Why is my dining table not selling and even my beds?

I am trying to sell my dinining table - paid £2000 back in 2008 and trying to sell for £150 online - not one person is interested! Its real oak wood + small table to complement + four chairs!

And also trying to sell my two beds - one double bed + one king size bed - with matresss too again no one online is interested even for £150 for both -

The advert is also only for collections. Are people not interested in buying these things as second hand?

p.s. they are all in excellent conditions.
