Reasons to ditch springs

We’re experts when it comes to round mattresses, so we’re always asked what’s best, new age memory foam, or traditional springs? Given the huge advances achieved with foam technology over the past decade, it’s no surprise that we’d always pick a memory foam round mattress. Sprung mattresses can lose up to 16% of their support in the 1st year alone, not to mention that each spring pushes back into your body with equal force meaning pressure points are inevitable. A quality memory foam mattress on the other hand distributes body weight evenly and reduces pressure by up to 80%. Memory foam also offers no motion transfer or partner roll together helping you get a better nights sleep.

When it comes to custom and odd sizes for your round mattress, memory foam wins again, with springs becoming somewhat problematic. You can’t have half a spring, so the size of your mattress has to be made in increments based on the size of each spring – not to mention that the added complexity results in higher production costs. Memory foam on the other hand can be cut to any size, and a simpler production process gives better value for money.

    Custom Size Beds are a leading mattress manufacturer, renowned for high quality mattresses in the UK and across Europe. We recognise that finding the perfect sized mattress for round spaces can be challenging, which is why we provide mattresses manufactured to your requirements.

    Whether you’re looking for a large round mattress, a mattress with a corner cut away or some narrow small bunk beds, Custom Size Beds are happy to work to your exact dimensions. Made with comfort and convenience in mind, we guarantee a good night’s sleep every time. We can even offer custom size fitted sheets to fit your new round mattress.

    We deliver high quality, unbeatable service. We have a friendly and knowledgeable sales team that can match you with your perfect mattress. To give you peace of mind, we provide you with a scale diagram of your round mattress for you to review for any last minute changes. This is to ensure you are 100% satisfied with your order that will fit just right, before it is tailor-made and shipped to you within a few working days.

    The journey to a good night’s sleep begins with a quality and reliable mattress. Having a good night’s sleep is too important for your health and wellbeing to be neglected. Wake up feeling refreshed and ready for the day, whatever you plan. Whether you’re at work, home or school, you’ll want to feel well-rested to seize the day. Each of our mattresses are specially engineered to support your body where it needs.

    Operationally efficient and productive, our manufacturing centres allow for a quick turnaround between order and delivery. Once the final requirements for your circular mattress have been received, we use IT technology to measure and cut your dimensions perfect to your measurements. Once completed, a quilted cover with a zip is fitted by our expert craftsman to ensure it can be easily removed if needed. All completed mattresses are sent directly to your door via a next day express courier, to get your dream mattress to you as soon as possible.

    If you can draw it, we can make it! If you’re unable to draw it for us, you can send a full size cutout of the measurements you need and we can work from there. Difficult to source mattresses become easy to find at Custom Size Beds, including round and oval shaped mattresses.

    Any mattress can be challenging to fit and secure correctly. This is why we vacuum pack every round mattress and roll them all too prior to dispatch. Your mattress will now fit through narrow spaces whilst remaining protected during transit, guaranteeing easy installation. Simply unpack, and it will unroll. Wait 5-6 hours and your mattress will be ready for the perfect night’s sleep.
