Here are some of the most popular questions that we get asked by our customers.
Do I need a boxspring for this mattress?
Usually, no. Most customers use a solid foundation, platform bed, or an adjustable base.
If you’re using a traditional bed frame, you may need a bunkie board or a supportive foundation for proper support. If you tell us what bed frame you have, we’ll help you match the right setup.
How does delivery work?
After you purchase, we’ll coordinate a delivery time that works for your schedule.
Delivery, setup, and disposal are available. In-store, we’ll confirm what you’d like included and any access details (stairs, tight hallways, etc.) so delivery day is smooth.
Will you dispose of my old mattress?
Yes—old mattress disposal is available when we deliver your new mattress.
Just let us know at checkout so we plan the truck space and the right team for the job.
How long is the warranty and what does it cover?
Most warranties are 10 years, but some are 12 or 15 years. Your mattress warranty covers manufacturer's defects. Each manufacturer has different warranty guidelines.
Can I return my mattress if I don't like it?
Most mattresses includes a 120-night trial.
Because trial terms can vary by product and situation, we’ll walk you through the exact steps and requirements at purchase so you know what to expect and feel confident.
