That is what you get with the Giselle Beddings Bonita Euro Top Bonnell Spring Mattress.Bonnell spring system uses springs that are hourglass-shaped rather than all of the same diameter. The result is a somewhat firmer mattress than a pocket spring version. The benefits include better support for your body more resilience and better ventilation. Our mattress delivers all of the above with a level of comfort that surpasses your expectations. The mattress is meticulously constructed with layers of premium materials. High-density foam fills the inside of the mattress in between the stable Bonnell spring core while the exterior is fully wrapped with a luxurious polyester fabric. Not least a soft quilting layer rests on top of the entire ensemble. Essentially you get a solid mattress that retains its shape well for long-lasting use and yet supple and comfortable to enjoy al
