Very comfortable. Not too soft nor too firm. I haven't gotten up sore from sleeping on the mattress. Feels like it mold in my body. If that makes sense.

Mattress FAQs

Why are the mattresses called Serta Mattress-in-a-Box?

These mattresses are shipped directly to your door in our smallest carton ever, making for the simplest, most convenient arrival and set-up!

Is White Glove delivery available for Serta Mattress-in-a-Box?

White Glove service is not available for EZ Totes at this time. All EZ Totes are shipped via FedEx, who will deliver the carton to your door within 5-14 business days.

Are there any coils in this product?

No, the EZ Totes do not contain any coils. They are all-foam mattresses made up of 2 layers (Sheer Slumber) or 3 layers (Sheep Retreat).

How long can the boxed mattresses stay boxed?

We suggest that the mattress be unboxed within 3-4 weeks. Leaving the mattress in the box longer than that will not harm the mattress, but it may cause the expansion time to take a bit longer.

We do not recommend keeping the mattress boxed for longer than 12 weeks as that can potentially cause the mattress to not fully expand to its intended dimensions.
