KING

A king-sized foam mattress is the ultimate in sleeping luxury, and the Slumberbox boxed mattress is the most luxurious mattress of its type. In comparison to other boxed, deliverable mattresses slumberbox mattresses are 15% to 20% heavier, which means that thanks to this extra weight they last you longer.

Not only do they last longer, but slumberbox mattresses are also made out of soy-based foam products, not petroleum-based products. As a result of this, while there may be some “new product” odour for a few days after you take your mattress out of the box, there is no off-gassing. A Slumberbox mattress is also not made of any ozone depleters, formaldehyde, phthalates, latex, and heavy metals.

It is entirely safe, and if you consider that you spend a third of your life sleeping on your mattress, you want it to be free from any kind of harmful materials. Invest in a Slumberbox foam mattress king size; it relieves pressure points that cause you to toss and turn and will allow air to flow freely around you and any sleeping partner you share your king-sized mattress with.
