Starting from the 1930s, when the first spring mattresses came into being, the industry in its entirety has come a long way.
The innerspring mattresses have gone through a lot of innovation, style changes, and functional modifications as well.
These changes and innovations resulted in the development of different types of innerspring mattresses.
Here are the different spring mattress types:
Open coil mattresses
Open coil mattresses, also known as Miracoil, Continuous coil, or Standard coil mattresses are the most common type of spring mattresses.
The core of the mattress is made up of an interconnected spring system.
Open coil mattresses are the most affordable owing to their traditional production process. 🤑
They can be mass-produced in a factory setting thereby incurring the lowest production cost.
The usual open coil mattress has around 300 coils in it.
Open coil mattresses tend to have a lot more “give” than the modern pocket spring mattresses. They are also good for orthopaedic use. ⛑️
Disadvantages of open coil mattresses
However, after prolonged use, they develop a dip in the centre.
Moreover, as they are interconnected, movement on one side of the bed can be felt on the other side.
They are good for children but need to be replaced every four to five years. 👶
Bonnell spring mattresses
Bonnell spring mattresses are often referred to as traditional spring mattresses.
Bonnell springs are hourglass-shaped springs with open round ends on both sides.
These hourglass-shaped springs are interconnected at the core of the mattress and thereby prevent any individual movement of the Bonnell springs.
Bonnell spring mattresses are strong, durable, high resilience mattresses.
They offer standard support to you when you doze off. 💪
A huge plus they have is that they're one of the cheapest mattresses available in the market.
They might be your go-to pick only when you are on a tight budget.
Disadvantages of Bonnell spring mattresses
However, there's not much elasticity on offer here, hence it doesn’t quite relieve your body ache, but aggravates it.
One side’s motion gets easily transferred to the other side, so it is not ideal for couples, or for siblings who share the bed for that matter. 👫
These are also not apt for people who sleep on their sides.
Pocket spring mattresses
Pocket spring mattresses are a new type of mattress.
The springs in these mattresses are individually covered in fabric pockets.
Unlike open coil structures, these coils or springs are not connected to each other.
Hence, they can move independently.
This unconnected system provides better point elasticity and motion isolation.
Motion from one section of a pocket spring mattress does not get transferred to the other side.
Two people can share the bed without disturbing each other’s sleep. Evidently, they are perfect for couples. 💑
Mechanism of pocket spring mattresses
The heavier parts of your body exert more pressure on the mattress than the lighter parts.
As the springs are not connected, the portion under heavier load sinks a little lower than the lighter parts, keeping your body in a straight line.
This aids better sleep and better posture and keeps your spine perfectly aligned.
This is particularly beneficial for people who sleep on their sides.
These people have a major disadvantage on the Bonnell spring mattress but the pocket spring mattress sinks in particular places under heavier weight and keeps their spines straight.
Barrel pocket spring mattresses
The barrel pocket spring mattresses are very similar to the pocket spring mattresses.
The only difference is in the shape of the coils.
The shape of the spring in the barrel pocket spring mattress resembles a barrel.
These springs are wider in the middle and narrower towards the ends.
They also have certain added benefits over pocket spring mattresses.
Due to the shape of the springs, they are slightly more comfortable and they feel softer.
From an orthopaedic point of view, they can be very beneficial for the patients.
