What is a Bonnell Spring?

Hi Andrea,

Thank you for your question.  HD (High Density) Pocket Springs or Micro springs are small pocket springs in spun bond material that bed manufacturers use to vastly increase their mattress spring count. You can fit thousands of these in a mattress as they are only about an inch in depth. However, what they don't tell you is that in most cases these tiny springs are pretty much useless.

Yes, that's right. They compress so quickly due to their size so once you're on top of the bed they completely compress providing no real support at all. They also take up valuable space in a mattress where upholstery should be to provide lasting support and comfort.

You're better with a full-size pocket spring and more upholstery in our opinion.

Calico encased pocket springs, with the tension correct for your bodyweight, can give you the right level of support and are more breathable than those in spun-bonded materials. Just think all those thousands of springs are taking up space where sumptuous upholstery layers can give you the feel you prefer and as natural fibres are more breathable and durable your mattress will last longer. And given the weight of all that extra metal, it would be more difficult turning the mattress on a regular basis.

Have a look at our Artisan range, which most are constructed with Calico pocket springs and all have Natural Fibre content from 53% to 100% suitable for all preferences and budgets.

I hope this helps and if you would like any further information or would like to discuss the suitability of any of our mattresses, please do not hesitate to contact the office on 0161 437 4419.

Hi Eddie.

Thanks for your question on what is a Bonnell sprung mattress. Bonnell springs go by many guides such as Open coil, Cage Sprung, Miracoil Posture tech and Traditional spring to name a few.

The Bonnell mattress-guide/" title="spring">spring you refer to means its a 13.5 gauge one piece cage sprung mattress (open coil - not pockets) I had a quick scan for the item you mention and cannot find a double for the price you quote. This type of spring is the most basic possible in a mattress and is mass-produced.

The Bonnell or open coil spring unit is the cheapest and most ineffective support unit you can get in a mattress. It is a continuous piece of wire that is twisted and coiled to create a massive set of joined crude springs. This results in a 'one size spring' of sorts, which moves as a mass piece. So when you move the whole bed ripples and shakes with you. There is mass transference and no isolation in the spring unit as it compresses. We have more detail here on why open coil mattresses should be avoided.

We only sell pocket spring mattresses and have never sold continuous coil mattresses. if you're looking at which models to start looking at why not view our two best sellers as a place to start. The Origins 1500 or the Artisan Naturals Mattress in our Shop. Pocket springs allow the most independent support as each spring acts on its own, rather than as one big massive spring like the Bonnell. Pocket springs can also be tailored to your weight with spring gauges, whereas a Bonnell coil is nearly always a one size fits all (or fits no one in reality!).

To help you with what to look for in a quality mattress we would ask you to start by looking at the Origins 1500 mattress. When mattress shopping and working out how to choose a mattress you need to start by asking exactly what is inside each mattress. The listing of this mattress will show you how to start uncovering what's inside a bed.
