We track the Queen PurpleFlex GelFlex foam mattress.
Pick one or more traits above and we will show the strengths and watch-outs that matter for this mattress.
Choose PurpleFlex if you want the cheapest current Purple Grid mattress and prefer a firmer, buoyant feel. Skip it if you need plush side-sleeper cushioning, calm motion isolation, strong edges, or a fee-free return or exchange path.
Pressure-relief testing was mixed, with very shallow sinkage and limited comfort depth. The Grid gives the surface more give than flat firm foam, but sensitive side sleepers should compare a softer or thicker Purple model.
Shallow sinkage and the thin 8-inch profile create a firm, lifted surface. That is more promising for many back sleepers than for side sleepers who need deeper shoulder relief.
Motion-transfer testing scored 7.1/10, with peak-to-peak acceleration 12.47–12.97 m/s². That is good rather than exceptional isolation, so very light sleepers may prefer a calmer foam surface.
A fixed 12 lb load creates the impact while an accelerometer records the movement that crosses the mattress.
Cooling testing was good, and the 2-inch GelFlex Grid is the main cooling-relevant material. Very hot sleepers still have stronger Purple options to compare.
Edge testing was mixed, with usable sitting support but mediocre lying-edge stability. This is not the best Purple choice for edge-focused shoppers.
We measure seated compression, then check how secure the surface remains while lying directly along the edge.
Response testing showed very quick recovery, and bounce was high enough to make repositioning easy. This is one of the clearest strengths of the mattress.
The official 8-inch construction uses a thin comfort system over a solid foam core, making it simpler and less substantial than Purple's higher tiers. A strong initial odor cleared in about 4.07 days. Limited owner reports support a Good aging outlook but do not justify a Strong durability rating.
The score uses the policy terms shown in the Fine Print Check below. Models governed by the same terms use the same policy inputs.
Purple positions PurpleFlex as a firm, lower-profile GelFlex Grid mattress.
Testing supports the broad role, with pressure around 6.4/10 and support around 8.2/10, but body weight and position still decide fit.
The firm, shallow build is best suited to back and combination sleepers; pressure-sensitive side sleepers should compare the deeper PurplePlus.
Purple emphasizes airflow through the Grid and quick response.
Cooling scored 7.8/10 and ease of movement scored 10/10.
Combination sleepers get the clearer benefit; very hot sleepers have stronger Purple cooling options to compare.
Purple promotes a 100-night trial, 10-year warranty, and current sale price.
The final Queen price matters alongside the return, exchange, pickup, and channel-specific terms, including the possible $150 transportation charge.
Confirm the final price and purchase-channel return terms before ordering, especially if the distinctive Grid feel is new to you.

Configuration evaluatedBrand label Firm · measured Medium-Firm 6.5/10 · 8-inch profile
SoftFlex cover98% polyester and 2% spandex top panel
The stretch cover lets the Grid flex under the sleeper. Purple lists a non-slip bottom panel made from 74% polyester and 26% acrylic latex. As the surface textile, it chiefly affects the initial hand feel, moisture movement, and how readily heat leaves the sleeper; it supplies little of the mattress's deep support.
Why it matters: Across the PurpleFlex Mattress, cooling testing scored about 7.8/10. Treat the cover as one part of thermal comfort rather than proof that the mattress will stay cool for every sleeper.
GelFlex GridHyper-Elastic Polymer
2.0"The 2-inch Grid creates the buoyant Purple feel and airflow. The flexible grid yields under concentrated load while less-loaded areas remain raised, combining pressure redistribution with open channels through the comfort layer.
Why it matters: For the PurpleFlex Mattress as a whole, pressure-relief testing scored about 6.4/10. Its feel is more distinct than conventional foam, so the recorded sinkage and pressure result are more useful than assuming every sleeper will like the grid sensation.
Support foamPolyurethane foam
6.0"The 6-inch support layer gives PurpleFlex its lower-profile, firmer Essential feel. This foundation resists deep compression and keeps the comfort layers working on a stable plane; it is not intended to provide the mattress’s initial plushness.
Why it matters: In the finished PurpleFlex Mattress, the GelFlex Grid gives the mattress a more resilient comfort material than basic foam. Its thickness and material quality are more relevant to long-term shape retention and bottoming-out resistance than to surface softness.
Fire barrierFiberglass-free fire sock
Purple lists a fiberglass-free fire sock that is not chemically treated. This is a safety component rather than a comfort layer; it is intended to slow flame spread without supplying meaningful cushioning or support.
Why it matters: For PurpleFlex Mattress shoppers, its exact composition matters most to shoppers who are avoiding glass-fiber fire barriers, while its condition matters because a damaged barrier should not be handled like ordinary upholstery.
