Offering great comfort & support, this open coil mattress has a number of core features that represent excellent value. The mattress uses a traditional open coil spring system, a series of interlinking coiled springs which are evenly set within a durable, ‘rod edged’ framed structure which offers excellent support & also helps to maintain the support & shape of the mattress for years to come. For comfort, it is layered on both sides with a supportive filling & has button tufts to provide soft to medium comfort. Practical & versatile, this open coil mattress is covered in an anti-allergy treated fabric making it 100% dust mite free & suitable for allergy sufferers. Its shallower depth makes it perfect for a bunk bed mattress or trundle guest bed. As both sides feature the same fillings, it makes both sides equally usable, so you can flip the mattress regularly to keep it functioning at its optimal level.
