Purple Plus Review: The Grid, Now Actually Comfortable for Side Sleepers
The original Purple Mattress had one flaw: side sleepers over 150 lb bottomed out on the GelFlex Grid. The Purple Plus fixes it with 2 inches of comfort foam under the grid. Everything Purple fans love — the buoyant, no-heat, instant pressure relief — now with a hug.
Quick take
- Best for: Side and combo sleepers 140–230 lb who want Purple‘s grid without bottoming out.
- Feel: Medium (~6/10) — grid on top of foam, instant response
- Height: 11 inches
- Price: ~$1,999 queen (frequent 20–30% promos)
- Trial / warranty: 100 nights / 10 years
GelFlex Grid — the actual innovation
The GelFlex Grid is a 2-inch layer of hyper-elastic polymer molded into thousands of columns. Under low pressure (your calves, thighs) it stays upright and pushes back. Under high pressure (shoulder, hip) the walls buckle sideways, letting that body part settle without transferring load anywhere else. No other mattress does this — memory foam compresses, latex rebounds, but only the Purple grid buckles.
Plus vs original Purple — pick correctly
The original Purple Mattress is 9.25″ and puts the grid on a hard base. Great for back sleepers under 150 lb, brutal for side sleepers over 175 lb. The Plus adds foam under the grid, so heavier side sleepers get the shoulder cradle without hitting bottom. If you’re a side sleeper, always pick the Plus over the original.
Temperature — Purple‘s actual superpower
The grid is 60% open air. No memory foam layer trapping heat. This is genuinely the coolest-sleeping mattress in its price range — noticeably cooler than a Tempur-Adapt, cooler than a Saatva Classic. If cooling is your #1 problem, Purple is the answer.
Motion isolation and edge
Motion isolation is decent but not class-leading — the grid transfers a small amount of movement. Edge support is weak; sitting on the edge to put on shoes, the grid buckles. Combo sleepers won’t care; if edge stability matters, look at the Restore Hybrid instead.
Pros & cons
Pros
- Coolest-sleeping mattress at this price
- Instant pressure relief — grid buckles under shoulder/hip
- Fixes the original Purple‘s side-sleeper problem
- 100-night trial + 10-year warranty
- Ships compressed to your door
Cons
- Grid feel is polarizing — try before you commit
- Weak edge support
- Heavier than the original Purple
- Not a great fit for stomach sleepers over 200 lb
Verdict
The Purple Plus is the best entry point to the Purple lineup for most people. Cooler than any Tempur, more pressure-relieving than any Saatva at this price, and priced under $2,000 in most promos. If you sleep hot or have shoulder pain, buy it. If you want a traditional innerspring feel, don’t.

Who the Purple Plus is for
Short version: the Purple Plus is a all-foam grid hybrid aimed at side and combo sleepers roughly 140-230 lb who want the GelFlex Grid with a softer layer beneath it. Everything below is buying guidance built on the specifications and behaviour described above – use it to decide whether this is the right model in the range before you order.
Who should skip it
- Stomach sleepers over about 200 lb, who need a flatter, firmer surface than the grid provides.
- Anyone who needs strong sitting-edge stability – the grid buckles at the perimeter. The Restore Hybrid is the better Purple for that.
- Shoppers who have never lain on a Purple grid. The feel is polarising; use the 100-night trial or try one in person first.
How to buy it without overpaying
- List price is around $1,999 queen, and Purple runs 20-30% promotions several times a year – Presidents Day, Memorial Day, July 4th, Labor Day and Black Friday are the reliable windows.
- The trial is 100 nights with a 10-year warranty. Sleep on it at least three weeks before judging: the grid feels alien for the first few nights and then stops registering.
- Skip the bundled pillow/sheet add-ons unless you want them anyway; they rarely change the net price.
Sizing, sheets and setup
Measure the doorway, stairwell turn and elevator before delivery day – mattress height and weight cause more failed deliveries than anything else. Check the sheet depth against the mattress height plus any protector you plan to use, and confirm your foundation is either a solid platform, a slatted base with gaps of roughly three inches or less, or a compatible adjustable base. Most warranties are void if the mattress sags on an unsupported frame, so an unsupported centre rail on a queen or larger is worth fixing before the mattress arrives, not after.
Purple Plus FAQ
Is the Purple Plus better than the original Purple?
For side sleepers, yes. The original is 9.25 inches with the grid sitting on a firm base, which is fine for lighter back sleepers but harsh on hips and shoulders. The Plus adds two inches of comfort foam under the grid, so heavier side sleepers get the cradle without bottoming out.
Does the Purple Plus sleep hot?
No. The grid is about 60% open air and there is no memory foam layer on top trapping heat, which makes it one of the coolest-sleeping mattresses in its price band.
What foundation does it need?
Any flat platform, slatted frame with gaps of about 3 inches or less, or an adjustable base. It does not need a box spring.
How firm is it?
Medium, roughly 6 out of 10, with an unusually fast response – the grid pushes back instantly rather than slowly conforming like memory foam.
