Max Coil luxury extra firm Single mattress in Upper East Coast Road, East Singapore for sale

The mattress originally cost me $390. It is very firm and very clean.
It is anti-dustmite and anti-fungal. It has no stains.
It is a few years old, but I have been studying overseas, so it has rarely been used. It has been kept in a very good and clean condition, under bedsheets and a mattress protector, in a well-maintained room.
Available for self-collection now. Please contact me at 90035790 for address details. Thank you.
(The stuff toys are not for sale.)
If you would like to buy the bed frame, here are some details:
It is from Slumberland, original price of $790. I still have the receipt. Full suede headboard and sides. All surfaces, legs and stuffing are in excellent condition. It has no stains or scratches. The fabric is soft and smooth, and the bed has no sharp corners. The frame is very sturdy.
It has sentimental value, but I am willing to negotiate a reasonable price.
