Purple Mattress Review

Unlike traditional foam or hybrid mattresses, Purple’s unique grid-shaped comfort layer offers a responsive sleep experience without overheating. It’s ideal for back and side sleepers of all body weights.

Like other bed-in-a-box brands, Purple ships its mattress compressed in a cylinder case. It takes a few hours for the mattress to fully decompress.

Responsive Support

Purple’s main differentiator is the Hyper-Elastic Polymer Purple Grid, which covers the top layer. This gel-like material is temperature-regulating, breathable, and has a soft, squishy feel. It’s also molded into a comfort grid design, which boosts airflow and helps the mattress breathe.

This layer is complemented by a 3.5” transition layer of 1.8 lb density foam to provide additional pressure relief and support. The base layer is made up of 4” of poly foam with a 2 lb density to provide durability and structure.

All of the materials used by Purple are CertiPUR-US certified and free from harmful chemicals. Most of their foams are also CleanAir GOLD rated, which is another way they promote healthy sleep. Purple mattresses have a slight new mattress smell, but this goes away within a few days, especially if you are in a well ventilated room.

Motion Isolation

The Purple Mattress scored 7.5/10 in our motion isolation test. This means that it limits the transference of movement between sleepers. This is an excellent score for couples sharing a bed.

The top layer of the Purple Mattress is a patented hyper-elastic polymer grid called Smart Comfort Grid. This unique material buckles underneath heavier areas to provide support and create the floating sensation that many people love.

The next layer is a 3.5 inch transition layer of soft foam that prevents sinkage. Then there’s a 4-inch base layer of medium-firm, high-density polyfoam that supports the rest of the mattress.

The Purple Mattress is made from materials that are CertiPUR US certified. This means they meet standards of low emissions and chemicals. The Purple Mattress emits an initial “new-mattress” smell, but it will disappear within a few days when opened in a well ventilated room.

Comfort Levels

Purple Mattress is a great choice for most sleepers. The top layer of patented hyper-elastic polymer offers some great pressure relief. There is also a transition layer of 3.5 inches of fast-responding poly foam that keeps the top layer from sinking too much.

The base layer, which is 4 inches of high density poly foam, provides a solid foundation. If you’re heavier than average, however, you might find the Purple mattress a little too soft for your liking. The same is true for stomach sleepers. They need a firmer mattress to avoid painful pressure points in their lower back and neck.

Motion isolation is also very good on this mattress. Even when one of us moves around a lot, the other sleeper barely feels it. This is especially beneficial for couples with differing sleeping habits. The Purple mattress also regulates temperature well. The GelFlex Grid and breathable cover allow for airflow so you shouldn’t have too much heat retention.

Warranty

Purple offers a 10 year warranty on its mattresses. The warranty is separate from the sleep trial and return policy. The company does require a 21-night break-in period to let your body adjust to the mattress. After this, returns are fair game.

The warranty only covers structural and construction defects, as well as indentations that are one inch or more deep. It excludes localized changes to firmness, wear, and any changes that may occur in comfort preferences over time. It does not cover damage caused by abuse or neglect.

Purple mattresses are shipped in a box for free and are easy to assemble. There may be a slight off-gassing smell right after you remove the plastic wrap, but this should dissipate within a few hours in a well-ventilated room. The mattress is heavy, however, so lifting and moving it will require some muscle. You’ll also need a bed frame or foundation to support it.
