ChiXpace Memory Foam Mattress Topper, King

For King-size bed owners who want to add cushioning without replacing their mattress, this ChiXpace topper combines a 2-inch gel-infused memory foam layer with a 2-inch quilted pillow top. The egg-crate foam is designed to contour to the body and distribute weight, while the soft upper layer adds a different feel from a single slab of foam. It makes sense if your current mattress could use extra padding and you want a removable cover. It might not be a great match if you want a thinner, simpler pad or need a firm replacement mattress.

Key specifications

This is a King-size topper measuring 78" x 80", with 4 inches of combined layers. The lower layer is gel-infused memory foam with an egg-crate pattern and 7-zone design, the upper layer is a quilted pillow top filled with down-alternative fiber. The product description presents the foam as cushioning that molds to your shape and helps distribute weight. That is a comfort-focused design, not a stated change to the support or condition of the mattress underneath.

The cover is described as skin-friendly, removable, and machine washable, with tumble drying on low. That gives you a practical way to freshen the top layer after regular use. The listing also describes the fabric and gel-infused foam as breathable and cooling, but it does not provide a temperature rating or other measured cooling result. Without having tried it, the most grounded way to assess that feature is as a design aim rather than a guaranteed sleep-temperature change.

Who it’s for

This setup is aimed at sleepers who want a more cushioned surface on a King bed and prefer the feel of layered padding over a basic, single-layer mattress pad. Picture settling onto a bed that feels a little too firm at the shoulders or hips: the egg-crate foam is intended to add contouring, while the quilted top supplies a softer contact layer. The description also says it is designed to avoid noise or movement, though it gives no test results or details about how it performs with different sleepers.

There is a trade-off in choosing a 4-inch, two-part topper: it adds noticeable thickness to the bed rather than making a subtle change. If you mainly need a washable surface layer, a thinner pad may be a simpler fit. And if the mattress itself needs replacing, extra cushioning is not the same as a new support system.

Everyday use

The topper arrives compressed, so it may look thinner immediately after unpacking. The instructions say to allow 24–48 hours for it to expand and regain its shape, gently patting it may help the rebound process. A slight new-foam smell may also be present at first and is said to dissipate over time, so it may be worth airing the room before expecting an immediate, ready-to-use setup.

For upkeep, the removable cover can be machine washed and tumble dried on low. The supplied information does not specify care instructions for the foam layer itself, so the washable-cover detail should not be taken to mean the entire topper can go in the washer or dryer.

Before you decide

How thick is the topper? It combines a 2-inch memory foam layer and a 2-inch quilted top, for 4 inches overall.

How long should it expand after unpacking? The instructions allow 24–48 hours for it to return to its original shape. A slight foam odor may fade over time.

Can you wash the cover? Yes. The cover is removable and machine washable, with tumble drying on low specified. The listing does not give washing instructions for the foam.

Should you buy it?

Choose this topper if you have a King bed and want a substantial layer of cushioning, a contoured egg-crate foam design, and a removable washable cover. Its two-layer construction is more involved than a basic pad, but that also means more added thickness and a short wait for expansion after unpacking. Skip it if you are looking for a thin cover, a replacement mattress, or a firmly specified support change, those needs are not established by the product details.
