Off-gassing occurs when volatile organic compounds (VOCs) are released from foam and other materials. The process emits odors ranging from mild to very prominent. While the tiny molecules aren’t considered harmful, some people are more sensitive to the smell than others.
We found that both versions of the Lytton Signature had a slight off-gassing odor when first unboxed, but nothing too pungent. Once the mattress is unpacked, odors should dissipate within 48 hours.

Launched in 2019, Lytton Sleep is a relative newcomer in the online mattress space that prides itself on transparent sourcing of materials. While the company’s fabrics are manufactured in Canada, all other components are U.S.-sourced and the mattresses are handcrafted by Michigan-based manufacturer Capitol Bedding.
The company has one mattress model at this time: the Lytton Signature. The hybrid has a 13-inch profile and comes in two feels: Comfort Plush and Comfort Firm, which equate to medium (5) and firm (7) on our 10-point firmness scale. The Signature is available exclusively through the company’s website.
We’ll cover all the specifics of the Lytton Signature, including its materials, construction method, warranty, and shipping policies. We’ll also compare the feel and performance of the two firmness options so you can decide which is the more appropriate fit.
The Lytton Signature comes in two firmness options: Comfort Plush and Comfort Firm. The former has a medium (5) feel, while the latter is firm (7).
- Choose Comfort Plush if…
you’re a side sleeper who weighs less than 230 pounds. A plush Euro-top and Serene Foam comfort layer cushion sensitive pressure points on the hips and shoulders. The medium feel also promotes neutral spine alignment for back and stomach sleepers up to 130 pounds. - Choose Comfort Firm if…
you prefer a sturdier surface that moderately contours the body. The firm and responsive layers resist compression, so sleepers stay more on top of the mattress. This makes changing positions easier while also minimizing uncomfortable heat buildup. While the Comfort Firm suits all sleep positions, the firm feel is an especially good fit for stomach and back sleepers over 130 pounds.

Side Sleepers
With its cushy Euro-top and cradling foams, the Signature performs well for most side sleepers. The thick comfort system eases pressure points on the hips and shoulders while evenly distributing body weight.
Side sleepers between 130 and 230 pounds should experience comparable pressure relief with either firmness option. We found the Comfort Plush model to be a better choice for side sleepers under 130 pounds, as they require more cushioning to alleviate tension, while those over 230 pounds receive better support from the Comfort Firm version.
Back Sleepers
Our testers found the Comfort Firm to be an excellent choice for back sleepers in any weight range. The sturdy pocketed coil core resists sagging beneath the torso, while the plush Euro-top cushions the shoulders and legs. Back sleepers over 130 pounds should be especially comfortable on the Firm model, as they only need mild contouring.
Performance is more mixed for back sleepers on the Comfort Plush. Since sleepers under 130 pounds don’t sink as much, the medium feel is firm enough to support neutral spine alignment. However, back sleepers on our testing team weighing more than 130 pounds reported less sagging and better support on the Comfort Firm model.
Stomach Sleepers
Stomach sleepers usually need a firm mattress to keep the midsection from sinking excessively. A mattress that is too soft or conforming can place strain on the lower back.
Similar to back sleepers, the Comfort Firm resists sagging beneath the torso and accommodates stomach sleepers across all weight categories. Stomach sleepers under 130 pounds should also feel supported on the Comfort Plush, though deep sinkage on the softer option is more likely for those over 130 pounds.

Lytton Signature Review Breakdown
The Lytton Signature is a hybrid mattress that comes in two firmness options: Comfort Plush and Comfort Firm. The former has a medium (5) feel, while the latter rates as a 7 on our 10-point firmness scale. Both models are 13 inches thick and feature the same essential materials and layout, though differing foam densities account for the firmness variations.
A plush Euro-top is covered in soft and breathable organic cotton with a thin underlayer of polyester. Quilted inside is a 1-inch layer of gel-infused polyfoam. The foam’s open-cell construction and cooling gel infusions are designed to draw out excess heat, helping the surface stay more temperature neutral.
Next is a layer of contouring yet responsive Serene Foam that helps spread body weight evenly across the mattress. Made by Virginia-based Carpenter Co., the proprietary foam is formulated with microscopic air capsules designed to increase breathability. Testing indicates that Serene Foam offers comparable pressure relief to memory foam but is more responsive and durable.
The Comfort Firm model has an indentation load deflection (ILD) rating of 22, showing that it resists compression well under weight and pressure. A 12 ILD on the Comfort Plush reflects a softer comfort system that more closely conforms to sleepers.
Both versions feature an 8-inch pocketed coil core to reinforce the comfort layers. Additional coils beneath the hips and shoulders are designed to promote good sleep posture. Each spring is individually wrapped to move independently, allowing the core to adapt to each sleeper’s movements. The design also helps reduce motion transfer while promoting more airflow than traditional coil systems.
A 1-inch base layer of high-density polyfoam stabilizes the mattress. The final layer also functions as a fire barrier, thanks to flame-resistant fibers.
CertiPUR-US certification shows that the foams are manufactured without harmful chemicals. Queen and larger sizes have eight handles on the sides to make carrying the mattress easier.

Availability
The Lytton Signature is available in all 50 states and is sold exclusively through the company's website.
Shipping
The Signature ships free of charge to the contiguous U.S. via FedEx or a similar courier service. Orders shipped to Alaska or Hawaii incur a freight fee.
Each mattress is made to order, so shipping times may vary. The mattress is compressed, sealed in plastic, and shipped in a box. The company recommends waiting at least 24 hours after unboxing to sleep on it, as it can take up to 48 hours for the mattress to fully expand.
Additional Services
Lytton Sleep currently does not offer White Glove delivery or old mattress removal.
Sleep Trial
The Lytton Signature includes a 100-night sleep trial. The company asks that customers keep the mattress for at least 30 days before initiating a return. Mattresses returned during the trial period are eligible for a full refund. Lytton covers the cost of return shipping for customers in the contiguous U.S.
Warranty
Lytton backs the Signature with a 20-year warranty. The warranty covers manufacturing defects like splits or cracks and surface impressions greater than 2 inches. The softening of foam over time and other typical signs of wear are not covered. Defects caused by neglect, willful abuse, or an improper foundation are also excluded from coverage.
Mattresses deemed defective by Lytton will either be repaired or replaced at no cost to the consumer. Customers should retain their proof of purchase, as the warranty is only valid for the original owner. Other terms and conditions apply.
