Answers before you order

What is included?
One Cosmic adjustable base in your selected size and a wireless remote. Mattress and decorative bed frame are sold separately.

Will it work with my mattress and bed frame?
Check your mattress manufacturer's adjustable-base compatibility and compare your frame's interior measurements with the table above. Contact 5th Avenue Furniture & Mattress if you would like help checking your setup.

Is Twin Long the same as Twin XL?
Yes. The Twin Long option on this listing is Ashley's Twin XL model. The King option is a King-size base; it is not a pair of Twin XL bases. For a split setup, contact us to confirm the quantities and mattress arrangement you need.

What is the weight limit?
Ashley's M8X2 manual recommends a maximum total load of 700 lb, including the mattress, evenly distributed across the base.

Does it need assembly?
Assembly and setup are required. Follow the manufacturer's instructions for installation and safe operation.

What warranty comes with it?
Ashley lists a 3-year limited warranty with labor coverage for this model. Manufacturer terms and exclusions apply; contact us for coverage details.
