Problem 1: Joint looseness (increased looseness)
Causes: long-term large-angle positioning, wear of bolt joint gaskets, damping aging.
Handling:
- Minor loose gauge: locate the repair port or exposed bolt at the joint and tighten appropriately with the appropriate tool—note: "moderate" is important; excessive force may cause thread slippage or internal structure fracture;
- Joint noise, dislocation, or complete inability to fix: This is an internal skeleton issue. Disassembling it yourself is basically equivalent to scrapping it. Contact the brand's after-sales service directly.
Prevention: Do not strike extreme positions, support the stress points when changing positions, and check screw tightness every 1–2 months.
Issue 2: Oily and sticky skin (mainly TPE)
Reason: TPE is inherently oily, and oiliness is a natural part of the material, which accelerates at high temperatures.
Treatment: Wash with warm water + neutral detergent→ dry the lint-free towel → dry thoroughly, then apply a thin layer of talcum powder or cornstarch to absorb oil. For severe stickiness, use specialized cleaners; do not use alcohol, makeup remover, or organic solvents, as they can directly damage the material.
Prevention: Store at controlled temperature and away from light (15–25°C), and apply powder every 2–4 weeks.
Issue 3: Small cracks and scratches
- Silicone model: You can purchase a special silicone repair agent and follow the instructions. After repairing platinum silicone, it basically does not affect usage;
- TPE version: Difficult to repair, and the "TPE glue" on the market is limited in effect and carries the risk of enlarging the wound. Keep small cracks clean first to prevent tearing and spreading; major damage should be handled directly through after-sales service.
Question 4: Staining
- Light staining: TPE can be tried with baby oil or specialized decolorizing products for gentle wiping; Silicone color-removing paste;
- Deep dyeing basically cannot be completely removed—this problem can only be prevented: wash new clothes first, wear only light colors, and don't let dark clothes fit too tightly overnight.
Question 5: Indentations
(caused by prolonged lying or sitting): After changing positions, apply a warm water bottle not exceeding 45°C to the indentation area to help the material rebound. Most cases recover within a few days. Deep marks formed by long-term pressure may remain permanently—so "changing postures often" is always the top priority when storing.

—these are things you should confirm before buying
Warranty period for the frame, after-sales policies, whether repair services are provided, and supply of spare parts (inner liners, joints)—these four factors directly determine the repair experience years from now and are far more important than saving hundreds of yuan back then.
Summary in one sentence
: oil release, powder sprinkling, warm compress on the indentation, tighten with a large amount; Cracks, dislocations, and deep staining are left to after-sales service. Clearly defining boundaries saves money and prevents small issues from turning into big ones.
