Helix Foundation review

Helix sells a plain spruce foundation that stands out for how quickly it goes together. Helix says it can be built and broken down in 2 to 3 minutes with no tools, which is the fastest figure any maker on this list publishes. The slats sit 3.5 inches apart, closer than Bear's 4 inches, and the corners are rounded. You can pick a standard 7.5-inch or a low profile 5.5-inch height, in charcoal or natural. A standard queen cost $359 with a 20% code when we checked, down from $448.75. Helix ships it free in the contiguous US from California, Texas or North Carolina, separately from any mattress. The terms are shorter than the leaders: a 30-night trial with free returns and a 5-year limited warranty. That is fine for a simple wood base, but Purple and Sealy both offer 10 years. Helix also suggests pairing it with a frame for extra height and storage.
