    Assembly

    Bigg+ Mattress assembly

    Assembling the Bigg+ Mattress usually takes around 20–30 minutes. Here are the steps to follow:

    1. Illustration showing person placing Turmerry mattress cover on bed frame in bedroom with potted plant and dog nearby.

      Open up all of the boxes, take out the zippered mattress cover first, and lay it on your bed frame.

    2. Illustration showing person placing perforated Turmerry Bigg+ latex layer, labeled Extra Firm, on the bed.

      Identify the base layer of your mattress (Extra Firm) and place it into the cover first.

    3. Illustration showing person stacking two more extra firm Turmerry Bigg+ latex layers on top of initial extra firm layer.

      Identify the two middle layers (both Extra Firm) and place them atop the base layer.

    4. Illustration showing person layering medium, firm, or extra firm Turmerry latex layer on top of three extra firm layers.

      Place the final layer (Medium / Firm / Extra Firm) at the top and close the zippered cover.

    Care

    Bigg+ Mattress care

    Taking care of your Bigg+ Mattress on a regular basis can ensure that it lasts longer, is hygienic, and is always comfortable to sleep on. Following these tips is recommended:

    Bed frame guidelines

    For slatted bed frames, always ensure the space between the slats should be no more than 3 inches apart. If your current bed frame has slats that are spaced more than 3 inches apart, we recommend adding extra slats in between the existing ones or placing a simple Bunkie board/plywood sheet over your current frame.

    Note: Improper slat spacing may void the warranty.

    To enhance longevity

    Use a waterproof mattress cover over your mattress. Once a month, air out the mattress for a few hours. Every few weeks, vacuum the dust, dirt, crumbs, and other particles away from the top of the mattress. Rotate the mattress head to toe once a month for the first 6 months, then every 3–6 months. Flipping it isn't necessary or recommended.

    Liquid spills should be spot-cleaned

    Blot up as much of the spill as you can with a clean cloth. Dab the spot with a cloth dampened with cool or lukewarm water and a little mild detergent; don't soak it. Blot with a clean, damp cloth to rinse, then let it air dry completely before you make the bed again. If liquid soaks through, unzip the cover and check the latex layers.

    Avoid these things

    Avoid drying the organic latex foam under direct sunlight. Avoid using hydrogen peroxide and other harsh chemicals/detergents. Avoid using the mattress before it is completely dry. Avoid hand washing or machine washing any of the foam layers and the mattress cover. They should not be placed in a dryer, either.

    Bigg+ Natural Latex Mattress for Heavy People FAQS:

    Is the Bigg+ Mattress specifically designed to support heavier body weights?

    Yes, the Bigg+ Mattress is specifically designed with high-density Dunlop latex to support heavier body weights above 230 lbs. It's estimated to support up to 1,100 lbs total weight in King and Cal King Extra-Firm (see the weight limits by size below). It features three extra-firm 3-inch layers for the support core and one medium/firm/extra firm 3-inch layer for the comfort layer, providing robust support and comfort for bigger sleepers.

    Do heavier people need a firmer mattress?

    Usually, yes. Heavier sleepers press deeper into a mattress, so a soft one can feel like sinking. Every Bigg+ model has three extra-firm 3-inch support layers, and you choose the 3-inch top layer:

    • Medium for the most cushioning (mainly side sleepers around 230 lbs)
    • Firm, a balance of cushioning and support that suits most heavy sleepers
    • Extra-Firm for the most support, recommended around 280 lbs and over

    What is the best mattress for a 300, 400 or 500 lb person?

    Check the total weight on the mattress against our capacity table (all sleepers combined):

    • One sleeper around 300 lbs fits every Bigg+ size and firmness.
    • A 400 lb sleeper fits a Queen or larger, or a Twin XL in Firm or Extra-Firm.
    • A 500 lb sleeper fits a Queen or larger, or a Twin XL in Extra-Firm.
    • The highest estimated capacity is 1,100 lbs total on the Extra-Firm King and Cal King.

    These capacities are estimates based on material specifications. Use a sturdy foundation.

    What's the best Bigg+ firmness for heavy side sleepers?

    Firm suits most heavy side sleepers: it gives some give at the shoulders and hips without letting you sink too far. If you're around 230 to 280 lbs and want more cushioning, Medium is an option. Heavy back and stomach sleepers usually do best on Firm or Extra-Firm, which keep the hips from sinking, and we recommend Extra-Firm if you weigh around 280 lbs or more. Not sure? Take our 1-minute mattress quiz.

    Is the Bigg+ a good mattress for heavy couples?

    Yes. Pick the size and firmness by your combined weight:

    • A Queen holds up to 650-850 lbs total, depending on firmness.
    • A King or Cal King holds up to 850-1,100 lbs total.

    The all-latex build is responsive, so it's easy to change position, and the firm layers give a stable edge for sitting.

    How does the Bigg+ Mattress prevent sagging over time for heavier sleepers?

    High-density Dunlop latex is highly resistant to sagging because of its dense cell structure and high compression resistance. Unlike polyurethane foam, which relies on synthetic fillers and breaks down faster, Dunlop latex is made through a process that retains more rubber content, making it firmer and more durable. This results in a higher material density per cubic inch, meaning it can withstand continuous pressure without losing its shape.

    Additionally, Dunlop latex has a more supportive and less airy composition than Talalay latex, which makes it better suited for heavier sleepers who need long-term stability without deep body impressions.

    The combination of three extra-firm and one medium/firm/extra-firm layer also plays a part, as this layered construction ensures proper weight distribution, reducing the risk of premature sagging. Finally, the cherry on top is the mattress’s certified, high-quality materials, which ensure it does its job and doesn't fail to perform like cheaper, low-quality mattresses.

    What type of foundation or bed frame is best for supporting the Bigg+ Mattress and a heavier sleeper?

    To maximize the support and lifespan of our Bigg+ Mattress, we recommend using a solid wood or metal bed frame, such as a natural wood slatted bed frame or a metal adjustable bed base. These options will provide the necessary support for both the mattress and the sleeper. Make sure to check the weight limit of your desired bed frame and confirm it will be able to hold the combined weight of the sleeper(s) and the mattress.

    Note: - We do not recommend a box frame, as it may impact the mattress's feel. A solid bed frame or foundation is ideal.

    Does the Bigg+ Mattress have a recommended total weight limit?

    The recommended total weight limit for the Medium Bigg+ Mattress (3 Extra Firm layers + 1 Medium layer) is as follows -

    • Twin XL (38" x 80") | Medium = 400 lbs.
    • Queen (60" x 80") | Medium = 650 lbs.
    • King (76" x 80") | Medium = 850 lbs.
    • California King (72" x 84") | Medium = 850 lbs.

    The recommended total weight limit for the Firm Bigg+ Mattress (3 Extra Firm layers + 1 Firm layer) is as follows -

    • Twin XL (38" x 80") | Firm = 450 lbs.
    • Queen (60" x 80") | Firm = 750 lbs.
    • King (76" x 80") | Firm = 950 lbs.
    • California King (72" x 84") | Firm = 950 lbs.

    The recommended total weight limit for the Extra-Firm Bigg+ Mattress (All Extra Firm layers) is as follows -

    • Twin XL (38" x 80") | Extra-Firm = 500 lbs.
    • Queen (60" x 80") | Extra-Firm = 850 lbs.
    • King (76" x 80") | Extra-Firm = 1,100 lbs.
    • California King (72" x 84") | Extra-Firm = 1,100 lbs.

    Total Weight Limit Note:

    Our Bigg+ Mattress is designed with high-density natural latex and durable construction, estimated to support up to 1,100 lbs total weight (not per sleeper) when used with a sturdy foundation. This is an informed estimate based on material specifications; formal weight capacity testing has not been conducted. For best results, ensure even weight distribution and use a solid, supportive bed base.

    Which Bigg+ Mattress size is right for me?

    • Twin Mattress

    A twin mattress is the smallest standard mattress size in the US and measures 38" by 75". It's the best option for growing children or young adults.

    The average room size recommended for a twin latex mattress is 7 feet by 10 feet. This means twin mattresses are ideal for smaller bedrooms, bunk beds, etc.

    • Twin XL Mattress

    A twin XL mattress is 5 inches longer than the standard twin mattress and measures 38” by 80”. It's the best choice for teens, single adults, or taller individuals.

    The average room size recommended for a twin XL latex mattress is 8 feet by 10 feet, making them ideal for college dorm rooms or anywhere else with limited space.

    • Full-Size Mattress

    Also known as a double mattress, a full-size mattress measures 54" by 75" and is best suited for single sleepers. It's recommended for solo adult sleepers who need more space than a twin or twin XL.

    A full-size latex mattress fits into almost any room without making it look crowded. However, the minimum recommended room size for a full bed is 9 feet 6 inches by 10 feet 6 inches.

    • Queen Mattress

    Queen-size mattresses are the most popular mattress sizes in the US, measuring 60" by 80". They are one of the best options for couples, single parents who share the bed with their child, or single sleepers who prefer a lot of space to sprawl out. These mattresses are also a great option for pet parents who share their beds with furry friends.

    The recommended room size for a queen-size latex mattress is 10 feet by 10 feet.

    • King Mattress

    Measuring 76” by 80”, sleeping on a king-size mattress is a luxurious experience. They are the widest standard mattress size available and are best suited for couples who prefer extra space to sprawl out.

    The recommended room size for a king mattress is 12 feet by 12 feet.

    • California King Mattress

    Four inches longer and four inches narrower than a king-size mattress, a California king mattress can accommodate two tall adult sleepers comfortably, along with an extra (smaller) sleeper. These mattresses measure 72" by 84" and are great for sleepers who are 6 feet or taller.

    The minimum recommended room size for a California king latex mattress is 12 feet by 12 feet.

    What is latex, and why do mattresses use natural latex?

    Latex is a natural product found beneath the bark of mature rubber trees. The milky white liquid that seeps from the rubber tree is collected and then processed to create either natural Talalay latex foam (softer) or natural Dunlop latex foam (firmer). Natural latex foam has a number of unique properties that make it ideal for use in mattress construction, including responsiveness, bounce, durability, breathability, resilience, and a willingness to conform to the body's contours.

    Is a latex mattress better than a memory foam mattress for heavyweight sleepers?

    Yes, a latex mattress is generally better suited for heavyweight sleepers compared to memory foam. Latex provides more responsive support, which helps distribute body weight more evenly and prevents the feeling of sinking too deeply into the mattress. This is especially important for heavier sleepers, as latex maintains its shape and support over time, offering better durability than most memory foam options.

    Another major advantage of a latex mattress is its ability to allow unrestricted airflow through it, resulting in breathable cooling on the mattress surface. Memory foam mattresses often lack this, as they are dense and absorb body heat to conform to the sleeper, which in turn makes the mattress surface hotter.

    Do Turmerry latex mattresses contain chemicals?

    We can proudly say that our organic latex mattresses are made without synthetic foam or chemical fire retardants. We produce latex to the highest possible organic standard (≥95%), and it has been certified by the Global Organic Latex Standard (GOLS), OEKO-TEX Standard 100, eco-INSTITUT, FSC, and LGA, ensuring a healthy bedroom environment!

    What is the general adjustment period for a latex mattress?

    Just like any other major change in your life, it takes time for your body to adjust to sleeping on a new mattress. Depending on the person, it can take anywhere from just a single night to a week to get used to sleeping on a latex mattress. From the feedback we've received, most customers adapt to it the first night itself.

    How long do latex mattresses last?

    Latex mattresses are known for their durability and long lifespan. In fact, many latex mattresses come with a long warranty. While other types of mattresses start to show signs of wear and tear after just a few years, latex mattresses can last 15-20 years or more with proper care. This is due to the high-quality materials used in construction and the unique resilience of latex.

    Does the mattress smell of latex or wool?

    Most customers set it up and sleep on it the first night. Fresh latex can have a faint, sweet scent when first unpacked, and our wool has no barnyard smell.

    If you're very sensitive to smells, leave it in an airy room for a day or two before making the bed.

    Warranty and returns

    The Bigg+ Mattress comes with a 20-year warranty that starts on the date of purchase. Furthermore, we provide a 120 Night Trial.

    We believe trying a mattress for just a few minutes at a local store isn't enough. You need to know how it feels for at least a month before you spend a third of your life on it.

    1. Sleep on it for at least 30 nights. We insist that you try it for at least 30 nights before initiating a return.
    2. Firmness not right? Any time during your 120-night trial, you may request one free comfort layer in a different firmness (you keep the original, with nothing to send back). Still not happy? After the first 30 nights, you may request a return within 120 nights of the delivery date. Read more about our return process.
    3. Contact us before you donate. During a return, we will ask you to follow a local donation procedure to reduce greenhouse gas emissions associated with further shipping. We have a simple process for this, so please make sure to contact us for instructions; afterward, you can begin your return here.
    4. Important: the cover comes back first. Before donation, the mattress cover must be returned to us, free of stains, damage, or signs of misuse. Only after it has been inspected and approved by us can a refund be issued.

    Good to know

    • If you try a new comfort layer and still find our all-latex mattress unsatisfactory afterward, you can still return the mattress within 120 nights.
    • If you choose to return your mattress before 30 nights, cancel an order after it has shipped, or refuse delivery, we will be issuing store credit instead of a refund.
    • Our policy only allows for the return or exchange of one item per product type (e.g., mattress topper, sheet set) per household within a 12-month period, with the exception of pillows, where up to two can be returned.
    • Mattresses have a stricter limit: each household can return or exchange one mattress in total. We count a household as orders that share a customer name, shipping address, billing address or payment method.
