About the Manufacturer

Kolcraft started in Chicago in 1946 when Leo Koltun made playpen pads out of cotton batting and oilcloth covers for post World War II babies. In 1949, he found himself with surplus padding and used his ingenuity to invent the all-around crib and playard bumper pad.

A period of rapid growth followed as the company expanded into manufacturing other types of pads including Crib Mattresses in 1951. Since that time, Kolcraft has become America's #1 Crib Mattress manufacturer. In 1979, Kolcraft began making plastic products with the introduction of the innovative Carri-Cradle; the first combination plastic infant carrier and rocker with a carrying handle. Kolcraft continued its expansion into the manufacture and distribution of other product categories including: playards, high chairs, walkers and strollers. By 1994, Kolcraft became one of the nation's leading suppliers of strollers.

In the late 1990's, Kolcraft continued to grow by entering into additional new categories with quality, innovative children's products. These new areas included bassinets, bouncers, swings and juvenile furniture.

Kolcraft continues to be the #1 Crib Mattress manufacturer and is now the market leader in bassinets. In addition to the Kolcraft Brand, they are now also partnered with recognizable brand names such as Sealy®, Sesame Beginnings™ and Jeep®, leaders in their industries, to produce a variety of children's products.

As Kolcraft continues into the new millennium, it also continues its commitment to quality, value and service. Kolcraft's continuity of family ownership sets them apart--it allows them to have an entrepreneurial approach and be able to provide the right merchandise, at the right price, at the right time.

Best Mattress Bar-Non

Augustine from Bronx, NY– Verified Buyer

My daughter loves this mattress. She can sleep for several hours even turning over in her sleep she does not wake up. And when she wakes up's see wakes up with a big smile. The mattress is comfortable yet firm enough and she does not sink in whether she's laying down or up on her hands looking about. It has no offending smell right out-of-the-box whatsoever and is very quiet. I would recommend this mattress to anyone with all of its wonderful features is the perfect mattress for our baby and yours.

Great value and quality

Donna from Texas– Verified Buyer

The mattress arrived very quickly and exceeded our expectations. It is very comfortable for the baby and is watrproof and is easy to clean. Great value and more affordable with the same benefits as higher end crib mattresses.

Great product!

Raven from Lexington, KY– Verified Buyer

I was looking for a mattress that had great quality and was comfortable for a reasonable price. I got exactly what I was looking for and wanted. I haven't been able to put it with my sons toddler bed because I am in the process of moving, but I was able to take it out of the package and test it out. It's not plasticity nor hard either !

Great Buy

Laurie from Clay, MI– Verified Buyer

Arrived in perfect condition and fast - as usual. Great value and should last for several years to come. Saved $$$ versus shopping at a major "baby" store. Thank you for offering the public such great deals.

Nice mattress for the money!

Tahnee from Orlando, FL– Verified Buyer

I bought this mattress myself based on the previous reviews and I feel I made the right decision. This will be used on a toddler bed (which I also bought on here) and it is very nice. It is probably nicer than the one I bought to go with the crib a few years ago. Good quality mattress for the price. Fast delivery with no problems.

lacy from Paoli, OK– Verified Buyer

I bought this mattress because it was on sale and had decent ratings. I would have to agree with most posts. It does its job as a mattress but doesn't have some of the support others have. I had to buy a second crib & mattress since my kiddos are 13 mos apart. So in comparison to the first one I have, which is foam supported, this one is very springy and my little one slightly sinks into it. Not ideal, but no real danger and I'm not losing sleep over it.

Awaiting tester...

Phillip from Pembroke Pines, FL– Verified Buyer

My wife and I did some research on mattresses, and this seemed to be a great deal on a top rated mattress... we're still waiting on our little one to be born, but I'm sure he'll like it.

Nice Mattress

Helen from Bartlett, TN– Verified Buyer

I didn't want to spend a bunch of money on a mattress and this seemed like a good deal. I couldn't be happier. The mattress is firm enough and fit right into the crib easily. It was a really good buy.

Tricia from The Colony, TX– Verified Buyer

I bought this for my 7 month old baby after doing some research for a few days. I love the quality of this mattress once I received it and my baby sleeps very soundly on it. I also love how the mattress is waterproof. I am very pleased with my purchase.
