The Alexa Sleep Customizable Gel Memory Foam Mattress starts with a simple question: how do you like your mattress to feel? Choose gel memory foam for a softer, closer contour, or copper gel memory foam for a slightly firmer surface.
Underneath your choice, a transition layer and high-density support foam core form the shared foundation. You personalize the top layer while the rest of the construction stays consistent. It is an easy way to compare two distinct comfort options without sorting through a long list of mattress models.
On Queen, King and California King, each sleeper can choose a different top layer. Gel on one side and copper gel on the other? That is included in the size price, with no extra charge for copper or split comfort.
Both options belong to the same customizable mattress design. The difference to focus on is the feel at the surface.
Choose gel if you enjoy a more yielding top layer that lets you settle into the surface. It is the softer of these two options and the starting selection in the builder.
When comparing it with your current mattress, think about whether you want a little more give around the areas that press into the bed. This choice focuses on that immediate, cushioning sensation.
Choose copper-infused gel memory foam if you enjoy contouring comfort with a slightly firmer feel than our standard gel option. The transition layer and support core underneath stay the same.
Copper gel is included at every available size. You can compare it directly in the layer illustration without changing the price or rebuilding your selection from the beginning.
Choose by feel. Room temperature, bedding and personal preference also affect sleeping comfort; a material name alone does not tell you how cool a complete bed will feel.
Each part has a different job. The visual builder makes it easy to see which layer you are choosing and which parts remain shared.
Your gel or copper gel memory foam top establishes the first impression of the mattress. Eligible split sizes let you make this choice independently for each sleeper.
Transition foam creates a gradual change between the comfort surface and the support core. It stays continuous across the mattress, including when you choose different top layers.
High-density support foam forms the structural base beneath the comfort system. This shared core supports both sides and keeps the construction simple.
A quilted zippered cover completes the design. The layer illustration updates with your comfort choices; the finished mattress image illustrates the covered gel configuration.
You do not have to agree on the top layer to share a bed. With Split comfort on Queen, King and California King, one person can choose softer gel while the other chooses slightly firmer copper gel.
Select your size, turn on Split comfort, then use the dropdowns directly on the mattress image or the comfort controls. “Your side” and “Partner’s side” keep the choices clear. Check the summary before adding your mattress to the cart.
The lower transition and support layers remain shared. This is a split comfort surface inside one mattress, rather than two separate mattresses for independent adjustable-base movement. Twin, Twin XL and Full use one shared top-layer choice.
If you like a close, cushioning contour and a straightforward choice of surface feel, start here. If you prefer a buoyant response and want to select firmness throughout the mattress, explore our Customizable Talalay Latex Mattress.
With this gel memory foam mattress, your main comfort decision is gel or copper gel. The foundation stays fixed, so you can concentrate on the sensation you want at the top. All available choices are included in the listed size price.
The Talalay model has three 3-inch latex layers, with Soft, Medium or Firm available at each position. Eligible split sizes allow separate choices all the way through the stack. It offers more ways to customize a responsive latex feel.
For either design, describe what you like or dislike about your current bed when you contact our team. Your usual sleep position, desired amount of cushioning and preference for a softer or firmer surface are useful starting points. You can also save a build for each mattress in this browser while you compare.
