Tom’s Guide reported a 15% discount on the Lucid 4-inch Gel Memory Foam Mattress Topper on October 2, 2026, describing it as a budget pick for side sleepers who want more cushioning on a firm bed. The prices below are that dated snapshot—not confirmed live prices. Tom’s Guide also reported the topper was sold out on Lucid’s website at publication and directed readers to Amazon, so check the retailer’s current price and stock before buying.
What the deal was—and whether it is still available
Tom’s Guide called the promotion an early Prime Day deal. TechRadar reported that Amazon’s October Prime Day event was scheduled for October 6–7, 2026. As of October 4, the event was upcoming, but the deal’s availability through or after those dates is not established.
Tom’s Guide’s October 2 report listed these Lucid prices:

Why Tom’s Guide recommended it for side sleepers
Tom’s Guide says its testers found that the 4-inch version cushioned the shoulders and hips when sleeping on the side. The article presents it as a way to soften an uncomfortably firm mattress, and says the 4-inch height was tested for more cushioning than the 2-inch and 3-inch versions. That is a report of the publication’s testing, not a guarantee that every sleeper will feel the same effect or a claim of medical pain relief.
Cooling: gel and ventilation, but not a specialist model
The topper is described as gel-infused and ventilated. Tom’s Guide reported that those features helped its testers sleep cool, while also noting that this is not a specialist cooling topper. If strong cooling performance is your main requirement, the cited testing does not establish that this model is the best fit.

A cheaper alternative Tom’s Guide named
Tom’s Guide also listed the Linenspa 3-inch Gel Memory Foam Mattress Topper at lower prices in its October 2 snapshot. The figures support a price comparison only; that article does not establish that Linenspa provides equivalent shoulder-and-hip cushioning or side-sleeper performance.
| Model and size | Reported deal price | Reported previous price |
|---|---|---|
| Linenspa 3-inch, Twin XL | $47.99 | $59.99 |
| Linenspa 3-inch, Queen | $69.99 | $89.99 |
Those Linenspa prices, like the Lucid figures, were reported by Tom’s Guide on October 2, 2026, and may have changed. Compare current prices alongside thickness, current stock, return terms, and warranty details; those last two terms are not established by the cited deal report.
