Purple Mattress review: the grid, explained for sore backs

The Purple is the most unusual bed on our list. Its polymer grid relieves pressure in a way foam does not, and it is cooler than most. It also divides opinion.

Our verdict: best if foam feels too hot

The grid bed: a rubbery polymer lattice that collapses under the shoulder and hip but pushes back under the waist.

6–7/10 firmness · Foam bed with a 2 in GelFlex Grid on top

  • Sold by the maker's own Amazon store

The short answer: Buy it if foam leaves you hot or 'stuck', and you sleep on your side or back. Skip it if you dislike unusual textures, or want written trial terms on the listing.

Purple Mattress (Original) (Queen)

The grid bed: a rubbery polymer lattice that collapses under the shoulder and hip but pushes back under the waist.

Why it is here: A 2-inch GelFlex Grid that collapses under shoulders and hips and holds firm under the torso, with air channels running through it.

What the Purple Mattress is

A foam bed topped with a 2-inch GelFlex Grid, a lattice of hyper-elastic polymer. The maker rates it 4 out of 5 on its own scale (we read that as medium-firm) and sells it directly on Amazon as Purple Innovation.

How the grid handles back pain

Each cell of the grid buckles when pressure is concentrated (a shoulder, a hip) and stays upright when it is spread (your back, your thighs). So the grid gives where you need give and holds where you need support, without the slow sink of memory foam. Air moves through the open cells.

Who should skip the Purple Mattress

  • People who dislike unusual textures.
  • Stomach sleepers who need firm.
  • Anyone who wants a trial length on the listing; ours did not state one.
