The Mattress Nerd’s Take: The Nest Alexander Signature Cooling topper is a high-quality pick for sleepers looking for a topper with a plush feel that can provide pressure relief for any sleeping position and has active cooling features. It’s also an excellent option for shoppers who are interested in the Nest Alexander Signature Hybrid or Foam mattress but don’t want to invest in a new mattress just yet, and it’s one of our best cooling mattress toppers. This topper is covered in the same active cooling fabric found on the Alexander mattresses and can add noticeable comfort and temperature regulation to your old mattress.

Founded in 2011, Nest Bedding is known for selling a variety of mattresses and bedding accessories online and in showrooms. The Nest Alexander Cooling Mattress Topper echoes many of the features of Nest’s best-selling Signature Hybrid mattress: It’s made with the same phase-change, cooling cover found on the Hybrid and includes 2 inches of Energex foam.

The Energex foam strikes a balance between the feel of memory foam and the feel of a natural latex mattress. It combines responsiveness, cooling for hot sleepers, and relief for pressure points and back pain. Reviewers on write that the topper successfully alleviated areas of aches and pains. In addition, it changed the feel of their existing mattress and helped them sleep cooler. Whether you’re looking to soften a firm mattress or add plushness to a new bed, the Nest Topper is an affordable option to change the feel of your sleeping surface whether you’re a back sleeper, side sleeper or stomach sleeper.

What is the Nest Alexander Cooling Mattress Topper Made Of?

Phase-Change Cover

Nest uses this same cover on all of its Alexander Signature Series products. It’s made with a technology that thermo-regulates the body by absorbing or releasing energy as necessary to keep the body at a healthy temperature throughout the night.

Energex Foam

Energex foam is breathable and pulls heat away from the sleeper. It’s similar to latex because it has a light bounce and a quicker response to pressure. Still, Energex foam features conforming and elastic properties that are similar to what you might experience on a memory foam mattress.

What Does the Nest Alexander Cooling Mattress Topper Feel Like?

The cover of the Nest topper feels cool to the touch and should stay in place easily when the corner straps are attached to the mattress underneath a fitted sheet. The Energex SmartFlow foam interior is a cooling gel memory foam that absorbs body heat and has a plush, soft feel. It’s an excellent choice for side sleepers, lightweight sleepers and people who like soft mattresses. However, back sleepers, stomach sleepers and people who enjoy firmness levels that are Medium or Medium Firm may find it too soft. Unlike a traditional memory foam topper, the Nest will not trap heat and doesn’t have the deep hug of memory foam, although it is still very contouring and pressure-relieving.

The Nerd’s Final Take

The Nest Alexander Cooling Topper has a Soft to Medium Soft firmness setting, making it ideal for side sleepers and lightweight sleepers who want pressure relief. It also works well for average-weight sleepers who are sleeping on a mattress that’s too firm for their taste. However, all sleeper types will rest a little cooler with the addition of this topper. If you’re a heavier-weight sleeper (more than 230 pounds), you’re unlikely to feel a significant change in the comfort of your mattress due to the firmness setting and 2” thickness of this topper, and we recommend looking for a Medium or Medium Firm topper instead.
