Frequently Asked Questions

  • We use an in-home delivery service to deliver these products. Once you place your order, they will call you to schedule your delivery. Delivery is typically within 7 business days from the day you placed your order, with metro areas usually faster than rural areas. When they deliver your new bed, they will set it up in your bedroom and remove the packing materials. They will even remove your old mattress and box spring, unless you ask them not to.


    The mattress does not come with a base or foundation, but you can purchase either one to support your mattress. Box springs cannot be used with our mattresses, and will void the warranty. You can also place the mattress into your bed frame, provided the bed is structurally sound, and has either a flat surface or slats that are at least 3" wide and no more than 4" apart.


    While your mattress does come with a cover, it is not a waterproof protector for the mattress. We recommend purchasing a mattress protector that will keep your mattress safe from liquids, humidity, mites, and anything else that might harm the mattress material.


    Any brand of sheets will work for our mattresses, but ours will be best. The corners of our fitted sheet will have patented straps to keep the sheet tightly and neatly in place, resulting in less wrinkles and less re-adjusting.

  • All of our models are designed to provide proper support. Whether you choose firm, medium, or soft is a personal comfort preference. The softer models allow you to sink into them further before you are cradled by the support layer. Back sleepers tend to prefer a firmer mattress, while side and stomach sleepers tend to choose a medium to soft mattress. We strongly suggest visiting a local retailer before making your final decision in terms of feel.
