King Koil's Supportiveness

You may think supportive mattresses are always firm mattresses, but when we write about support, we are describing mattresses that support the back and spine properly, independent of how firm the mattress feels. These mattresses are well rated for their supportiveness for the average customer overall, but there are some reports about degrading support over time in some King Koil models.

Edge Support
These mattresses have good support along the edges, which is ideal for those that sit on the side of the bed or enjoy laying on the edge of the mattress. If edge support is important to you, consider getting a medium-firm or firmer mattress to ensure the side of the mattress can take the focused weight of sitting down.

Bowling Ball & Density Tests
By resting a bowling ball on the mattress, you can measure how even a mattress is in terms of support. These mattresses mostly provide even support at first, but the reports of degrading durability may cause some mattresses to sag over time.

King Koil's Durability

Finding a mattress that is highly durable can save you loads of money. But, these days, everything from what you wear to where you sleep are degrading faster. Customers have mixed feelings about the durability of these mattresses. Each bed is different so one may last years for you, but others may not be so lucky. Versus Sealy, King Koil's durability scores are somewhat better, but are still a concern for some of their customers.

Sealy's Owner Satisfaction

Sealy makes a variety of mattresses, from all-foam options to hybrids with pocketed coils that provide extra support to the spine. Their mattresses also come in many pricepoint and firmness options. When it comes to comfort though, sleepers have mixed reviews. Some have found lasting comfort, but there is a sizable number of customers that describe issues getting comfortable and long term durability concerns. If you are looking for a wide range of options for a budget-friendly price, take a look at our list of best rated mattresses.

Sealy's Supportiveness

Support isn't equal to firmness. Support is great if it aligns the spine and leads to a healthy night's sleep. Sadly, some customers don't find all of the Sealy models to have great support. Most find the mattress to be comfortable at the beginning, but some folks felt like support was lacking over the long term. While both King Koil and Sealy have some mixed reviews on support at time, King Koil may have better longevity in terms of support and comfort based on the scores from customers.

Edge Support
For those that sit on the edge of their mattress in the morning, edge support is very important. For most folks, these mattresses do a good job with edge support at the beginning, but some had complaints that edge support wasn't all it could be long term.

Sealy's Durability

Sadly, not everyone rates these mattresses well for longevity. While some sleepers reported lasting comfort, others have experienced quicker issues than average. Make sure to take a look at the specifications, warranty, and reviews before buying.

Great Quality for Price

This mattress is comfy! It's not too firm and not too soft. I love it! I was a little nervous before I bought it because the price is so low. Once I went in the store and tested it out, I knew I was going to get my monies worth. Granted I've only had it for about a week now, even my boyfriend has confirmed it's super comfortale. Get it while it's on sale.

It really is a top quality innerspring mattress. It REALLY is!

I did a lot of research before buying this mattress. The deciding factor was the recommendation of Consumer Reports. When I first received this mattress, in a square box, I was soooo disappointed and upset. I attempted to return it before opening it, but realized how expensive shipping would be. I returned to the website and their were no reviews but I searched some other mattresses with the same features and price points and discovered that it would, when unfolded, rise to it's full 12 inches and it did indeed have cloth covered coils (innersprings). It Did rise, and then some. I think it's about 13". Very comfortable, everything Consumer Reports said it would be. It's a little firmer than I would like it to be. It's not hard by any means, in fact it's quite comfortable and very good for my husband's back, he likes it a little firmer than I. after putting a good quilted mattress cover on, it added just the amount of plush and squish I love. I get a good night's sleep and wake with no stiffness or aches. I really like it.
