Plank Firm Luxe Review: Is It Right for You?

Pick Firm for the less-firm side and Extra Firm if you want a harder feel. Brooklyn Bedding rates Firm at 7.5-8 out of 10 and Extra Firm at 9.5-10 out of 10, so its numbers put Extra Firm higher.

Outside readings also put Extra Firm above Firm: Sleep Foundation rated the Firm side Firm (7) and the Extra Firm side Extra Firm (9). Mattress Clarity scored Firm Side 7.5/10 and Extra-Firm Side 8/10; Sleepopolis scored Firm side 7/10 and Extra-firm side 7.5/10. GoodBed rated the mattress Very Firm (2) on its rating scale. Choose by how firm you want the bed to feel.

The Plank Firm Luxe may suit sleepers over 230 pounds, especially stomach sleepers; Sleep Foundation’s position ratings top out at 9.0. Choose a side based on your position and weight, since preferences differ.

• Side sleepers over 230 pounds: Sleep Foundation rates fit 8.5, a favorable signal for that group.
• Back sleepers over 230 pounds received a rating of 8.5 and tended to prefer the extra firm side. Those under 230 pounds tended to prefer the firm side.
• Stomach sleepers over 230 pounds received a 9.0 rating, and the extra firm side was most popular. The firm side was preferred by those under 230 pounds.

Brooklyn Bedding says its mattresses are designed to support up to 950 pounds. Sleep Foundation gives edge support an 8.5/10 score, a favorable sign if you sit or sleep near the edge.

The Plank Firm Luxe may suit back-pain shoppers seeking firm support, but no pain relief is assured. Brooklyn Bedding says its three month study found the design reduces spinal stress, improves lumbar support, and alleviates back pain.

Tom's Guide's reviewer says it keeps the body lifted and aligned; back-sleeping testers liked its stable, full-body support. For back support, the firm side is the clearest starting point: Sleep Foundation's most favorable sleeper-fit ratings came from back and stomach sleepers weighing at least 130 pounds, and most testers preferred it. A few testers weighing more than 230 pounds appreciated the extra firm surface's light contouring and robust support.

The outside readings show warming, not a neutral temperature result. Brooklyn Bedding says the breathable quilted top, open-cell foam, and individually encased coils support airflow. The optional GlacioTex™ Cooling Cover is another cooling part. Sleepopolis recorded an 11.7-degree increase on the extra-firm side and a 9.7-degree increase on the firm side after five minutes. NapLab recorded a baseline of 76.6° F, a max of 86.9° F, and an ending reading of 78.4° F. Expect some heat buildup in these tests, despite the airflow-focused build.

Sleepopolis's readings suggest a light sleeper may feel less partner movement on the firm side. It recorded motion isolation at 5/5 on the firm side and 4.7/5 on the extra-firm side, so start with firm if a restless partner wakes you. Sleepopolis also recorded 30 inches of bounce on both sides, which points to a lively rebound. That bounce reading does not say how much movement reaches your side, so do not treat the isolation score as a promise of stillness.

At the Queen list price of $1,598, read on 2026-10-18, it is worth considering if the cost fits your budget and your frame is 60 x 80 inches.

Plank Firm Luxe list prices by size

Height: 13 inches

The Plank Firm Luxe uses a foam-and-coil stack running from its Extra Firm Side to its Firm Side.

• Optional GlacioTex™ Cooling Cover (Extra Firm Side)
• Quilted top, 0.75 inches
• High-density support foam, 2 inches
• Individually encased Ascension Firm coils, 6 inches
• High-density support foam, 2 inches
• Supreme Response Comfort Foam, 1 inch
• Quilted bottom, 1.5 inches
• Optional GlacioTex™ Cooling Cover (Firm Side)

Brooklyn Bedding says it is made in America using foreign and domestic components, so its stated origin does not mean every component is domestic.

Also in the build: .75” Quilted Top, 1.5” Quilted Bottom. The sources we read name these layers but not what they are made of.

Brooklyn Bedding says the Plank Firm Luxe has a breathable quilted top on both sides, with open-cell technology throughout its foam layers. The two certifications cover different parts: CertiPUR-US applies to the foams, while GREENGUARD Gold applies to the mattress. That distinction helps you check whether a label covers the foam or the mattress itself.

Brooklyn Bedding says its mattresses are 100% fiberglass free. To check the Plank Firm Luxe's fire barrier material, read the law tag, which lists the mattress materials. Use the tag's wording to decide whether the listed materials suit your needs, rather than treating the brand's fiberglass-free statement as a detailed account of the barrier.

Tom’s Guide predicts a 6 to 10 year lifespan for the Plank Firm Luxe. Brooklyn Bedding says its Plank mattresses can be flipped to customize the sleep surface; its general guidance says most of its mattresses should be rotated every 6 to 8 months and not flipped.

Allow 30 to 45 nights for the mattress to break in, then the same amount of time for your body to adjust. Give yourself that time before deciding whether its feel works for you.

Brooklyn Bedding says the Plank Firm Luxe arrives compressed in a box by FedEx Ground to your door; you must set it up, and old mattress removal is not offered. Product pages say it ships in 5 to 8 business days, then takes about 2 to 5 business days by FedEx. California deliveries get free haul away.

The brand says the Plank Firm Luxe trial lasts 365 nights, with No fee for a return. That gives you time to decide whether to keep the mattress without paying a return charge. Use the trial to judge whether the bed suits you.

The Plank Firm Luxe warranty sets a covered-sag threshold of 1.5 in and lets Brooklyn Bedding choose repair or replacement. Years 1 to 10 are covered at no cost; later years are prorated. Keep the cover on: removing it voids coverage. Burns, cuts, stains, liquid damage, and beds from unauthorized sellers are excluded.

Owners praise the Plank Firm Luxe’s comfort and firm support, but some say it is not firm enough. Brooklyn Bedding’s site gives it a 4.5638037 / 5 rating from 3,260 reviews, reflecting feedback from the brand’s own customers.

Brooklyn Bedding lists Sleep Quality at 14%, Mattress Firmness at 11%, and Mattress Support at 7%; owner comments on its site praise comfort, the two firmness options, and support. Tom’s Guide also reports owner praise for firm support and back-pain relief. For the trade-off, Brooklyn Bedding displays an owner complaint that the bed is not firm enough, and Tom’s Guide says some owners found it less firm than expected. If you need a very firm feel, that mismatch is a real fit risk.

Brooklyn Bedding’s siblings are the first alternatives to weigh; choose based on the feature you want. Brooklyn Bedding offers Signature Hybrid in soft, medium, and firm feels. The brand describes Aurora Luxe Cooling’s foam as helping maintain sleep temperature, positions CopperFlex around affordability, calls Plank Firm an all-foam mattress, and presents ThermoBalance as featuring triple-cooling technology. Brooklyn Bedding says Sedona’s microcoil layer adds responsive contouring support and airflow. The brand says Spartan’s cover uses Far Infrared Rays for muscle recovery and describes BB Kids as its kids mattress. Titan Plus Luxe is for plus-size side sleepers; Titan Plus Elite is for plus-size sleepers who want dual coils.

Consider Saatva HD if you weigh 300 to 500 pounds: Sleep Foundation gives it a 9.2/10 overall test lab score. Its Queen price is $3,639. Choose Siena 10” Signature Memory Foam Mattress for a kids’ or guest-room bed. A Queen costs $329. Sleep Foundation calls it affordable and gives it a 7.5/10 score, but says it lacks support for most stomach sleepers, so that group should look elsewhere.

The Plank Firm Luxe launched in 2021. If you are making a shortlist, record this as the model’s launch year. That gives you a consistent date label to use while sorting your mattress notes and comparing launch timing across the models you are considering.
