King Koil Xtended life has a 15 year 1/2” depression warranty, it’s usually our go-to when people want springs and are worried about sagging.

Not necessarily, there’s things that are way more important to consider than just cost. However, usually Beds with the following you’re not gonna buy for $1000. My dad and I do not have to sell what’s stuck in front of us by management. About 25 years ago, we made the decision to step away from the highly hyped big name labels and focus on build quality. For a time, we carried King Koil’s Extended Life line (XL). It was marketed as a heavy duty mattress for plus size sleepers, and it did use stronger coils and foams than typical brand-name beds. But when King Koil was bought out by an overseas investment group, the focus shifted. That’s when we decided it was time to move on. We also carried Campbell Mattress out of Cape Girardeau, Missouri, a company that started in 1933. After their owner, Norman Woods, passed away, it was never quite the same. What made Campbell stand out was their use of hardwood in the foundations (like poplar), 2 sided builds, and natural materials like cotton. Today we stand with Therapedic’s Medicoil HD, built in Rock Island, Illinois. Build can vary slightly by franchisee, so it’s important to do your homework and learn how a mattress is made just like we did. Here’s why we chose Medicoil HD and stayed with it. Two-sided mattresses you can flip and rotate. High-density foams that hold up. 12.5-gauge steel coils — the heaviest available. Super-duty foundations with longitudinal I-beams and 14 slats, built strong enough to support a 1300-pound soft-sided waterbed. Mattresses engineered to support 350 pounds per sleeper side. For us, it’s never been about chasing brand names. The best advice I can share is to understand and learn how a mattress is built, and choose one made the right way. That is the only way to get the lasting quality we demand for ourselves and our customers.

You don’t need a “big persons bed” the foams on all those beds aren’t going to really last longer, or they would put a better warranty on it. If yo are dead set going for a bed that is geared towards heavier people look for the Xtended life from King Koil. They have a 1/2 in depression over 15 years to get 100% replacement. Best warranty I have seen in 19 years selling mattresses. My worry, is you seem to like a softer feel and even the Overture pillow top (line of Xtended life) is only a true medium. But, don’t buy form just cause you think it will last longer, just going to create new issues

Neither bed is going to help you sleep cool at night. At this price point the beds aren’t helping you sleep cool, they are keeping you from sleeping hot. Big fig is going to KILL your shoulders. If you have shoulder pain you should not be looking medium firm to firm; you should be medium to soft. Big Fig is also going to kill your husbands hip. These beds “geared towards bigger people are just beds with less foam on them usually. The reason they “hold up better” is because there is little to no padding to break down. If you are dead set on finding a bed for a bigger person look for the King Koil Xtended life pillow top. It has the best warranty of any mattress I ever sold, and a really decent support unit. But it has a pillow top so it will help with pressure point issues you both have.

I recently bought a mattress and I'm glad I went to some stores and tried them out first. I learned I don't like memory foam. I ended up getting a King Koil hybrid latex and I love it. It was expensive, but my back pain has almost completely disappeared so I'm not too mad about it. I found a few stores too that had examples of online bed in a box mattresses so you could try them first.

Bought a King Koil latex mattress for $3k. Less than 1 year, there was sagging in the middle.

I have been telling this for years, bought a super premium 12 inch foam mattress and I used to sink in it, the only saving grace was their return policy, went to the local market and got a spring pocket mattress from King Koil.
