Construction

The Slumber Cloud Dryline mattress protector is built from a blend of polyester (98%) and Lycra (2%). These two materials create a finish that is breathable with a nice softness to it. The cover also uses Outlast technology, which helps regulate the temperature. Compared to the thickness of the other protectors I have reviewed, this one is fairly thick.

What is Outlast? Outlast is a phase change technology that is incorporated into fabrics for the absorption, storage, and release of excessive heat. When used in bedding, it helps sleepers remain cool during the night and works to prevent body heat buildup.

The Dryline mattress protector is a 5-sided protector. The sides are thinner than the top cover and are made from a 100% polyester knit that still provides durability and softness. This protector has ultra-deep pockets to fit mattresses up to 16”. This protector itself is white with small dots about every 1/8” and the word OUTLAST printed in a diagonal pattern across the protector.

The Slumber Cloud Dryline mattress protector is available in Twin XL, Queen, and King. There is also a narrow piece of elastic that runs across the whole protector to provide a snug fit onto the mattress.

Invisibility & Protection

A good mattress protector has two main jobs: to protect the mattress and do so without being detected.

1. Protect the mattress: The first role is to protect the mattress. This includes protection from liquid spills, particles, dirt, dust mites, allergens, or anything else that may come in contact with the mattress.
2. Protect without being noticed: While it may be easy to protect a mattress from damage and stains, it is important that it does so without changing the feel of the mattress. A cool mattress should still be cool, it should retain the same amount of hug / contour, and overall it should feel the same with or without the protector.

Liquid Protector

Protection from liquid spills is one of the most important jobs of a mattress protector. Whether it be water, wine, or body fluids, when a liquid penetrates a mattress, it can be bad news. To test how a mattress protector performs when faced with liquid spills, I do a series of tests.

Test #1 – 2 minutes, 16 ounces of liquid

This first test is representative of a quick spill. This spill may be small or catastrophic, but it is detected early and there is time to clean it almost immediately. But is 2 minutes too long for a spill to soak? Will the Dryline mattress protector be able to protect the mattress?

• Spill Test – During this test, I dyed 16 ounces of water with food coloring for contrast and poured it directly onto the mattress protector. After 2 minutes had elapsed, I removed the mattress protector and ran it in a normal wash-dry cycle.
• After Wash Cycle – After the cycle had completed, this test concluded that the Dryline mattress protector was able to completely protect the mattress from the spill, and there were no stains or dye retention from the spill.

Test #2 – 8 hours, 16 ounces of liquid

This second test demonstrates a more challenging spill. This type of an accident is discreet and secretive. It goes unnoticed for hours, maybe even overnight. By the time it is noticed, the spill has had time to spread across a greater area of the mattress and fully soak the protector. Will the Dryline protector be able to persevere and save the mattress below?

• Spill Test – For this test, I dyed 16 ounces of water with food coloring for contrast and poured it directly onto the mattress. After 8 hours had elapsed, I removed the mattress protector and ran it on a normal wash-dry cycle.
• After Wash Cycle – After the cycle had completed, this test concluded that the Dryline mattress protector retained no evidence of stains, damage, or other forms of dye retention from the spill.

Allergens, Dust & Dirt

Detecting the presence of allergens, dust, and dirt particles can be very difficult to note without high-end equipment. The Slumber Cloud Dryline mattress protector does not claim that it protects against any allergens, so for sleepers who suffer from extreme allergies, I would not recommend this mattress protector. For everyday dirt and dust, the Dryline protector did a great job of limiting the presence of these irritants.

Noise & Cooling

Noise and cooling are two areas where this mattress protector really excelled. The Dryline mattress protector’s cover is made from a combination of polyester and Lycra, resulting in a soft and extremely quiet protector. Its added softness really makes this protector feel more like a thick fitted sheet than a waterproof protector.

As for cooling, this protector also did well. The cover’s integrated use of Outlast technology helps to dissipate heat away from you while you sleep and, although the protector didn’t feel cool to the touch, it did a nice job of preventing excess heat retention throughout the night.

Should you buy the Slumber Cloud Dryline mattress protector?

I would recommend the Slumber Cloud Dryline mattress protector to sleepers who:

• Want a soft feel – The combination of polyester and Lycra results in a protector that is soft to the touch, yet durable enough to effectively protect the mattress. Some protectors are slick to wick water away, but the Dryline protector is soft and has a way of absorbing the liquid into the center of the protector and holding it there, without allowing it to penetrate through the underside.
• Want a quieter protector – Again, the polyester and Lycra is a winning combination when looking for a quiet mattress protector. For heavier sleepers, this may not be an issue, but if you’re a lighter sleeper or have thinner sheets, this may be a larger factor for you.
• Want great cooling – The integration of the Outlast phase change material in the cover helps this protector to redistribute heat away from the body.
• Want a solid value – High-quality cooling mattress protectors are not cheap, but at $175 / Queen this protector is well worth that in its value and considerably expensive than competitive alternatives. Through all the tests, it protected the mattress and did so invisibly, while remaining virtually silent and undetected, and left the mattress cooler than it was without it.
