Orion Sleep

AI-powered temperature-regulating smart mattress cover

Overview

Orion Sleep develops a personalized smart mattress cover that enhances sleep quality by actively regulating the wearer’s core body temperature. The cover tracks biometric data and uses an AI system to heat or cool the bed through the night, aiming to deepen sleep and improve REM cycles. It offers dual-zone temperature control so two people can set their own preferred temperatures. The product begins with an at-home sleep test using a disposable wearable sensor to map sleep patterns and temperature needs. The business model combines an upfront hardware purchase with a monthly subscription for access to the AI-powered temperature adjustments, pricing a queen-sized cover at $2,300 plus $17 per month. Orion positions itself as a more affordable alternative to high-end temperature sleep systems and targets broad consumer adoption. Its goal is to help more people sleep better and potentially support longevity by optimizing sleep quality through precise temperature management.

Simplify's take

What believers are saying

  • TechCrunch's September 18, 2026 review praised Orion's all-night cooling performance.
  • Orion's website on November 9, 2026 advertised free shipping and a 30-night trial.
  • The company won the 2026 iF Design Award, strengthening consumer credibility.

What critics are saying

  • A queen costs $2,395, limiting adoption outside affluent hot sleepers.
  • Eight Sleep still sells the better-known Pod 6 and forces Orion into price competition.
  • A water leak recall would halt shipments, drain cash, and destroy trust overnight.

What makes Orion Sleep unique

  • Orion sells a retrofit hydronic cover, not a full mattress, starting November 2026.
  • Core heating and cooling works without a required subscription, unlike Eight Sleep Pod 6.
  • Dual-zone control lets partners set separate temperatures on the same bed.

25-year-old founder's vertigo led to AI mattress cover hitting $10M+ revenue in three months

Harry Gestetner, 25, launched Orion, an AI-powered mattress cover that regulates body temperature to optimise sleep quality. The startup surpassed eight-figure revenue within three months of launch and is currently growing 112% month-over-month. Gestetner developed the product after experiencing severe vertigo from overwork whilst building Fanfix, which sold for over $100 million. Working with sleep specialist Dr Michael Breus, he created a smart cover with dual temperature zones that tracks biometrics and adjusts throughout the night. Orion competes with Eight Sleep by offering lower pricing from $2,295, requiring no subscription, and including a personalised sleep test from day one. The product won the Red Dot Award and iF Design Award for 2026. Gestetner plans to expand into hotels within five years.
