This Starlight Beds Deep European Single White Big Brick Memory Foam and Spring Mattress has been carefully constructed with a European-engineered Bonnell open coil spring unit to allow the weight of the sleeper to be distributed evenly across a wide surface providing a much more comfortable and medium soft feel. Allowing the sleeper to wake up each day feeling relaxed and revitalised. The fabric of the mattress has been designed to be breathable with hypoallergenic and anti-dust mite fillings for a cleaner healthier sleeping environment. This will keep your mattress odour-free. With new in-house technology your mattress will come vacuum-packed, rolled-boxed, making it much more environmentally friendly.
