How can the same mattress cost less here?
The honest difference
Blissful Nights offers an in-home sleep trial. We don't. Our sales are final, and leaving out the cost of returns is a big part of why our prices are this low. If you're not sure which feel is right for you, text John before you order and he'll help you pick. You can also take our 60-second mattress quiz.
Questions people ask us
- Is this really the same mattress as the one on Blissful Nights?
- Yes, for the products on this page. They are the same South Bay International models: the mattresses carry the same model numbers, and the e3 and e4 bases are the same South Bay bases (SBKD3 and SBKDP2). If you're looking at something on Blissful Nights that isn't listed here, text John the link and he'll tell you if we carry it and what it costs.
- What is the ActiveAlign copper mattress?
- It's South Bay's copper-infused memory foam and latex line. It comes in a 10" (Medium-Firm), a 12" zoned (Medium) and a 14" zoned hybrid with pocket coils (Plush). The zoned copper gel guide explains how the zoning works.
- How does shipping work?
- Free FedEx shipping anywhere in the US. Mattresses arrive compressed in a box. We send you tracking as soon as it ships.
- Can you match a price I found somewhere else?
- Text John. We'll always give you a straight answer.
