Purple 4 King Mattress Review

Purple Mattress Review

Purple’s unique grid shaped comfort layer provides a responsive sleeping 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 key differentiator is its patented Hyper-Elastic Polymer Purple Grid that covers the top layer of their mattresses. This gel-like material is temperature-regulating, breathable, and has a soft, squishy feel. It is also molded in a comfort grid, which increases airflow and helps to breathe the mattress.

This layer is complemented by a 3.5” transition layer of 1.8 lb density foam to provide additional pressure relief and support. Finally, the base layer is made of 4” of 2 lb density poly foam to add durability and structure to the mattress.

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. The base layer is a 4-inch medium-firm, high density polyfoam. This supports the rest the mattress.

All of the materials in the Purple Mattress are CertiPUR-US certified, meaning they meet standards for low emissions and chemicals. Like most mattresses, the Purple Mattress does emit an initial “new mattress” odor, but this will dissipate within a few hours when opened in a well-ventilated room.

Comfort Levels

The Purple Mattress is an excellent 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 of 4 inches of high-density poly foam provides solid support. Purple mattresses can be a bit too soft if you are heavier than average. The same goes for stomach sleepers. They need a firmer mattress to avoid painful pressure points in their lower back and neck.

This mattress is also excellent at reducing motion. Even when one of us moves around a lot, the other sleeper barely feels it. This is particularly beneficial for couples who have different sleeping habits. Purple mattresses regulate temperature well. The GelFlex Grid and breathable cover allow for airflow so you shouldn’t have too much heat retention.

The Right to Rent

Purple offers a 10-year warranty on their 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 in firmness, wear and tear, and any changes in comfort preference that occur over time. It also doesn’t cover any damage caused by misuse or neglect.

Purple mattresses ship free in a box and are easy to set up. 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.
