by This one splits cleanly by body type. The Brooklyn Bedding Titan Plus is a specialist — purpose-built firm support for heavier and plus-size sleepers, and genuinely good at exactly that, as our Titan review concluded. The Amerisleep AS3 is the all-rounder: zoned HIVE support and a true-medium Bio-Pur feel that suits average-weight back, side and combination sleepers — the profile the Titan is frankly too firm for. Match the bed to the body and neither disappoints.
Our Pick for Most Sleepers
Amerisleep AS3
HIVE 5-zone support · 100-night trial · 20-year warranty
A specialist and a generalist
The Titan Plus exists for one demographic: heavier sleepers who compress ordinary mattresses into hammocks. Its reinforced coils and firm surface are calibrated for serious loads — our review called it « purpose-built for exactly that », and warned that lighter or side sleepers will find it far too firm. The AS3 approaches support the opposite way: instead of uniform firmness, its HIVE layer zones the push-back — softer where shoulders need give, firmer under the hips — which is why it fits the widest range of average-weight sleepers.
| Amerisleep AS3 | Brooklyn Bedding Titan Plus | |
|---|---|---|
| Built for | Average-weight back, side & combo sleepers | Heavier / plus-size sleepers |
| Feel | True medium, zoned | Firm, uniform, high-capacity |
| Construction | Bio-Pur foam + HIVE transition | Reinforced coil hybrid |
| Trial | 100 nights | Direct trial (Brooklyn terms) |
| Warranty | 20 years | 10 years typical |
The honest split
If you are well above average weight, buy the specialist — the Titan’s firmness is a feature, not a flaw, and the AS3 is not chasing that duty cycle. For everyone else the Titan is a plank: our review was blunt that lighter side sleepers will bounce off it. The AS3’s zoning, cooler plant-based foam and longer coverage make it the obvious default for typical bodies.
Who should buy which
Buy the Amerisleep AS3 if you are an average-weight sleeper who changes position, values shoulder relief, and wants the longest warranty on the table.
Buy the Titan Plus if you are a heavier sleeper who has flattened softer beds before — that is precisely the problem it was engineered to solve.
Verdict
No loser — just two different briefs. The Titan owns its niche; the AS3 owns the middle of the market with zoned support, cool foam and a 20-year signature. Buy by body type and both deliver.
Bottom line: match the bed to the body.

Frequently asked questions
Is the Titan Plus too firm for side sleepers?
For most, yes — our Titan review flagged lighter and side sleepers as the wrong audience. The AS3’s zoned shoulder give is built for exactly them.
At what weight does the Titan make more sense?
It targets plus-size sleepers who have experienced sagging on standard beds. If that has never been your problem, you are probably the AS3’s customer, not the Titan’s.
Which lasts longer?
Coverage tells the story the brands believe: 20 years on the AS3, half that on typical Brooklyn models — though for genuinely heavy loads, the Titan’s build is the one designed for the stress.
