Written By: Michal Szlas - Founder and CEO of Otty Sleep The choice between an open coil and a pocket sprung mattress can make all the difference to your sleep quality. If you've ever found yourself puzzled by these terms, you're not alone. What's the difference between the two, and which is most suitable for you? What's An Open Coil Mattress? Open coil mattresses, also known as Miracoil, Continuous coil, or Standard coil among other names, have an interconnected spring system. They feature coils that are "open" or interconnected, forming a uniform structure across the mattress. Each of these mattresses consists of a single piece of wire that's twisted to form a vast spring structure, providing the characteristic "bouncy" feel of traditional spring mattresses. To provide a numerical perspective, a typical double open coil mattress would house about 300 springs on an average. Although popular, open coil mattresses have their own trade-offs. The interconnected nature of the springs means they move in unison, which can be a little disruptive for some. On the other hand, the open coil model is budget-friendly, making it a viable choice for those wanting a decent sleep solution without spending a fortune. Key Features of Open Coil Mattresses Inter-connected Spring System The open coil mattress boasts an interconnected spring system which stems from its traditional manufacturing method. Orthopaedic Support Notably commended for delivering excellent orthopaedic support, these mattresses are admired for their firmness. They can offer more 'give' compared to pocket sprung mattresses, making them a popular choice for orthopaedic use. Lightweight Design With a lighter weight, open coil mattresses can be easier to manage and turn, contributing to their practical appeal. Economical Choice Because these mattresses can be mass-produced at a low production cost, they tend to be one of the cheapest models available on the market. Durability Concerns On the downside, open coil models may not be as robust as other options and could develop a 'dip' in the middle after prolonged use. This factor can influence the lifespan of the mattress, typically lasting between 3-5 years before needing replacement. Knowing when to replace your mattress is vital here. What is a Pocket Sprung Mattress? A pocket sprung mattress, is a type of mattress that employs a unique spring system. Unlike traditional mattresses, this model uses individually housed springs in separate fabric pockets, hence the term "pocket sprung". The use of individual springs differentiates this mattress model from others. Each spring operates independently, helping the mattress adapt to the body's different pressure points. This feature results in enhanced comfort and support. Not to mention, it's an ideal option for people sharing a bed, as traditional sprung mattresses intelligently respond to individual weights and movements. Our in-depth guide to pocket spring mattresses can enlighten you further. Key Features of Pocket Sprung Mattresses Independent Springs In a decent pocket sprung mattress, each spring is independent, offering unmatched support exactly where it's needed. Tailored to Your Comfort Its flexibility can adapt to any sleeping style. Individual spring action allows micro-adjustments in response to one's body shape, sleep position, and movements during the night. Excellent Edge Support Higher-end pocket sprung models can provide commendable edge support. If you prefer sleeping near the edge, you won't be tipped out. Adapts to Different Weights Pocket springs could be tailored to varying body weights. Therefore, a mattress can have two different tensions, making it perfect for sleepers of different weights. Longer Life Span A significant advantage of pocket springs over open coil is their longer life expectancy due to superior overall support. A pocket sprung mattress can last for 7-10 years. Key Differences Between Open Coil and Pocket Sprung Mattresses Support System Comparison Open coil mattresses use interconnected springs, which means if one spring moves, they all move. This can lead to an uneven distribution of support, especially for partners of different weights sharing the same bed. Find out more with our mattress guide for couples. Pocket spring mattresses feature individual springs enclosed in their fabric pockets. This design gives precise contouring of the body, providing edge-to-edge support. Each spring works independently, which significantly reduces the 'roll-together' effect. Price Point Comparison Pocket sprung mattresses come at a premium due to the advanced construction. You wouldn't likely find a genuine pocket spring model for under £350. Open coil mattresses are more budget friendly, in the £250-£400 price range. These mattresses are relatively cheaper, but this doesn't necessarily translate to value for money. At higher price points above £500, some retailers attempt to disguise open coil springs under innovative names, trying to suggest better quality. It's crucial to be aware of this marketing ploy, as you should expect more from your investment. Investing more in a quality pocket sprung mattress, like our Otty Pure+ Hybrid 4000 Pocket Sprung mattress, is a better move in the long run. Durability and Lifespan Comparison Pocket sprung mattresses are known to withstand the test of time more efficiently due their advanced construction. Each spring works independently, distributing the weight evenly across the mattress, resulting in less wear in specific areas. Open coil mattresses, although usually more affordable, don't present the same durability. It's important to highlight that all the springs in an open coil mattress work as a single unit, which means consistent pressure on the same spots night after night. This intense stress may cause a quicker sagging or dipping in the mattress. The average lifespan expectancy varies considerably between these two types. A pocket sprung mattress can last between 7-10 years, offering reliable support and comfort over time. On the other hand, the open coil mattress lifespan tends to be shorter due to its structure and working mechanisms. Which Mattress is Better for Your Needs? When deciding what mattress is better for your needs, you first need to understand your unique sleep requirements. Comfort should top your priority list, encompassing features such as support and resilience to partner disturbance. Open coil mattresses may seem attractive due to their budget-friendly nature, but their lack of individual springs often fails to provide the desired spinal alignment and support. Pocket sprung mattresses, with high spring counts up to 5,000, offer a more personalised sleep experience. Each pocket works independently to provide superior comfort, alignment and support. They reduce partner disturbance, an aspect most appreciated by those sharing a bed. Remember, the higher the spring count, the better the mattress contours to your body, delivering unmatched support. Final Thoughts on Open Coil vs Pocket Sprung Mattresses The choice between an open coil and pocket sprung mattress largely depends on your individual needs and preferences. If you're after a mattress that offers plenty of support and reduces partner disturbance, a pocket sprung mattress might be the right choice for you. However, if you're on a budget and still want a quality mattress, an open coil model could be a decent option.
