Edge support would be perfect if the mattress was a few inches taller.

A lot of the positive features of this mattress can be attributed to the GelFlex Grid.

Through motion isolation tests, it was clear that the PurpleFlex absorbs movements very efficiently, too.

Read on to see the results of my testing and my nightly experience sleeping on the PurpleFlex mattress.

The design starts with a breathable cover that can be removed, but not machine-washed.

The next layer is perhaps the most interesting a two-inch GelFlex grid.

The outlines of the grid can be felt through the top cover.

Running around the perimeter of the Grid is a foam border, designed to bolster the edge support.

Purple

The PurpleFlex is the cheapest of three Essential mattresses at Purple, sitting beneath thePurple OriginalandPurple Plus.

I’d rate it about a 7.5 out of 10 on the firmness scale, with 10 being rock-solid.

I could even feel it when lying on the mattress.

Purple NewDay Mattress - Full

It did not bother me as I slept.

A 15lb dumbbell only sunk half an inch when I placed it in the center.

The PurpleFlex is best suited to back and stomach sleepers.

Purple NewDay Mattress - Queen

A friend who is about 5' 2" and weighs 100lbs also slept on the mattress.

She settled onto her back and fell asleep immediately, not waking once in the middle of the night.

She also felt the GelFlex Grid and judged the firmness level to be a 7 out of 10.

Purple NewDay Mattress - King

Interestingly, she found sleeping on her side felt equally as comfortable as sleeping on her back.

I never once got hot.

It only wobbled slightly.

I couldn’t feel her move at all.

(On most mattresses, it sinks an inch.)

Did it make getting in and out of bed more difficult?

Do I fear slipping off the bed when sleeping?

But does it knock my opinion of the edge support from perfect to ‘good?’

The PurpleFlex mattress, however, came in a purple plastic bag with handles.

All the reviewers agree whether they praise or dislike the mattress that the PurpleFlex is a firm mattress.

There were a few complaints that the mattress was not thick enough by people with larger bodies.

Should you buy the PurpleFlex mattress?

Trust me when I say that you’re going to enjoy uninterrupted sleep despite your fidgety partner.

You prefer taller mattresses:At only eight inches tall, the PurpleFlex mattress is a thin mattress.

Some nights it was lower than that.
