Bonnell spring mattress systems are the most traditional type of innerspring mattress. The Bonnell coil has an hour glass shape (wider at the bottom and the top than the middle) and are interconnected with a mesh of metal to make the spring system.
In many traditional innerspring mattresses from the 20th century and still some entry level models today have used the Bonnell spring to create durable and supportive mattresses.
Though this system is good at providing even support, there are complaints of aggravated pressure points and discomfort with Bonnel spring systems.
Pros: Durable materials and traditional even feel.
Cons: Pressure point discomfort and motion transfer issues.
Latex is made from the sap of a rubber tree. Over generations, people have learned how to tap the trees without having to cut them down. This means that it is one of the most eco-conscious and sustainable ways to create bedding.
After the latex is harvested from the rubber tree, it is treated to create foam. The two most common ways of treating latex for bedding is Dunlop and Talalay. The result is a high response and heavy piece of foam that can be used for bedding. By changing the density, the latex can be more or less responsive.
Those that are used to a memory foam feel (a slow response) will be surprised to know that most latex is highly responsive, meaning that although it will react to ones body, it has a natural bounce. Some sleepers prefer this, though others not so much.
Recently, there has been an explosion in latex bedding with the higher demand for eco-conscious foam alternatives. Though latex is natural, there are some that mix it with memory foam. For those that are looking for pure latex bedding, be careful to do your research on the entire bed.
Pros: High response, differing firmness options.
Cons: High expense vs memory foam, some don't like the latex responsive feel.
