Englander Latex Mattress compared with Flobeds Latex Mattress

Latex Mattress

Our latex inner unit is the same one that is used in all of Englander's latex mattresses
sold in the Pacific Northwest. It is 100% pure latex. The ticking is a 60% cotton blend
to allow for breathability. The ticking is quilted to polyester fiber and a thin layer of
polyurethane foam to provide a deep pattern.

This polyurethane foam acts to stop air flow and maintain heat.  Poly-foam looks
like a million bucks when quilted, but doesn't last or breath....and harbors dust mites.

We also put a layer of fiber pad over
the latex unit so that the mattress retains a nice "crowned" look. This prevents the bed
from looking blocky when made up with sheets, blankets and comforter. However;
some other makers use a latex / synthetic blend. We feel that 100% pure natural latex
is superior to blends of synthetic latex. Natural latex is more resilient than blends,
thus, it will bounce back to its original shape for many years of sleeping comfort.

All FloBeds FloCare latex mattresses are made made with Talalay Latex. 
Latex International's flagship product, Talatech Latex, is a blend of 30% natural rubber and 70% synthetic rubber. Our 100% Natual Latex System is now also made by Latex International with the Talalay process. FloBeds Natural Latex is produced using no fillers or shortcuts. It is made from 100% Latex Rubber from the Rubber Tree.
Then it is poured into the latex mold..  A vacuum is applied to the mold to remove air pockets. 
Flash freezing insures consistency and will allow the Talatech Latex
to be made in variations of softness and  firmness unequaled by any other latex manufacturer in the world.
(From 4ild to 70 ild...our beds range from 20ild to 40ild) 
Then it's heated and cured which gives the latex a lifetime of support and durability.  
A five stage washer removes any residue.  It takes 3 to 4 hours to make a latex mattress core.

The Latex core is made with pincore construction which helps keeps the mattress cool in
the summer and warm in the winter.

The density of our latex foam is an impressive 3.4 lbs./cu.ft. There are 3 important
reasons for this heavy density. They are:

1. Long life. We expect this bed to have a 15-20 year service life. The more material,
the greater the life.

2. Exceptional comfort and support. Foam that is less dense must be made stiffer to
prevent full compression, or a feeling of sinking deeply into the surface. Stiffer, low
density foam is less comfortable and breaks down quickly.

3. Our Englander Latex Mattress is designed to be a premium, t-op of the line
mattress. When we designed this bed, the goal was to make the best, not achieve a
certain price. We have achieved our goal.

Latex foam unlike polyurethane foam, is poured into a mold that is the product end
shape and simply dries. Polyurethane foam is poured onto a large -table and then rises
to form a "bun" that is then cut into several finished foam products.

Natural latex foam compresses differently than poly foam. Latex compresses
throughout its entire structure as weight is applied. This equally distributes the
mechanical burden of compression and creates a soft surface with underlying
support. Most poly foam compresses from the surface, with interior compression
occurring only under extreme load. This means that the surface foam does most of
the work and is subject to wear. The bottom line in foam is that the greater the
density, the longer the foam will last. Natural latex can be made very dense and, since
it compresses through its full length, is still very comfortable.

I mentioned that our latex mattress has a density of 3.4 lbs./cu.ft. To determine this
we actually measured and weighed a foam piece to calculate density. Since our
Englander Latex Mattress features pincore construction (the latex unit is pierced with
a series of pencil diameter holes to enhance breathability), the actual material density
is somewhat greater.
