Van: One of the strongest innerspring units manufactured is the Hinge-Flex by Leggett and Platt. You can find that in products like the Exceptional Touch line (disclaimer: I carry the Exceptional Touch line) or the XL line from King Koil. You'd want to combine that with a premium type of foam, whether it be high-resiliency polyurethane foam or a denser, mid-to-higher ILD latex foam. A too soft latex foam, even if it is good quality, will not be as durable, so be sure to check into that. This would be a good starting point for you.

I talk about these components in a non-brand specific manner in my Beducation videos (see "Mattress foam firmness scales" for example) if you want to do a little more research. Best of luck. Jeff

Hi Van, Most people feel a firmer mattress is the strongest and will last the longest. A firm mattress will stress your body which will make you toss and turn more often at night. Today you have Memory Foam, Innerspring and Latex on the market that are able to give the support needed ... I carry all on my mattress site ... but I believe the mattress that will satisfy you the best is our 100% Seven Zone Latex mattress. It has a solid Latex Core not just a 1" latex padding on springs. If I have a friend that is heavier ... I will only suggest a Latex Core mattress. It will be supportive and still have the comfort to relieve the pressure on you body. Latex is cooler than memory foam and will resist BODY impressions. I would be happy to talk to you about any concerns you may have and share 35+ years experience with mattresses. You can also take a look at my Latex mattress page here.

Hi Van,

Although memory foam is quite good for many people and really does outlast most coil mattresses for body impressions, it's not for everyone. In my experience, plus-sized folks find it difficult to move in a memory foam mattress. If heat is an issue as it is for many folks, you will not be happy with memory foam.

Rather than focus in on the amount of coils in a king, ask what the gauge of coil is. Remember that the more coils there are, the thinner the wire, which is a higher gauge (18-20). Although there is a lot of steel in this kind of bed, the tiny pocket coils will not support a plus sized person well. Fewer coils (without going too few) have a thicker wire, which is a lower gauge (12.5 to 14) is much better to support a plus size frame. The number of pocket coils in this type of a king mattress should be approximately 1100-1300.

However, in my opinion, I think your best bet would be latex. You can get support without sacrificing comfort. Latex is breathable, so it runs cooler than memory foam, durable (LatexBLISS mattresses have a 20 year NON-PRORATED warranty), and uber comfortable! Choose only a mattress that is completely latex, NOT a 2-3 inch layer of latex over polyurethane foam base. These beds are cheaper but will NOT last for a plus sized person.

Hope this helps!

I would avoid coils also, the do eventually break down and the super soft foams on top of it break down even quicker.

Many people are recommending their latex mattresses. I agree latex is the best as long as it is not a synthetic blend and there is no polyurethane foam in the mattress.

I have tried many different latex producers in the USA. I import mine by the container because I like the density better. Yes, it is a large investment for our company but worth it because we feel it is a better product and doesn't feel like foam. Feels more dense, hence will last longer because density = longevity. I would be happy to send you a sample.

Hi Van,

Not all foam is created equal. The indentation issue you speak of is indicative of Tempurpedic type foams, 5lb to 7lb foams. Bed In A Box mattresses use a 3lb foam that provides support and cushioning without the indentation.

I carry them in my stores, and highly recommend them.

It's no secret here I am not a fan of coils. Coils are metal and cause pressure. Not the best basis for sleep.
