testers spent several weeks sleeping on the New Purple 4 mattress in a King size. Overall, they were highly impressed by the comfort and performance. Below is a summary of their experience and key takeaways about the Purple 4.
After a few weeks with the New Purple 4, testers reported exceptional comfort and notable pressure relief. The Purple 4 is the softest surface in the brand’s product range; while it may not suit those who prefer a firmer mattress, many will appreciate the sensation of gently sinking into the grid. That initial sensation can feel unusual, but most testers described it as quickly becoming a luxurious, supportive experience. They felt reduced pressure on joints and limbs and noted an overall lighter, almost “zero-gravity” feeling when lying on the mattress—an effect the company promotes and the testers confirmed in daily use.
One practical consideration: the King-size New Purple 4 is heavy. Our King arrived weighing around 200 pounds, and moving it required multiple people. When carrying the mattress up stairs, the delivery team needed an extra hand from us, underscoring that larger mattresses should be handled like big furniture—ideally with a team lift to prevent strain or accidental damage. You may need more than two people, depending on the layout and stairways.
Despite the weight and handling considerations, testers agreed the mattress delivered significantly better sleep and comfort, making it worth the effort. Many found it more difficult to get out of bed in the morning because the improved comfort made hitting snooze more tempting.
The New Purple 4 excels at pressure relief, cooling comfort, and a unique sleeping feel provided by the Smart Comfort Grid combined with a supportive coil base. It’s a strong option for side sleepers, combination sleepers, and anyone looking for a softer, contouring surface with responsive support beneath. However, sleepers who need a very firm surface may prefer a different model or a firmer configuration of the Smart Comfort Grid.
For those considering a Purple mattress, weigh the benefits—excellent pressure relief, a distinctive comfort grid, and improved sleep quality—against practical aspects like weight and the need for multiple people during setup. Testers found the trade-offs worthwhile, and the New Purple 4 stands out as a luxurious, well-engineered mattress that enhances sleep for many users.
