Plank

The Plank and Plank Luxe Hybrid are both exceptionally firm mattresses; it’s what they were designed to be. However, the Luxe Hybrid is noticeably softer than the all-foam Plank.

On the firmness scale, with 1 being very soft and 10 being very firm, our ratings are:

• 8 for the Plank’s firm side and 9 for its extra-firm side.
• 7.5 for the Plank Luxe Hybrid’s firm side and 8.5 for its extra-firm side

Since these mattresses are so firm, they aren’t great for side-sleepers as they won’t provide pressure relief for your hips and shoulders. But for back and front sleepers looking for a firm mattress, the Plank varieties are a dream come true, and even are double sided with one side that’s less firm (but still firm).

Plank offers an additional cooling topper, however it’s not included in the price of the mattress.  Otherwise the mattress is pretty standard in terms of temperature regulation and cooling properties. If you decide to invest in the cooling topper, it’s described as a ‘PCM surface infusion of TitanCool’ and is a great option for hot sleepers, scoring a 2/10, with 1 being the coldest.

For side sleepers, the Plank mattresses won’t really provide the pressure relief that you’ll need when sleeping – a softer mattress would be better. But for back and side sleepers the Plank mattress provides slightly more pressure relief, especially in the lumbar region.

It’s easy and comfortable to move around on the Plank mattresses, making them a good option for combination sleepers and those that toss and turn throughout the night. The material used in the mattresses, the TitanFlex is similar to latex in that it contours to the sleepers body.

With the Plank mattress, you’re likely to feel your partner moving around if you share the bed due to the high motion transfer it is. I’d say this mattress is better for someone who doesn’t share the bed with a partner or pet, or isn’t the lightest sleeper. This doesn’t mean this isn’t a great mattress brand, but due to its higher than usual level of firmness, it’s not ideal for motion isolation.

The edges of the Plank mattresses are not reinforced, meaning that the edge support is not great. The extra firmness of the mattress however might still contribute to a more ‘secure’ feeling when laying down on the mattress, with only a slight feeling of ‘sinkage’ when sitting right near the perimeter of the mattress.

The Plank and Plank Luxe Hybrid share similar materials, but their construction is quite different. Here’s a quick breakdown of their construction from top to bottom.

The Plank [Extra-firm side from top to bottom]

Quilted Top Layer

The extra-firm side has a 0.75-inch flat, quilted top layer, offering extra-firm support.

Base Layer

This seven-inch high-density foam layer forms the body and gives your mattress the durability needed to last for years.

Comfort Layer

This two-inch comfort layer is made from Plank’s trademarked high-density polyfoam, TitanFlex.

Quilted Bottom Layer

The quilted bottom layer has the same material as the top layer, but the former is 1.5-inches thick. And if you flip the mattress, this side becomes the firm side’s top layer.

The Plank Luxe Hybrid

The Plank Luxe Hybrid’s construction is similar to the Plank’s, with two important distinctions:

• The hybrid has a six-inch middle layer of individually wrapped TitanCaliber coils.
• The hybrid has two high-density foam layers, each two inches thick, surrounding the innerspring layer.

The Plank Luxe Hybrid’s extra-firm side’s construction, from top to bottom, is:

• 0.75-inch quilted top layer
• 2-inch high-density support foam
• 6-inch TitanCaliber coils layer
• 2-inch high-density support foam
• 1-inch TitanFlex comfort foam
• 1.5-inch quilted bottom

And just as with the Plank, you can flip the Plank Luxe Hybrid over to get the firm side.

Both models have a breathable quilted top cover with continuous stitching. The cover is non-removable, so you’ll need to spot-clean any stains or spills.

Alternatively, if you prefer a cooler mattress, you can buy Plank’s cooling cover – which Plank describes as “A PCM surface infusion of TitanCool.”

You can purchase Plank’s mattresses and accessories directly from their website, or alternatively from Amazon. The sleep brand offers free shipping in the U.S., with the exceptions of Hawaii and Alaska – the shipping fees to these locations starts at $125/mattress.

Plank also ships their mattresses to Canada via FedEx International Shipping, but the shipping fees are hefty – starting at $250 for a single mattress. Each Plank mattress comes with a 120-nights trial and a 10-year warranty.

However, if you want to return your bed within the trial period, the brand requests that you try the mattress out for at least 30-days.

Plank offers financing options, which you can avail at checkout. They also offer regular discounts to military personnel, first responders, educators, students, and medical providers.
