Sleeptek Kama Flex Float

The Kama Flex Float mattress by Sleeptek is a customizable mattress made with the classic configuration of three different layers of organic rubber. The mattress is made from 8 inches of GOLS certified organic latex rubber; two inches for the bottom layer, four inches in the middle and two inches on top. The bottom layer is the foundation layer of firm natural rubber. For the middle layer, choose soft, medium or firm to create a softer mattress, one with firm support, or something in between. The two-inch top piece is always extra soft Dunlop latex for ultimate pressure point relief. The organic rubber is encased in an organic cotton and wool quilting cover: stretchy organic cotton knit on top and organic cotton canvas on the bottom.

4 inch Middle Layer Firmness Level

Please select your desired firmness level.
There are three firmness options for the middle layer: soft, medium, and firm. If you would like your firmness level different on each side, please choose, for example “Firm/Medium” for firm on one side and medium on the other. If you would like the same firmness level on each side please choose, for example, “Medium/Medium” (please note, latex can not be different on each side of Twin or Full mattresses).

More about the Kama Flex Float Organic Mattress

The Kama Flex Float organic rubber mattress by Sleeptek is constructed of 8 inches of natural rubber. On the bottom is a 2 inch layer of firm (38-42 ILD) natural rubber. In the middle, is a 4 inch layer of soft (22-24 ILD), medium (32-35 ILD), OR firm (38-42 ILD) natural rubber. On the top is a 2 inch layer of soft (22-24 ILD) natural rubber. For the middle 4 inch layer, you can choose different firmness layers on either side. Each layer is individually wrapped in organic cotton tricot and then surrounded by organic cotton quilted to pure wool.

The Kama Flex Float mattress cover features a stretchy organic cotton jersey knit on top, which allows the natural rubber to better contour to your body. The organic cotton jersey knit is quilted to 2lbs/square yard of organic wool. The bottom of the mattress cover is made from organic cotton canvas quilted to organic wool. As a secondary option, this mattress can be configured with the canvas side facing up: sleeping on the canvas side will yield a slightly firmer feel than the knit side.The organic cotton and wool cover is removable to air out the mattress.

The pure wool acts as a natural flame retardant, so no chemical flame retardants are added to this natural mattress. Pure wool and natural rubber are dust mite and mold resistant.

The Foundation

The 4″ or 7″ wood slat foundation supports your mattress using solid wooden slats and is covered with the same organic cotton as your mattress.
The wood is untreated pure seasoned kiln-dried spruce; no synthetic glues, dyes, or finishing sprays are used in any stage of production.

Pictured below are optional 8 inch wood legs (additional charge will apply) that can be attached to the foundation such that the mattress and foundation can be used without a separate bed frame. Please call to order.

Comfort Guarantee

If the comfort level you choose is not exactly right, you can later purchase a new 4″ latex core in a different firmness level.  For example, if you choose “firm” for your middle 4″ layer, and after sleeping on the mattress for a while, you realize it is a bit too firm, you can purchase a new 4″ core in firmness level “medium” or “soft”.  This is not an exchange, so you get to keep both the new latex and the original latex in case you should ever need to switch it again. Comfort guarantees must take place within 6 months from purchase date.
