Firmness
Measured data6/10 (medium-firm)
A notch firmer than the “medium feel” on the Costco and Purple listings. The grid makes it feel springy rather than dense.

Purple Renew Mattress ReviewA PurplePlus in a Costco cover.
This Purple Renew mattress review covers the 11-inch gel-grid bed Costco has stocked nationally since December 2025. Purple says it differs from the PurplePlus only by its two-tone cover. NapLab measured it at 6 of 10: cool, quiet and quick to rebound, but a poor match for side sleepers and anyone who sits on the edge.

Quick Verdict
Is the Purple Renew worth buying?
Only if you already want the Purple grid and you sleep mostly on your back. NapLab measured 6/10 firmness, 1.98 in of sinkage, fast heat release and a 0.3-second recovery, and rated back and stomach sleepers from 150 to 250 lb a “maybe”. It rated side sleepers “no” at every weight and measured a soft 5.50 in seated edge. The case for the Renew over the PurplePlus is the channel: $1,299.99 for a queen on Costco.com on 7 November 2026, delivered and set up, against $1,899 for the Renew and $1,699 for the PurplePlus on purple.com, with Costco’s return policy in place of Purple’s 21-night minimum.

Best for
- • Costco members who already know they like the Purple grid: the same build Purple sells as the PurplePlus, with a warehouse return policy instead of a 21-night minimum.
- • Hot sleepers: NapLab measured an 89.4 °F peak, slightly under its 89.7 °F average, and the surface shed 7.9 °F in the first minute against a 4.8 °F average.
- • Combination sleepers who hate feeling stuck: full recovery measured 0.3 seconds, the top response score in NapLab’s scale.
- • Back sleepers from about 150 to 250 lb who want a floating, low-sink surface (1.98 in measured sinkage) and can live with a NapLab “maybe”.
Avoid or test carefully if
- • You sleep mostly on your side. NapLab recorded hip pressure above 2.0 PSI on several side-sleeping maps and rates side sleeping “no” at every weight.
- • You weigh under about 150 lb. NapLab marks every position “no” for that band; a light body barely engages the grid.
- • You sit on the edge to dress or share a narrow bed: seated edge compression measured 5.50 in against a 4.06 in average.
- • You want coils. This is 9 in of polyurethane foam under the grid; the Purple bed with springs is the Restore Hybrid line.

Where to buy it
One build, three queen prices
Purple launched the Renew at $999 for a queen when it reached 450 warehouses in December 2025. Eleven months later, the three listings that sell this layer build spread about $600 apart for the same size. Prices below were read on 7 November 2026; Costco warehouse prices are set locally and may differ from Costco.com.
| Listing | Queen price | Terms that change |
|---|---|---|
| Costco.com — PurpleRenew 11" | $1,299.99 | Membership required. Delivery, setup and haul-away included. Costco satisfaction guarantee; return to any warehouse. |
| purple.com — PurpleRenew® | $1,899 (no sale shown) | 100-night trial, 21-night minimum. Free shipping, boxed. Refund net of discounts and transportation deductions. |
| purple.com — PurplePlus® | $1,699 sale ($2,099 list) | Same build per Purple, standard cover. Same purple.com trial and return terms. |
The odd result is that purple.com prices its own Renew above the PurplePlus it says is the same mattress. If you are buying from Purple, the PurplePlus on sale is the cheaper route to this build. If you have a Costco membership, the Renew is cheaper again, and the price includes white-glove delivery, setup and haul-away, where purple.com ships the bed free in a box.
Comparable performance matrix
What the evidence says—and does not say
Each result is labeled by evidence type. A measurement is not converted into a 10-point rating, and an untested metric stays unscored.
Pressure relief
Measured data1.98 in sinkage; peaks above 2.0 PSI on several side maps
NapLab calls the pressure relief fair and the contour slight. Shallow sinkage keeps back and stomach sleepers level, but side sleepers’ hips produced the high readings. That cuts against Purple’s “shoulder + hip pressure relief” line.
NapLab measurementCooling
Measured data89.4 °F peak surface temperature (average 89.7 °F)
Only 0.3 °F under average at the peak, but the open grid released heat fast: 7.9 °F in the first minute against a 4.8 °F average. NapLab scores cooling 9.0, the bed’s strongest category.
NapLab measurementMotion isolation
Measured data8.26 m/s² acceleration, 1.01 s duration
Slightly better than NapLab’s 8.74 m/s² average, though the motion lingers about a second. Expect a little grid jiggle rather than a dead stop.
NapLab measurementResponse / bounce
Measured data0.3 s full recovery; 8.87 in total bounce
The grid snaps back almost instantly (average 1.0 s), which makes turning over easy. Total bounce sits a little under NapLab’s 9.31 in average.
NapLab measurementEdge support
Measured data5.50 in seated compression (average 4.06 in)
The weakest measured result. NapLab reports the grid collapsing at the edge under seated load despite the foam perimeter, and rates lying-edge support only fair.
NapLab measurementNoise
Measured dataMinimal — top score in NapLab’s noise category
No coils to creak. No decibel figure is published.
NapLab measurementPosition × body weight
Who should—and should not—choose it
These calls follow NapLab's position-by-weight ratings for the Renew, which use the same three bands. NapLab does not score combination sleeping, so that row is our reading of its other results.
Side
Under 150 lb
Not recommended
NapLab rates this band “no” in every position. With slight contour and a light body, the shoulder has little to sink into.
150–250 lb
Not recommended
NapLab’s “no”: hip pressure topped 2.0 PSI on several side maps. Purple’s listing names side sleepers as a fit; the measurements do not back that up.
250–300 lb
Not recommended
Still a “no” from NapLab. More weight loads the hip harder on a 6/10 surface with no zoning.
Back
Under 150 lb
Not recommended
NapLab rates back sleeping “no” below 150 lb; a light body floats on the grid and gets little lumbar contact.
150–250 lb
Possible fit
NapLab’s “maybe” and the band it names as the best fit. Low sinkage keeps the hips level.
250–300 lb
Possible fit
A NapLab “maybe”. The foam core has no coils, so watch for edge collapse and earlier softening under higher load.
Stomach
Under 150 lb
Not recommended
NapLab rates this band “no” across positions, including stomach.
150–250 lb
Possible fit
NapLab’s “maybe”. Only 1.98 in of sinkage helps keep the midsection from dipping.
250–300 lb
Possible fit
NapLab’s “maybe”, with the same foam-core caveat as back sleeping at this weight.
Combination
Under 150 lb
Not recommended
NapLab does not score combination sleeping separately; with every position rated “no” in this band, we do not recommend it.
150–250 lb
Use caution
The 0.3 s recovery makes turning easy, but time spent on the side meets the bed’s worst result. Mostly-back combination sleepers fare best.
250–300 lb
Use caution
Easy to move on, but side time is still a poor fit and the edge compresses deeply when you sit to get up.
Fit calls are qualitative editorial interpretations of published lab results. They are comfort and alignment judgements, not clinical recommendations.
Inside the 11 inches
Two inches of grid, nine inches of foam
Purple publishes every layer thickness. It does not publish foam densities, and NapLab lists them as not available. NapLab records the law-tag materials as 56% polyurethane foam pad, 43% gel pad, and 1% polyester fibre.
| Layer | Thickness (in) | Role |
|---|---|---|
| SoftStretch cover | — | Polyester/spandex top panel. The Costco-exclusive two-tone version is the only published difference from the PurplePlus. |
| GelFlex Grid | 2 | Hyper-elastic polymer in an open grid. Its columns buckle under heavier points and leave channels for air. |
| Polyurethane comfort foam | 2 | NapLab’s reviewer found this layer unremarkable in quality and feel. |
| Polyurethane comfort foam | 3 | Transition foam between the grid section and the base. |
| Polyurethane base foam | 4 | The support core, with a foam edge perimeter. No coils anywhere in the build. |
That layout explains both ends of the measurements. The grid sits right under the cover, so heat escapes quickly and the surface springs back in a third of a second. With no coils, edge support depends on a foam perimeter, and NapLab watched the grid fold in on itself when it sat at the side.
Claims versus evidence
Purple names side sleepers; the lab does not
What Purple says
The purple.com listing calls the Renew best for back, side and combination sleepers, describes a medium feel with shoulder and hip pressure relief, and says the feel helps reduce pressure buildup and pain. Costco’s listing repeats that the grid relieves pressure. These are the manufacturer’s and retailer’s descriptions, not test results.
What the evidence shows
NapLab measured the bed firmer than the label, at 6 of 10, recorded readings above 2.0 PSI at the hips on several side-sleeping maps, and rated side sleeping “no” in all three weight bands. Its reviewer concluded the main reason to choose the Renew is a strong preference for the grid itself. NIAMS notes that back pain has many causes; a mattress’s comfort is not treatment for any of them.
This review is general product information, not medical advice. A mattress does not diagnose, treat, or cure any medical condition. If you have persistent or severe pain, talk to a qualified healthcare professional.
Useful comparisons
Telling the Renew apart from the rest of Purple
Renew vs PurplePlus
Purple says the build is identical and only the cover differs, so the decision is the purchase channel, not the feel. Choose the Renew for the Costco price, delivery and returns; choose the PurplePlus if you want Purple’s own trial, a California King, or a non-Costco checkout.
Renew vs the original Purple Mattress
The same 2 in grid on a thinner base: the original is 9.25 in tall against 11 in, and also measured 6 of 10 elsewhere on this site. It listed at $1,599 for a queen on purple.com at our October check. The Renew adds foam depth under the grid and is cheaper at Costco; the original is the lower-profile option.
Renew vs Restore Hybrid
The Restore puts the grid over pocketed coils at 11.5 in and listed at $2,699 for a queen in September. Coils are the usual answer to the Renew’s weakest result, its soft seated edge, but no lab has measured the current Restore feel, so that remains an expectation rather than a finding.
Renew vs Casper Cooling Select Hybrid
The other Costco-exclusive bed on this site, at $749.99 list for a queen in October. NapLab measured it at 6.39 m/s² of motion and 3.50 in of seated edge compression, both better than the Renew’s 8.26 and 5.50. Pick the Casper for edges and price, the Renew only if you want the grid.
Returns and warranty mechanics
Whose policy you get depends on the checkout
At Costco there is no named sleep trial. The satisfaction guarantee covers the purchase, Costco.com orders can go back to any warehouse, and the published policy sets time limits only for electronics and a few other categories. On purple.com the Renew has a 100-night trial, but you must sleep on it for 21 nights first, send photos with the law tag attached, and accept a refund that can be reduced by discounts and transportation costs. NapLab says Purple’s customer service quoted it a $150 return fee.
Wherever you buy, the warranty is Purple’s: ten years from purchase, for the original purchaser, with a visible impression deeper than 1.0 in counting as a defect. For a Costco purchase Purple sends you to Costco first. Purple requires a frame with centre support and five or six legs for a queen or larger, and slats no more than 3.5 in apart, and may ask for proof of the foundation before honouring a claim.
Living Review durability outlook — qualitative, not observed
What to watch over the years, and why we cannot model it
Assumptions: one or two adults within NapLab’s 150–250 lb fit band, nightly use, a foundation that meets Purple’s requirements, and regular rotation. Inputs are Purple’s published thicknesses and NapLab’s measurements of a new unit. No foam density, ILD, or long-term test of the Renew is published, so we give no forecast curve, probability, or score.
Most likely first change
The edge. It already compressed 5.50 in when new, and a foam perimeter carries every sit-down. After that, the polyurethane under the hips, since the whole support core is foam with unpublished density rather than coils.
What works in its favour
The grid is a polymer, not a foam, and is the layer that sets the feel. Purple’s 1.0 in indentation threshold is stricter than the 1.5 in some brands use, and a Costco purchase adds Costco’s return policy on top.
Uncertainty and update rule
Confidence is low on timing. We will revise this section if Purple publishes densities or changes the layer list, if a lab tests the Renew or PurplePlus over time, or if consistent owner reports tie a specific change to a specific age.
Frequently Asked Questions
Is the Purple Renew the same as the PurplePlus?
Purple says so. Its Renew listing states that the only difference between the PurplePlus and the PurpleRenew is a Costco-exclusive two-tone cover, and both list a 2 in GelFlex Grid over foam at 11 in. Purple publishes the Renew’s layers as 2 in grid, 2 in and 3 in comfort foams, and a 4 in base. Sleep Unpacked has not independently confirmed the two builds are identical.
Where can you buy the Purple Renew?
Mainly at Costco. Purple moved the Renew into Costco warehouses nationally in December 2025 and onto Costco.com from 26 December, according to trade press. On 7 November 2026 Costco.com sold the queen for $1,299.99 and the king for $1,599.99, delivered and set up. purple.com also lists it, at $1,899 for a queen, plus a California King size Costco does not list online.
How firm is the Purple Renew?
NapLab measured 6 out of 10, which it calls medium-firm, even though Costco and Purple label it medium. Sinkage was shallow at 1.98 in, so you sleep on top of the grid rather than in it.
Is the Purple Renew good for side sleepers?
Not according to the only independent test. Purple’s listing names side sleepers as a fit, but NapLab recorded hip pressure above 2.0 PSI on several side-sleeping maps and rates side sleeping “no” at every weight it scores. Back and stomach sleepers from about 150 to 250 lb get a “maybe”.
What is the return policy on a Purple Renew from Costco?
Costco’s, not Purple’s. Costco.com orders can be returned to any warehouse under its satisfaction guarantee, and its published policy names no time limit for mattresses. Purple’s 100-night trial with a 21-night minimum applies to purple.com purchases.
Does the Purple Renew have springs?
No. Under the 2 in grid are 9 in of polyurethane foam in three layers, with a foam edge perimeter. Purple’s coil beds are the Restore Hybrid line.
What does the Purple Renew warranty cover?
Ten years, for the original purchaser. Purple treats a visible indentation deeper than 1.0 in as a defect, a stricter line in the owner’s favour than the 1.5 in some brands use. For a Costco purchase, Purple asks you to start the claim with Costco and keep the receipt and the law tags.
