The Siena Memory Foam Mattress proves that you get what you pay for. $399 for a Queen will get you solid support and optimal motion isolation, but it's not enough to afford proper edge support or cooling systems.
Siena falls under Resident Home, the sleep portfolio that also includes Nectar and DreamCloud. These beds are already budget-friendly, but Siena slashes prices still further. You'll never have to pay more than $1,000 for a Siena mattress, even for a California King.
