Brooklyn Bedding Plank Firm Mattress Review

How Did the Brooklyn Bedding Plank Firm Mattress Perform?

Based on user reviews and trusted review sites.

Mattress Performance Score:

6/10

1. Comfort Layers & Support (Score: 5/10)

The thin quilted polyfoam tops provide minimal cushioning over a dense foam core. Heavier users praise the unyielding base for preventing sinkage. The Plank Firm mattress is less about comfort than it is proper alignment and support. Unfortunately, recent reports of body impressions forming in the first year raise a red flag, indicating that said support may be reduced sooner rather than later.

2. Firmness & Pressure Relief (Score: 4/10)

Most experience the ultra-firm side as board-like (fitting), while the medium-firm side adds minor contouring for those who need to take the edge off of this serious bed. Pressure mapping shows high buildup at the hips and shoulders. Lighter sleepers often find it unforgiving, leading to more pain instead of less.

3. Sleeping Position Compatibility (Score: 5/10)

Back and stomach sleepers over 230 lbs benefit the most from the Plank firm, designed for hip elevation and spinal alignment. Side sleepers should avoid this mattress altogether, or they may experience intense joint pressure. Combination sleepers note easy movement but inconsistent comfort when flipping sides.

4. Edge Support (Score: 8/10)

Dense foams create sturdy perimeters with little collapse when sitting or lying near edges. Couples maximize surface area without rolling off. Heavier users confirm reliability during entry/exit. This aspect is even stronger when upgrading to the Plank Firm Luxe, a hybrid model featuring a core of wrapped coils.

5. Cooling (Score: 6/10)

Open-cell foams promote airflow for neutral sleeping. Hot sleepers report retention without the GlacioTex top layer upgrade, which improves dissipation but adds cost. Those who overheat may want to look elsewhere or opt for the hybrid model as well as the GlacioTex to experience greater airflow.

6. Eco-Friendly & Off-Gassing (Score: 7/10)

CertiPUR-US certified foams lack harmful chemicals, but they meet only a bare minimum industry standard. Initial odor dissipates in days for most, but some users have complained that Plank mattresses take some extra ventilation to air out satisfactorily. Other reviews suggest that other Plank products, particularly their pillows and toppers, carry an unpleasant lingering odor.

7. Motion Transfer / Motion Isolation (Score: 8/10)

All-foam design absorbs movement effectively, making this a good bed to share. Partners rarely disturb each other during tossing. However, it’s an average bed for sex, since all-foam isn’t as easy to move around on when you’re “getting busy.” Light sleepers with active co-sleepers highlight this strength.

8. Warranty (Score: 5.5/10)

“Limited lifetime” is a misleading term; 10-year coverage handles defects but requires 1.5-inch impressions for sagging claims. Users report denials for minor issues or lack of protector. Prorated replacements increase costs over time.

9. Sleep Trial (Score: 7/10)

120 nights is a fair industry standard, especially with a free topper option for firmness tweaks. Some have been surprised by a $99 return fee, something not explicitly stated in Plank’s terms. Some praise the flexibility, others note hassle with pickup.

10. Customer & Trusted Ratings (Score: 4/10)

Review averages hover in the mid-range, but user forums and 1-star reviews reveal polarization in the Plank owning community. Positive notes on initial firmness contrast quality decline complaints, with some wishing the warranty was more forgiving. Brand loyalists have even questioned whether the quality of Plank’s products has declined in recent years, reporting that their newer Plank beds fail sooner than their older units. While there’s plenty of positive feedback from happy back sleepers, the negative reviews are certainly concerning.

A Closer Look at the Brooklyn Bedding Plank Firm Mattress Materials

The Plank is a 10.5-inch flippable all-foam mattress that emphasizes density for maximal support and spinal alignment.

Here’s a breakdown of each layer:

Ultra-Firm Side Quilted Polyfoam (0.75 inches)

Thin quilting minimizes sinkage for a flat, board-like surface using breathable fibers.

TitanFlex Foam Transition (2 inches on medium-firm side only)

Responsive polyfoam adds bounce and minor contouring, absent on ultra-firm for pure rigidity.

High-Density Support Core (7-8 inches)

Thick base foam delivers durability and prevents bottoming out, ideal for heavier weights.

Medium-Firm Side Quilted Polyfoam (1.5 inches)

Extra loft provides a subtle cushion while maintaining support.

The Brooklyn Bedding Plank Firm Luxe

If the Brooklyn Bedding Plank Firm sounds too serious, consider opting to upgrade to the Plank Firm Luxe Mattress, a 13.25-inch hybrid model that replaces the dense foam core with individually wrapped coils encased in high-density foam. This adds significant bounce, deeper compression support, and dramatically improved airflow compared to the all-foam version, while preserving the same flippable ultra-firm and firm feels with thicker quilted panels for a more luxurious surface. The Luxe also integrates stronger edge reinforcement and an optional GlacioTex cooling cover that performs better due to the coil layer’s natural ventilation.

Heavier sleepers (250+ lbs), hot sleepers, and anyone who found the original Plank too “dead” or prone to heat buildup will appreciate the Luxe most. Back and stomach sleepers get the same rigid spinal alignment, but with responsive pushback that makes position changes easier, and the hybrid design reduces the sagging complaints that plague the foam-only model. It’s a much friendlier model for “amorously active” couples, who also benefit from superior motion isolation despite the coils, and the taller profile pairs better with deeper sheets and modern bed frames.

Our Analysis

Brooklyn Bedding launched in 1995 as a factory-direct operation in Phoenix, Arizona, cutting out middlemen to deliver lower prices than big-box retailers. The company built early credibility through chiropractic partnerships, positioning the Plank as a therapeutic tool for chronic back pain sufferers who need unyielding support.

However, a 2023 class-action lawsuit filed by plaintiff Sean Phillips in the U.S. District Court for the Northern District of California accuses Brooklyn Bedding of deceptive pricing on Leesa brand products, alleging inflated regular prices and fake limited-time sales with countdown clocks that never end. The suit claims these tactics mislead consumers into believing discounts are greater than they are, violating false advertising laws and seeking damages for affected buyers. With Plank falling under the Brooklyn Bedding umbrella, it’s easy to wonder if this practice stretches across their product lines.

Warranty enforcement remains the biggest reputational sore spot—multiple verified owners report claims rejected because impressions measured 1.25 inches instead of the required 1.5 inches, leaving buyers stuck with sagging beds and no recourse. Despite these issues, the brand still earns praise for transparency about foam density and for manufacturing everything under one roof.

Customer Insights

Feedback on the Plank Firm Mattress varies greatly. Older reviews express satisfaction, praising the Plank for relieving back pain. On the official PlankMattress site, 2024–2025 reviews repeatedly ask whether Brooklyn Bedding changed foam suppliers, with long-term owners claiming pre-2022 models stayed rock-hard for 5+ years while newer units soften or sag within six months.

Forum threads show a clear weight divide: users over 250 lbs often call it “the only mattress that keeps my spine straight,” while those under 180 lbs describe the ultra-firm side as “sleeping on plywood” and the medium-firm side as “deceptively soft after two months.” Some users with smaller body types still report early breakdown in the mattress, indicating that weight isn’t necessarily what leads to the issue.

Final Verdict: 2/5 [Editor’s Rating]

True to Its Name: A Plank Fit For Floor Sleepers

The Brooklyn Bedding Plank Firm mattress remains one of the least expensive ways to get true ultra-firm support without coils, making it tempting for heavier back and stomach sleepers who have struggled with softer beds causing hip sinkage or lower-back pain. If you weigh 230–300+ lbs and strictly sleep on your back or stomach, the initial feel and spinal alignment can feel life-changing for the first year, especially at sale prices.

Everyone else—side sleepers, combination sleepers, lighter individuals, or anyone planning to keep a mattress longer than three years—should steer clear due to widespread sagging reports and unforgiving pressure points. Couples with different body weights face an additional gamble, as one partner often loves the firmness while the other wakes up sore, defeating the flippable design’s promise.

Ultimately, the Plank delivers exactly what it advertises for a narrow audience but fails spectacularly for the majority, turning a budget win into an expensive mistake when early replacement becomes inevitable. If you’re still determined to try a Plank mattress, we’d recommend skipping straight to the hybrid Luxe model–the upgrade could save you the disappointment from its entry level all-foam version.
