When testing mattresses, key factors like firmness, feel, and performance are assessed. The best hypoallergenic mattresses are chosen after verifying that all materials are allergy-safe, and examining how each layer contributes to its hypoallergenic qualities. Factors such as durability, body type accommodation, sleeping positions, motion isolation, edge support, and temperature regulation are also considered in the testing process.
The firmness of each mattress is evaluated by lying on it and simulating sleeping in various positions, such as stomach, back, side, and combination. The construction of the mattress is analyzed to determine how soft or hard it feels compared to others. The feel of the mattress is assessed by touching and feeling the material to understand its characteristics, such as being light and bouncy like latex foam or slow and dense like memory foam.
Durability is an important factor in choosing a mattress, as beds with steel coils are typically more durable and stronger than all-foam mattresses. Body type accommodation is also considered in the testing process, as the construction and feel of the mattress are used to determine how well it will support different body types, including heavier or lighter individuals or couples. Hybrid mattresses with steel coils are usually more supportive and longer-lasting for those on the heavier side.
Different sleeping positions are tested on the mattresses, including side, back, stomach, and combination positions. Motion isolation is evaluated by jumping and bouncing on the mattress to see how much movement can be detected throughout the bed. A cup of water may also be placed at the edge of the bed and bounced around to assess how much it moves. Edge support is analyzed by physically laying on each edge of the mattress to gauge how well it keeps the sleeper feeling sturdy.
Temperature regulation is an important factor for hot sleepers, and mattresses are tested to determine how cool they sleep. The materials and construction of the mattress are considered, as well as any special technology added by the brand to make it sleep cooler. Overall, the testing process for mattresses involves a thorough assessment of various factors to determine the best hypoallergenic options that meet the needs of different individuals based on their firmness preferences, body type, sleeping positions, and temperature requirements.
