Sealy Crib Mattresses Reviewed: Ortho, Premier, Signature, And More

The arrival of a newborn is always a happy event for any family, but apart from the gift showering, the most important element in the baby’s new room should always be their sleeping place. A good quality crib mattress will not only offer many nights of proper rest, but it will reduce the risk of SIDS (Sudden Infant Death Syndrome). 

Breathability, organic materials, and an open-cell foam construction in a baby crib mattress are key elements for SIDS prevention, given the fact most babies are stomach sleepers and some of them will even love to sleep with their face down on the pillow. Plus, leaking accidents happen and a crib mattress should also have impermeable qualities or should be easy to clean/wash to offer freshness and dryness throughout days and nights.

When it comes to sleeping products brands, we must highlight Sealy as a veteran brand expert in manufacturing quality products for the entire family.

Sealy Brand Overview

Sealy is a worldwide known brand that surprisingly, had a very humble beginning. Everything started in the small town of Sealy, in Texas, when Daniel Haynes, a cotton gin builder was commissioned to make a bespoke cotton-filled mattress.

The product that Daniel delivered back in 1881 was praised by its buyer and people from his neighborhood. Motivated by the positive response to his crafted mattress, Daniel developed a machine that would compress cotton to make it easier to build mattresses with. The innovative, clever man got a patent for his invention in 1889, he became the first Sealy CEO and the rest is history.

Who hasn’t heard of this brand or hasn’t owned a Sealy mattress? Nowadays, this conglomerate has extended further the US to countries like Korea, Canada, México, Singapore, among others.

But let’s talk about Sealy’s products in the kid’s department. We have put together a useful mini-guide for you to know more about their children’s sleeping products.

Sealy Crib & Toddler Mattresses Buying Guide

The Sealy Baby line that produces a wide array of bedding products for children earned the “Healthiest Crib Mattress” title in the 2020 Cribsie Awards, plus the brand holds a good number of important quality certifications; Certi-PUR US, Greenguard Gold included. 

But, let’s quickly review the highlights of the brands that make Sealy Baby a parents’ favorite:

Organic & Hypoallergenic:

Sealy is always on the lookout for new organic materials to add to their baby products. Most Sealy crib mattresses come with added cotton either on the covers or in the interior layers for more organic breathability. Also, Soybean treated foams are the latest addition to their dual-use (baby and toddler) mattresses. And even though some models still use regular comfort/memory foam for the interior plush layers, Sealy developers always find alternatives to make their baby products breathable and hypoallergenic. This reduces the risk of suffocation and provides your child with a pleasant sleeping experience without allergies or respiratory problems.

Impermeability and Standard Size:

Sealy mattresses either come with waterproof covers or they may include a water repellent lining underneath the top cover (stitched or removable) that prevents liquids from seeping inside the foam layers or the innerspring. This can damage the mattress by storing odors and stains that would be almost impossible to remove afterward. Also, most Sealy baby crib and toddler mattresses are made to fit almost all standard-sized US cribs and toddler beds (52 x 28 inches). 

Often, they come with reinforced square edges for a snug fit. However, if a Sealy mattress does not fit your crib properly and you detect dangerous gaps between the mattress and the frame, you may want to ask for a refund on the product or readjust your crib (if possible).

Flame retardants & Low on VOC emissions: 

Every Sealy crib mattress is Greenguard GOLD certified, and CPSIA tested, which means, such products are free from lead, mercury, and other heavy metals. They don’t contain phthalates or fire retardants such as fiberglass interior layers. Up to this day, it is still a tricky topic to talk about fiberglass barriers in baby mattresses and sleeping products in general as some bedding product companies still refuse to ditch the material as a flame retardant in their products. 

Sealy baby products also successfully pass ASTM and CHCH standards (Chemicals of High Concern to Children), and they have been tested as low in VOC emissions. Nevertheless, it is a good idea to air a new baby crib mattress for at least 48 hours before use.

Price, Warranty, and Delivery:

Sealy Baby products are affordable and they have been rated as durable by many happy parents. The prices of a standard crib mattress by Sealy may fluctuate between 88 and 200 dollars. 

The brand offers a limited lifetime warranty (or 7 years full warranty) on their baby products. When it comes to delivery options, the Amazon Sealy store may have some shipping offers such as Amazon Prime available for you, or you may want to check out Sealy Baby’s official website, as delivery may be free for purchases over 49 dollars. Not bad, huh?
