What You'll Learn

The Sleep Number i10 Legacy mattress is 15 high
The Sleep Number i10 Legacy mattress is a premium product, standing at 15 inches high. The i10 Legacy is an adjustable air bed with an air support core. The mattress comes in Queen, King, California King, FlexTop King and Split King sizes, and each side has its own Sleep Number, allowing each sleeper to select their own level of support and adjust the air pressure in their chamber. The Sleep Number i10 Legacy is a plush mattress with comfort layers, including padding directly on the air chambers and a duvet-style pillow top. The pillow top is reversible, with 2 inches of Plushfit polyurethane foam on one side and 2 inches of memory foam on the other, giving users a choice of sleeping surfaces.
The Sleep Number i10 Legacy mattress is constructed with a single air chamber on each side, which can cause "hammocking" or sagging in the middle at softer air levels. This effect is more noticeable for heavier persons, as the heavier mid-section pushes the air to the ends, raising the head and feet. To mitigate this issue, some adjustable air bed brands offer three chambers on each side, providing targeted support for the head, mid-section, and feet while maintaining cushioning for the hips and lumbar region.
The i10 Legacy features temperature-balancing technology, incorporating Outlast material in its dual-sided duvet. This moisture-wicking technology helps regulate the sleeper's body heat, addressing a common issue with memory foam mattresses, which can absorb and retain heat. The i10 Legacy also features spun rayon ticking, quilted with 2 inches of Hypersoft Foam, enhancing its comfort and support.
The Sleep Number i10 Legacy mattress has received mixed reviews, with an average rating of 3.63 out of 5 stars on Yelp. While it offers a range of features and customization options, some users have reported issues with durability and hammocking. Overall, the i10 Legacy mattress stands out for its adjustability, temperature regulation, and plush comfort layers, making it a notable entry in the Sleep Number line of mattresses.

The i10 Legacy has a hose that connects to chambers at the head
The Sleep Number i10 Legacy is a 15” high adjustable air bed. It features an air support core and is available in Queen, King, California King, FlexTop King and Split King sizes. All i10 Legacy beds have DualAir Adjustability, meaning there is a separate air chamber for two sleepers. Each sleeper can select their own level of support, with each side having its own Sleep Number setting. This Sleep Number setting controls the air pressure in the chamber – the higher the pressure, the firmer the mattress.
The i10 Legacy mattress has comfort layers that qualify it as a plush mattress. These include padding directly on the air chambers, as well as a duvet-style pillow top. The pillow top is two-sided, with 2” of Plushfit polyurethane foam on one side and 2” of memory foam on the other, allowing the user to choose their preferred side. The ticking of the i10 Legacy is spun rayon, quilted with 2” of Hypersoft Foam.
The i10 Legacy features a hose that connects to chambers at the head. This is a key difference between the i10 Legacy and the i10 360, in which the hose connects at the hip and can be detached from the pump and chambers. In the i10 Legacy, the hoses do not detach at the pump.
The i10 Legacy has received mixed reviews, with an average rating of 3.63 out of 5 stars on Yelp. One common complaint about the single air chamber per side is hammocking, or sagging in the middle at softer air levels. This is more pronounced for heavier persons, as lowering the air pressure causes the heavier mid-section of the body to push air to the ends, raising the head and feet.

The i10 Legacy has a duvet-style pillow top
The i10 Legacy is a premium mattress from Sleep Number. It was once the top-of-the-line model in the Sleep Number range of beds. The i10 Legacy has a duvet-style pillow top, which is a two-sided duvet with 2 inches of Plushfit polyurethane foam on one side and 2 inches of memory foam on the other.

The i10 Legacy's duvet-style pillow top is designed to provide a luxurious and comfortable sleeping experience. The pillow top is filled with a combination of memory foam and Plushfit foam, which work together to contour to the body and provide support. The memory foam side of the duvet-style pillow top is ideal for those who prefer a firmer sleeping surface, while the Plushfit foam side offers a softer, more cloud-like feel.
In addition to providing comfort and support, the i10 Legacy's duvet-style pillow top also offers temperature regulation. The Outlast material used in the duvet helps to balance temperature and minimize temperature swings, ensuring a comfortable sleep environment. This is especially beneficial for those who tend to sleep hot or live in warmer climates.
The i10 Legacy's duvet-style pillow top also contributes to the overall customizability of the mattress. With the ability to choose between memory foam and Plushfit foam, as well as adjust the firmness and support of each side of the bed, the i10 Legacy offers a personalized sleeping experience for couples with different preferences. The dual-sided duvet enhances the i10 Legacy's reputation as the ultimate mattress for customized comfort.

The i10 Legacy has a single air chamber per side
The Sleep Number i10 Legacy is a 15-inch high adjustable air bed. When it was first introduced, it was the top-of-the-line model of Sleep Number beds. The i10 Legacy has a single air chamber per side, with DualAir Adjustability, which means a separate air chamber for each of two sleepers. Each side has its own Sleep Number, allowing each sleeper to select their own level of support. The air support core is topped with comfort layers, which qualify the i10 Legacy as a plush mattress. The comfort layers include padding directly on the air chambers, as well as a duvet-style pillowtop. The pillowtop is reversible, with 2 inches of Plushfit polyurethane foam on one side and 2 inches of memory foam on the other, allowing users to choose their preferred sleeping surface.
The i10 Legacy's ticking is made of spun rayon, quilted with 2 inches of Hypersoft Foam. One common complaint about the single air chamber design is hammocking, or sagging in the middle at softer air levels. This issue is more pronounced for heavier persons, as their heavier mid-section pushes the air to the ends, raising their head and feet. Lighter persons can generally avoid hammocking by using lower air pressure.
The i10 Legacy also features temperature-balancing technology, with Outlast material used on the dual-sided duvet to help regulate moisture and temperature. This is particularly important for memory foam mattresses, as memory foam tends to absorb and accumulate body heat. Other temperature-regulating materials used in the i10 Legacy include Tencel, gel, and phase-change materials. While airflow is also important for cooling, the effectiveness of airflow in the i10 Legacy mattress is limited due to the use of convoluted foam, which allows for horizontal but not vertical airflow.
The original i10 mattress, now known as the Legacy or Traditional model, has received mixed reviews on sites like GoodBed, Yelp, and Viewpoints. On Yelp, out of ten ratings, four were 5 stars, one was 4 stars, one was 3 stars, and two were 1 star, resulting in an average rating of 3.63 out of 5 stars. The Sleep Number i10 was also rated on GoodBed, with an overall owner rating of 77%.

The i10 Legacy has an average rating of 3.63 out of 5 stars
The Sleep Number i10 Legacy is a 15-inch high adjustable air bed. It was the top-of-the-line model when it was first introduced. The i10 Legacy has an average rating of 3.63 out of 5 stars. This rating is based on ten ratings of the Sleep Number i10 on Yelp, two of which were for mattresses that had not been delivered. Of the remaining eight reviews, four were 5 stars, one had 4 stars, one had 3 stars, and two were 1 star.
The i10 Legacy has DualAir Adjustability, which means a separate air chamber for each sleeper. Each sleeper can select their own level of support, with the air pressure in the chamber corresponding to the firmness of the mattress. The i10 Legacy also has comfort layers, which qualify it as a plush mattress. The mattress has a duvet-style pillow top with two sides: one with 2 inches of Plushfit polyurethane foam and the other with 2 inches of memory foam. This allows each sleeper to choose their preferred side.
The i10 Legacy offers "temperature balancing" through the use of Outlast material on its dual-sided duvet. This feature addresses the issue of memory foam absorbing and accumulating body heat. The i10 Legacy also utilizes convoluted foam, which allows for horizontal airflow. However, the effectiveness of temperature regulation depends on vertical airflow through the layers above.
The i10 Legacy has received mixed reviews, resulting in an average rating of 3.63 out of 5 stars. While some owners appreciate its adjustability, plush comfort, and temperature-balancing features, others have given lower ratings for various reasons. One common complaint is the "hammocking" effect, where sagging occurs in the middle of the bed at softer air levels, particularly for heavier persons.
