Plank Firm Luxe Mattress Review: Benefits and Any Drawbacks
Our team has researched and reviewed the Plank Firm Luxe mattress. In the following sections, we share our opinion of its benefits and any drawbacks.
Choose Your Firmness Level
The Plank Firm Luxe mattress is practically two mattresses in one, with a firm feel on one side and extra firm on the other. High-density foam provides ample support on both sides. The firm side has an additional layer of Supreme Response comfort foam and slightly more lofting in the quoited cover. No matter which side you choose, you’ll have superior support from Brooklyn Bedding’s firmest foam.
Support Where You Need it Most
Speaking of support, the 6” coil core targets support where you need it most. We think you’ll like how the mattress offers extra support for your spine, shoulders and hips — especially while traveling for hours in an RV. If you tend to sleep in your stomach, this targeted support is especially beneficial because it prevents your midsection from sinking too low.
Comfort Without Sacrificing Support
On the firm side, the Supreme Response comfort foam relieves pressure while maintaining a firm feel. The foam conforms to your body and relieves pressure in your spine and joints, providing a slight cradling effect. Your hips, shoulders and spine stay aligned, thanks to this contouring yet responsive foam.
Temperature Regulation
The Plank Firm Luxe helps keep you cool during those hot summer RV trips. The open cell foam layers promote air flow that Carrie’s heat away from the mattress. The individually wrapped coils also allow air circulation. Plus, the optional GlacioTexTM cover feels cool on contact. Thanks to these advanced features, sleeping cool is no sweat.
Motion Isolation
We think couples will appreciate the motion isolation provided by the individually wrapped coils. The coils move with you and adjust to your position, prevent motion from transferring across the mattress surface. If you are a restless sleeper, your tossing and turn won’t disturb your spouse or partner. In our opinion, that’s a plus when it comes to sleeping in an RV.
High Profile and Limited RV Mattress Sizes
Before you buy an RV mattress, measure the RV sleep area carefully and check the weight capacity of the RV. At 13.25 thick, the Plank Firm Luxe mattress has a high profile that is suitable for larger RVs. Additionally, there are only two RV mattress sizes for this brand. Although the Plank form Luxe offers superior comfort features, you’ll want to make sure it’s a good fit for your RV.
Mattress In a Box
When you buy the Plank Firm Luxe mattress, you don’t have to wait around for a delivery team or transport the mattress to your home. That’s because Brooklyn Bedding compresses, rolls and packs the mattress in a box to ship directly to your door. You don’t even have to be home when it arrives.
After you unbox the mattress, you’ll have to wait 3 to 5 hours for it to expand. Before placing it in your RV, you may want to air it out for up to 24 hours to allow a harmless odor or “off-gassing” to dissipate.
120-Night Trial
When you buy the Plank Firm Luxe mattress, there’s no hurry to decide if it’s the right mattress for you. The 120-night sleep trial gives you four months to literally sleep on it — even in an RV.
A mattress has an initial break-in period of about a month. Brooklyn Bedding asks that you try the Plank Firm Deluxe for 30 days before making a final decision. If you decide not to keep the mattress within the 120-day trial, the company will arrange a pickup and refund. There is, however, a return fee to cover pickup costs. Whenever possible, the company will donate or recycle the returned mattress.

You can have peace of mind when you buy the Plank Firm Luxe, which comes with a lengthy limited lifetime warranty. Brooklyn Bedding will replace or repair a mattress that is found to have manufacturer defects, as decided by the manufacturer, based on policy details.
