Yawnder Reviews · Legacy review restored September 2026
Archived hands-on testing
The Purple 4 is discontinued, but the original review contained extensive real testing of the deepest Purple Grid model and should not have been replaced by a tiny archive notice.
Deepest Purple Grid
The Purple 4 used four inches of Purple’s hyper-elastic grid over specialized foam and pocketed coils. That made it the plushest, deepest-contouring model in the old Purple hybrid lineup.
Sinkage and side sleeping
Our 14-pound bowling ball sank deeply into the grid, matching the weightless, cradled feel we experienced on our side. Among the old Purple hybrids, this was the strongest side-sleeper option.
Bounce without excessive motion transfer
The grid recovered almost instantly and the coil unit added true spring response. Despite that bounce, the mattress still controlled cross-bed motion surprisingly well.
Cooling
The open-grid structure allowed continuous airflow through much of the comfort layer, making the Purple 4 one of the cooler-feeling mattresses we tested in that era.
Current-shopping note

My original Purple 4 experience
I tested the Purple 4 as a plush hybrid with four inches of Purple Grid over coils. On my side, it had a deep, almost weightless cradle. Its grid recovered quickly and the springs added bounce; even with that response I found motion transfer well contained. My impression applies to the older mattress I tested, not a new Purple model.
My original 14-pound bowling-ball photo illustrates how the grid compressed under a single object. It is a visual demonstration, not a measurement of how every sleeper will sink. I also used an infrared camera to look at heat retention; a short surface demonstration does not establish a specific overnight sleeping temperature.

Who might have liked the original Purple 4?
Side sleepers: I preferred its deeper cradle for side sleeping. People who like a distinctly plush surface may appreciate that feel; body size and pressure preferences matter.
Back or stomach sleepers: A deeply cushioned surface may not be the best match for everyone who wants a flatter feel. Try the specific mattress in your usual position instead of relying on the old Purple 4 name.
Couples: I found motion reasonably controlled on my sample despite the bounce. Movement and edge feel vary by the people and model involved.
What to compare now
| Collection | What Purple currently offers | How to compare |
|---|---|---|
| Essential | Entry collection including The Purple Mattress and PurplePlus. | Check the model’s height and whether its core uses foam or coils. |
| Restore Hybrid | Current hybrid models with Purple Grid and coils. | Try the firmness and construction of each Restore model; none is assumed to duplicate Purple 4. |
| Rejuvenate Luxe | Current premium collection with additional comfort layers. | Compare height, overall feel, price and delivery terms. |

Frequently asked questions
Is Purple 4 the same as a current Restore mattress?
No. Purple’s current collections use different model names and constructions. The original 4-inch-grid review should not be treated as a test of any specific Restore.
Did the Purple 4 use coils?
Yes. The older model in our review combined a four-inch grid with a pocketed-coil support system.
Does the bowling-ball test show how I will sleep?
No. It illustrates compression in one test; a person’s weight, shape and position distribute pressure differently.
