Purple 4 King Mattress Hyper-elastic Polymer Bed

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 completed by a 3.5″ transition layer of 1.8lb density foam that provides additional pressure relief and comfort. Finally, the base layer is made of 4” of 2 lb density poly foam to add durability and structure to the mattress.

Purple uses only materials that are CertiPUR US certified and free of harmful chemicals. The majority of their foams also have CleanAir GOLD ratings, which is yet another way that Purple promotes healthy sleep. Like most beds with foam, Purple has a bit of a new mattress smell that dissipates within a day or two, especially 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 under heavier areas to offer support and create a floating sensation that many sleepers love.

Next comes a 3.5-inch transition layer of soft, responsive foam that helps prevent 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. 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

Purple Mattress is a great choice for most sleepers. The top layer is made of patented hyper elastic polymer, which provides excellent 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. Purple mattresses can be a bit too soft if you are heavier than average. The same goes for stomach sleepers. Firmer mattresses are better for them to avoid developing painful pressure points in the 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 especially beneficial for couples with differing sleeping habits. Purple mattresses regulate temperature well. The breathable cover and GelFlex Grid allow for plenty of airflow, so you shouldn’t experience 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 period, returns are allowed.

The warranty covers only structural and construction defects as well as indentations of one inch or greater depth. 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 ship free in a box and are easy to set up. After removing the plastic wrap there may be a slight smell, but it should disappear within a few days 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.
