Abstract: A mattress comprises one or more cavities disposed within the mattress. A filter assembly is removably mounted within the cavity at a first distance from the mattress' upper surface. One or more channels are disposed laterally within the mattress and connect the cavity to the mattress sidewall so that intake air is allowed in and exhaust air can escape. In one version an aroma assembly is also removably mounted within the cavity. Within the channels there may be disposed one-way valves to allow air to flow only in a first direction or a second opposite direction so that exhaust air is not mixed with intake air. A fitted sheet used in combination with the mattress may include a sleeve corresponding in size and location to the cavity, where the sleeve is made from an odorless washable material. The sleeve may be retained within the cavity by a plastic ring.

Abstract: A collar or harness for an animal comprising a first loop sized and shaped to be secured around the neck of the animal. A second loop is attached to the first loop at a securing point. The second loop is selectively movable between a stowed position wherein the second loop is located around the neck of the anal, adjacent to the first loop, and a usable position wherein the releasable portion of the second loop is located remote of the securing point so that the second loop may function as a lead.
