iCoil Mattress Technology vs. Bonnell Springs: What’s Inside?
Responding to an ad for blow out sale on a mattress, in the newspaper or on tv, might deliver a very unpleasant shopping experience.
Most of the mattresses advertised this way are bonnell spring mattresses and the dealer wants to attract you into the store with the cheap sounding price tag.
These mattresses are really cheap to manufacture, so lots of dealers use them as bait, in huge newspaper or tv ads, to get you into the store.
Of course, once you’re in the store, they pull the old bait and switch on you. They’ll tell you how crummy the cheap mattresses are and try to up sell you to one of the higher priced bonnell spring mattresses.
The reason bonnell spring mattresses are so cheap is because the springs are all tied together and then surrounded by a hard wire. This wire runs around the outside edge of the mattress to hold it in shape. This wire is so rigid and unforgiving that when you sleep out toward the edge of the bed, you’ll definitely feel it under you and it’s not a warm and fuzzy feeling.
Bonnell springs are hour glass shaped and they’re tied back to themselves at the top and bottom. There’s one glaring problem with this design, since all the springs are tied together, what happens on one side of the mattress directly affects what happens on the other side.
When someone flops into bed, you can be jolted clear up off your side of the bed. It’s what is known as motion transfer.
The reason for this is the iCoil mattress technology. The coils are much smaller, so there are many more of them. They’re encased separately, so that compressing one coil doesn’t affect the one’s surrounding it. There’s, virtually, no motion transfer.
Remember, motion transfer is a big deal if you sleep with someone who tosses and turns at night. When they flop down, you go up and vice versa. It’s like riding a bucking bronco in your sleep.
Another problem, with bonnell spring mattresses, is the valley. Two people sleeping close to each other will create a valley that they both roll into, colliding in the middle. This is called meeting in the valley and it isn’t a pleasant way to spend the night. If you roll into each other, in the middle of the night, you know you can’t roll back uphill to try and get to your side of the bed, you’re stuck.
This is a new technology and it seems to be a big improvement over the old technology.
