Welcome to GoodBed!

Many companies make a topper with CoolGel Foam. We make one in our store at Nest Bedding but if you search the net, many companies do.

I hate seeing people throw good money at bad. When a bed starts sagging, as it sounds like yours is doing, putting a topper on it means you will soften up the bed, but the topper will follow whatever sagging the mattress is doing. And they sag usually because the low density foam in them tend to wear quickly.

Good luck!

I concur, a mattress topper is great for a firm mattress, but most of them will not do anything for support. Since you have a Serta, you should look into contacting the manufacturer you may have some $$$ left on your warranty, if you have not voided any terms and conditions. Double sided mattresses are nothing special, I can go on and on, but most companies make double sided mattresses for hotels only. Which there is a very good reason.

Good Luck!

A latex topper sleeps cool. If you also need support, get a 2" Dunlop. You can see and order one here.

We're sorry to hear you're not enjoying your mattress. We recommend contacting the store of purchase or Serta (888-55-SERTA) for warranty service to see if there is an issue we can help resolve.
