King Koil vs Sealy mattress review

If you would have asked somebody between the King Koil vs Sealy mattress 10 years ago, then the chances are that they would have suggested King Koil to you. Because 10 years ago King Koil was a lot more popular than it is now. Conversely, Sealy has made a comeback during the last 10 years. So today we’re going to check why exactly this is and what for most people would be the better option.

Here’s why you’d choose the King Koil mattress: good for your spine

King Koil works together with the national chiropractors association. This means that they have done their research on how their mattresses can be made optimally for your spine. So if you suffer from serious back problems, and your chiropractor has suggested that you buy a good mattress for this, then this might be the perfect option. Since chiropractors have been involved in the creation of the mattress, your spine will get the full support that it needs while you sleep.

As you know the way you hold your back at night can have a big influence on the way it feels throughout the day. If the mattress that you’re sleeping on does not optimally give the counter pressure to your back that it needs, or does not keep it in the right position, then you will feel the effects the entire following day.

On the other hand, if the mattress supports your back, then it ensures that it heals throughout the night from the pressures that you gave it through the day. The result will be there in the following day – your back will feel better and you can put new pressures on it (the ones from regular living).

So if you’re seeing a chiropractor because of a bad back, then it can be very helpful to get the King Koil mattress.

And this is why the Sealy might be a better choice: affordable strong all-around mattress

The Sealy company is more than 120 years old. The mattress has improved a lot throughout the years, because the company has always focused on innovation. One of the main reasons to get a Sealy Posturepedic mattress is also because of their spine support. So just like the King Koil mattress, the Sealy mattress is a good option if you suffer from (beginning) back problems.

Not only does this mattress support your back, but it also puts the rest of your body in the perfect sleeping position. Especially if you’re a little overweight, then you need this extra support from your mattress.

One thing to watch out for with the Sealy Posturepedic mattress is that it can be a little too firm for the first couple of days when you get it. This is normal, because it just got out of the factory. After three to four nights of sleeping on the mattress it will become softer and turn into the medium firm mattress that you were looking for.

The mattress consists of two layers:

  • The core part of the mattress is 8 inches and offers the main support. Here is where all the coils are installed.
  • The topping of the matches is 2 1/2 inches and this is the reinforced border on top of the mattress that gives you the comfort.

In general, the Sealy Posturepedic mattress is a good choice when you want a solid mattress that will support your body and give you restorative sleep at night. It’s good for people with beginning back problems or who are a little overweight and want some extra support to correct this problem before it gets worse.

Since childhood I've tried hundreds of little experiments to feel better, learn faster and perform higher (e.g. supplements, sports, psychological tricks, sleep and wacky diets).
After I graduated university in 2016, I basically found that sleep was the #1 factor to improve every aspect of life.
Bad sleep = bad life. I started SleepInvestor in 2017 to share my experiments and thoughts about sleep.
