Acesleep Mattress Review

Acesleep is an online-only cooling mattress brand run by JLM International LLC. It sells one 12-inch cooling gel memory foam mattress in six sizes, from about $336 to $960 with coupon Ace15. You get a 120-night trial, a 20-year limited warranty and free shipping. It suits budget hot sleepers who want medium-soft all-foam comfort. The catch is that there are almost no independent reviews, and the certification claims are unverified.

Side sleepers are the brand's target, with medium-soft contouring and pressure relief. Back sleepers will likely find it acceptable, but no zoned support is published. Stomach sleepers will likely find it too soft, since there's no firm option.

Heavier sleepers get no plus-size reinforcement, so it's a poor fit. Hot sleepers are steered here with a cool-touch cover and gel foams, though no independent cooling tests exist. Combination sleepers get all-foam motion isolation, but the brand doesn't publish responsiveness data (checked September 2026).

Observed list prices ran from $336.25 for a Twin to $959.99 for a Cal King, with Queen at $889.99. Coupon Ace15 is advertised as saving 15% versus Amazon. Klarna financing starts around $43 a month for a Twin and $77 a month for a Cal King, with 0% APR options per the terms.

This is budget bed-in-a-box pricing, in line with Zinus and Lucid. It's fair value if street prices hold. We found no price-match policy, and the brand doesn't publish sale-versus-list history (checked September 2026).

From the top, you get a removable, washable cool-touch cover in an ice-silk style, with a claimed Q-max of 0.33. Next comes a vest-type flame barrier that's claimed to be free of glass fiber and added chemicals. Then there's 2.5 inches of open-cell gel memory foam, 2 inches of bamboo-charcoal memory foam, a 1.5-inch gel-bead memory foam cushion and a 6-inch dense support core. The total is 12 inches.

The brand claims CertiPUR-US foams, an OEKO-TEX cover and CFR 1633 flammability compliance. It doesn't publish certificate numbers or database listings (checked September 2026). It makes no GOTS, GOLS, GREENGUARD or USDA Organic claims.

The brand reports a 20-year limited warranty against manufacturing defects. It doesn't publish a sag-depth threshold, a prorating schedule, exclusions or claim steps in a full warranty document (checked September 2026). We found no independent durability or lab tests.

The brand claims an anti-deformation support core, but nothing backs that up. The heavy weights suggest dense foams. A Queen weighs 89.9 lbs and a Cal King 114.4 lbs. The brand doesn't publish the densities.

The brand's own reviews page shows 4.8 out of 5 across 211 shopper evaluations. Shoppers praise cool, comfortable sleep and a supportive but cushy medium feel. They also like the motion dampening, the breathable cover and the value.

Complaints include a heavy rolled package that's hard to move and weak edge support. Firmness splits, with some finding it too soft and others too firm at first. Expansion can take hours to days, so you may wait before it feels right. The brand doesn't publish Amazon, Google, BBB, Trustpilot, Sleep Foundation or RTINGS ratings (checked September 2026).

You can buy online direct at acesleeps.com, with cart checkout and account login. The site advertises an Amazon presence, with a Save 15% versus Amazon line and a Buy Amazon link. We found no active Amazon storefront items (checked September 2026).

The brand doesn't publish a dealer network, showrooms, phone ordering or try-in-store locations. Support is at support@acesleeps.com or 571-343-6005. Stated hours are 7 days a week, 6am to 9pm PST.

Shipping is free by UPS and FedEx, typically 3 to 5 business days, with emailed tracking. The bed ships rolled in a box. A Cal King box measures 14.5 x 15 x 72 inches. It fits a box spring, platform, adjustable base, slats, bunk, trundle or the floor, per the brand.

The brand doesn't publish white-glove setup, scheduled delivery windows or old-mattress removal (checked September 2026). Returns are picked up by a local charity or recycling partner.

You get a 120-night in-home trial from arrival, with free return and a full refund. Contact support@acesleeps.com or 571-343-6005 to arrange pickup through a local charity or recycling partner. You don't need to squeeze it back into the box, so you can skip that chore. The brand states no return or restocking fees.

Amazon orders go back through the Amazon portal within Amazon's 30-day window, then through Acesleep within the 120 days. The brand doesn't publish a direct exchange process or refund timing (checked September 2026).

The homepage and product pages describe a 20-year limited warranty covering production flaws. The brand doesn't publish full terms, the minimum sag depth, exclusions, a prorated or full-replacement schedule, claim steps or claim shipping costs (checked September 2026).

You should keep your proof of purchase and use a suitable foundation. You'd contact support@acesleeps.com to file a claim. The brand doesn't publish warranty registration details.
