# Serta iComfortPro Granby 11.5-Inch Extra Firm Twin XL Latex Foam Mattress

Serta iComfortPro Granby is an 11.5-inch, extra-firm Twin XL mattress built around latex foam. Its five-zone support design and cooling-focused cover are intended for buyers who want a firm, responsive foam surface, while the unusually conflicting listed dimensions make a size check important.

## At a glance

- The listing describes an extra-firm feel and identifies stomach and back sleepers as intended users.
- A five-zone response design is claimed to target support and contouring across the body.
- The listed latex foam and cool-to-the-touch cover are presented as breathable and temperature regulating.
- The manufacturer claims a 100-night trial, a 10-year limited warranty, CertiPUR-US-certified foams, adjustable-base compatibility and delivery not compressed in a box.

## Pros

- Extra-firm construction may suit shoppers who specifically prefer a firmer mattress feel.
- The latex comfort layer is described as responsive, with claimed pressure relief and low motion transfer.
- Five-zone support and a cooling-focused cover offer distinct design features beyond a basic foam mattress.

## Cons

- The extra-firm feel is a poor match for buyers seeking a soft or plush sleep surface.
- At 68.8 pounds, moving or positioning the mattress may take more effort than with a lighter mattress.

## Before you buy

- The listing is contradictory about dimensions: it gives 79.5"L x 39"W x 11.5"Th in one field, 80 x 38 x 12 inches in another, and separately describes the mattress as 11.5 inches thick. Confirm the selected Twin XL product's measurements before ordering. The 100-night trial and 10-year limited warranty are manufacturer claims, and the supplied details do not state their terms.

## In the box

- Mattress (Included)

## A good fit for

- Stomach and back sleepers who prefer an extra-firm feel.
- Twin XL shoppers interested in latex foam, zoned support and a cooling-focused cover.

## Less suited to

- People who want a plush or distinctly soft mattress.
- Buyers who need dimensions confirmed without checking the inconsistent listing measurements.

## Customer feedback

Only a very small set of aggregate ratings is provided, with all reported ratings in the top category. That is encouraging but too limited to establish a dependable pattern about comfort, firmness or durability. For this extra-firm latex model, consider the stated design and check the dimensions rather than treating the ratings as evidence of how it will feel to you.
