The Clark Rubber Comfort Deluxe is a simple foam mattress range aimed at occasional sleeping, but the evidence does not establish how well it performs in use. For the Queen model reviewed by CHOICE, the listing records a claimed firm feel, 10.5 cm thickness and 201.5 × 151 cm footprint. Clark Rubber also sells 100 mm versions in other sizes, whose product descriptions do not all use the same firmness language.
Which Comfort Deluxe mattress does this review cover?
CHOICE’s review titled “Clark Rubber Comfort Deluxe (100mm) review” identifies its test model as a Queen foam mattress. Its public listing gives dimensions of 201.5 × 151 × 10.5 cm and a thickness of 10.5 cm. Clark Rubber uses “100 mm” in the product naming for variants; that name and CHOICE’s 10.5 cm measurement are source-specific specifications, so they should not be treated as identical measurements.

There is no single firmness description that applies consistently across the cited configurations. CHOICE lists the Queen model’s claimed firmness as firm. Clark Rubber describes a single-size Comfort Deluxe listing as medium-soft, while its King Single 100 mm listing describes higher-density foam with a firm feel. Its camp listing describes medium-soft support.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.

- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
These are claimed or retailer-described feels, not a set of independent firmness measurements. If firmness is important, confirm the exact variant and assess its suitability for the person who will use it rather than relying on a range-wide label.
What are its construction and care features?
Clark Rubber describes the range as using Australian-made Dunlop foam and a lightweight microfibre cover that can be removed and washed. The retailer also says the foam has Ultra-Fresh antimicrobial treatment intended to help control dust mites, mould, mildew and fungi, and notes a Sensitive Choice endorsement associated with the National Asthma Council Australia. These are retailer-stated features; the accessible CHOICE material does not independently demonstrate health or allergy outcomes.

Clark Rubber states a one-year warranty. Its product pages refer to a care guide, but the available information does not provide detailed washing or drying instructions. Follow the current instructions supplied with the exact mattress, and check the warranty terms that apply to that variant.

CHOICE lists three layers and an 8 kg weight for the Queen model, in addition to its dimensions and claimed firmness. Its review identifies test areas including support, stability, sagging resistance, breathability, wear resistance and warmth or coolness. The corresponding scores, detailed results and recommendation are members-only on the public page, so they cannot support a numeric rating or a claim that the mattress performs well or poorly on any of those measures.

Customer feedback visible in the cited material is also too limited to settle comfort or durability. The King Single 100 mm result shows one five-star rating and a comment dated 18 June 2026; that is a single anecdote about a different size. The Queen-page result shows one short review dated 15 October 2024 for a 70 mm view, not a basis for judging the 100 mm configuration.
Could it suit a guest bed, caravan or camping?
Clark Rubber describes intended uses across the range that include occasional bedding, guests, sleepovers, caravans and camping, with wording that varies by product. Those are the retailer’s use-case claims, not independent findings that every variant fits every bed or is suitable for frequent nightly use.

Before choosing one for a caravan or guest setup, measure the available sleeping surface and compare it with the exact mattress dimensions and depth. Also consider how often it will be used, how it will be stored, and whether the cover’s care requirements fit the setting. The cited evidence does not establish long-term comfort, support or durability under regular use.
What price did CHOICE show?
CHOICE’s accessed page displayed $425 as the price and $329 as the price paid on sale or after bargaining for its reviewed Queen model. These are figures shown on that page, not a live quote or a current offer. Check the seller’s current price, stock, size and exact variant before ordering; prices for other Comfort Deluxe configurations are not directly comparable with the CHOICE Queen model.

How to judge whether it is the right choice
The available public information is useful for identifying basic specifications and retailer-stated features, but it does not provide the accessible performance results needed for a confident comparative verdict. Compare any mattress you are considering on the points that matter to your use:
Quick Recap
- Fit: Match the exact size and depth to the bed frame, caravan base or intended sleeping area.
- Feel: Separate the retailer’s description from independently measured firmness, and verify the exact variant.
- Frequency: Decide whether it is for occasional guests or regular sleeping; the available evidence does not demonstrate performance over frequent use.
- Care: Confirm the cover is removable on the model you are buying and consult its care instructions.
- Warranty: Read the terms for the exact product rather than relying only on the stated duration.
- Price: Compare current delivered prices for the same size and depth.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
