Why choose the Ashley Sleep Hybrid 1400 Queen Mattress M43731?
The Ashley Hybrid 1400 M43731 offers an ultra-plush alternative to the firmer-feeling Hybrid 1300, combining latex foam, response memory foam and whisper foam for layered cushioning above a supportive coil system. Its 720 individually wrapped coils help distribute support and limit movement between partners, while two rows of heavier perimeter coils reinforce the mattress edges. At 14 inches thick, Hybrid 1400 is one inch taller than Hybrid 1300, a useful distinction when considering bed height and fitted sheets. Adjustable-base compatibility adds flexibility for shoppers choosing a compatible foundation. The model was also offered in California King; each size has its own SKU.

What makes the Ashley Hybrid 1400 M43731 ultra plush compared with the Hybrid 1300?
Ashley rates the Hybrid 1400 M43731 as ultra plush, compared with the Hybrid 1300's plush comfort level. The 1400 adds latex foam alongside response memory foam and whisper foam, creating a different cushioning combination above the wrapped coils. It may appeal to sleepers seeking a softer surface, including side sleepers who prefer more shoulder and hip cushioning. Both models use a 720-coil support system in Queen size, so the distinction is largely in their comfort layers and intended feel. Understanding
how softer cushioning affects sinkage and sleeping-position preferences
can help determine which model better matches your needs. Comfort remains individual rather than guaranteed by the firmness label.
How do the 720 wrapped coils and reinforced edges of the Ashley Hybrid 1400 Queen mattress work?
The M43731 combines 720 individually wrapped 15-gauge coils with two perimeter rows of heavier 13-gauge coils. The interior coils respond independently to help reduce motion transfer when a partner changes position. The reinforced perimeter provides additional resistance near the mattress edges, which can help when sitting or sleeping closer to the sides. These are different functions: edge reinforcement does not guarantee a rigid edge, and wrapped coils cannot eliminate all movement. The importance of
how movement transfers between the mattress and its supporting bed frame
also explains why a stable foundation matters for couples.
Is the 14-inch Ashley Hybrid 1400 M43731 compatible with adjustable beds, and is it still available?
Ashley lists the Hybrid 1400 M43731 as adjustable-base compatible, but the Queen model is discontinued and shown as out of stock in the supplied manufacturer listing. Its 14-inch thickness would place the mattress top approximately 26 inches above the floor on a support surface 12 inches high, before compression. When considering
the differences between adjustable foundations and conventional bed frames,
check compatibility, finished bed height and mattress support requirements. If remaining stock is available from a retailer, the mattress ships compressed in a box and requires up to 48 hours to expand. Confirm the warranty terms and availability before ordering.
