Helix Midnight Luxe

Sources & review notes

• Exact model — Helix Midnight Luxe — TENCEL cover, standard Luxe Layer. Checked 2026-10-20. The Luxe-collection version of the Midnight, sold as one medium feel. The same listing sells three paid add-ons that change the build: a GlacioTex cooling cover (+$187 at check), GlacioTex plus a CoolForce heat-transfer layer (+$374), and an ErgoAlign extra-firm hip segment (+$187). Every fact and measurement here is for the base configuration unless stated. This is not the 11.5-inch Core Midnight, the 15-inch Midnight Elite, or the higher-weight Helix Plus.
• Type — Zoned-coil pillow-top memory-foam hybrid. Checked 2026-10-20. Helix lists, top to bottom: TENCEL cover, gel memory foam, a SupremeSupport 4.0 memory-foam layer it states is 4 lb density, a medium Premium Responsive Foam layer, up to 1,000 individually wrapped coils with reinforced support under the hips and around the full perimeter, and a DuraDense foam base. Foams are CertiPUR-US certified and the mattress is assembled in Arizona.
• Firmness — Medium (manufacturer) — 6/10 measured. Checked 2026-10-20. Helix calls it a "Medium Feel" and positions it for side sleepers. NapLab measured 6 of 10 on its September 2026 unit and Mattress Clarity also landed on 6. There is no soft or firm version of the Midnight Luxe; the Sunset Luxe and Dusk Luxe are the softer and firmer siblings.
• Height — 13.5 inches (queen: 60 × 80 × 13.5 in). Checked 2026-10-20. Helix publishes 13.5 inches for the whole Luxe collection, two inches above the 11.5-inch Core Midnight. NapLab recorded its test unit at 14 inches, a half-inch variance we attribute to a quilted pillow-top measured under no load rather than to a different version.
• Price — Check current price — $1,999 queen with code, $2,498.75 list. Checked 2026-10-20. Recorded on the checked date with a 20%-off site code applied to the base TENCEL build; in September 2026 a 25%-off code produced $1,874 against the same list. Add-ons stack on top of the base price, so a fully optioned queen costs materially more.
• Trial — 365-night sleep trial, 30-night minimum. Checked 2026-10-20. Helix extended its trial from 120 to 365 nights by the October 2026 check. Keep the mattress at least 30 nights; after that an exchange of equal or greater value or a full refund is available through night 365. The trial applies only to orders placed directly on helixsleep.com.
• Delivery — Free FedEx Ground, ships in 5–8 business days. Checked 2026-10-20. Compressed and boxed (about 47 × 16 × 16 in) from Helix’s Phoenix facility. An "In-Home Setup & Removal by Ryder" option, covering setup, old-mattress removal, and packaging removal, is selectable at checkout in the contiguous US; the product page shows it as ZIP-dependent and did not display a price on the checked date.
• Returns — Full refund or exchange, nights 31–365, mattress collected. Checked 2026-10-20. Helix states the mattress is removed from your room and you do no heavy lifting. Refunds follow once the mattress is confirmed received.
• Warranty — Limited lifetime — 10 years non-prorated, then prorated. Checked 2026-10-20. For mattresses bought after 1 February 2025. Years 1–10 are repair or replace at no cost; years 11–15 cost 50% of the then-current retail price, 16–20 cost 60%, and 21 onward cost 75%. A visible indentation must exceed 1.5 inches to qualify, slats wider than 5.5 inches apart void it, and removing the cover voids a claim. Earlier-generation Helix warranties used a different term, so third-party reviews citing 15 years or a 1-inch threshold describe the old policy.
• Firmness — Medium (6/10). Measured data. Matches Helix’s "Medium Feel" label. The Luxe does not feel softer than the Core Midnight so much as deeper: the extra height is in the comfort stack, not in a plusher surface.
• Pressure relief — 2.03 in initial sinkage. Measured data. A moderate contour. The 4 lb memory-foam layer cradles the shoulder without the deep hug of a softer all-foam bed, which is what keeps the hips from following the shoulder down.
• Cooling — 89.3 °F peak surface temperature. Measured data. Average for a memory-foam hybrid and the reason the GlacioTex upgrade exists. NapLab’s unit shipped with the cooling cover, so the base TENCEL build may run warmer still; treat this as an upper bound on the cover’s benefit, not a floor.
• Motion isolation — 5.76 m/s² acceleration — 34% below NapLab average. Measured data. Good for a coil bed. Dense memory foam above individually wrapped coils absorbs most of a partner’s movement; Mattress Clarity scored the same trait 4 of 5.
• Response / bounce — 0.4 s mostly recovered, 1.2 s full recovery. Measured data. The trade-off for the motion result. Position changes are unhurried rather than sluggish; the coil layer gives some lift, but the memory foam above it sets the pace.
• Edge support — 2.75 in seated compression. Measured data. A strong result, and the clearest structural gain over the Core Midnight. Helix reinforces the full coil perimeter, and Mattress Clarity independently scored edge support 4.8 of 5.
• Noise — Minimal — top score in NapLab’s noise category. Measured data. Individually wrapped coils under a thick foam stack; no squeak or spring noise was reported when new. Coil noise, if any, tends to appear with age, so this is a day-zero result.
