Need king Sized Bed info. / reviews/ opinions!!!....Thanks!!!

Within a 2 - 4 weeks I will be deciding on a new king sized! Currently have a queen sized memory foam bed. I sleep on my back, very rarely on my side or stomach.
What are the top king memory foam beds?
What are top quality / economical brands?
How’s the order time to delivery on beds these days?
What’s the general markup? 5%, 10%, 20%?
My prefers a spring bed. Are there combo beds?
How does a memory foam topper on a spring bed compare to an all memory foam bed?
Online or in-person stores I should be wary of or make better deals?
***I am doing my own research soon but inundated with moving so I have soooo much other work that needs to be addressed and time is short… any insight, reviews, opinions are appreciated!

What are the top king memory foam beds?

A bit biased here on that question to be able to answer.

What are top quality / economical brands?

really should look at whats in the mattress and compare weight for what your really buying. Not just what they say its worth for the price tag

How’s the order time to delivery on beds these days?

Be careful on this. some have major delays.

GhostBed ships in 24 hours. If your moving let us know to give us a window and we can deliver it.

What’s the general markup? 5%, 10%, 20%?

It depends again on what your buying for the quality of the material and craftsmanship.

My prefers a spring bed. Are there combo beds?

if you like spring upgrade to hybrid for spring and memory combo.

How does a memory foam topper on a spring bed compare to an all memory foam bed?

topper is an add on to get an extra life out of your current mattress in most cases. a new mattress should help get you to sleep.

Online or in-person stores I should be wary of or make better deals?

It does not hurt to ask. GhostBed has a coupon here on MU
