Many of the mattresses that are on sale from the top brands like Serta, Simmons, Sealy and so-on are capable of supporting heavier individuals. However, you'll find reviews that suggest that some are better than others. For example, the Sealy Posturepedic mattress has received a lot of positive feedback due to its sturdy and durable construction.
The core or foundation of the mattress is what contributes greatly to its ability to support heavy people. Like many products, you often get what you pay for. Higher quality mattresses are usually at the higher end of the price scale, so if you buy cheap, bear in mind that long-lasting support may not be one feature that's guaranteed.
The main difference between buying a mattress for an overweight person versus someone with an average weight is going to be the support system. This will need to be firm as the pressure being applied to it is going to be greater. Although many people tend to feel they're limited by choice of mattress for a heavier person, this isn't the case. There are a number of options, which I will cover in more detail below.
Increasing Comfort with Mattress Toppers
Whereas you may only be shopping for a mattress, mattress toppers can contribute greatly to the overall comfort of a sleep system. You could choose to buy a cheap firm mattress or splash out on a more expensive one to create the foundation of the sleep system. Keep in mind however that as a general rule cheaper mattresses do not last as long as top of the range models. Then, adding a latex mattress topper you can relieve pressure points and give extra support to the sleeper.
Choosing the Type of Mattress
The type of mattress you prefer may come down to personal preference and options available to you within budget. Air mattresses might be an option but you could face the problem of it not being firm enough to offer proper support.
Memory foam is one of the more popular materials among bed buyers these days and for good reason. They offer body contouring support and relieve pressure points well. Again, the mattress needs to be firm so a higher density memory foam mattress might be your best option. An alternative which offers similar feel is a latex mattress. These offer slightly different firmness and support, so are also worth checking out before you go ahead and buy.
No matter whether you deem yourself obese, overweight, large or fat, there are plenty of options available to you. Many people have the same problem, but the shear number of manufacturers providing mattresses means there are types and models that will meet your needs, especially when combined with other bedding products for sale.
